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.

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.
This research was published in Nature Climate Change.
The string of record high monthly temperatures continues and then some.
Highest, global monthly temperature anomaly on record was set last month.

New research shows that recent global climate trends have caused widespread increases in both plant growth and evaporation over the past 32 years, especially during periodic drought cycles that are linked to strong El Nino events.
Global surface temperature records keep falling.
September 2015 ended up as the second warmest September on record globally for land/ocean surface combined, according to NASA GISS.
