New research shows storms in the Southern Ocean are producing more rainfall, revealing a major shift in one of Earth’s most important climate systems. Macquarie Island sits in the remote Southern ...

Global scientists warn that humanity is on the verge of crossing irreversible climate thresholds, with coral reefs already at their tipping point and polar ice sheets possibly beyond recovery. The ...

Global temperatures are now widely expected to temporarily exceed the Paris Agreement’s 1.5 °C warming limit, even under the most aggressive emissions-reduction scenarios. That prospect, known as ...

Have you ever stopped to wonder how forecasters can predict the weather days in advance, or how scientists figure out how the ...

Tim Palmer is an emeritus professor of climate science at the University of Oxford, UK, and author of The Primacy of Doubt (2022). What does the science say: hoax, lukewarm inconvenience or ...

The International Court of Justice (ICJ) will issue a highly anticipated advisory opinion overnight to clarify state obligations related to climate change. It will answer two urgent questions: what ...

This is the worst-ever year for climate politics—but the struggle is far from over. Protesters stage a “die-in” during a rally for Climate Justice in Seoul on September 27, 2025. “We are hurtling ...

Climate scientists are confronting a hard truth: some of the most widely used models are struggling to keep up with the pace and texture of real‑world warming. The physics at their core remains sound, ...

Scientists have uncovered a missing feedback in Earth’s carbon cycle that could cause global warming to overshoot into an ice age. As the planet warms, nutrient-rich runoff fuels plankton blooms that ...

If you think of Earth’s climate system as a backyard swing that’s been gently swaying for millennia, then human-caused global warming is like a sudden shove strong enough to disrupt the usual arc and ...

The Earth’s atmosphere is nothing but freely roaming molecules. Left alone, they would drift and collide, and eventually even out into a mixture that’s dynamic, yet stable and broadly unchanging. The ...

Earth system models (ESMs) integrate the interactions of atmosphere, ocean, land, ice, and biosphere to estimate the state of regional and global climate under a wide variety of conditions. A model ...
