Bird excrement may be cooling the Arctic

(Phys.org)—A team of researchers with members from Canada, Sweden and U.S. has found that bird excrement may be playing a role in cooling the Arctic during its warmer months. In their paper published in the journal Nature ...

Cloudy with a chance of warming

Clouds can increase warming in the changing Arctic region more than scientists expected, by delivering an unexpected double-whammy to the climate system, according to a new study by researchers at NOAA, the University of ...

Extreme diving, crucial to Arctic research

How do algae react to the warming of the Arctic Ocean? How is it affecting wildlife in the fjords? To find answers, researchers rely heavily on divers who brave the icy waters to gather samples.

Heat release from stagnant deep sea helped end last Ice Age

The build-up and subsequent release of warm, stagnant water from the deep Arctic Ocean and Nordic Seas played a role in ending the last Ice Age within the Arctic region, according to new research led by a UCL scientist.

Whitening the Arctic Ocean: May restore sea ice, but not climate

Some scientists have suggested that global warming could melt frozen ground in the Arctic, releasing vast amounts of the potent greenhouse gas methane into the atmosphere, greatly amplifying global warming. It has been proposed ...

Storing carbon in the Arctic

For the past three decades, as the climate has warmed, the massive plates of sea ice in the Arctic Ocean have shrunk: In 2007, scientists observed nearly 50 percent less summer ice than had been seen in 1980.

Weather extremes provoked by trapping of giant waves in atmosphere

The world has suffered from severe regional weather extremes in recent years, such as the heat wave in the United States in 2011 or the one in Russia 2010 coinciding with the unprecedented Pakistan flood. Behind these devastating ...
