In global warming news, Arctic Sea ice has melted faster this year than ever before in recorded history. Research from the National Snow and Ice Data Center shows the extent of sea ice earlier this month was hundreds of thousands of square miles less than it was on the same day in 2007, and about 12,000 square miles less than the previous record low in 2010. Researchers say the ice has been melting at more than double the climatological rate and have attributed the increased melting to climate change. The news comes amid a spate of extreme weather in the United States, with wildfires tearing through Colorado and record rainfall in Florida.
