For many places, the highest temperatures since record-keeping began have come in just the last 10 to 15 years. That’s the clearest possible sign that humans are altering the climate, said Randall Cerveny, a professor at Arizona State University.

Las Vegas recorded 120 degrees Fahrenheit (48.0 degrees Celsius) on Sunday for the first time in history. “It feels like the air is a blanket of just hotness that is enveloping you,” Cerveny said about that kind of heat. It’s life threatening and people are unprepared for it, he added. Here is a look at some of the records that have been broken around the world this year. Even one tenth of one degree above a previous record is a meaningful increase, and these records were all broken by at least seven times that amount.
