The watermelon's inconvenient lie

Mark Landsbaum: Climate alarmists' search for proof going cold

Even China’s coal-burning is offered to explain lack of global warming
By MARK LANDSBAUM / Register columnist
Recall global warming hysteria’s halcyon days? Just 13 years ago, Dr. David Viner, senior scientist at Britain’s University of East Anglia’s climatic research unit, confidently predicted that, within a few years, winter snowfall will become “a very rare and exciting event.”
“Children just aren’t going to know what snow is,” he said.

Of course, that doesn’t mesh with what happened. This past October, the UK Express headlined, “Worst winter for decades: Record-breaking snow predicted for November.”
By the end of November, Brits were shivering, “as Britain faces snow, ice and plummeting temperatures,” reported the Mirror newspaper. “Most of Scotland has been issued severe weather warnings for ice, and temperatures are expected to remain low, causing problems with snow and ice across the country.” Winter yet lay ahead.
We shouldn’t pick on Great Britain. There is plenty of global warming foolishness here at home. Recall James Hansen, global warming guru whose alarmist campaign was underwritten by his NASA paycheck. By the 2020s, Hansen predicted in 1986, the U.S. average annual temperature would rise 9 degrees Fahrenheit, or more, and up to 3 degrees by the 2010s.
A funny thing happened on the way to the 2010s and 2020s. It didn’t get so hot. In fact, depending on which data set you use, it probably has cooled down for 17 years.
A recent explanation for this pause (if not reversal), was offered in a scientific paper blaming the El Niño Pacific Ocean warming in 1997-98 for triggering the hiatus.
As the theory goes, El Niño caused a large heat transfer from deep in the ocean to the surface, which cooled the waters below. Since then, according to the theory, heat has been reabsorbed from the upper ocean, in turn cooling the atmosphere. Maybe. Maybe not.
There’s no shortage of inventive excuses for why things aren’t so hot, including, incredibly, China’s increased use of coal, even though “dirty” fossil fuel is supposed to increase, not decrease temperatures.
Implicit in this “where-did-the-heat-go” shell game is an inconvenient reality.
Climatologist Roger Pielke Sr., University of Colorado, Boulder, professor emeritus of Atmospheric Science, says, if correct, the ocean paper means, “the end of surface temperature trends as the icon of global warming.”
If so, that’s a game changer for the climate wars.
If surface temperatures lose their credibility (and we side with those who long have said that’s the case), where will alarmists point to prove their point?
There always have been problems relying on land-based thermometers. For instance, where should thermometers be placed? How high off the ground? There are no worldwide uniform standards.
While airports, concrete and asphalt represent a scant percentage of Earth’s surface, they are home to a disproportionate percentage of ground measuring stations. Does this matter? Consider the common sense knowledge that standing in a grassy field is cooler than standing on an asphalt runway. Not only are such locales hotter, they get hotter faster and hold their temperatures disproportionately longer.

Then consider that the preponderance of ground stations are located in developed countries, and a vastly disproportionate number of those are in the United States. Is Los Angeles a reasonable proxy for Peruvian farmland or the steppes of Russia?
Arguments against specious temperature measurements are too numerous to list here. But consider this: Two separate satellite temperature data sets agree that whatever warming may have occurred peaked in 1998, and stopped around 2000. Ground-temperature records say 2006 or 2010 were hotter, and that the warming trend continues.
Worse yet, temperatures used by warming advocates collected from land-based thermometers are continually “adjusted.” They don’t remeasure the temperature. They change it. As Australian climate watchers David Evans and Jo Nova point out, “they are still changing the temperature record for the 1970s, 30 years later, and always in the direction of making recent warming seem worse.”
We are told to trust people, who never seem to adjust questionable raw data to lessen the alleged threat.
It’s a tragedy that we can’t trust the science because of agenda-driven scientists. But it is more than an academic exercise. Global warming alarmists’ temperature claims have driven political agendas across the world for decades.
The latest stampede to combat dreaded global warming says $100 billion a year must be paid by nations with more money to nations with less. If you are suspicious that this is more of a wealth redistribution than a climate-cooling maneuver, congratulations. It is.
Meanwhile, U.S. government bodies, forever searching for revenue to feed their appetites, are imposing costly taxes to save us from nonthreatening global warming, while conveniently expanding their control. That’s why President Barack Obama had no qualms in claiming that we have had 10 years of “accelerated global warming,” even in the face of contradictory facts. Hold on to your wallets.
