Climategate, Copenhagen, Snowmageddon in the nation’s capital, the EPA ruling that CO2 endangers us all, and Senate Republicans pushing for a global-warming tax. Has it been a great run-up to Earth Day, or what?
Never has a public-policy agenda been pursued with so little regard for scientific fact or public opinion. In March, 48 percent of Americans agreed that global warming, while real, is exaggerated. When Gallup first asked this question in 1997, only 31 percent thought the threat exaggerated.
Despite this shift in sentiment, Sens. Lindsey Graham (R., S.C.) and John Kerry (D., Mass.) and President Obama insist upon ramming a new global-warming tax (called a “fee”) through the Senate. The bill is slated to be introduced next week, and vulnerable Democrats — weary already from the pugilistic health-care debate — are fleeing the legislation in droves.
And for the measure’s primary backers, the backdrop of recent developments on the climate-science landscape could not possibly be less fortuitous.
Climategate revealed that a small but influential coterie of climate scientists did everything they could to present messy global-warming data as a “nice tidy story,” meticulously crafted to “hide the decline” in tree-ring-based temperatures. (I use quotes because those are the words of the warming-alarmist scientists themselves.)
The fact is that tree rings are pretty poor indicators of annual warmth, especially in recent years. Dendrochronologists call this the “divergence” problem (cynics call it other names). Phil Jones, the central figure in Climategate, actually eliminated the “divergence” rather than “hiding the decline.”
The amount of “explained variance” or statistical correlation between rings and temperatures during the summer growing season tends to run about 40 percent. That means more than half of the temperature changes for a fraction of the year (and even more for the entire year) are unexplained.
