Uncertainty in climate models could mean Earth systems are perilously close to their tipping points, scientists warn.
Modeling
The AMOC of the Ice Age Was Warmer Than Once Thought
An analysis of sediment cores indicates that North Atlantic waters were relatively warm and continued to circulate even under major climate stress during the Last Glacial Maximum.
From Measurements to Solar Wind Model Initial Conditions
A new method shows how solar wind measurements at Earth can be used to define initial conditions for solar wind models to reduce their need for solar magnetic maps and decrease their uncertainty.
Plastic Debris Helps Oil Residues Reach Farther Across the Ocean
Scientists matched oil residues found in Florida to a Brazilian spill thousands of miles away.
The Past 3 Years Have Been the Three Hottest on Record
Extreme heat in 2023, 2024, and 2025 indicates a warming spike, a new analysis finds.
Temperatures Are Rising, but What About Humidity?
Humid heat extremes are less frequently studied, but no less important, than those of dry heat.
What Could Happen to the Ocean’s Carbon If AMOC Collapses
Mass glacier melting may have led this influential ocean current system to collapse at the end of the last ice age. A pair of modeling studies examines how such a collapse could affect dissolved inorganic carbon and carbon isotopes in Earth’s oceans.
Climate Change Could Drive Butterflies and Plants Apart
Insects and the plants they depend on are migrating in response to climate change, but not always in the same way.
Trump Administration Plans to Break Up NCAR
The Trump administration is planning to dismantle the National Center for Atmospheric Research, one of the world’s leading climate and Earth science research laboratories, according to a statement from Russ Vought, director of the White House Office of Management and Budget, to USA Today.
Climate Modeling for Communities, with Communities
End users, such as Indigenous community members developing climate adaptation efforts, make better use of climate models when researchers collaborate with them from the start.
