A year-round, ice-free Arctic Ocean could help to explain why the Earth is known to have been significantly warmer during the Pliocene Epoch than the concentration of greenhouse gases in the atmosphere at the time would have otherwise suggested, according to new research from the University of Colorado Boulder. The last time that CO2 levels
The future of the Arctic is now almost set in stone now — warmer, wetter, ice-free, and greener. The last time that CO2 levels were this high, the Arctic temperatures stabilized at temperatures quite a bit warmer than they are now, according to new research done by an international team of researchers led by the
In the last few decades, shrubs in the Arctic tundra have transformed themselves into trees as a result of the warming Arctic climate, at a speed and magnitude that is far greater than scientists had ever anticipated. If this continues and is replicated across the whole of the Arctic tundra, it would significantly accelerate global

According to the authors of the annual Arctic Report Card, temperatures were more than 9 degrees Fahrenheit above normal and are predicted to remain nearly as high this year. “The year 2007 was the warmest year on record in
