By the time we factor everything it'll be too late

Q: With the recent discovery that methane is bubbling out of the Arctic faster than expected, how worried should we be about abrupt changes in climate such as this one? Are there precautions we should be taking that both the political and scientific communities have been overlooking?

As if the question about human intervention in any rise in the earth's temperature wasn't complicated enough, now we have the factor of increased methane releases from tundra areas where the permafrost is melting as the temperature rises. Of course methane, which can hold 30 times as much heat as CO2, isn't a new problem. We've long known that gaseous releases from cows put a LOT of methane into the atmosphere.

Once again we need to factor into the global warming equation yet another unknown symbol. By the time we figure out the exact values for the unknowns it will be too late to change the factors in any meaningful way to limit the amount of human caused consequences. Like a train that is picking up speed, the further along the track it goes, the longer it takes to reduce the velocity back to where it was a short time ago. The longer we wait to act, the longer it will be to effectively limit the consequences humans have contributed toward the way of life for our descendants.

We know we can alter the local weather, such as in the Los Angeles basin, where smog exists. During the Northeast (U.S) power gird shutdown of 2003 air quality improved temporarily in a large area of the northern eastern seaboard, and then pollution was quickly regenerated when the power stations came back online. If we can change the atmospheric chemistry in local and regional situations, why do some think it is impossible to change the whole earth's atmosphere after 250 years of increased production of gases caused by the burning of fossil fuels?

We have seen the benefits of the Clean Air Act of 1983 and other legislation which has helped reduce the pollutants that cause health and other problems. Apparently the reduction of CFCs into the air has decreased the area of ozone depletion. It seems humans can reverse the impact caused by what we put into the atmosphere. While global warming is on a much grander and much more complicated scale, I would hope we would do whatever we can to leave the planet to future generations as much like we found it as possible.

Mr. Edmund:

"If we can change the atmospheric chemistry in local and regional situations, why do some think it is impossible to change the whole earth's atmosphere after 250 years of increased production of gases caused by the burning of fossil fuels?"

No serious climate skeptic denies that warming has occurred recently, not that humans have put more CO2 into the air as the level of industrialization has increased.

What is in question is whether the additional CO2 has any real probability of changing global temperatures. Climate 'scientists' like Drs. Jones and Hansen used data sets and programs that they refuse to release to other scientists to produce reconstructions of past temperatures and forecasts of future temperatures than cannot be independently verified. Jones 'lost' much of his data, and falsely claims that the countries who provided it will not allow him to release his adjustments to their data.

Global temperatures were probably warmer than today during the Roman Empire, and certainly again during the Medieval Warming Period. As a student of events surrounding the time of Jesus, you should know this. The written records kept by the King of Norway document taxes on wine made from grapes in Greenland where grapes cannot be grown today because it is too cold. Written records also exist for other countries from this time period.

It is nice that people who believe in this are willing to invest in wind mills and solar panels, but are you really prepared to deny basic human amenities like electricity to most of the third world by preventing them from using coal to produce electricity? Are you willing to do this based on what is clearly questionable scientific work that, in my opinion, will be discarded in the next few years.

There was a lot of noise about drowning polar bears and open shipping lanes in coming summers between Norway and Japan. The polar ice has increased substantially this winter, and no one is likely to be sailing to the north pole any time soon. The south pole ice is above recent levels for this decade, and you are very unlikely to read that in any publication that also published pictures of drowning polar bears. Why is that>
