Analyses by NOAA and NASA showed 2015 to be the hottest year ever recorded. This should come as no surprise to anyone seeing as how ten of the twelve months set records as the hottest ever recorded, including a string of eight in a row. This included a record-shattering December, which was not only the hottest December ever recorded but was 1.11°C (2.00°F) higher than the monthly average. The margin of increase in the record was the largest ever, breaking the previous all-time record set only two months earlier in October 2015 by 0.12°C (0.21°F). This is the first time in the NOAA record that a monthly temperature departure from average exceeded 1°C and the second widest margin by which an all-time monthly global temperature record has been broken. (February 1998 broke the previous record of March 1990 by 0.13°C / 0.23°F.)
You would think this would be enough to cause deniers to shut-up for a while. Unfortunately, that isn't the case. In fact, they are now claiming 2015 wasn't hot at all. And, then they wonder why people look on them with disdain. It's hard to have any respect for someone who promotes such nonsense.
What they are really concerned about is that the heat will continue. In this we can finally agree, but for different reasons. I'm concerned because it will not be good for the planet. They're concerned because they're afraid people will finally see them for the liars and deceivers they are.
