Bronco - methane is more potent per molecule, but much less abundant in the atmosphere than CO2, and with a much shorter atmospheric lifetime. For that reason, CO2 is a far more potent driver of current warming than methane. Most important, anthropogenic CO2 emissions have been raising CO2 levels at increasing rates, while methane has remained relatively stable (although a resumption of some methane increases has been noted recently, possibly from wetlands). This accounts for emphasis on CO2.

Oh, so now my truck is to blame for famine and warfare in Africa? And for the record NASA says the sea level is at the same level it was at twenty years ago, there's something to worry about.
Explain this because your more intelligent than me: Methane is 24 time more powerful as a greenhouse agent than CO2, do a little math and that means a COW does more global warming than an Escalade driven 10k miles a year. There are THREE BILLION cows in the world, and just over half a billion cars.

The more the sun stays quiet the more the earth will cool and the longer it will take to warm the earth back up once the sun becaomes very active again.
Once more, i did not say that 2008 was the 3rd coolest in the last 100 years.
icecreamdose (November 30, 1999 at 12:00 am)
my logic? i didnt imply anywhere that 2008 is the 3rd coolest year in the last 100. But i certainly do imply that the earth is cooling and the leading factor for that cooling is the inactivity of the sun. There is a lag in time between an inactive sun and the cooling of the earth. It's like shutting off the heat on boiling water. The water is still hot when you do, but at that moment it starts cooling.

I won't comment... -grastog
I think you should. In most cases, people will not accept your explanation over theirs when they see no failure in their explanation.

errr broncoman you dont know much about climate change history do you? read what happened in the Permian-Triassic extinction event, and thats only a 5C rise over a much longer period of time then what we predicting will happen because of this

Actually, broncoman, floods, droughts, and heatwaves have increased during the last 100 years of anthropogenic warming, with serious consequences. Drought-related crop failure leading to famine and "climate wars" has occurred in Africa, and thousands of excess deaths have resulted from hurricane storm surges heightened because they arose on sea levels elevated by warming. Some of the quantitative data are cited in AR4 WG1. A major concern now is increased harm from similar events in the future.

There have always been floods, droughts, hurricanes, typhoons, tornadoes, cyclones, heatwaves and cold snaps. FACT: The occurrence of these things has not changed from the last degree of warming, neither in intensity or number. Why will the next degree of warming make the world uninhabitable? I think that in time people will look back on the hysteria over Global Warming and laugh at all the time and money we spent on it, just like we make fun of ancient alchemists and doctors who used leeches.

I won't comment on steam, hydrogen, and laminar flow, which don't seem relevant to warming driven primarily by CO2, based on its infrared absorbing properties. However, it's worth mentioning that solar influences on climate exist, but are small compared with CO2 effects. The current solar minimum appears to be ending and solar flux increasing again. Sunspots are a very rough guide to this, and the precise irradiance data from satellites can be found by Googling SORCE.

So H2O goes to He and O with excess heat? Where do the two extra neutrons in He come from? The covalent bond energies in water is vastly insufficient to produce neutrons from the vacuum. To learn what happens when you separate a water molecule, I would suggest googling electrolysis of water.
Furthermore, cold fusion is denied by experiment and theory.
