Just one graph should be enough to kill the whole Cap-n-Tax Debate.
This graph, compiled by Ex-CSIRO scientist Dr Guy LeBlanc Smith PhD, AIG, AAPG, from data obtained from deep core drilling on the Greenland Ice Sheet, shows that all life on earth now, including polar bears, coral reefs and humans, have survived massive sea level changes and rapid and dramatic changes in earth’s temperature. There were no coal fired power stations and no gas guzzling cars to cause these changes then, and the same natural forces will change the future. Humans will need wits and resources to cope with future changes and every diversion of our resources to nonsense like Cap-n-Tax will reduce the chances that we will survive future changes.
The real danger to all life on earth is NOT warming and abundant aerial plant food (carbon dioxide) – the real threat is ICE and plant starvation.
