This time of the year, sea ice in the Arctic is on the rise as winter sets in. A combination of unusually high air temperatures and a warmer than normal ocean led to a record low for Arctic sea ice extent in November. In the Southern Hemisphere, Antarctic sea ice extent also hit a record low for the month.
NASA data show that the Earth’s temperature in July was the highest recorded since record-keeping began 136 years ago. It was also the 10th straight month of record-breaking temperatures and was .18 degrees Fahrenheit higher than the previous hottest July in 2011.
