On December 1, the House Science Committee -- chaired by climate science-denying “bully” Rep. Lamar Smith (R-TX) -- tweeted out a Breitbart.com article promoting false claims about climate science and castigating “climate alarmists”:

.@BreitbartNews: Global Temperatures Plunge. Icy Silence from Climate Alarmists https://t.co/uLUPW4o93V

The Breitbart article was written by James Delingpole, who has previously disparaged climate scientists at NASA, NOAA, and other respected institutions as “talentless low-lives who cannot be trusted." In the article, Delingpole claimed: “Global land temperatures have plummeted by one degree Celsius since the middle of this year – the biggest and steepest fall on record. But the news has been greeted with an eerie silence by the world’s alarmist community.”

As purported evidence, Delingpole cited an article by David Rose in the British tabloid Daily Mail. But Rose’s article is based on egregious cherry-picking, as climate blogger Tamino explains:

[Rose] wants you to think that the worldwide heating we’ve seen for decades now has somehow, magically, come to an end … that it has shown some kind of “pause.” To give that impression, he had to search far and wide for one set of data from which he can cherry-pick one span of time in which he can focus on one recent event, so he can blame this year’s record-breaking heat on something other than mankind and our greenhouse-gas emissions. Thanks to the many many organizations that publish climate data, there are lots and lots and lots of data sets to choose from … so it’s no surprise he found one.

[...]

It’s global average temperature, not for Earth’s surface where we live, but for the lower layer of the atmosphere … not for the whole world, but for the land areas only … and it’s not all the data, it leaves out the part David Rose doesn’t want you to see.

[...]

Data like this, in fact almost all data, are a combination of trend — the long-term pattern that actually has some persistence — and fluctuation — the short-term ups and downs that are only temporary. And there are fluctuations. Plenty. They go up and down and down and up, but never really get anywhere.

It’s abundantly obvious, resoundingly unambiguous, completely clear, and pretty simple, that when it comes to climate what matters is the trend, not the fluctuations. For climate deniers, what’s abundantly obvious, resoundingly unambiguous, and completely clear is what they want to avoid. Because it’s so simple, they have to bend over backwards to distract you from it. Like David Rose did.

Breitbart has a long track record of blatant climate science misinformation, and is even considered a go-to outlet for academics who are bought off by the fossil fuel industry. So the decision by the Republican-led House Science Committee to approvingly cite Breitbart on climate change is ill-advised, to put it mildly. Indeed, it prompted a quick response from Democratic committee member Mark Takano (D-CA), who tweeted: “If Republicans on the House Science Committee are getting their science news from Breitbart, that would explain a great deal.”

Republican committee chairman Lamar Smith, a climate science denier who has taken over $770,000 in career campaign contributions from the oil and gas and electric utility industries, has a track record of harassing and falsely attacking climate scientists -- just like Breitbart does. So it should come as no surprise that Smith has written his fair share of op-eds for Breitbart.
