California and the Southwest are entering the fourth year of drought conditions. This is what scientists call a normal drought that occurs naturally and only lasts a few years.

What is the cause of the drought and how will it have? Here & Now’s Robin Young speaks with co-author of the report, Benjamin Cook of the NASA Goddard Institute for Space Studies.
