(Skeptical Science) – Human carbon pollution is heating the Earth incredibly fast. On top of that long-term human-caused global warming trend, there are fluctuations caused by various natural factors. One of these is the El Niño/La Niña cycle. The combination of human-caused warming and a strong El Niño event are on the verge of causing an unprecedented three consecutive record-breaking hot years.

Simply put, without global warming we would not be seeing record-breaking heat year after year. In fact, 2014 broke the temperature record without an El Niño assist, and then El Niño helped push 2015 over 2014, and 2016 over 2015.

Sadly, we live in a post-truth world dominated by fake news in which people increasingly seek information that confirms their ideological beliefs, rather than information that’s factually accurate from reliable sources. Because people have become incredibly polarized on the subject of climate change, those with a conservative worldview who prefer maintaining the status quo to the steps we need to take to prevent a climate catastrophe often seek out climate science-denying stories.

Into that environment step conservative columnists David Rose at the Mail on Sunday, parroted by Ross Clark in The Spectator and James Delingpole for Breitbart, all trying to blame the current record-shattering hot global temperatures entirely on El Niño. Perhaps saddest of all, the House Science, Space, and Technology Committee tweeted the Breitbart piece, to which Senator Bernie Sanders appropriately responded: “Where'd you get your PhD? Trump University?”

An über cherry-picked argument

The conservative columnists made their case by claiming that, with the recent strong El Niño event ending, temperatures are “plummeting,” thus blaming the record heat on El Niño. There are several fatal flaws in their case.

First, the “plummet” they cite is not in global temperatures on the surface where we live, and where temperatures are easiest to measure accurately, but rather in satellite estimates of the temperature of the lower atmosphere above the portions of Earth’s surface covered by land masses. Second, although the satellite data extend as far back as 1979, and the global surface temperature data to 1880, they cherry pick the data by only showing the portion since 1997. Third, the argument is based entirely upon one relatively cool month (October 2016) that was only cool in that particularly cherry-picked data set.

The argument is easily debunked. While there was a strong El Niño event in 2015–2016, there was an equally strong event in 1997–1998. The two events had very similar short-term warming influences on global surface temperatures, but according to NASA, 2016 will be about 0.35°C hotter than 1998. That difference is due to the long-term, human-caused global warming trend. In fact, according to NASA, even October 2016 was hotter than every month on record prior to 1998. These “plummeting” post-El Niño temperatures are still as hot as the hottest month at the peak of the 1998 El Niño. [more]

    The reality is that most "news" is fake. The claim that CNN and Fox produce "real" news is laughable. Most reliable information is, and has always been buried in books, that most are too lazy to read.

    The StupidNet has become intolerable for intelligence. Very hard to find good information. Social networking sites have taken over intelligent discussion. Google literally "owns" words and search terms (punishing millions, including businesses). Information freedom has also meant information disaster. Propaganda is passed of as snooze. The serious and significant is relegated to the mundane (interspersed with ads for the scantily clad starz). Facebook cultivates hordes of morons. Infowars does the same. All are subjected to mind-bending propaganda and brainwashing. Books are indeed far, far better. But you have to be able to read. ~Survival Acres~
