NASA: September Was Warmest on Global Record

1 minute read

This September was the warmest on record since 1880–the year scientists first began to track global data on temperatures.

The National Aeronautics and Space Administration’s announcement clips on the heels of what was also the warmest August on record, which NASA said suggests an unfortunate trend in global heating.

The National Oceanic and Atmospheric Administration anticipates that an El Niño will start by the end of the year, due to warmer temperatures in the Pacific Ocean, and continue into spring 2015. An El Niño can have devastating impact across the globe, with repercussions that include abnormal temperatures and extreme weather. The last strong El Niño occurred in 1997-98.
