Global Temperatures And Atmospheric CO2: Hottest March Ever; CO2 At All-Time High
NOAA published its report on global land and sea temperatures for March on Friday, April 17. Inasmuch as five of the previous seven months set new records, it was not surprising that March’s land and sea temperatures were the highest ever recorded for that month.
The three months of January through March, and the most recent calendar year are also the warmest ever recorded for those periods of time.
Separately, but not coincidentally, the instruments on Mount Mauna Loa in Hawaii found atmospheric CO2 concentrations to be above 404 parts per billion for the first time on April 14. That was the first of four consecutive days above 400.
