Nobody is going to convince me of impending doom over such inconsequential fluctuations in temperature

So, you're a climatologist? How do you know the signs of impending ecological disaster? Me, I like to rely on the experts, who overwhelmingly believe we could be heading for a disaster:

That's why, with glaciers and sea ice melting and rainfall patterns shifting, scientists smell a stacked climate deck. "We have never seen natural variability on a global scale like we've had in the last 100 years," says atmospheric physicist Michael Oppenheimer of Princeton University.

A study released last week also found evidence of a stacked deck. Scientists analyzed historical barometric data to infer the strength of winds across the tropical Pacific. This "Walker circulation" consists of high-altitude westerlies and surface easterlies. It has weakened by 3.5% since the mid-1800s, Gabriel Vecchi of the Geophysical Fluid Dynamics Laboratory, part of the National Oceanic and Atmospheric Administration, and colleagues reported in Nature. That has yet-unknown consequences for marine life and regional rainfall.

Again, changes in the sun's output since 1861 are too small to have warmed the world enough to weaken the Walker circulation that much, the scientists calculate. Adds Dr. Vecchi, "We looked at 2,000 years of data and asked whether internal variability could produce the weakening. There is less than a 1% chance it did."
