UN Emissions Gap Report: Despite Progress, World Still Far Behind Climate Targets
Current emissions trajectories are on track to warm the world by as much as 2.8°C (5.04°F) above preindustrial levels by 2100, according to a report released today by the United Nations Environment Programme (UNEP).
Fire, Not Deforestation, Is Now the Amazon’s Biggest Carbon Emitter
Forest degradation in the Amazon increased by 400% in 2024. It was largely driven by wildfires during the forest’s worst fire season in more than 20 years.
Atmospheric Rivers Shaped Greenland’s Ancient Ice
New simulations reveal how atmospheric rivers influenced Greenland’s ice sheet during the Last Interglacial—offering clues to future melt in a warming world.
Serendipity in Space: NASA’s Eye in the Sky
The Orbiting Carbon Observatory-2 (OCO-2) mission, proposed for early termination, has turned out to be a boon to forest and agricultural management.
REDD+ Results and Realities
A new study examines the efficacy of REDD+ projects in reducing deforestation and raises questions about the carbon credits the initiative relies on.
Rising Temperature and Decreasing Snow Cover Increase Soil Breakdown
With climate change and rising temperatures, soil freeze-thaw – which is in turn causing soil breakdown – may counterintuitively increase in the hillslopes where snow cover is decreasing.
Global Climate Models Need the Nitrogen Cycle—All of It
Nitrogen plays important roles in areas including climate change, human health, and agriculture. A researcher argues that climate models would benefit from more fully incorporating its influence.
2025 State of the Climate Report: Our Planet’s Vital Signs are Crashing
A yearly analysis of climate change’s progress and effects shows a “planet on the brink” of ecological breakdown and widespread crisis and suggests that only rapid climate mitigation able to avoid the worst consequences.
Developing Nations Need 12 Times More Financing to Meet Climate Adaptation Needs
An annual United Nations report, published 29 October, reveals a “yawning gap” between existing and necessary climate adaptation finance, a gap “putting lives, livelihoods, and entire economies at risk.”
Building Better Weather Networks
A lack of weather data often leaves African communities vulnerable. Convergent efforts to improve observational networks throughout the continent are slowly filling the gaps.
