Everyone knows the weather in the Bay Area can't be beat. But climate scientists say that's going to change, perhaps sooner than we think. 

The number of days with temperatures above 90 degrees is going to soar in certain parts of the region by the middle of this century, according to a new study from the Union of Concerned Scientists published in the journal Environmental Research.

San Jose averages seven days a year with temperatures above 90 degrees Fahrenheit, but that number's expected to jump to 24 days by mid-century.

San Francisco, which averages just two days of temperatures over 90 per year, can expect to experience 10 of these days per year by mid-century, according to the study. 

The Union of Concerned Scientists has an interactive tool on its website to check out how cites will fare in the future.

"Now we're going outside of the realm of conditions previously experienced," said Dr. Kevin Trenberth, a scientist with the National Center for Atmospheric Research. "That's when the damage really becomes extreme and we get all of these wildfires. The odds are changing for these to occur, with climate change, with the global warming from the human influences on climate."
