For more than a quarter billion years, coral reefs did far more than brighten shallow seas. Long before humans appeared, ...

Earth’s climate is shifting faster than many models anticipated, and scientists now warn that self-reinforcing feedbacks could push key systems beyond their stable range. Instead of a smooth, ...

A pull in the right direction ...

Abrupt climate shifts are well documented in Earth's history and are commonly associated with ice-sheet dynamics during past ice ages. However, how similar millennial-scale climate variability could ...

The Amazon rainforest is so big that it makes its own climate. As they photosynthesise and transpire, its billions of trees collectively produce enough moisture to form clouds. These, by some ...

A new study by UC Davis and Chinese researchers shows how extraterrestrial forces move Earth's climate into a glacial phase both over the last 34 million years and 300 million years. Recent rapid ...

Coral reefs around the globe have for years suffered publicly in warming oceans, periodically making headlines when iconic underwater landscapes lose their colors and wither during repeated mass ...

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 ...

"Without Mars, Earth's orbit would be missing major climate cycles. What would humans and other animals even look like if Mars weren't there?" ...

For decades, global temperature averages have been the yardstick by which we measure our planet's fever. Leaders gather at climate summits, news anchors announce record-breaking years, and scientists ...
