"2015 Is Shaping Up to Be the Hottest Year on Record"

"The first three months of 2015 were the warmest start to any year on record, according to new data released from NASA on Wednesday.

All major global temperature-tracking agencies have ranked January, February, and March 2015 as among the warmest three months on record, respectively. Collectively, those numbers mean 2015 has been record hot so far. What’s more, the last 12 months (from April 2014 to March 2015) was the warmest 12-month period on record, according to the NASA data. The previous warmest 12-month period ended just last month, so don’t write this one down in your diary in ink.

The news comes amid increasingly confident forecasts that there will be a strengthening El Niño for the remainder of 2015, which could spark a litany of impacts worldwide, not the least of which is the more efficient transport of heat from the oceans to the atmosphere. That liberated heat from the Pacific Ocean should boost global temperatures to never-before-recorded levels, making 2015 the warmest year ever measured."
