This year, Las Vegas, Nevada broke its all-time heat record, reaching 120° F.
The temperature was recorded at Harry Reid International Airport on July 7, 2024. That week, between July 6 and July 12, was the new hottest 7-day period on record, with an average high temperature of 117.5° F.
This is the daily reality for Vegas residents in the summer. Record-breaking temperatures are hard to bear, but so were all the hot days and nights that came before. Commuters frequently see temperatures above 120 flash on their vehicle dashboards, and outdoor workers struggle to do their daily tasks under the hot sun.
“There’s a disconnect between climate science and the people who live here,” says Woodwell Climate Research Associate, Monica Caparas. “Vegas residents know our summers are hot and unbearable. Understanding climate change is driving the extreme weather we’re experiencing is where the disconnect lies. ”
Caparas moved to Las Vegas as a child. She grew up there, left for college, and returned to settle into her adult life. Today, she works for Woodwell Climate’s Risk team remotely from her home in the city. Caparas knows the ins and outs of local life. These include Vegas’s rapid population expansion, the groups of people experiencing homelessness sheltering in underground stormwater infrastructure, and the heat that was unbearable before it started making headlines.
Experiencing climate change without shelter
Caparas’s work with the Risk team aims to provide communities like Las Vegas with an accurate picture of the climate-driven changes in their future. These “risk assessments” are provided through Woodwell Climate’s Just Access program, which uses the most accurate climate models, in collaboration with local knowledge, to anticipate future community safety threats. The analyses have brought to light growing threats from flooding, heat, storms, and more. The team provides assessments, free of charge, to states, cities, and countries across the world.
Just Access serves what Risk Program Director Christopher Schwalm calls “frontline communities.” The term describes groups of people who are over-exposed, under-resourced, underserved, historically marginalized, and therefore the most at-risk to the repercussions of climate change. In the risk assessment for Las Vegas, people experiencing homelessness are front and center.
“Between May 20th and the first week in July, about 20 people who were experiencing homelessness died of heat,” says Dr. Catrina Grigsby-Thedford, Executive Director of the Nevada Homeless Alliance (NHA) and community partner in Las Vegas.
The NHA estimates that almost 8,000 people are experiencing homelessness on any given night in southern Nevada. The number is only growing. Grigsby-Thedford says that this year’s unhoused population is up 1,300 people compared to 2023.
“Often our shelters are full,” Grigsby-Thedford says, “We’re limited by shelter beds and space.”
The NHA’s shelters do open all day in extreme heat, but so many people packed tightly together is still unsafe.
With nowhere to go, some seek shelter underground in Las Vegas’s stormwater infrastructure. While the tunnels are cooler out of the sun’s reach, they are at risk from flooding. Across the region, extreme precipitation is expected to increase by 12-14% by 2050, raising flood risk in the city and especially within the tunnels.
To combat lack of space and shelter, the NHA hosts 4-8 one-stop resource fairs per month. The events, called Project Homeless Connect, serve both people experiencing homelessness and low-income residents in Las Vegas. Grigsby-Thedford says these events “fill in gaps”—offering housing assistance, medical care, hygiene care, and other resources.
Despite all of this work, many unhoused people are hesitant to engage with organizations like the NHA. Grigsby-Thedford says “choice is often a challenge,” and that when people grow accustomed to the way things are, they often accept it and choose to stay.
Picturing risk
Building trust with communities, especially those predisposed to mistrust outside actors, is essential in this work. Which is why, Schwalm says, Woodwell Climate approaches risk work with the goal of “meet[ing] people where they are.”
That means “scoping,” the team’s word for listening to what community and government leaders want out of the risk analysis—what concerns they have, weak points they’ve identified, and what help might be needed post-analysis.
“Two-thirds of the time we spend from start to finish falls into this scoping idea, rather than doing analysis itself,” Schwalm says.
Scoping frames the data the risk team collects, as well as who their partners will be during the risk analysis process.
“We find people who are practical and recognize that there’s a problem,” Schwalm says, “We only work with communities who want to work with us.”
Following the scoping process, the Risk team compiles an analysis of extreme weather events and subsequent risks each community will face as climate change progresses.
“We perform a stress test of that particular geography to identify weak points,” Schwalm explains.
Then, the Risk team uses the most up-to-date climate models possible to predict changes in extreme weather and regional climate. By using predictive models, the team focuses efforts on what the future will hold, as opposed to using past strategies.
“We need to use the future to predict the future,” Schwalm says simply.
Making climate risk data accessible to all
Over the past three years, Just Access has provided 50 communities—that’s about a quarter billion people—with risk analyses. These communities span the U.S., Central and South America, Africa, Asia, and Oceania. They’ve worked with countries, like the Democratic Republic of Congo, where they helped update the country’s National Adaptive Plan, states like Chiapas in Mexico, groups like Cree Nation in Canada, and other communities, now including Las Vegas.
Despite all of this work, though, Schwalm says there is still room to grow.
“Fifty communities is kind of only a drop in the bucket,” he says, “We’re not going to make a huge dent in this unless we move beyond working community-by-community.”
Two major roadblocks for Just Access are finite resources: time and money. Individual risk analyses require a lot of time and communication to address risks in relatively small areas.
The other obstacle, money, is something climate research could always use more of. Grants and donations are crucial in order for analyses to remain free, and those sometimes come with limitations.
“There’s a tension from the funder to work in a specific geography sometimes,” Schwalm says, “It’s a juggling act.”
Climate change can also be a politicized topic. In order to meet people where they are, sometimes the Risk team implements changes in language used to communicate with community leaders. This can be a change as simple as using “extreme weather” instead of “climate change.” As long as everyone in the room is ready to confront what the future holds, they’re all working on the same page towards the same goal.
“We’ve done red states, blue states, rural, urban,” Schwalm continues. “We’ve learned how to read the room.”
Creating the foundations for change
Woodwell Climate’s involvement in Las Vegas brings to light the way justice issues, like homelessness, interact with growing threats from climate change.
“In the Las Vegas risk assessment, we are focusing on the disproportionate impacts of the climate crisis on communities already facing systemic socio-economic inequity,” says Caparas. “We must think about intersectionality in order to address climate justice.”
Not only does climate change represent a current crisis for those experiencing homelessness, communities with fewer resources are now at greater risk of being made homeless by future climate-related disasters. Accurate climate risk information can support organizations like NHA as they develop strategies to serve people experiencing homelessness in a more extreme future.
Grigsby-Thedford says that NHA members, especially those with lived experience of homelessness who work as Lived X Consultants, are always looking to be involved in projects like the one Caparas leads.
“We always talk about weather in our meetings,” she says, “So this is perfect, someone’s actually doing research about this. Anything that impacts [Las Vegas’s homeless population], we want to make sure we’re involved in that.”
For the Las Vegas risk assessment, Caparas is working with the NHA and Southern Nevada Lived X Consultants to understand climate risks around cooling stations in public buildings, which are a vital, air-conditioned shelter when the heat index is too high. Grigsby-Thedford says there were many more cooling stations in 2023 and 2024 compared to previous years.
Caparas also forged a connection with Miguel Dávila Uzcátegui, Southern Nevada’s Regional Transportation Commission (RTC) Senior Planner and board member of Help Hope Home. Together, they are developing a database of flooding infrastructure and updating the city’s flooding model with future climate projections. The RTC will integrate the Risk team’s model into regional planning work, updating Las Vegas’s flooding and transportation infrastructure for community safety.
None of this work would have been possible without Caparas’s diligent bridge building between the scientific resources of Woodwell Climate and the needs of people in her own community. Those connections allow science to be informed first and foremost by those most affected by climate change.
“The people closest to the problem are the people closest to the solution,” says Grigsby-Thedford.
On Wednesday, September 25, 2024 at 10:00 a.m EDT, representatives from Woodwell Climate Research Center and IPAM Amazônia joined Governor of Pará, Brazil Helder Barbalho, for a special Climate Week event to explore the impacts of climate change on the state of Pará, and launch a new partnership to develop an in-depth climate risk assessment for the state that can inform local adaptation plans and solutions.
“Three years ago, Woodwell Climate partnered with the UK COP 26 Presidency on research that showed the lack of access to tailored, actionable climate risk information was a critical barrier to climate mitigation and resilience planning at the national and sub-national level,” said Dr. Wayne Walker, Chief Scientific Officer for Woodwell Climate Research Center. “Now, we are proud to be partnering with next year’s COP 30 host on work that provides a clear example of how to bridge this important information gap for the state of Pará.”
In 2021, Woodwell Climate and IPAM conducted an initial climate risk assessment for Belém, the capital of Pará and host of next year’s UN climate negotiations, COP30. The study found that the hottest months in the region are getting hotter, and a growing number of days per year are hitting dangerously high wet-bulb – or “feels like” – temperatures, increasing risk of severe heat stress, especially in a city where most economic activities take place outdoors. It also found that the fire season in Pará is getting longer, exposing local communities to extended periods of worsening air quality. A new, more comprehensive climate risk assessment, the initial results of which were presented during Wednesday’s event, shows that Belém is, and will continue to be, at high risk of severe flooding.
“If climate change continues on its current path, Pará will face crises on multiple fronts—with forests devastated by drought and fire, and cities facing devastating extreme heat and flooding,” said Dr. Ludmila Rattis, Assistant Scientist in Woodwell Climate’s Tropics Program. “The roots of these challenges are global and understanding that can drive urgent action to both reduce greenhouse gas emissions and begin necessary adaptation efforts.”
Through this new agreement, Woodwell Climate, IPAM Amazônia, and the Pará government will build on the findings of these assessments to analyze the climate risks facing the Pará region and co-develop effective climate solutions to address them, including identifying areas where green infrastructure could be implemented, pathways to transition to new, more sustainable economies in Pará and across the Amazon, and other mitigation and adaptation strategies.
“The quality of science to support decision-making is fundamental,” said Governor Helder Barbalho. “As the capitol [of Pará] and as the host city of COP30 next year, Belém at this moment has the opportunity for major infrastructure works that will not be the whole solution, but certainly can improve water management, sanitation management, macro-drainage infrastructure to maintain the character of a city surrounded by rivers.”
As a part of this effort, Woodwell Climate will also work with IPAM and the Pará government to develop a case study, as a part of Woodwell’s Unlocking Land-based Opportunities for Climate Solutions (UnLOCS) initiative, to investigate how to effectively scale nature-based climate solutions in Pará leveraging mechanisms like the voluntary carbon market, with the goal of dramatically reducing emissions from land use while delivering meaningful benefits to local communities, ecosystems, and economies.
“We cannot imagine that looking at the forest requires [only] public policies for the forest,” said Governor Barbalho. “We need to be able to look at the forest, but know that the impact of them will require us to act in urban centers.”
“I want to reaffirm IPAM’s commitment to this partnership that we have had with the government of Pará, the State of Pará, and the people of Pará,” said André Guimarães, Executive Director of IPAM Amazônia (Amazon Environmental Research Institute). “We have to work collectively. There is no single solution to the problems we are facing today.”
“This is an incredible opportunity to focus the world’s attention on tropical forests, on Brazil, on Pará,” said Dr. R. Max Holmes, President and CEO of Woodwell Climate Research Center. “We all understand that the Amazon is an incredibly important region, not just for Brazil and for the people that live there, but for the entire world—for all of us.”
Hurricane season in North America is underway. Already, the second storm of the year to earn a name, Beryl, has cut a destructive swath across the Caribbean and the United States. This year, the National Oceanic and Atmospheric Administration (NOAA) forecasted an extremely active hurricane season, anticipating between 17-25 named storms (the average is 14) and 4-7 major storms (average is 3). Major storms are category 3 and above with wind speeds exceeding 111 mph.
Intense seasons like this are likely to be a more common occurrence in a warmer world, as higher temperatures, rising seas, and changing weather patterns create the conditions for bigger, more destructive, longer lived, and more rapidly strengthening storms. Here’s how climate change is affecting the Atlantic hurricane season:
1. Higher temperatures mean more energy to form hurricanes
To understand how hurricanes are being affected by climate change, it’s important to understand how hurricanes are formed. They are essentially clusters of thunderstorms, building strength as they sweep westward using the energy from warm tropical waters. Under the right conditions, the Earth’s rotation will cause the cluster to spin into a cyclone shape. Because heat is energy, increases in sea surface temperatures play a critical role in strengthening these storms.
The ocean is a major heat sink for the planet, absorbing over 90% of the excess heat trapped by greenhouse gasses in the Earth’s atmosphere over the past few decades. Global sea surface temperatures have increased approximately 2.8F since the beginning of the 20th century, and ocean heatwaves — large areas of above-normal temperatures that can last for months-– are much more common and widespread. A hotter ocean means there is more energy available to fuel tropical storms, ultimately making it a more destructive event when it hits land.
2. The hotter the air, the more water it can hold
The second thing a hurricane needs to form is moisture. Water is evaporated and pulled up into the developing storm as it spins across warm waters of the tropical Atlantic. Hotter air temperatures mean more moisture can be held as vapor in the atmosphere, which allows storms to ingest greater amounts of water that will eventually condense into clouds and be released as rainfall. Condensation also releases heat into the storm, fueling its intensification. Models estimate that human-caused global warming has increased hurricane extreme hourly rainfall rates by 11%.
3. ENSO fluctuations are becoming more extreme
Climate change is also contributing to larger swings between the two phases of the El Niño Southern Oscillation (ENSO)—meaning stronger versions of both El Niño or La Niña patterns. Currently, the Atlantic is headed towards a La Niña, which favors hurricane formation because it lessens vertical wind shear. Differences in wind speeds at different heights in the atmosphere can tear a storm apart, while less shear (more consistency in wind speeds between altitudes) allows storms to stay together and build strength.
4. Tropical storms are undergoing rapid intensification more frequently
All these factors add up to more intense tropical storms in a world altered by climate change— meaning more category 3-5 storms and more big storms back-to-back. Since 1975 the number of category 4-5 cyclones has roughly doubled.
This doesn’t necessarily mean that there will be more hurricanes; however, the ones that do form can be bigger and cause more damage (on top of the already estimated $2.6 trillion in damages since 1980.) If anything, data shows a slight decrease in the number of storms, moving more slowly along their path, releasing their extreme wind and rain over a single location for longer periods.
5. Rising sea levels are making hurricanes more deadly
Sea level rise due to climate change has also made hurricanes a more dangerous threat for more people. As sea levels rise, coastlines are put at increased risk of flooding.
Sea levels have risen roughly 8 in since the late 19th century, and the rate of rise is accelerating as climate change worsens. When a hurricane makes landfall, water is pushed inland by high-speed winds in an event known as storm surge. Every additional inch of sea level rise allows the surge to travel farther inland, threatening a wider area and causing more damage, death, and injury— especially in areas where human development along the coast has exposed people and homes to greater risk.
As temperatures continue to rise, communities along the East and Gulf coasts can expect to be hit harder by destructive storms. Despite this, more and more people are choosing to live and build along the coasts, increasing the cost of damages when hurricanes do strike. Slowing warming temperatures and building adaptation measures to protect coastal communities will become more urgent as Atlantic hurricanes intensify.
We can all agree 2023 was a weird year for weather, right? The United States set a record for the number of billion dollar weather disasters. A major Amazon River tributary reached its lowest water levels in a century during extreme drought. Extreme rain in Libya caused two dams to break, destroying homes and killing over 4,000 people.
And then, of course, there was the heat. 2023 was the hottest year on record. Countries around the world saw heat records fall month after month. The Arctic was hot. The ocean was hot. And debates swirl on about whether we’ve already passed critical warming thresholds.
So how do we put 2023 in context of the greater trend of warming? Here’s what some of Woodwell Climate’s scientists have to say about last year’s record-breaking events.
Did the models predict this?
The dramatic scenes of heat and extreme weather last year prompted many to ask why temperatures had seemingly spiked way above the trend line. Was this unexpected? Was it out of the range of what scientists had modeled? Woodwell Senior Scientist, Dr. Jennifer Francis says not entirely.
“Almost exactly a year ago,” says Francis, “we had just come out of three years of La Niñas and we came close to breaking global temperature records then, even though La Niñas tend to be cooler than neutral or El Niño years. And then along came the strong El Niño of 2023.”
El Niño and La Niña are two extremes of a natural phenomenon that impacts weather patterns across the Pacific, and around the world. In an El Niño year, the prevailing trade winds that normally push warmer waters into the western tropical Pacific—allowing cooler water to well up along the western coast of the Americas—are reversed, resulting in hotter ocean surface temperatures in the eastern equatorial Pacific. When the ocean is hotter than the air above it, that heat is released into the atmosphere, often making El Niño years record breaking ones for global temperatures.
“Last year’s spike looks a lot like the last big El Niño event in 2015-2016. It’s just that now the whole system is warmer. So to me, it wasn’t at all a surprise that we smashed the global temperature record in 2023,” says Francis.
The spike put global temperatures far above the average of climate model simulations, but that doesn’t mean the models didn’t account for it. Risk Program Associate Director, Dr. Zach Zobel, says that averages tend to smooth out natural year-to-year fluctuations, when in fact the upper and lower ranges of model predictions do encompass temperatures like the ones seen in 2023.
“It was well within the margin of error that you would expect for natural variations,” says Zobel.
How does ocean heat impact the climate?
One element of last year’s heat, one that wasn’t necessarily forecasted, was the simultaneous appearance of several ocean heat waves around the globe. The ocean absorbs the vast majority of heat trapped by greenhouse gasses, and that heat can be released under the right conditions. El Niño is one example, but in 2023 it coincided with other not-so-natural marine heat waves across the world.
“In pretty much every single ocean right now there are heat waves happening, which is something quite new,” says Francis.
A couple of dynamics could be driving this. One possibility is that, after three years of La Niñas, in which equatorial Pacific ocean temperatures were generally cooler than the air, the ocean simply absorbed a lot of heat, which was then primed to be released in an El Niño year. Another, Zobel suggests, could be recent shipping laws that required shipping vessels to eliminate sulfate emissions by 2023. Sulfates are a pollutant that may have been helping bounce back solar radiation, hiding the true extent of warming.
“Usually when there’s an El Niño, the eastern tropical Pacific is very warm, but it doesn’t actually drive up ocean temperatures everywhere,” says Zobel. “That was the biggest surprise to me: how warm the northern hemisphere of the Atlantic and Pacific were for most of last year and into 2024.”
Ocean heat waves are typically long-lived phenomena, lasting many months, and so can be a useful tool for meteorologists looking to predict 2024’s extreme weather events.
“The good news is that it provides some kind of long-term predictability about weather patterns in the upcoming year,” says Francis. “The bad news is that they tend to be unusual weather patterns, because those ocean heat waves aren’t usually there.”
Will next year be hotter?
So are we in for another, hotter year after this one? Risk Program Director Dr. Christopher Schwalm says it’s likely.
“Warming predictions for 2024 from leading scientists all forecast a higher level of warming this year than last year,” says Schwalm.
Already, March 2024, was the 10th month in a row to break temperature records. Zobel says it’s typical for the year following an El Niño peak to maintain high temperatures.
“Because the ocean spent a good amount of the year last year warmer than average, that energy is typically dispersed throughout the globe in the following year,” says Zobel. “So even though the tropical Pacific might return to normal, that energy is still in the system.”
However, atmospheric scientists are already seeing signs that El Niño is slowing down and flipping to its counterpart, La Niña, adding another layer of complexity to predictions for 2024.
“The 2024 hurricane season is a large concern,” says Zobel. “La Niña is a lot more conducive to tropical cyclone development. If we combine above average numbers with the amount of energy that storms have to feed on, it’ll be a shock to the system.”
What does this mean for 1.5?
In the discussions around 2023’s temperatures, one number dominates the conversation: 1.5 degrees C. This is the amount of warming countries around the world agreed to try to avoid surpassing, in accordance with the United Nations’ 2015 Paris Climate Agreement. Estimates from Berkeley Earth say that 2023 may have been the first year spent above that threshold.
This assertion may take several years to verify— one year spent physically above 1.5 degrees of warming does not indicate the UN threshold has been permanently passed. What scientists are looking for is a clear average trend line rising above 1.5 degrees C without coming back down, and for that you need several years of data. That, regrettably, creates a lag time between climate impacts and updating climate policy. But, for many, the debate around the arbitrary 1.5 degree goal has become a distraction. Schwalm says scientists and policy-makers should be focusing on urgently combating climate change whatever the numbers say.
“We are already living in a post-Paris Agreement reality,” says Schwalm. “The sooner we admit that and reimagine climate policy, the better.”
“Actual real world impacts are going to be there, whether we’re at 1.48 or 1.52,” says Zobel.
And Francis agrees. “There are so many indicators telling us that big changes are underfoot, that we are experiencing major climate change, but reaching 1.5 isn’t going to all of a sudden make those things worse. It’s just one more reminder we’re still on the wrong track and we’d better hurry up and do something.”
Drought, driven by a combination of El Niño and climate change, has disrupted shipping through the Panama Canal in recent months. Dropping water levels in Lake Gatun forced Panama Canal authorities to pose restrictions on the number of ships that can pass the canal, dropping from the normal 38 down to 24 transits a day by November 2023, causing long queues at nearby ports as ships wait their turn to pass. If the restrictions remain in place through 2024, there could be up to 4,000 fewer ships—with cargo ranging from children’s toys, to solar panel components, to life-saving insulin—passing the canal in 2024. Delay and disruption along shipping routes will only become a more common occurrence in a warmer world. These 7 graphics show how drought threatens serious disruptions to the global supply chain.
1. Panama in Drought
Panama is currently suffering a prolonged drought that began in early 2023 and has not let up. In October, rainfall was 43% lower than average levels, making it the driest October since the 1950s. For the area around the canal, 2023 was one of the driest two years since record keeping began in the country.
2. El Niño-driven dryness exacerbated by climate
Panama’s severe drought is being exacerbated by the double-whammy of a strong El Niño and record-breaking global warming— exceeding the pre-industrial temperature average by 1.35 C. El Niño is a natural climate fluctuation that brings warmer-than-average air and ocean waters to the West coast of the Americas. That influx of warmth can vary in strength and last between nine and twelve months, and the National Oceanic and Atmospheric Administration (NOAA) predicts it will continue into at least April of 2024.
The severity of El Niño fluctuations is linked to climate change. Climate modeling shows swings between El niño and its counterpart La niña have been growing more extreme, resulting in the more frequent and intense events seen in the past few decades Under high emission scenarios, in which we don’t get warming in check, El Niño events could become 15-20% stronger.
3. Gatún Lake levels continue to drop
The drought has had a particularly profound effect on the man-made Gatún Lake, which holds the water supply that operates the Panama Canal. On January 1, 2024 water levels in Gatún Lake were lower than in any other January on record, almost 6 ft lower than January 1, 2023. Millions of gallons of water from Gatún, along with other regional lakes, are used to fill the locks that raise ships above sea level for the passage over Panama’s terrain. Insufficient water supply jeopardizes ship passage
Not only does Gatún Lake feed the locks that power the Canal, it also supplies drinking water to millions of residents in the central region of the country, including two major cities: Panama City and Colón. As both Panama’s population and the scale of global shipping has grown, there has been greater demand on the lake for freshwater.
4. Less water means fewer, smaller ships
In response to dropping water levels, Panama Canal Authorities have been forced to institute restrictions on ship passages. Ship transits are currently limited to 24 per day until April of 2024, when the authorities will re-evaluate at the start of the rainy season. The number of ship passages was 30% lower than usual by the end of 2023. The unreliability of transit through Panama has already prompted some ships to re-route.
Lower water levels also restrict the size of ships that can pass through the canal, as larger, heavier vessels sit lower in the water, putting them at higher risk of running aground in shallower waters. Large ships also require more lake water to lift them in the locks. As global shipping volume has grown, many shipping fleets have, too— relying on massive vessels that can carry more goods, but are harder to navigate through shallow waterways like the Panama Canal.
5. Disruptions in Panama affect global trade
The Panama Canal accounts for 5% of global shipping, so disruptions here affect the worldwide supply chain, resulting in delayed shipments, more fuel usage, and GDP losses.
The impacts of shipping disruptions in the Panama Canal are also being compounded by political events in the Red Sea. The Suez Canal, an alternative route for ships bound between Europe and Asia, has also had shipping disrupted by attacks from the Houthis, a Yemeni military group targeting Israel-bound ships. With both the Panama and Suez Canals becoming less reliable routes, more ships will be forced to take the long way around— traveling down to the southern points of Africa and South America.
6. Arctic ship travel does not offer an alternative route
Far to the north, another waterway is being rapidly altered by climate change. As the Arctic warms faster than any other place on the planet, summer sea ice has been disappearing at a rate of almost 13% per decade. This has opened up new lanes of ice-free water that some countries are eying as potential new routes. But navigating through a melting Arctic is still dangerous, and the majority of new ship traffic in the Arctic is comprised of smaller military or fishing boats, rather than the large shipping vessels used to carry commercial cargo.
Furthermore, increased ship traffic in the Arctic has the potential to further emissions, as melting ice could open up access to new sources of oil and natural gas— perpetuating climate warming.
7. Temperatures are still rising
Though December rains saved Panama Canal officials from instituting further restrictions on ship passage, the region is still experiencing El Niño, and sea surface temperatures in early 2024 have continued to climb higher than 2023. Each day in 2024 has recorded the highest temperatures on record for that calendar date. The only path to stabilizing global shipping lies in stabilizing the global climate.
1. Collaborating with Communities
This year, Woodwell Climate’s Just Access Initiative went global. Just Access works in close partnership with communities to provide tailored, actionable climate risk reports for Rio Branco, Brazil; Addis Ababa, Ethiopia; Summit County, Utah; and Lawrence, MA. At COP28, Just Access released their latest report in collaboration with the Ministry of Environment and Sustainable Development of the DRC, which focused on climate risks and potential solutions in the country and identified carbon markets as a potential funding mechanism for adaptation efforts.
Just Access collaborates with local officials and advocates to ensure the final reports cover information critical to their community’s planning. So far, 14 reports have been completed and more are on the way.
Read the report.
2. Tongass National Forest Protection
In January of 2023, the Biden Administration restored protections against logging and road-building for more than 9 million acres of the Tongass National Forest, the world’s largest intact temperate rainforest.
This came after Woodwell Climate’s Dr. Wayne Walker and Geospatial Analyst Seth Gorelik, along with long-time collaborator Dr. Dominick DellaSalla of Wild Heritage, delivered a research report to the Biden administration showing massive carbon stores in Tongass National Forest and highlighting the importance of roadless areas.
3. Citizen Science with Science on the Fly
In 2023, Science on the Fly’s (SOTF) focused their activities on stewarding their community of scientists. Together they collected more than 3,000 water samples from hundreds of locations around the globe. SOTF leverages the passion and dedication of the global fly fishing community to gather data on the health of rivers across the world. With this data, SOTF can improve our understanding of how watersheds and river systems change over time due to climate change and local effects.

4. Training the Next Generation of Researchers
We sent 10 Polaris Project students into the field this summer. The Polaris Project engages the brightest young minds from a diversity of backgrounds to tackle global climate research in one of Earth’s most vulnerable environments: the Arctic.
Students conducted their own research projects over two weeks at a field research station near Bethel, Alaska. Afterwards, they returned to the Center to analyze samples, and presented their findings at the American Geophysical Union meeting in December.
Woodwell Climate also hosted several interns through the Partnership Education Program. These undergraduate students participated in research and communications activities across the center.

5. Convening Critical Conversations
Woodwell Climate has been conducting tropical forest research in Brazil for nearly two decades alongside partner organization IPAM Amazônia. This year, Water Program Director, Dr. Marcia Macedo and collaborators, including Dr. Ane Alencar of IPAM, convened a multi-day workshop in Brazil that produced a policy brief on forest degradation. They then organized experts to submit public comments on Brazil’s updated policy for controlling Amazon deforestation, which for the first time also addresses forest degradation.
Read the policy brief here.
Across the globe, Permafrost Pathways partner, Alaska Institute for Justice (AIJ), hosted a “Rights, Resilience, and Community-Led Adaptation” workshop on Dena’ina homelands in Anchorage, Alaska. The two-day workshop created space for Tribes to share their expertise with each other and connect face-to-face with federal and state government representatives to access resources and technical assistance.
Read more about the workshop.
6. Representing Our Expertise
Our experts showed up as thought leaders this year at several high profile events. As just a few examples, Woodwell Climate’s Arctic Program Director Dr. Sue Natali and Senior Science Policy Advisor Peter Frumhoff both spoke on panels alongside other leading voices in climate at SxSW in Austin, TX. Senior Geospatial Analyst, Greg Fiske attended the Esri User Conference, where his topographic map of Alaska garnered two awards. And Assistant Scientist, Dr. Ludmilla Rattis gave a talk at TED Countdown about her research on the role of Tapirs in rainforest restoration. (Recording coming in early 2024)
7. Making Headlines
Woodwell Climate team members showed up in over 5,000 media stories this year. Our scientific leadership provided quotes for a broad range of high profile climate stories in New York Times, Reuters, Boston Globe, CNN and Grist, just to name a few. Senior Scientist Dr. Jen Francis was quoted over 4.2K times, appearing in major news outlets like the Washington Post and AP News to provide accessible context about the links between climate change and extreme weather events.
8. Rebuilding an Arctic Research Station
Last fall, Scotty Creek Research Station in Canada—one of the only Indigenous-led climate research stations in the world—was almost entirely consumed by a late-season wildfire. Woodwell Climate’s Permafrost Pathways project is providing rebuilding support to the Łı́ı́dlı̨ı̨ Kų́ę́ First Nation. Project scientists Dr. Kyle Arndt and Marco Montemayor visited the site for two weeks this spring to restore an essential carbon monitoring tower.

Woodwell Climate’s President & CEO Dr. Max Holmes brought Woodwell Climate to the main stage of CERAWeek, Green Accelerator Davos, GenZero Climate Summit in Singapore, Climate Week NYC, and Mountainfilm Festival. He discussed cutting-edge climate science alongside notable figures like Bill McKibben and former Colombian President Iván Duque Márquez.Read about Dr. Holmes’ time at Davos.
On September 27th, Woodwell Climate scientists and policy experts from the Center for Climate and Security (CCS) conducted a briefing on climate security risks in Iran and Türkiye. The presentation, hosted in the Capitol, drew in a crowd of interested congressional staffers to learn more about the relationship between the worsening climate crisis and national security issues.
This was the second of two such collaborative briefings, following a presentation to members of executive branch agencies, including the State Department, Department of Defense, US Institute of Peace, National Intelligence Council, and the Special Presidential Envoy for Climate, earlier in the month. Alex Naegele, a postdoctoral researcher with the Climate Risk Program at Woodwell, presented the results of two risk analyses produced in collaboration with CCS. The analyses used model projections to examine the impacts of climate change on rainfall, water scarcity, and wildfire.
Security experts from CCS— Tom Ellison, Elsa Barron, and Brigitte Hugh— then provided insight into political and social issues in both countries that intersect with climate risks, creating potentially destabilizing effects. In Türkiye, for example, diminishing water resources have the potential to create cross-boundary conflicts if it’s perceived by downstream countries to be “hoarding” water for its own citizens.
The briefing was highly attended by congressional staff across the political spectrum from 27 different House and Senate offices.
“The congressional crowd can be different and you never know exactly what you’re going to get,” says Woodwell External Affairs Manager Andrew Condia. “But you could just tell by the questions, and sort of the attention to the presentation that this was a very relevant and interesting topic across the board. It was a much more bipartisan turnout than I was expecting.”
That turnout speaks to the broad interest in how climate change represents a growing threat to national security interests. By speaking on climate through a security lens, Woodwell scientists are able to broaden interest and attention on climate issues throughout various branches of the federal government.
“Through this collaboration with CCS, we’re able to use our science and forward-looking approach to highlight specific climate risks to the security community. It’s something that’s not widely practiced and it’s a unique position to be in,” says Naegele.
Woodwell and CCS are looking forward to expanding the scope of future climate security case studies to draw links between the impacts of climate change and disruption to other countries or even other social systems.
“It would be interesting to apply this same thinking to an analysis of a certain theme instead of country. Perhaps examining impacts on supply chains or food systems,” says Ellison. “There’s a ton of issues we’ve barely scratched the surface on.”
“There are so many cultural differences to consider,” notes Dave McGlinchey. “From how the meetings proceed, to specific local sensitivities, even down to Congolese humor. Even if I was cracking jokes in fluent French, it would be impossible to get the tone right. That’s why having someone like Joseph was so important.”
In July, McGlinchey, Chief of Government Relations at Woodwell Climate, traveled with members of the Center’s risk team to Kinshasa in the Democratic Republic of Congo for a two-day workshop. The Center has been involved in community work in the country for over 15 years, led in large part by Joseph Zambo, Woodwell’s policy coordinator in the DRC. This workshop represents the latest collaboration— an initial assessment of the country’s future climate risks. Congolese professors, scientists, and government officials joined to discuss gaps in the data and to develop adaptation strategies to be included in a final report later this year.
The workshop was facilitated by Zambo who, with poignant questions, stories to recount, and of course, a bit of humor, guided the group through the tough work of planning for the future.
Expanding access to climate risk data
The community risk work in Kinshasa is one of over 20 successful risk assessments conducted as part of Woodwell Climate’s Just Access initiative. The project produces free, location-specific climate risk analysis for cities and regions both in the US and abroad. The hope is that, by providing free access to quality data— something often offered by private companies at prohibitively high costs — Just Access can facilitate adaptation planning for under-resourced communities.
“With Just Access, we want to remove the barrier of cost for communities that want to understand the long-term risks they are facing because of climate change,” says McGlinchey. “Often these communities are the ones already facing climate-related challenges that will worsen as the century goes on.”
Guided by a community’s particular concerns, Woodwell’s Risk team works with available data on key climate risks—flooding, heat, water scarcity, fire— and uses models to construct an image of how those events are likely to change as global temperatures climb. In the DRC, water is a core concern, both in its absence, causing drought and crop failure, and in its abundance.
“Heavy rains cause horrific flooding in the city of Mbandaka almost once or twice a year,” says Zambo. “In the capital, heavy rains are also destroying homes, roads, electrical structures, and internet connections.”
The most pressing risks vary from region to region. Across the world, in Acre, Brazil, Senior Scientist Emeritus Dr. Foster Brown says, “the word here is ‘heat.’” In Homer and Seldovia, Alaska, increasing wildfire days featured heavily.
But improvements in data availability and resolution, as well as refinements of climate models, have made it possible to replicate assessments for a variety of risks in places as distant and different from each other as Homer, Alaska and Kerala, India. Risk assessments can offer both region-wide crop yield estimates and street-level maps of flooding for a single city district to inform community planning.
It’s about building trust
Key to the success of municipal-level work are relationships with people like Zambo, who can offer insights into the needs of a community that can’t be approximated from the outside. Each community is different— in what information they need to make decisions, their level of technical expertise, their governmental capacity to implement changes, and in the ways they prefer to work.
So, with each new assessment, the Risk team starts from scratch, building new relationships and listening to community needs. This process takes double time on the international stage, where a history of superficial NGO and academic involvement can overshadow collaboration.
“A main goal with these reports is trust,” says Darcy Glenn, a Woodwell Climate research assistant who organized a risk assessment and workshop for Province 1 in Nepal last year with help from connections from her master’s program. “Building trust in the models, and trust in the methodology, and in us. That’s been our biggest hurdle when working with municipal leaders.”
Building that trust takes time. Province 1 was one of an early set of communities who worked with Woodwell Climate on risk assessments. While local leaders were interested in flooding and landslide risk information, what they really wanted was to increase the capacity of their own scientists and government employees to conduct climate modeling themselves. So the project was adapted to meet that need by tailoring a training workshop. The process took over a year to complete but Glenn says, that’s relationship-building time that can’t be rushed.
It also highlights the importance of pre-established long term connections in the places we work.
“It’s one thing to go into a new community by yourself, it’s another to go in with someone who has been there 30 years and can help navigate,” says Dr. Brown. “You have to look for the key people who can help make things happen.”
Within Brazil, Dr. Brown is now regarded as one of these “key people”. He has been living and working in Rio Branco for over 30 years and his credibility as a member of the community helped facilitate an assessment of extreme heat risk in the region. In the DRC, Zambo has been working with Woodwell Climate on various projects for over a decade. Without their expertise to bridge cultural and language gaps, completing projects in Brazil and the DRC would not have been possible.
Working for the Future
After getting risk information into the hands of communities, then comes the hard work of putting it to use. For Dr. Christopher Schwalm, Director of Woodwell Climate’s Risk Program, “the goal of the risk assessments is to give communities every potential tool we can to build resilience for themselves and future generations. With access to the right information, the next step in the adaptation planning process can begin.”
In Rio Branco, Dr. Brown says speaking to the changes people are already noticing has helped individuals connect better to the data. He’s been using the context of heat and fire alongside information from their report to strengthen conversations about existing forest and climate initiatives, authoring an alert for the tri-national “MAP” region (Madre de Dios in Peru, Acre in Brazil, and Pando in Bolivia) about heat conditions and the implications for this year’s fire season.
He has also been introducing the information from the report to the community in other ways— teaching and speaking at events. According to Dr. Brown, widespread understanding of both near- and long-term climate risks will become more important for all communities as climate change progresses and impacts each place differently. Cities and towns will need reliable information to help them practically plan for the future.
“We’re trying to get people to expand their time ranges and start thinking about the future. And this report has helped,” says Dr. Brown. “Because the people who are going to see 2100 are already here. What will we be able to tell them about their future?”
