Global Warming?

Daytime Global Warming?

Today, May 15, 2014, in Los Angeles, California, it will be 99 degrees. Overnight, in L.A., it will go down to 68 degrees. That is a day/night temperature variance of more than 30 degrees. 99 during the day, 68 at night.

Thus, according to my scientific observation, in Los Angeles, global warming happens only during the day!
