Most of the warming occurred in the past 35 years, with 15 of the 16 warmest years on record occurring since 2001.
we also note that 2015 easily broke the record set in 2014:
During 2015, the average temperature across global land and ocean surfaces was 1.62°F (0.90°C) above the 20th century average. This was the highest among all 136 years in the 1880–2015 record, surpassing the previous record set last year by 0.29°F (0.16°C) and marking the fourth time a global temperature record has been set this century. This is also the largest margin by which the annual global temperature record has been broken. Ten months had record high temperatures for their respective months during the year. The five highest monthly departures from average for any month on record all occurred during 2015.
After 2014 set the record climate deniers all quickly noted that it was barely above the previous record. I wonder what excuse they’ll use this year to say why this doesn’t show there’s global warming (obviously they’ll use the fact it was a El Nino year, but what else?)?
Note: It’s sad that I know most of the conservatives will continue to deny the existence (or at least the importance) of global warming despite this new data which pretty clearly shows it.
