You Have to Be Living on a Different Planet to be a Climate Change DenierMay 11, 2013
Oh the arrogance. “We should be able to do whatever we want to do.” “Freedom means free to change the world in any way we want.” “Scientists are just trying to scare us”. Well, now it’s official, the scientists who know about this stuff are scared. We have failed miserably at reduced emissions of carbon dioxide and related global warming gases. We are now seeing levels of carbon dioxide in the atmosphere that haven’t been seen in over 3 million years. And there is no sign that this is going to slow down any time soon.
The following charts were presented in the New York Times. Have we passed a point of no return? No one knows. Are we gambling with the future of the planet and our children and their children. Definitely.
The following chart (gained through ice samples I believe) shows the carbon dioxide concentration over the past few hundred years. It’s a band between 200 and 300 parts per million. In the past few decades we’ve broken out of that band with extremely fast growth.
This chart shows the steady increase in atmospheric carbon dioxide over the past 50 years. The really scary thing is that we don’t know how bad things will get at 400 parts per million and there are no policies in place to prevent these levels from going way, way higher in the future.
