Melissa Omand’s clever tech follows the fate of ocean carbon
Drawn to the water early, oceanographer Melissa Omand now leads research cruises studying how carbon and nutrients move through the seas.

Shrinking sea ice threatens natural highways for caribou, plants
As Arctic sea ice declines, Peary caribou or plants risk getting stranded when their frozen highways thaw.

Arctic sea ice shrinks to second-lowest low on record
A warm summer helped shrink sea ice in the Arctic Ocean to a statistical tie with 2007 for the second smallest sea ice minimum on record.

Wave-thumping ‘weather bomb’ storms send elusive S waves through Earth
A rare type of deep-Earth tremor called an S wave generated by a rapidly strengthening storm could help scientists map the planet’s mantle and core.

Global warming amplified death toll during 2003 European heat wave
Climate change caused hundreds of fatalities in London and Paris during the 2003 European heat wave, simulations suggest.
- Animals
Ways to beat heat have hidden costs for birds
Birds that look as if they’re coping with heat waves and climate change may actually be on a downward slide, with underappreciated disadvantages of panting and seeking shade.

India’s monsoon winds trace back nearly 13 million years
The intense monsoon winds that carry torrential rain to India each year first started blowing around 12.9 million years ago, new research suggests.

Woolly mammoths’ last request: Got water?
Woolly mammoths survived on an Alaskan island thousands of years after mainland mammoths went extinct. But they died out when their lakes dried up, thanks to a warming climate and rising sea levels.

Phytoplankton’s response to climate change has its ups and downs
In a four-year experiment, the shell-building activities of a phytoplankton species underwent surprising ups and downs.

Warming alters mountain plant’s sex ratios
Global warming has different effects on male and female plants. Tracking sex ratio shifts could be a fast signal of climate change, researchers say.

Despite volcanic setback, Antarctic ozone hole healing
The September extent of the Antarctic ozone hole has shrunk by about 4.5 million square kilometers since 2000, thanks in large part to the Montreal Protocol.

World will struggle to keep warming to 2 degrees by 2100
Current plans to curb climate change aren’t ambitious enough to limit global warming below 2 degrees Celsius by 2100, new research shows.
