Some Like it Hot

On the heels of Michael Crichton's State of Fear novel and the flawed Kyoto Treaty signing, global warming has been making its usual rounds in the news lately. Roaming around the net, perusing various websites and columns, it depends on what statistics and which scientists you want to believe.

In a Reuters release, we can be assured that man creates global warming.

Studies looking at the oceans and melting Arctic ice leave no room for doubt that it is getting warmer, people are to blame, and the weather is going to suffer, climate experts have said.

But wait a second, maybe it's the sun...

Global warming has finally been explained: the Earth is getting hotter because the Sun is burning more brightly than at any time during the past 1,000 years, according to new research.

A study by Swiss and German scientists suggests that increasing radiation from the sun is responsible for recent global climate changes.

Maybe not man nor the sun? I guess it could be just natural cycles.

Periods of Earth warming and cooling occur in cycles. This is well understood, as is the fact that small-scale cycles of about 40 years exist within larger-scale cycles of 400 years, which in turn exist inside still larger scale cycles of 20,000 years, and so on.

Hold the phone. Ruth Curry of the Woods Hole Oceanographic Institution warns us about the shrinking solid H2O: (emphasis added)

"Ice is in decline everywhere on the planet."

The penguins of ice-thickening Antarctica disagree.

The new study finds that "Our spatial analysis of Antarctic meteorological data demonstrates a net cooling on the Antarctic continent between 1966 and 2000, particularly during summer and autumn." The McMurdo Dry Valleys, for example, have cooled about 0.7 degrees Celsius per decade during this period of time.

The authors conclude that, "Continental Antarctic cooling, especially the seasonality of cooling, poses challenges to models of climate, and ecosystem change."

And the debate continues...
