New interactive map shows climate change everywhere in world

Summary: A geography professor has created a new interactive map that allows students or researchers to compare the climates of places anywhere in the world. The map draws on five decades of public meteorological data recorded from 50,000 international weather stations around the Earth. And it uses prediction models to display which parts of the globe will experience the most or least climate change in the next 50 years.

What does Salt Lake City have in common with Tehran? More than you might think, if you're a climate scientist.

University of Cincinnati geography professor Tomasz Stepinski created a new interactive map that allows students or researchers to compare the climates of places anywhere in the world. The map draws on five decades of public meteorological data recorded from 50,000 international weather stations around the Earth.

The data is mapped in a 4-square-kilometer grid that gives researchers a visual of what's happening with temperatures and precipitation from pole to pole.

"The map demonstrates climate change over time but also climate diversity. The concept is powerful and can inspire a lot of research," Stepinski said.

Stepinski has spent his career studying spatial, societal and temporal patterns in his Space Informatics Lab in the McMicken College of Arts and Sciences. His late map project in 2017 examined the racial diversity of every neighborhood in America. The digital magazine Quartz called the map "insanely detailed."

Stepinski, a native of Poland, has long been interested in climate and other natural phenomenon that are studied with statistics.

"I've lived in Houston, Tucson and Cincinnati. Climatically speaking, they couldn't be farther apart," he said.

For this project, Stepinski teamed up with Polish researcher Pawel Netzel, who worked in Stepinski's lab at UC. Using monthly records from the public database WorldClim, they developed a visual way for researchers to study patterns and variability of climate over time from locations virtually anywhere in the world.

The map, called ClimateEx, also allows researchers to study what areas of the globe have seen the most dramatic changes in climate over time. Not surprisingly, this includes portions of the warming arctic. But perhaps surprisingly the map also demonstrates that the tropics around the equator also have seen big changes. Stepinski said this is due not to variations in temperature but in monthly rainfall.

I wonder if there was an interval or time within the last several billions years when climate didn't change, both locally and globally?

If the answer is no, what are we discussing here?

Well, it changed radically around 65,000,000 years ago. But simple change isn't the problem.
