Almost 1400 comments on the WSJ. The climate deniers really come out on the WSJ.

Here's some of the article:

"Thirty years of data have been collected since Mr. Hansen outlined his scenarios—enough to determine which was closest to reality. And the winner is Scenario C. Global surface temperature has not increased significantly since 2000, discounting the larger-than-usual El Niño of 2015-16. Assessed by Mr. Hansen’s model, surface temperatures are behaving as if we had capped 18 years ago the carbon-dioxide emissions responsible for the enhanced greenhouse effect. But we didn’t. And it isn’t just Mr. Hansen who got it wrong. Models devised by the United Nations Intergovernmental Panel on Climate Change have, on average, predicted about twice as much warming as has been observed since global satellite temperature monitoring began 40 years ago."

Which is strange considering this article was in the comments:

According to the data it's reporting from NOAA, scenario B has occurred (one degree of warming). El Niño seems to have little to do with it as well, as the warming is concentrated away from it (North America and Europe).
