I beg to differ...here is a graph that shows a estimate of temperatures for the last 1000 years.

And another one showing the temperature from 1860 till now.

I see a increase in temperatures in the last 100 years. Now i see it as two things. Either generated by the presence of humans or the planet being 4.5 billion years old is just going through another inevitable cycle. I just hope im in a better place along with my future children and grand children before things turn sour.


Just my 2 cents.
