|On Monday and Tuesday, about 12 percent of the Greenland ice sheet surface area – 656,000 square miles or 1.7 million square kilometers – showed signs of melting ice. It smashed the record for early melting by more than three weeks. Normally, no ice should be melting in Greenland at this time of year. Even in 2012, when 97 percent of Greenland experienced melt, it didn’t have such an early and extensive melt. Stunned scientists said they had to recheck their calculations before releasing the results.|
|February smashed the previous record for the warmest February and even became the warmest month ever compared to average, according to NOAA. February temperatures over land and ocean averaged a scorching 2.18 F/1.21 C above the 20th century average.|
With records going back to 1880, that makes 1,646 months of data, and February tops them all. But what's even more alarming is that the top four months in terms of heat are the past four, going back to December 2015, and they all top 1 C warmer than the 20th century average. Our 'tipping point' may already have been passed.
