Geoengineering gains momentum, but governance is lacking, critics say

a view of earth from space

As climate change rapidly advances, with 2023 and 2024 vying for the hottest year on record, solar radiation modification (SRM) geoengineering strategies are gaining momentum as short-term climate fixes. These especially include proposals for the release of cooling aerosols into the Earth’s lower stratosphere.

But preliminary geoengineering efforts (represented by lots of computer modeling and a smattering of small-scale field tests) are proceeding against a backdrop of public mistrust and resistance, while also provoking urgent calls by experts for national and international policies and regulatory structures to govern this burgeoning field.

World’s forests failed to curb 2023 climate emissions, study finds

a view up into the canopy of a forest

Forests and other land ecosystems failed to curb climate change in 2023 as intense drought in the Amazon rainforest and record wildfires in Canada hampered their natural ability to absorb carbon dioxide, according to a study presented on Monday.

That means a record amount of carbon dioxide entered Earth’s atmosphere last year, further feeding global warming, the researchers said.

Arctic wildfire pollutants: Towards improving emissions estimates and developing tribally-led monitoring

Lead: Scott Zolkos
Collaborators: Brendan Rogers, Sue Natali, Kyle Arndt, Elise Sunderland (Harvard University)

Increasing wildfire activity in northern high-latitude regions is threatening global climate goals and public health. When organic matter in soils and vegetation burns, greenhouse gasses, fine particulates (PM2.5), and contaminants including mercury are released to the environment. Currently, there is sparse data for understanding how wildfires contribute to the northern mercury cycle, as well as gaps in infrastructure for monitoring PM2.5 in Alaska Native communities. This project will develop a network to measure and monitor the release of mercury and PM2.5 from wildfire, with an emphasis on peatlands. Leveraging ongoing work by Permafrost Pathways, the team will install mercury sampling equipment on existing eddy covariance flux towers across Alaska and Canada. Alongside Permafrost Pathways and their tribal partners, the team will also consult with Alaska Native communities in the Yukon-Kuskokwim Delta to co-develop a tribally-led air quality monitoring program.

Workshop: Innovative sensors and applications in environmental research

Lead: Kathleen Savage
Collaborators: Zoë Dietrich, Marcia Macedo

Many of the Woods Hole science community’s cutting-edge researchers, including several scientists at Woodwell Climate, are developing creative, do-it-yourself (DIY) tools using relatively simple components to further explore their research questions. However, despite the six institutions’ similar applications and geographic proximity, there are few opportunities for exchange and knowledge, both across Woods Hole institutions and more broadly with Cape Cod educational institutions. The project team will convene a one-day workshop to bring together aquatic, atmospheric, and terrestrial science researchers and educators from the Woods Hole science community and local community colleges. The event will focus on three main themes: development of new sensor systems that use existing technologies in novel ways; new data storage or transmission solutions; and community initiatives to facilitate continued creation and sharing of new technologies. Sessions will foster knowledge exchange, build networks, and develop community resources focused on innovative DIY research solutions, and a hybrid virtual option will be offered for oral presentations to broaden participation.

Soil Spectroscopy for Global Good network

Lead: José Lucas Safanelli
Collaborators: Jonathan Sanderman

The Soil Spectroscopy for Global Good (SS4GG) initiative is a collaborative network of hundreds of soil scientists and others focused on using soil spectroscopy as a means to generate high-quality soil data at significantly reduced costs. It was created in 2020 by the Woodwell Climate Research Center, the University of Florida, and the OpenGeoHub Foundation (the Netherlands) with support from many national and international institutions and researchers. SS4GG created and supports the Open Soil Spectral Library (OSSL), an open source of soil spectroscopy data, and a broad community of practitioners uses the library and collaborates on related science. This award will extend the activities of the SS4GG initiative with a focus on training and further engagement with the soil science community. The project team will continue to add data sets and new models to the OSSL, as well as engage with the soil science community by attending international conferences and providing a training workshop. The funds will also support hosting a visiting soil biogeochemist at the Woodwell Climate campus—Dr. Raj Setia from the Punjab Remote Sensing Center.

Pathways of carbon metabolism under cover crops

Lead: Taniya RoyChowdhury
Collaborator: Jonathan Sanderman

Sequestering, or capturing carbon in soils has a high potential to mitigate climate change. It is challenging to specifically predict how successful carbon sequestration may be, as current models used to evaluate agronomic management oversimplify soil microbial properties. This project will test for the key pathways of carbon transformations using soil samples taken under cover crops from a long-term study site. The team will quantify the chemical diversity of carbon substrates that microbes in the soil take up, and use data mining to predict the impacts of that diversity on soil carbon sequestration and nutrient cycling. The research outcomes will also lay a foundation for future collaborative research within the Department of Energy scientific community, and the soil health research community more broadly.

Bringing confidence to carbon markets through improved monitoring

Lead: Seth Gorelik
Collaborator: Wayne Walker

The protection, improved management, and restoration of forests are key nature-based solutions to the climate crisis, yet implementation and maintenance of these forest-based solutions requires sustainable and substantial financing. The voluntary carbon market (VCM) has the potential to deliver the necessary level of financing; however, a significant gap exists between its potential and actual performance. Improving the accuracy of forest carbon monitoring is crucial for the VCM to deliver effective, meaningful climate change mitigation. This project will enhance the credibility and effectiveness of forest carbon markets by evaluating new remote sensing methods for measuring forest carbon and showing that these methods provide more robust data than the conventional approach. Research findings could lead to updated global standards and policies for issuing carbon credits, which would increase market confidence and promote sustainable forest management.

Applying machine learning models to link river hydrology and fire risk forecasting in the Amazon

Lead: Andrea D. de Almeida Castanho
Collaborators: Michael Coe, Marcia Macedo

In recent decades, extreme drought events have increased forest flammability, fire severity, and the likelihood of fire escaping and spreading into adjacent forests and working lands, as illustrated by the wildfires seen throughout Amazonia during the 2023-24 drought. The project team will explore the potential of using river stage (water level) data as a proxy for landscape dryness, to ultimately reveal the short-term risk of wildfires spreading into forests. If confirmed, this innovative hypothesis could provide the scientific basis for developing new metrics of river stage to improve early-warning systems that forecast high fire risk days to weeks in advance. These improvements would create benefits not only for tropical forest protection, but also for biodiversity, greenhouse gas emissions, and human health.

Extreme heat is wilting and burning forests, making it harder to curb climate change

High temperatures, droughts and wildfire last year caused some forests to wilt and burn enough to degrade the ability of the land to lock away carbon dioxide.

Earth’s land lost much of their ability to absorb the carbon dioxide humans pumped into the air last year, according to a new study that is causing concern among climate scientists that a crucial damper on climate change underwent an unprecedented deterioration.

Temperatures in 2023 were so high — and the droughts and wildfires that came with them were so severe — that forests in various parts of the world wilted and burned enough to have degraded the ability of the land to lock away carbon dioxide and act as a check on global warming, the study said.

The Center for Climate and Security (CCS) is joined by Dr. Christopher Schwalm, Senior Scientist and Risk Program Director at the Woodwell Climate Research Center, to discuss key topics in climate change and security. In this episode, Dr. Schwalm covers climate science and its relation to climate security policymaking.

Amazingly, forests are still sucking up as much carbon as they were 30 years ago. But there’s a catch.

Besieged by logging, fires, and pests, this global balancing act might not last long.

Each year, burning fossil fuels puffs tens of billions of metric tons of planet-warming carbon dioxide into the atmosphere. And for decades, the Earth’s forests, along with its oceans and soil, have sucked roughly a third back in, creating a vacuum known as the land carbon sink. But as deforestation and wildfires ravage the world’s forests, scientists have begun to worry that this crucial balancing act may be in jeopardy.

A study published in the journal Nature on Wednesday found that, despite plenty of turmoil, the world’s forests have continued to absorb a steady amount of carbon for the last three decades.

With the Paris Olympics less than two weeks away, a question hangs over the Games: Will the Seine River be clean enough for athletes to swim in?

Triathlon and marathon swimming are scheduled to take place in the Seine, where it has been illegal to swim for more than a century. Despite the city’s efforts to clean up the long-polluted river, the water has tested unsafe for humans in recent weeks, and cleaner on other days. The Games run from July 26-Aug. 11.

To clean up the river, Paris invested 1.4 billion euros ($1.5 billion) in building infrastructure to catch more stormwater when it rains — the same water that contains bacteria-laden wastewater that enters the river during periods of heavy rain and makes it unsafe to swim in.
