About that “increased moisture” due to global warming …
The latest “proof”offered by the alarmists such as Al Gore to explain how all the snow this year is a result of global warming is to claim global warming causes there to be moisture in the air. Thus, sayeth the Goracle, more rain and snow should be expected.
The first thing that struck me without looking at any science is, if it was warmer and there was more moisture in the air causing more precipitation, wouldn’t that precipitation be in the form of rain? I mean, if it’s really warmer and all. As it turns out though, Gore and the alarmists are flatly wrong. Apparently there’s actually less moisture in the air right now than in previous decades:
According to “State of the Climate” from the National Oceanic and Atmospheric Administration, “Global precipitation in 2009 was near the 1961-1990 average.” And there was certainly no pattern of increasing rain and snow on America’s East Coast during the post-1976 years, when NOAA says the globe began to heat up.
In late January, Scientific American reported: “A mysterious drop in water vapor in the lower stratosphere might be slowing climate change,” and noted that “an apparent increase in water vapor in this region in the 1980s and 1990s exacerbated global warming.”
The new study came from a group of scientists, mainly from the NOAA lab in Boulder. The scientists found: “Stratospheric water-vapor concentrations decreased by about 10 percent after the year 2000 . . . This acted to slow the rate of increase in global surface temperature over 2000 to 2009 by about 25 percent.”
Specifically, the study found that water vapor rising from the tropics has been reduced, because it has gotten cooler there (another inconvenient truth). A Wall Street Journal headline summed it up: “Slowdown in Warming Linked to Water Vapor.”
Moisture in the lower stratosphere (about 8 miles above the earth’s surface) has been going down, not up.
So obviously the Gore/alarmist claim that all of this heavy snow fall can be explained by the global warming theory – er, assertion – is so much nonsense. Not that anyone should be surprised.
It appears now they’re reduced to just making unsubstantiated claims in an effort to salvage the momentum and credibility they’ve rapidly lost since the inception of climategate. This bit of deception is just another nail in the AGW alarmist coffin.
