Rising Air and Sea Temperatures Continue to Trigger Changes in the Arctic

Rising Air and Sea Temperatures Continue to Trigger Changes in the Arctic

A new NOAA-led report shows that Arctic air temperatures continue to rise at more than twice the rate of global air temperatures, a phenomenon known as Arctic amplification. Increasing air and sea surface temperatures, declining reflectivity at the surface of the Greenland ice sheet, shrinking spring snow cover on land and summer ice on the […]

Warmer Pacific Ocean Could Release Millions of Tons of Seafloor Methane

Warmer Pacific Ocean Could Release Millions of Tons of Seafloor Methane

Off the West Coast of the United States, methane gas is trapped in frozen layers below the seafloor. New research from the University of Washington shows that water at intermediate depths is warming enough to cause these carbon deposits to melt, releasing methane into the sediments and surrounding water. Researchers found that water off the […]

Global Warming not just a Blanket

By Hannah Hickey | University of Washington on Nov 12, 2014   Featured, Science/Education  

While computer models churn out bleak forecasts for the planet’s future, we also have a more conceptual understanding of what is happening as humans pump carbon dioxide into the air. But the conceptual understanding of carbon dioxide wrapping the planet in a blanket that traps more heat is not quite right. A new study from […]

New Study Shows Three Abrupt Pulses of CO2 During Last Deglaciation

New Study Shows Three Abrupt Pulses of CO2 During Last Deglaciation

A new study – led by Oregon State University, with significant contributions from the University of Washington – shows that the increase of atmospheric carbon dioxide that contributed to the end of the last ice age more than 10,000 years ago did not occur gradually but rather was characterized by three abrupt pulses. Scientists are […]
