Cloud Feedbacks in CMIP6 Models Versus Expert Synthesis
Models with smallest feedback errors are found to have moderate cloud feedbacks and equilibrium climate sensitivity of 3 to 4 degrees of warming when the concentration of carbon dioxide is doubled.
Planting Wetlands Could Help Stave Off Climate Catastrophe
A shift in priority and approach to wetland restoration could reduce atmospheric carbon.
Climate Action Plans Tailored to Indian Cities
The plans identify localized vulnerabilities, as well as adaptations to climate change risks.
Less Air Travel May Partially Contribute to Global Warming
Decrease in aircraft soot emission, as shown by COVID-19 lockdown, leads to a significant increase in ice crystal number in cirrus clouds, and results in a small global positive radiative effect.
A Climate Mystery Warns Us to Heed the Unknown
The Curve is a series charting the mysterious rise of methane in our atmosphere and the quest to find its source.
Greenhouse Gases Must Begin to Fall by 2025, Says U.N. Climate Report
Emissions rates are still growing every year, though that growth has slowed. The world needs to reach negative growth soon to prevent a potential 3.2°C rise by the end of the century.
Mortality of Seagrass Meadows May Not Kill Their Methane Release
New research indicates that seagrasses continue to release methane even after they die, complicating blue carbon initiatives.
U.S. Businesses May Be Required to Report Emissions, Climate Risk
The proposed rules seek to give investors more complete and standardized climate risk information. The move would bring U.S. policy closer to international standards.
Inventorying Earth’s Land and Ocean Greenhouse Gases
A new special collection in AGU journals will present findings from the Second REgional Carbon Cycle Assessment and Processes (RECCAP2) study with a decade of data on greenhouse gas growth.
