The Day After Yesterday
For at least a decade, now, it seemed as if whatever was happening on the planet, globally, regionally, whatever, was attributed to climate change. Here’s more indication that even things that weren’t happening on the planet were being thus attributed:
More trouble looms for the IPCC. The body may need to revise statements made in its Fourth Assessment Report on hurricanes and global warming. A statistical analysis of the raw data shows that the claims that global hurricane activity has increased cannot be supported. …
Hatton performed a z-test statistical analysis of the period 1999-2009 against 1946-2009 to test the six conclusions. He also ran the data ending with what the IPCC had available in 2007. He found that North Atlantic hurricane activity increased significantly, but the increase was counterbalanced by diminished activity in the East Pacific, where hurricane-strength storms are 50 per cent more prevalent. The West Pacific showed no significant change. Overall, the declines balance the increases.
“When you average the number of storms and their strength, it almost exactly balances.” This isn’t indicative of an increase in atmospheric energy manifesting itself in storms.
And while I’m on the topic of the collapse of the global warming hysteria, here’s some more commentary on the matter of global temperatures:
In all, so far, at least 16 major claims made in AR4 (the report for which the IPCC won a Nobel Prize) have been shown to have originated with environmental groups rather than scientists, including the claim that climate change is already making tornado, hurricanes, forest fires and floods worse.
This week, we also learned that NASA’s Goddard Institute for Space Studies (GISS) may have been playing fast and loose with its own calculations of global average temperature. Among the four main repositories of global temperature records, GISS is the only one to show the Earth still warming during the past decade. Now two American climate researchers — Joseph D’Aleo and Anthony Watts — believe they know why: Scientists at GISS may have been cherry-picking the weather stations they take their records from to increase global averages artificially.
The pair write that there was a “major” decline in the number of stations GISS scientists were taking readings from “and an increase in missing data from remaining stations, which occurred suddenly around 1990 … a clear bias was found toward removing higher elevation, higher latitude, and rural stations — the cooler stations — during this culling process.” The pre-1990 temperature records, though, continued to include these cooler stations. These changes tended to make temperatures before 1990 appear extra-cool and those after 1990 extra-warm.
For some reason, I can’t shake the image of a lead climate expert having his scientist mask ripped off to reveal his true identity as Al Gore, who’ll say (of course) “And I would have gotten away with it, if it weren’t for you skeptics!”
