A Climate skeptic’s epiphany response.
Eugene Robinson of the Washington Post started his op-ed with the sentence: “For the clueless or cynical diehards who deny global warming it is getting awfully cold out there”.
Yes, indeed. It is getting cold alright.
Robinson quoted Richard Muller, a true scientist, as having said “Global warming is real”. Muller did that by noting what skeptics already know that we were having a warming trend between 1970 and 2000. He then presented the data with a 10 year moving average, making the end time 2006. This data resembles the famous “Hockey stick”, with a rapid and accelerating temperature rise. Muller also pointed out that of all temperature stations one third show a cooling trend. All stations monitor CO2 filled air, so what makes the difference? A separate analysis shows that weather stations in continuous use since the year 1900, located in an unchanging environment show no warming trend between 1900 and 2010, while weather stations in airports and near paved parking lots, buildings and air conditioners do. A thinking person would conclude that something else than rising levels of CO2 would be the cause of rising temperatures. It seems to me that land use changes would play a major role, since only those weather stations that are subject to land use changes show an increase. Since 2000 we have had a cooling trend of about 1 degree Fahrenheit/century, and the cooling seems to be accelerating. We have not had a major volcanic eruption since Mt. Pinatubo in 1991, so something else must be the source of our present cooling trend. Cosmic radiation resulting from low solar activity leading to more clouds has a near perfect correlation with temperature data for the last 30 years. Yeah, that’s it. Maybe we get our heat from the Sun! True global warming skeptics to not deny climate change, nor do they deny CO2 being a greenhouse gas. The latest data indicate that if the amount of CO2 is doubled the global temperature would rise about 0.3 degrees Celsius, rather than the 1.5 to 5 degrees that IPCC(A U.N. panel) has guessed. This temperature rise is largely concentrated in the temperate regions of the world and would be mostly beneficial. In addition, with a doubling of the CO2 level, crop yields would increase 30 to 45% allowing the earth to feed that many more people.
What is so horrible about that?
Towards the end of the paper the scientists conclude: “The human component of global warming may be somewhat overestimated.”
I love understatements.
