Global warming of the Earth's surface has decelerated (Viewpoint)

2014-06-21

[WaPo]The recently-released National Climate Assessment (NCA) from the U.S. government offers considerable cause for concern for climate calamity, but downplays the decelerating trend in global surface temperature in the 2000s, which I document here.

Many climate scientists are currently working to figure out what is causing the slowdown, because if it continues, it would call into question the legitimacy of many climate model projections (and inversely offer some good news for our planet).
17+ years of no global warming. A WaPo editor published this? The sky is failing! (Because cold air sinks)

Not editor-published -- this is one of their bloggers, a meteorologist with an MBA who at first glance appears to be in the consulting business.

#9 Thanks KBK.

#8 It's not just urban island. They are moving the stations closer to buildings because they are 110V powered, instead of walking to them to take a reading. Also, they have been systematically eliminating remote (colder) stations because they are harder to service and therefore more expensive.

#7 Exactly has Squinty says, and Mr. Watts is a national treasure. What we need are more data points, but even then, you gotta have measurement devices to monitor the micro-climate of airfields. More and more and scattered all over the place. I'll put one on the roof if you want.

#6 But we don't need to be collecting data to support global warming from stations that are close to places that are going to generate lots of heat.

Agreed. Anthony Watts has documented errors in the land-based weather station based temperature measurements. Urbanization has grown and so has urban heating. Weather stations next to blacktop will show higher temperatures.

Best to use satellite data, e.g. UAH Satellite-Based Temperature of the global Lower Atmosphere

#5 I hadn't made the connection before! :-)

But we don't need to be collecting data to support global warming from stations that are close to places that are going to generate lots of heat. Perhaps the apparent global warming is going away because airplane travel is declining and those weather stations aren't getting hit as hard as originally planned?

#4 Gorbachev ? Sorry gorb, thanks for nothing apple.

#3 Gorbachev the stations have traditionally been at airfields because pilots have a very keen interest in local conditions near runways.

#2 I like the idea that convection currents under the crust warm the surface from time to time, much like the bubbles in a lava lamp, I suppose. Then you have sunspots and the fact that "scientists"have been strategically placing measuring equipment next to runways and other places that are subject to localized sources of heat. It's just a matter of time before it unravels. And politicians deciding that it's not a good excuse for a new type of taxation.

#1 It is on the WaPo domain. I suspect that his head is about to be shaped.
