Climate change is hard to imagine, especially 60 years in the future. With that in mind, environmental scientists have developed a web-based application that can tell people living in one of the 540 cities in Canada or the continental United States how their homes will be transformed by the year 2080, and in what city of today is more It is likely to look like.

Using 27 different climate models, the researchers badyzed 12 different aspects of climate, including maximum and minimum temperatures, precipitation and how those factors vary with the seasons, for each location in two scenarios: one in which atmospheric concentrations of dioxide carbon (COtwo) increases from 410 parts per million (ppm) today to approximately 650 ppm in the year 2100, and another in which the COtwo the levels increase to around 1370 ppm. Then, they compared the projected data points of each city with the climates that those places experience now.

In the lowest emission scenario, approximately 70% of cities have a "sister city of future climate," but they are usually hundreds of kilometers away and further south, researchers report today. Communications of nature. For example, residents of Washington, DC, can expect a climate in the 2080s that resembles the current climate in Paragould, Arkansas, about 132 kilometers northwest of Memphis, Tennessee. Meanwhile, people in Anchorage, Alaska, may experience the same climate as the current Owen Sound, Canada, about 160 kilometers northwest of Toronto.

But in the scenario of high emissions, only 17% of places will have sister cities; The researchers point out that an incredible 83% will have a future combination of temperature and precipitation unlike anywhere in the western hemisphere north of the equator.

Do you feel a little hot under the neck? If you want to know what the weather will be like in your city in the 2080s, the application is available here.
