You cannot make things like this up.
Inhoufe of Oklahoma, the leading global warming denier in the Senate, said this to Rachel Maddow:
“I was actually on your side of this issue (accepting the established science of climate change) when I was chairing that committee and I first heard about this. I thought it must be true until I found out what it cost.”
I like what Michael Kingsley said, "a gaffe is when a politician tells the truth."
"It is the power of thought that gives man power over nature."
Hans Christian Anderson
I was skeptical about 20 years ago, but three independant things have convinced me that the planet is warming and human hydrocarbon and carbon burning has caused it.
1. The scientific evidence is well established. My wife is a biology professor and basic environmental biology texts teach anthropogenic global warming as established science. Climatologists universally accept the science and only a handful reject the anthropogenic cause.
2. Neutral barometers of climate change are present everywhere. When I lived in Minnesota, opossums were extending their range north in to Minnesota. Thirty or forty years ago they could not survive there because of the sub-25 degree winters. Tempatures have warmed and they react to the changes. Many other plants and animals have changed habitat because of these changes.
3. It took hundreds of millions of years to store all of the carbon and hydrocarbons (coal, gas and oil) in there huge underground concentrations. A time scale we cannot even imagine. But in only 150 years or so, humans have consumed and released much of this carbon back into the atmosphere. How can that not have a major impact on the climate?
This is the kind of talks I have been watching.
