Curbing CO2 will not make much difference



Washington Post:

Greenhouse gas levels currently expected by mid-century will produce devastating long-term droughts and a sea-level rise that will persist for 1,000 years regardless of how well the world curbs future emissions of carbon dioxide, an international team of scientists reported yesterday.

Top climate researchers from the U.S. National Oceanic and Atmospheric Administration, Switzerland and France said their analysis shows that carbon dioxide will remain near peak levels in the atmosphere far longer than other greenhouse gases, which dissipate relatively quickly.

The Chicken Little globo warmers are screeching up their rhetoric as Washington faces another snow storm.

Talk about climate change--Right now it is 70 degrees and overcast in Washington, Texas, but this evening we are supposed to get freezing rain. Warm is clearly better.

I am skeptical of the forecast of rising sea levels and droughts. It seems to ignore the effects of the bodies of water on precipitation. The summer weather pattern over the Gulf coast is typical. Clouds form over the gulf at night because the water is warmer than the land. During the day, the clouds drift toward the land mass as it heats up and usually in the late afternoon they dump a rain shower and then drift back to the Gulf to start the process again. If the forecast is as dire as the globo warmers predict that will only increase the rain bearing clouds dumping on the land.

You have to also consider that there will continue to be temperature differentials between winter and summer, so that water will still be freezing for at least a part of the year even if the scary forecast is realized. Will that result in large tidal differences that can be exploited for energy?

I think what may be going on with this new forecast is an attempt to preempt arguments when restricting CO2 does not work.

I think there is also a basic flaw in the argument for the greenhouse effect. The earths atmosphere protects it from the suns rays, as well as the extremes in temperature when a portion of the Earth is not being warmed by the sun. Is it just a coincidence that the temperatures have increased since we have been removing pollution from the air allowing more of the suns rays to penetrate the atmosphere?

It is a good thing I like warm weather.
