Global Warming Debunked?

limbicsystem writes, "I'm a scientist. I like Al Gore. I donate to the Sierra club, I bicycle everywhere and I eat granola. And I just read a very convincing article in the UK Telegraph that makes me think that the 'scientific consensus' on global warming is more than a little shaky. Now IANACS (I am not a climate scientist). And the Telegraph is notoriously reactionary. Can anyone out there go through this piece and tell me why it might be wrong? Because it seems to be solid, well researched, and somewhat damning of a host of authorities (the UN, the editors of Nature, the Canadian Government) who seem to have picked a side in the global warming debate without looking at the evidence." The author of the Telegraph piece is Christopher Monckton, a retired journalist and former policy advisor to Margaret Thatcher.

The issue isn't. . .

whether global warming is happening. We know it is. We're recording it as it happens.

What is the issue is is this a natural process, a man-made process or a combination?

While we have evidence that warming and cooling cycles have happened in the past, this is the first time (that we know of) that the cycle has been recorded by man. If nothing else, it behooves us to study this phenomenon as critically as possible and determine if we are influencing things by our activities.

So no, global warming is not debunked. It is real and it is happening. The real question is why.

So...yea...that's why it's wrong.

in anything." - G.K. Chesterton.

There ya go. From his preface. People believe in climate change because they have lost their faith.

If that's not his argument...why is this one of the first things he says?

Also, he cites the concept that all climate scientists are saying there's a problem so they'll keep their jobs...before he gets to any actual numbers.

Then he says this...

The snows of Kilimanjaro have been receding. So have the glaciers in Glacier National Park,
Washington State, and many other (though not all) mountain glaciers in temperate or equatorial
latitudes. However, very nearly all of the world's 160,000+ glaciers (this surprisingly large figure is
from the UN's 2001 report) have never been visited by humankind or measured in detail. They are on
the high, central plateaux Antarctica and Greenland. The great majority are not melting. They are
growing.

This is not true.

Then he says.

I conclude that the rise in temperatures since 1900 has been far from uniform globally. Overall,
temperatures may have risen at only three-quarters of the rate assumed by the UN in its 2001 report. As
will be seen later, even a small discrepancy between the UN's assumed 0.6C and the true 20th-century
increase in temperature has a significant effect on the calibration of climate-projecting models, and
hence on the magnitude of their projections of future climate.

Which is a classic mistake of mistaking weather for climate..and local for global.

Then he says it's not greenhouse gases...but the sun that is getting hotter.

I conclude that the Sun is very likely to have contributed rather more to the past century's warm period than the UN has assumed, and that assumptions about the contribution of greenhouse gases to warming should be revised downward accordingly.

So, uh, it's not even that it's "global warming" that has been debunked...it's that the U.N. is wrong about what is causing it.

(yes, the headline is wrong).

Then he goes into the calculations...none of which is data he personally gathered (because if he did, that would be he is a climate scientist...which would mean he couldn't be trusted...as he would then be being paid to study the climate).

So...yea..that's why it's wrong.
