But about that...
Oh, those wacky professional climate change deniers! Once again, theyâve banded together a passel of people, 90 percent of whom arenât even climatologists, and had them sign a nearly fact-free opinion piece in the Financial Post, claiming global warming isnât real. Itâs an astonishing example of nonsense so ridiculous I would run out of synonyms for âbilgeâ before adequately describing it
The Op-Ed is directed to U.N. Secretary General Ban Ki-Moon, who has recently, and thankfully, been vocal about the looming environmental catastrophe of global warming. The deniersâ letter takes him to task for this, but doesnât come within a glancing blow of reality.
The letter itself is based on a single claim. So letâs be clear: If that claim is wrong, so is the rest of the letter.
Guess what? That claim is wrong. So blatantly wrong, in fact, itâs hard to imagine anyone could write it with a straight face. It says:
âThe U.K. Met Office recently released data showing that there has been no statistically significant global warming for almost 16 years.â
This is simply, completely, and utterly false. The Met Office is the national weather service for the United Kingdom. In October 2012, they updated their database of global surface temperature measurements, a compendium of temperatures taken over time by weather stations around the planet. David Rose, a climate change denier who can charitably be said to have trouble with facts, cherry-picked this dataset and published a horrendously misleading graph in that bastion of scientific thought, the Daily Mail, saying the measurements show thereâs been no global warming for the past 16 years.
But he did this by choosing a starting point on his graph that gave the result he wanted, a graph that looks like thereâs been no warming since 1997. But if you show the data properly, you see there has been warming:
The top graph is from Rose's article, but the bottom graph shows what happens when you display the data going back a few more years. See the difference? What he did is like measuring how tall you are when you're 25, doing it again when you're 30, then claiming human beings never grow. That's a big no-no in science.
You have to choose starting and ending points that fairly represent the data, as in the bottom graph. When you do, you very clearly see the trend that the Earth is getting warmer. In fact, hammering home how patently ridiculous this claims is, nine of the 10 hottest years on record have been since 2000. On top of that, Rose was using global surface temperatures, which donâÂÂt really represent global overall heat content well; most of the heating is going into ocean waters. So the data heâÂÂs displaying so awfully isnâÂÂt even the right data to make his claim anyway!
So the very first basis of this denial letter is total garbage, and was such an egregious manipulation of the U.K. Met Office data that the Met Office itself issued a debunking of it! Yet here were are, months later, with the deniers still ignoring facts.
The letter is chock full of more such falsehoods. If you want the rundown, please go read the great article on Skeptical Science destroying this nonsense. Full disclosure: I had already written quite a bit more for this post before seeing the one at Skeptical Science, and decided it would be better to send readers there for more rather than debunk all the wrongness here. IâÂÂm pleased to note they found the same examples of misleading or outright false statements in the deniersâÂÂ article and debunked them the same way I had.
I do want to add something, though. IâÂÂll note that it seems superficially impressive that they got 125 scientists, âÂÂqualified in climate-related mattersâÂÂ as they claim, to sign this letter.
