Somone answered another question of mine talking about global warming being a product of our solar system in general being warmed somehow.
Anyone ever heard of this, or have any ideas about it?

"Yes, its the way the Earth is turning on an uneven keel, meaning that over thousands of years the Ice caps turn a bit closer to the sun melting them while putting some other parts of the planet further from the sun than they was.
We cannot stop global warming as it is in the natural cycle of things. "
What the hell? Did you even bother to read the entire question?

The Sun has increased the level of radiation it's emitting. This is well established science and there is a lot of data, measured by various people in various places, with good agreement.
But it's not enough to explain the temperature rise on Earth. The IPCC scientists did the calculation. The result is not in any way controversial.
http://www.ipcc.ch/SPM2feb07.pdf
On page 4. The increase in solar radiation is 0.12 watts per meter squared. The increase due to human activity is 1.6 watts per meter squared, more than ten times as much.
So, yes, the sun is warming up just a bit and no, it's not a major cause of global warming.

The average temperature of the earth is determined by the balance of the heat gained from the sun's radiation and the earth's radiation back out into space. I have read that the sun's output has increased by .1% but most scientist don't think this could account for the increase in the temperatures that have been observed. Modeling the climate is a complicated problem which is why computer simulations are used. To find the equilibrium temperature you need to calculate a small difference between two large numbers, both or which is hard to determine. It is easier to get a fairly good estimate of the effect of an increase in the solar radiation, so I would trust the scientist on this, even though their temperature projections have large uncertainties.

Yes there are natural cycles of hot and cold weather. BUT, the current rise in temperatures cannot be explained by any natural cycle. Also, the amounts of CO2 in the atmosphere is higher than anything we have measured in the last million years. The new IPCC report states that the only reasonable explanation for the rise is human activity.
Even if we stop CO2 production now we will still have to deal with some extreme weather and disasters. Doing nothing will only make things worse in our lifetimes.

Scientists noticed that Mars has been warming over the last couple of decades as well. I find it hard to believe that it is due to anything we did.
If the trend observed on Earth is the same as that on other planets, I must conclude that the Sun is the most likely source.
