http://philosophy.wisc.edu/forster/paper... is a good place to look. It talks about myths and who is funding bad science to support profit.
There is a time bomb in all of this. I lived in the arctic until recently, and I watched more than 1000 new lakes of 20 acres or more appear in the last 10 years, in a 20,000 square mile area. Some scientists have calculated from random sampling of tundra permafrost in Alaska, Canada and Siberia, that if the permafrost melts it will release 80 times as much greenhouse gases as our industrial uses have done, and that may happen in as short a time span as 50 years. It took us about 150 years of industrial uses of fossil fuels to more than double the CO2 in the atmosphere. Imagine what the melting permafrost could do?
Sea level rise? Between 8 and 30 meters, most say. The debate is about how long it will take. We are already able to observe an increase, and the polar icecaps are diminishing. The arctic cap is meaningless, because the ic is already in the water, so no net change in level will come from it though it is retreating at 8% per decade for the past two decades nd the retreat seems to be increasing. Most of that mass of water is in Antarctica and the movement of that amount of mass away from the axis of rotation could affect the length of the day and possibly cause an increase in vulcanism.
Vulcanism could add to the greenhouse or tke away from it. If the surge blows rock dust into the upper atmosphere, then it may cause a lessening of insolation (heating from sunshine) and counter some of the warming.
But right now, Tuvalu is about a meter above sea level, and the residents are worried about losing their home. http://www.pbs.org/frontlineworld/rough/... will tell you more, and the author is a Fulbright Scholar as well as a competent journalist nd cites plenty of scientific sources.
The idea that there are two sides to global warming is hardly defensible. It is happening. How long is the question, and how severe is the other. Personal observations, KOTZ radio news. National Public Radio, the web sites I mentioned and the other links it will lead you to,.
