If you've been enjoying the extremely dry, hot, uncomfortable weather we've been having here in Southern California, then good news: We could be having more of it — like several decades more of it.

The odds of experiencing future megadroughts in the Southwest are pretty high, according to a new study by Cornell, University of Arizona and U.S. Geological Survey researchers.

Toby Ault is a professor of earth and atmospheric sciences at Cornell University and lead author on the paper, and he joins A Martinez on the line to talk about why, even if we experience El Niño this year, it probably won't make much of a dent.
