Thank you, thank you, Mr. Borass.   A number of people have predicted for decades that climate disruption would cause massive, unprecedented migrations of people as their arable land and/or water disappeared.   It is certainly part of the refugee situation in Europe at this time.  Parts of India are becoming uninhabitable at least for some of the summer.   This year saw the highest temperature ever recorded outside of Death Valley, when India had temps of 129F.  They don't have air conditioning.  The drought is causing many farmers to commit suicide.   Others are becoming climate refugees.    

Lake Mead is at a record low for the second year in a row.    California is losing billions of dollars in crops because they can't water them.  There are hundreds of people in the San Joaquin valley whose wells no longer provide water, because the water level has dropped so dramatically.    

This is not going away, but it will get worse.
