climate change

Human activities now account for two-thirds of all methane venting to the atmosphere, and our efforts to staunch the flow are not yet bearing fruit.

In September, a strange nine-day signal rocked our planet and baffled scientists. Now they have finally found the cause.

Volcanoes spewing carbon dioxide 250 million years ago heated the climate so much that extreme El Niño events became the norm, pushing most life on Earth past its limits.

If Atlantic Ocean currents collapse due to melting ice sheets, researchers predict there will be huge shifts in tropical monsoon systems — and the effects could be irreversible for at least 100 years.

Antarctica is covered by a miles-thick ice sheet, but was that always the case? And when was the coldest continent ice-free?

For the first time, researchers have linked the amount of silver being buried in marine sediments to human-made climate change.

Over the past 41,000 years, viral communities have varied significantly between cold and warm climatic periods, scientists found.

Creatures that existed billions of years before plants and animals poised to become dangerous climate change winners.

The carbonate compensation depth — a zone where high pressure and low temperature creates conditions so acidic it dissolves shell and skeleton — could make up half of the global ocean by the end of the century.
