This report continues the trend we have been seeing all year. See my previous postings on the state of the climate for June and July.
This is really grim. But, you know what the worst part is? Deniers will point at last weekend's cold snap and say that there is no global warming.
Let's update the tally for the year:
August was the hottest August ever recorded;
July was the fourth hottest July ever recorded;
June 2014 was the hottest June ever recorded;
May was the hottest May ever recorded;
April tied 2010 as the hottest April ever recorded;
March was the fourth hottest March ever recorded;
We got a break in February. It was only the 21st hottest February ever recorded;
But, that break followed the hottest January since 2007 and the fourth hottest January on record.
So, let's see what the score is so far for 2014: one 21st hottest month, three 4th hottest months, and four hottest months ever.
And, overall, 2014 is on track to be the third hottest year ever recorded.
But, the deniers will continue to claim the warming has stopped. That only works to make bad news even worse.
