Santa’s workshop not flooded – but lots of melting in the Arctic

pool of water

Widespread media reports of a lake at the North Pole don’t hold water — but scientists who deployed the monitoring buoys are watching closely as Arctic sea ice approaches its yearly minimum.

Clearing up confusion on future of Colorado River flows

Lake Powell and dam

Leading experts on water issues in the Western U.S. have come together to establish what is known about the future of Colorado River water, and to understand the wide range of estimates for future flows.

Pollution in Northern Hemisphere helped cause 1980s African drought

smokestacks

Air pollution in the Northern Hemisphere in the mid-20th century cooled the upper half of the planet and pushed rain bands south, contributing to the prolonged and worsening drought in Africa’s Sahel region. Clean air legislation in the 1980s reversed the trend and the drought lessened.

Amazon River exhales virtually all carbon taken up by rain forest

A study published this week in Nature Geoscience shows that woody plant matter is almost completely digested by bacteria living in the Amazon River, and that this tough stuff plays a major part in fueling the river’s breath.

Recent Antarctic climate, glacier changes at the ‘upper bound’ of normal

A sectionof the West Antarctic Ice Sheet Divide core.

In recent decades the thinning of glaciers at the edge of Antarctica has accelerated, but new UW-led research indicates the changes, though dramatic, cannot be confidently attributed to human-caused global warming.

A volunteer project enlists citizen scientists to transcribe climate observations buried in historic logbooks of U.S. ships that spent time in the Arctic.

Remote clouds responsible for climate models’ glitch in tropical rainfall

One of the most persistent biases in global climate models is due to poor simulation of cloud cover thousands of miles to the south.

The fibrous threads helping mussels stay anchored are more prone to snap when ocean temperatures climb higher than normal.

European satellite confirms UW numbers: Arctic Ocean is on thin ice

Chuchki Sea ice

New satellite observations confirm a University of Washington analysis that for the past three years found accelerated declines in the volume of Arctic sea ice.

Cyclone did not cause 2012 record low for Arctic sea ice

Satellite image of Arctic cyclone

A huge Arctic cyclone in August was not responsible for the historic minimum seen soon after in Arctic sea-ice extent.

International study: Where there’s smoke or smog, there’s climate change

Scientists taking snow samples in Greenland.

A new international assessment found that soot, or black carbon, is a major contributor to global warming — second only to carbon dioxide.

International study provides more solid measure of shrinking in polar ice sheets

Channel through glacier

Climatologists have reconciled their measurements of ice loss in Antarctica and Greenland during the past two decades. A second article looks at how to monitor and understand accelerating losses from the planet’s two largest continental ice sheets.

UW scientists are teaming with the U.S. Coast Guard to study the new frontier in the Arctic Ocean opened up with the melting ice.

Shrinking snow depth on Arctic sea ice threatens ringed seal habitat

Scientists found that the habitat required for ringed seals — animals under consideration for the threatened species list — to rear their young will drastically shrink this century.

Experiment would test cloud geoengineering as way to slow warming

A University of Washington scientist has proposed an experiment to test cloud brightening, a geoengineering concept that alters clouds in an effort to counter global warming.

How do they do it? Predictions are in for Arctic sea ice low point

University of Washington researchers used some new techniques this year in hopes of improving the accuracy of their annual prediction of the low point of Arctic sea ice.
