NoaIzumiBaby It's Cold Outside, by Emmett Tyrrell

In winter, the global warming skeptics come out. Well, they’re out all the time, but in winter they get more vocal. “It’s cooler than it was three months ago, global warming must be over!” I guess that’s the logic. It’s certainly the logic in this piece.

Granted, 2008 has been a relatively cold year, but it’s not because CO2 stopped being a greenhouse gas all of a sudden, but because of La Nina,

The Earth hasn’t been cooling since 1998, either. According to NASA, 2005 was the warmest year ever recorded, which would make it warmer than (or at least statistically indistinguishable from) 1998.

And check out the chart from NASA’s Goddard Institute for Space Studies:

“it also may be caused by natural activity on the sun.”
Uh, no it may not, not unless natural solar activity goes up. Over the last thirty years, solar activity (and sunspot activity) has been relatively stable. I fail to see how the sun could be causing a warming change when solar activity itself hasn’t been increasing.

“The computer models that have predicted global warming have failed,”
They haven’t, but the folks at Gristmill can explain it better than I can
Really Long Link
"Actual observations suggest that the sensitivity of the real climate is much less than that found in computer models whose sensitivity depends on processes that are clearly misrepresented."
The problem is, “actual observations” are misleading in this case, in two ways. For one thing, the implicit assumption in the statement is that CO2 rise has an instantaneous effect, which it doesn't. For another, Dr. Lindzen completely ignores the dimming effect, which cools the Earth, partially counteracting warming due to carbon dioxide.
