Chart of the Week: 2015 Was Earth's Hottest Year on Record
Since 2001, our planet has experienced 15 out of the 16 hottest years on record. Now, we know that 2015 was Earth's warmest year ever recorded.
According to the NOAA, during 2015, the globally-averaged land surface temperature was 2.39°F (1.33°C) above the 20th century average. This was the highest among all years in the 1880–2015 record, surpassing the previous record of 2007 by 0.45°F (0.25°C). This is the largest margin by which the annual global land temperature has been broken.
As President Obama said in his final State of the Union address, if you want to debate the science of climate change, feel free to do so–but you'll be pretty lonely. America's business leaders, the Pentagon, the majority of the American people, the scientific community, and nations around the world already know that now is the time to act.
"It is a key data point that should make policy makers stand up and take notice–now is the time to act on climate."
NASA Administrator Charles Bolden
