Global Land Surface Warming is not Uniform

May 6, 2014; 10:47 AM ET

The world as a whole has indeed warmed over the past 100 years, but new research from Florida State University shows that the warming hasn't happened everywhere at the same rate.

Using a newly developed analysis method, a team of climate researchers led by Zhaohua Wu, an assistant professor of meteorology at Florida State examined land surface temperature trends (minus Antarctica) going back to 1900.

Key excerpts from the Florida State 24/7 news report....

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."

Some areas south of the equator were found to have actually cooled between 1910-1980 before leveling out through the mid-1990's.
