Siberia’s ice is melting, revealing its past and endangering its future

Sheets of the softening land have emerged for the first time in hundreds of thousands of years, revealing skeletons, disease and awakening life.
sesquiterpenes cloud seeding aerosols

A revelation about trees is messing with climate calculations

Trees make clouds by releasing small quantities of vapors called “sesquiterpenes.” Scientists are learning more—and it’s making climate models hazy.
methane-rich groundwater thawing permafrost

The Arctic is a freezer that’s losing power

As glaciers retreat, methane-rich groundwater is bubbling to the surface. That may be warming the climate, accelerating the Arctic’s rapid decline.
Melting Arctic glaciers releasing methane

Melting Arctic glaciers are triggering the release of methane

Scientists found that rapidly retreating Arctic glaciers are triggering the release of methane, a potent greenhouse gas that causes global temperatures to rise, into the atmosphere.
melting glaciers of Svalbard

The melting glaciers of Svalbard offer an ominous glimpse of more warming to come

New research reveals what one scientist called a “very stark image of climate change” as methane leaks from springs exposed by the glaciers’ retreat.
