Researchers from the University of Colorado, Boulder, recently published a paper in the journal Geophysical Researcher Letters demonstrating that average summer temperatures in the Canadian Arctic are the highest in at least 44,000 years, and perhaps in as long as 120,000 years.
"This study really says the warming we are seeing is outside any kind of known natural variability, and it has to be due to increased greenhouse gases in the atmosphere," lead researcher Gifford Miller wrote.
While the science behind climate change may still be controversial in some circles, as the country reflects one year after Hurricane Sandy, it's come increasingly difficult to deny that the planet is growing warmer. And while scientists are notoriously cautious when it comes to cause and effect, most experts agree that there is a link between climate change and devastating storms like Sandy.
Science Friday's Ira Flatow examines the lessons learned, and the link between climate change and extreme weather.
