Only a partisan idiot would sign a letter that begins with this....".The U.K. Met Office recently released data showing that there has been no statistically significant global warming for almost 16 years. During this period, according to the U.S. National Oceanic and Atmospheric Administration (NOAA), carbon dioxide (CO2) " and consider it at all relevant. If someone does NOT know how irrelevant this "fact" is (actually a cherry picked two points on a fluctuating chart of yearly average temps)they are simply an idiot, or ignorant, or a partisan hack. I suspect the latter is the case here. There is no change in trend and the trend is up. Over 98% of the world's CLIMATOLOGISTS, not physicists, not meteorologists, not geologists..... CLIMATOLOGISTS concur, the emission of vast quantities of the greenhouse gas CO2, due to the burning of coal, oil and gas, is raising the temperature of the earth. If in fact one were to poll all of the aforementioned scientists who are not climatologists, over 90% would also agree. Every science organization in the world also agrees. Every university also agrees. Maybe not Bob Jones. The fact is is that only a very tiny minority of scientists disagree with the overwhelming evidence. Frankly I have hard time believing that even those scientists signed such a ridiculous document.
