题目: From the American Thinker:

A study
released yesterday confirms that global temperatures have remained flat
since 2001 “despite rising greenhouse gas concentrations” and predicts
they may cool for another 30 years. Needless to say, that won’t silence
any of the blowhards attacking George Will’s February assertion that “there has been no recorded global warming for more than a decade.”

you can thank me later

Artful Dodger: A Quote from your link to the study:

Swanson thinks the trend could continue for up to 30 years. But he warned that it's just a hiccup, and that humans' penchant for spewing greenhouse gases will certainly come back to haunt us.

"When the climate kicks back out of this state, we'll have explosive warming," Swanson said. "Thirty years of greenhouse gas radiative forcing will still be there and then bang, the warming will return and be very aggressive."

题目: Re: From the American Thinker:

Artful Dodger: It's inconsistent.....

It says..... "Following a 30-year trend of warming, global temperatures have flatlined since 2001 despite rising greenhouse gas concentrations, and a heat surplus that should have cranked up the planetary thermostat."

and then.... "This current cooling doesn't have one."

Flatlined or cooling, which is it?

>>>>>>>>>>>>>>>>>>>>>>>>>>

Then.....

"How does this square with temperature records from 2005-2007, by some measurements among the warmest years on record?"

and .... "When added up with the other four years since 2001, Swanson said the overall trend is flat,"

This to me confirms that the weather HAS got warmer over the last 3 years, also that misusing stats doesn't work. It'd be more accurate to use the 2008 temp figures to see how the current trend is going. Averaging out doesn't always give an accurate answer when dealing with trends.
