It's getting hot in here, so take off all your non-essential items of clothing.
According to a new UCLA climate study, average temperatures are going to rise in Santa Ana and Long Beach by nearly four degrees.
But you still have time to stock up on sunscreen.
"Mid-Century Warming in the Los Angeles Region," the new study led by UCLA climate expert Alex Hall, shows temperatures throughout that chunk of Southern California will rise by an average of 4 to 5 degrees Fahrenheit by 2050.
Santa Ana, at 3.85 degrees, and Long Beach, with its 3.82 spike, are actually on the cooler side of the spectrum.

But, overall, the increases are expected to triple the number of extremely hot days in dense urban centers and quadruple them in desert valleys and higher elevations like Big Bear, Lancaster and Palm Springs.
It will be warmer everywhere, the changes will be significant and though the numbers are pretty much irreversible despite current or future global warming strategies, at least the region can plan now for what is to come, notes Hall, an associate professor in UCLA's Department of Atmospheric and Oceanic Sciences and a lead author on the Intergovernmental Panel on Climate Change reports the United Nations relies upon.
This is the first of five studies Hall and his team are conducting on regional climate change, with future reports coming on local rainfall, coastal fog, Santa Ana winds and soil moisture, run-off and evaporation.
