It's a process of elimination. The orbital/tilt factors say that the Earth should be getting cooler. The solar radiation levels are stable. It is a known fact that we are burning fossil fuels and cutting down rain forests, thereby releasing 7 gigatons of CO2 into the atmosphere each year. The atmospheric CO2 level goes up each year. The average global temperature is increasing.

I suppose that it depends upon the level of proof one requires to say that such and such is true.

The carbon cycle makes it vastly more complicated than that.

In what way? To me, the carbon cycle just means that the level of atmospheric CO2 will continue to rise for at lest the next hundred years.

Just watching an interesting program on National Geographic. The commentators on this documentary were saying that the mutation that is most likely responsible for distinguishing humans from lower functioning apes was a mutation resulting in the weakening of jaw muscles. This mutation ultimately affected skull morphology since stronger muscles require denser (less flexible) bone to attach. The lack of stress from the muscle ultimately resulted in the increase in brain/skull size. The second most important mutation occurred much more recently which was a mutation of FOXP2 which allowed the formation of neural connection to control the tongue and mouth enough to articulate language. Only two amino acids separate our FOXP2 from that of chimpanzees.

That was funny and I owe you a green dot.

I'm hoping my monkey will be the first to learn to talk!

The question is do you like to spank the monkey?
