Until recently, scientists debated whether Antarctica was warming.
But a January study in the journal Nature found that Antarctica's average annual temperature has increased by about 1 degree Fahrenheit since 1957, but is still 50 degrees below zero.
The report also determined that autumn temperatures in east Antarctica were cooling over the long term. International Polar Year researchers found that the southern ocean around Antarctica has warmed about 0.36 degrees Fahrenheit in the past decade, double the average warming of the rest of the Earth's oceans over the past 30 years.
