Greenland

Greenland’s growing ice slabs intensify meltwater runoff

Sept. 18, 2019

Thick, impenetrable ice slabs are expanding rapidly on the interior of Greenland's ice sheet, sending meltwater spilling into the ocean.

A plume of smoke rising into the air

Wildfire smoke provides clues on nuclear war, geoengineering

Aug. 8, 2019

Wildfire smoke can persist for months in the stratosphere, giving scientists an opportunity to fine-tune models of climate change, nuclear winter and geoengineering.

How sweat leaves your skin and builds up on your wall

May 3, 2019

A CIRES study reveals the fate of indoor chemical emissions, including the unexpected buildup of lactic acid from human sweat.

Boulder flatirons

Untangling methane emissions

March 22, 2019

Using cutting-edge instrumentation, CIRES researchers are able to track and differentiate sources of methane, a greenhouse gas and air pollutant.

Ice shelf breakup

Ice shelves buckle under weight of meltwater lakes

Feb. 13, 2019

CIRES scientists have directly observed an Antarctic ice shelf bending under the weight of ponding meltwater on top, a phenomenon that may have triggered the 2002 collapse of the Larsen B ice shelf.

Greenland

Greenland ice melting faster than expected

Jan. 22, 2019

Greenland is melting faster than scientists previously thought—and will likely lead to faster sea level rise—thanks to the continued, accelerating warming of the Earth’s atmosphere.

Lake Dillon

Colorado’s Lake Dillon is warming rapidly

Jan. 7, 2019

CIRES researchers harnessed 35 years of data to uncover responses of a high-elevation reservoir to a warming world.

Antarctica

A record-low start to the new year in Antarctica

Jan. 3, 2019

The rate of Antarctic ice extent loss for December 2018 is the fastest in the satellite record, according to the National Snow and Ice Data Center.
