The resulting weather disasters are severely stressing a society constructed for the old, somewhat calmer climate of the 20th century. Of course, the El Nino is no guarantee that an SSW will occur, but it is more likely to produce one, based on historical data. Find out more about our newsletters here. There are alternative ways of lowering temperatures inside buildings, she says: You can replace the roof with a more reflective roof, and it will reduce the local urban heat island temperature. In a 2019 study, she and a colleague estimated that this could reduce deaths in an urban heat island area during a heat wave by 25 percent. Because tornado formation depends on a complex set of ingredients in and around a single thunderstorm, there is no sign that climate change is tending to make tornadoes stronger or weaker on average.
