Polar Bears Don't Slow Down in the Summer: Metabolism Risk in a Warmer Arctic

Polar bears may be less resilient to ice melt than previously thought. Scientists have found that while polar bears can reduce their energy expenditure a little, it's not enough to make up for current food shortages.

Climate Change: Arctic Tundra May Cause Large Climate Warming Impact with Shrubs

The changes in the Arctic tundra due to climate change may not just be limited to just that area. It turns out that the alterations could fuel further warming in other areas.

Woolly Mammoth Genome May Allow Scientists to 'Resurrect' Extinct Species

Scientists have conducted the first comprehensive analysis of the woolly mammoth genome and have found extensive genetic changes that allowed mammoths to adapt to life in the arctic.

NASA Satellites Reveal the Arctic is Absorbing More Solar Radiation as Ice Disappears

It turns out that there's been a steady increase in the absorption of solar radiation by the Arctic. Now, NASA satellite instruments are revealing a bit more about this absorption.

NOAA Report Reveals Arctic Temperatures are Rising Twice as Fast as the Rest of Earth

It turns out that the Arctic is getting a bit warmer. A new NOAA-led study reveals that temperatures are rising at more than twice the rate of global air temperatures.

Arctic Peat May Release More Methane Than Previously Thought

As Arctic peatlands warm, they're releasing more and more greenhouse gases. Now, scientists have taken a closer look at these normally-frozen regions and have created more accurate models to predict methane emissions and carbon dioxide emissions.

Melting Arctic Doesn't Mean the Ocean's Gulf Stream Will Halt

It turns out that a melting Arctic is not the reason why Nordic Seas are becoming less saline. Scientists have found that the source of fresher water is actually linked to the Gulf Stream, which is ferrying water from the Atlantic to the Arctic.

Sunlight May be Key to Carbon Dioxide Release from Arctic Permafrost

Scientists have discovered that it's not bacteria triggering the process of Arctic permafrost's carbon being converted to carbon dioxide--but sunlight.

Arctic Lakes May Soak Up Greenhouse Gases as Permafrost Melts

Scientists have found a new natural system that may help combat climate change. It turns out that Arctic thermokarst lakes may help thwart global warming by storing more greenhouse gases than they emit into the atmosphere.
