A new estimate of Africa’s greenhouse gas budget from 2010 to 2019 shows increasing emissions from cropland expansion, livestock, and fossil fuel use—meaning the continent may have transitioned from an overall carbon sink to a slight carbon source.

Sea Otters’ Appetite for Crab Is Helping Strengthen Estuary Banks
Apex predators can have a powerful impact on coastal erosion rates by keeping grazer populations down, but their influence has been largely overlooked.
Researchers Develop Mexico’s First Comprehensive Greenhouse Gas Budget
A new study delves into 2 decades of data to create a comprehensive quantification of carbon, methane, and nitrous oxide sources and sinks that could help guide climate policy.
Protecting Power Grids from Space Weather
A new paper explores ways to mitigate the impact of geomagnetically induced currents on the New Zealand power grid.
To Meet Climate Goals, Protect the Tongass and Chugach Forests
The two largest U.S. national forests, both in Alaska, have low wildfire risk and provide crucial forest carbon stocks and biodiversity benefits.
Los primeros eventos de deslizamiento lento observados en el sur de Costa Rica
Cinco eventos observados en la Península de Osa revelan nueva información sobre el papel que estos pequeños y lentos terremotos pueden desempeñar en la acumulación de tensión y riesgos de tsunami a lo largo de las zonas de subducción.
The First Slow-Slip Events Seen off Southern Costa Rica
Five events observed off the Osa Peninsula shed new light on the role that these small, slow earthquakes can play in strain accumulation and tsunami hazards along subduction zones.
Mars Has Far Fewer Minerals Than Earth Does
The development of plate tectonics and life on Earth provided avenues for mineral evolution that did not occur on Mars, resulting in relatively limited mineral diversity on the Red Planet.
El cambio climático está secando a los suelos
Los suelos terrestres se están secando a medida que el planeta se calienta, pero aún no está claro que tan seco es muy seco.
Current Agriculture Adds More Phosphorus to Streams Than to Lakes
Improved agricultural nutrient management could improve stream water quality by reducing phosphorus levels, but rising temperatures and rainfall due to climate change might offset improvements.
