Heads Up: Global Climate Change Denial Bashing
What a wonderful post!
This individual manages to do a wonderful job at doing three things.
First he does a reasonable, measured smackdown on a global warming denier ‘Jack’. In calm measured tones (and with graphs), he points out that while measurements from the Vostok ice cores do show a variation in temperature over time, they are only part of the picture.
Yes, the chart does show that CO2 and earth’s temperature have risen and fallen over the past 400,000 years. No one is claiming that these variations were caused by humans, in fact how the Earth manages to stay within this narrow range of temperatures and CO2 concentrations is the subject of a great deal of debate and research. The point here, is that even with natural variation, these values have stayed within the range shown above for 400,000 years.
This is where global warming comes in. Early in the 20th century the atmospheric CO2 passed 300 parts per million and just kept on rising. In 400,000 years the natural variation never topped 300 ppm, yet in the last few decades CO2 has gone 25% above that. And amazingly enough, this rise coincides neatly with humans dumping CO2 into the atmosphere at ever increasing rates. This is human caused global warming, and this is what increasingly cannot be explained away as “natural variation.”
Second, he manages to do a wonderful job of showing the inane stupidity in the following comment,
What do you think? Is it possible that those people who think the Iraq war was a good proposition could actually be right on the global warming issue? Or are they a related subset of each other?
And, perhaps as a piece d’resistance, he has both cats and a really cool mustache.
