Earth's climate has shifted all through the ages. The real question is was it all bad for the Earth? Take for example, South Dakota. It once had a glacier over the Eastern half. Now that part of this country is very productive in agriculture. Same for the whole states of Ohio, Indiana, and Illinois. Chicago used to be under a mile of ice. So if someone is trying to scare anybody about Climate Change ask them what kind of climate change, and be specific.
Now when you ask about Catastrophic Anthropogenic Climate Change, that is a different issue. It is total crap. It is a political movement and has no scientific credibility. Even the proponents acknowledge this.
Quote by Christine Stewart, former Canadian Environment Minister: “No matter if the science is all phony, there are collateral environmental benefits.... climate change [provides] the greatest chance to bring about justice and equality in the world.”
Quote by Timothy Wirth, U.S./UN functionary, former elected Democrat Senator: “We’ve got to ride the global-warming issue. Even if the theory of global warming is wrong, we will be doing the right thing in terms of economic policy and environmental policy.”
So even though the strongest proponents don't trust the science behind their scam, then why should I?
