On this new "clouds" postulate that was back in the thread a bit....
Clouds, as of now, DO reflect a portion of solar irradiance. It all depends on what the clouds are made of... look at Venus...clouds there tend to reflect a small percentage and hold the rest IN. Can anyone tell me what clouds on Venus are made from? Bonus question... Titan, moon of Saturn, come up with atmospheric composition and deviation from expectected surface temperature....
On solar forcing of global warming.... and Mars....
Mars is warming, currently. Earth is warming currently. Posters have drawn these two events and tried to tie them together. If solar forcing was truly doing this... wouldn't the other planets.... in particular VENUS be showing the same...considering it's closer to the sun than either of the other two????? Venus isn't warming. Mars and Earth's events are not tied together..... and can be further refuted by the fact they are warming at different RATES...if the same variable was working upon all three, all three would be showing the SAME RESPONSE to the VARIABLE, at least in rate response to external forcing.
