Scientists already are pretty certain that sun spot activity is related to global temperature somehow (more spots = warmer, fewer = cooler) and the previous IPCC report specifically mentioned that for previous warming and cooling periods, but dismissed that for this latest warming period.
The Daily Bayonet has a roundup of environmentalist nonsense news every Friday I encourage you to check out, and in the roundup for last week, this number was highlighted:
Let me put that number into more easily visualized form:
3.86×1026 J is the amount of energy put out by the Sun every second. It’s a big number. Even varying it by 0.1% is still a big number.
380 parts per million is (roughly) the amount of CO2 in Earth’s atmosphere. It’s a small number. It gets smaller when you take out all the natural sources of CO2 and accept that man’s contribution is only a very small percentage of that 380 ppm.
Which do you suppose might affect the weather more?
The sun puts out 386,000,000,000,000,000,000,000,000 joules of energy per second of which about
*Commenter Tom Dickson-Hunt corrects my estimate here: "The Earth is tiny in the sphere of its orbit; the real number is in the neighborhood of 10^-5 %. "
By comparison your 100 watt lightbulb puts out 100 joules per second. A .44 caliber handgun bullet puts out 450 joules on a very small point of impact. The head of a matchstick has about 1000 joules of energy in it.
That sun is so hot it burns skin in a matter of hours and can completely blacken and burn tissue within days. Its so hot it warms an entire planet in a matter of hours by up to 50 degrees Fahrenheit. That immense ball of energy up there affects the temperature of the earth - and every other planet in the solar system.
Oh, and that arctic sea ice that Al Gore is weeping over? A recently released peer-reviewed (the magic words which the alarmist loves to throw around) study shows that arctic sea ice in the north pole is unusually high these days. Anthony Watts at Watts Up With That has the details:
A peer-reviewed paper published in the Canadian Journal of Earth Sciences finds that Arctic sea ice extent at the end of the 20th century was more extensive than most of the past 9000 years. The paper also finds that Arctic sea ice extent was on a declining trend over the past 9000 years, but recovered beginning sometime over the past 1000 years and has been relatively stable and extensive since.This begs one of those questions alarmists never seem to be able to answer: what, exactly, is the proper temperature of the earth? How do we know if its getting too warm or cold, unless you have that number? Preservationists seem to think that the way things were when they were younger is the way they should remain forever without any change. The world just ain't like that, kids.
