How hot is it? It depends, of course, on where you are. From a global perspective there are agencies that check and recheck and average it all out.
The world’s combined global land and ocean surface temperature made last month the warmest March on record, according to National Oceanic and Atmospheric Administration (NOAA). Taken separately, average ocean temperatures were the warmest for any March and the global land surface was the fourth warmest for any March on record. Additionally, the planet has seen the fourth warmest January – March period on record.
