The End of Global Warming

An important Op-Ed showed up last week, titled "Cooling down with global-warming data."

"We can't know for sure if global warming is a problem if we can't trust the data," said Anthony Watts, veteran broadcast meteorologist, who for three years organized an extensive review of official ground temperature monitoring stations, in conjunction with Dr. Roger Pielke Sr., senior research scientist at the Cooperative Institute for Research in Environmental Sciences and professor emeritus of the Department of Atmospheric Science at the University of Colorado.

The study, recently published by the free-market Heartland Institute, inspected 860 of the 1,221 U.S. ground stations that gauge temperature changes. The findings were alarming.

They found 89 percent of stations "fail to meet the National Weather Service's own siting requirements" that say stations must be located at least 100 feet from artificial heat sources.

What specifically is being addressed is the Surface Stations Project. In particular, look at the overview of the survey map:

What this means is that the vast majority of the actual measuring stations have a bias that shows temperatures warmer than they really are.

Note a good station vs. a bad station.


Take a look at this station in Santa Ana:

That's right, that's a temperature monitoring station on a roof, with AC exhaust all around. How can we even trust the surface data if this is how it's measured?

The Detroit Lakes Station was apparently shamed into fixing their setup. Is it any wonder this setup showed warming over time?

Of course it's not surprising--as those AC vents got added, it would increase the hot air exhaust over time. In fact, the overall warming trend is smaller than the bias from the improper stationing. Which means that we might be in the middle of a global cooling trend.

In fact, AccuWeather suggests we might be in for a year without a summer this year:
According to Long Range Expert Joe Bastardi, areas from the northern Plains into the Northeast will have a “year without a summer.” The jet stream, which is suppressed abnormally south this spring, is also suppressing the number of thunderstorms that can form.
Good thing we're ready to pass that cap-and-trade on carbon! Perfect timing.

Very nicely presented. I've posted extensively on this in the past, most extensively here. The completely unreliable nature of the data finishes undermining any credibility the anthropogenic theory of global warming may have had.
