A critical tipping point for the Earth’s climate is the potential transformation of the world’s largest tropical forests from carbon sinks into net sources of emissions, which has been challenging for researchers to predict. But now, groundbreaking studies analyzing observations from Amazonian and African tropical forests find these forests have already reached or are nearing their “saturation points.” Halting deforestation and degradation of forests, while cutting global emissions is critical.
Soil scientists disagree about whether soil carbon sequestration can effectively help decarbonize the atmosphere, but this debate does not undermine the substantive body of science supporting immediate, widespread adoption of practices protecting and restoring soil carbon.
The Paris Agreement’s five year anniversary was marked by governments enacting policy to meet their Nationally Determined Contributions, as well as the U.S. announcing it will re-enter the pact. But what exactly does the U.S. stand to gain by rejoining, and what can nations gain from renewed ambition?
Research demonstrates well-designed policies can help biofuels and bioenergy meet niche energy needs sustainably, while alternative technologies mature and deploy at scale.
Scientific studies demonstrate how climate change is shaping wildfire activity in California, but additional research also shows aggressive action to reduce elevated fuel availability may reduce risk.
This research review details financial, racial, and partisan rates of rooftop solar adoption across the United States and recommendations to overcome these divides.
This research review discusses how potential use of negative emission technologies to meet climate change goals could impact land use.
This research review discusses how energy justice can be achieved for communities and ecosystems as part of a clean energy transition.
The United States Energy Policy Simulator 2.0 update includes the ability to model net-zero emissions, new policies, and new fuels like hydrogen.
This research review says direct air capture and storage may help limit global warming to 1.5C but needs technical innovation and regulatory reform.
