Rehash.
So, Chris Matthews wanted to know if the Republicans are anti-science. He invited a Republican and a Democat on his show to discuss. The Republican did a fantastic job of sowing doubt…by rehashing all of the old, tired and debunked anti-anthropomorphic climate change arguments. The Democrat and Matthews didn’t have the science background to discuss any of these. So, why not have a real scientist join in the debate? A scientist would have cleaned the Republican’s clock.

Dana Rohrabacher’s (R-California) big “science” points and rebuttals.
1. Change in temperature on Mars and Jupiter.
Mars has a very thin atmosphere and has frequent dust storms. Large dust storms change the albedo of the planet and reduce the reliability of telescope-based temperature measurements. The empirical data is not conclusive for climate change on Mars.
Heat transfer within Jupiter’s atmosphere is very complicated. Temperatures are increasing in equitorial regions, but cooling in polar regions.
2. Historical fluctuations in Earth’s temperatue.
No one denies that Earth’s climate fluctuates. However, the natural causes for climate change have remained relatively stable since the 1970’s. The change in global temperature that we are seeing is due to human impact on the atmosphere.
3. Temperature has not increased since 1998.
1998 was abnormally warm because of a very strong “El Nino” effect. Long-term global mean temperatures show a statistically significant increase in temperature over the past decade.
4. It is the Sun.
The correlation between increased sunspots and increasing temperature ended in the late 1970’s or early 1980’s. Sunspot activity is decreasing, yet temperature continues to increase.
4. Greenland used to be green.
Dana claims that 1000 years ago, Greenland used to be green. The current ice sheet on Greenland is at least 110,000 years old and Greenland has been ice covered for hundreds of thousands of years.
