Summary: New research shows the first detailed look at global land surface warming trends over the last 100 years, illustrating precisely when and where different areas of the world started to warm up or cool down. New research by a team of Florida State University scientists shows the first detailed look at global land surface warming trends over the last 100 years, illustrating precisely when and where different areas of the world started to warm up or cool down. The research indicates that the world is indeed getting warmer, but historical records show that it hasn't happened everywhere at the same rate. And that new information even took scientists by surprise. "Global warming was not as understood as we thought," said Zhaohua Wu, an assistant professor of meteorology at FSU. Wu led a team of climate researchers including Fei Ji, a visiting doctoral student at FSU's Center for Ocean-Atmospheric Prediction Studies (COAPS); Eric Chassignet, director of COAPS; and Jianping Huang, dean of the College of Atmospheric Sciences at Lanzhou University in China. The group, using an analysis method newly developed by Wu and his colleagues, examined land surface temperature trends from 1900 onward for the entire globe, minus Antarctica. Previous work by scientists on global warming could not provide information of non-uniform warming in space and time due to limitations of previous analysis methods in climate research. The research team found that noticeable warming first started around the regions circling the Arctic and subtropical regions in both hemispheres. But the largest accumulated warming to date is actually at the northern midlatitudes. They also found that in some areas of the world, cooling had actually occurred. "The global warming is not uniform," Chassignet said. "You have areas that have cooled and areas that have warmed." For example, from about 1910 to 1980, while the rest of the world was warming up, some areas south of the equator -- near the Andes -- were actually cooling down, and then had no change at all until the mid 1990s. Other areas near and south of the equator didn't see significant changes comparable to the rest of the world at all. The team's work is featured in the May 4 edition of the journal Nature Climate Change. The detailed picture of when and where the world has warmed or cooled will provide a greater context to global warming research overall, Wu said.

I am sick and tired of all the stupid arguments that humans have anything to do with global warming other than the fact they cut down forests and replace the areas with concrete and that is such a small percentage of the earth that the effect is insignificant. Even more ridiculous is the argument that an increase in CO2 causes global warming. CO2 is a trace gas and only about1 molecule per 3,000. Even if such a small amount could affect the temperture, it would be less than 1 tenth of one degree. Water vapor, not CO2 is earth's greenhouse gas. The fact is that the earth have been losing CO2 from the atmosphere for billions of years and is now CO2 starved. We would be far better off it we could double or triple the amount of CO2 in the atmosphers since that would aid plant growth which, if anything, would reduce global warming. 500 million years ago, CO2 levels were 20 times higher and the temperture was about the same. The problem is not global warming but the next ice age and ice ages last far longer (over 100,000 years) than warm periods lasting 15,000 to 20,000 years.
bittersweet, sharp-observations.

Americans who have no experience with, or knowledge of, tyranny believe that only terrorists will experience the unchecked power of the state. They will believe this until it happens to them, or their children, or their friends.

"If you love wealth more than liberty, the tranquility of servitude better than the animating contest of freedom, depart from us in peace. We ask not your counsel nor your arms. Crouch down and lick the hand that feeds you. May your chains rest lightly upon you and may posterity forget that you were our countrymen.”—Samuel Adams
