Twenty years ago, when Dr. Hansen first gave his presentation before Congress, much of what we see happening right now was probability. It is now fact.
We, as humans, have only been here about 200,000 years. As Homo, maybe 1.5 million. And we have been affecting the climate by our actions only about 6000 years. However, for the last 150 years, we have been having huge effects on the climate and our environment. Everything from deforestration to changing the composition of the atmosphere.
