NOAA global temperature analysis: March 2020 is 2nd warmest March ever recorded

Arctic sea ice extent for March 2020 was 251,000 square miles (4.2 percent) below the 1981–2010 average and the 11th smallest March extent in the 42-year record, according to analysis by the National Snow and Ice Data Center (NSIDC) using data from NOAA and NASA. The Arctic reached its maximum annual extent on March 5 at 5.81 million square miles and was also the 11th smallest annual extent on record. 
Antarctic sea ice extent during March 2020 was 1.54 million square miles, which is near the 1981–2010 average. According to the NSIDC, March 2020 ended Antarctica’s 41-month period of below-average monthly sea ice extent.

In the 1,681 previous months, only three were more above normal. These three months -- March 2016, February 2016 and December 2015 -- occurred with an El Niño present in the tropical Pacific Ocean, which acts to temporarily heat the Earth naturally. 
But this time, we achieved these temperatures all on our own. With no El Niño anomaly present this year, these temperatures are a product of the ever-increasing global temperature rise that scientists attribute to greenhouse gas-induced warming.
