It doesn't matter. The angle of incidence (the Sun's tilt angle towards the Earth) changes as the seasons change. Remember the Earth is eleptical like an egg so it wobbles as it rotates around the Sun. This changes the distance that the hemispheres have as the Earth makes it yearly rotational cycle through our galaxy. This means that you have less sunlight for photosynthesis in the winter time. More CO2 won't change the fact that you still don't have enough sunlight to complete the photosynthesis process. This also means that the heat that did build up during the day is able to more rapidly escape the Earth unless clouds roll in after a sunny day and trap the heat down closer to the Earth's surface. This effect is not consistent.

If there is not enough sun getting to the surface of the earth during winter for photosynthesis, explain greenhouses.

There IS no hard evidence which is why we never see it.

I used to be an AGW subscriber, having considered myself an environmentalist all my life, an early adopter of both Rachel Carson and Frances Moore Lappé and having taken my first Ecology course in 1967.

Once I realized, sometime in 2008, that we were being herded into the anti-coal=pro-nuclear, I took a closer look at the evidence and found that it didn't exist in a plausible, scientific way: with carbon-based life on a carbon-based planet how, exactly, can CO2 be problematic?

Why Can't Johnny do Science (and Logic)?

Why did AL Gore ask Timothy LaSalle to "dial down" his carbon-sequestering plan?
