While everyone is suffering from the Polar Vortex, it's the middle of January and the weather next week in Los Angeles will be in the mid-80s. This time of year, that might seem like a dream, but when summer rolls around, Los Angeles is sweating. Literally. According to a UCLA study, long hot summer days are expected to become the norm starting between 2041 and 2060. Los Angeles county will begin to have extremely hot days that are over 95 degrees way more often. In the San Fernando Valley and San Gabriel Valley, those long hot days will almost quadruple in frequency. At that point, we'll probably all be wishing for that tsunami to cool us down.
