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.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
