I've read several articles indicating that a variety of indicators suggest the SouthWest is in a Mega-Drought phase comparable to the one that moved the Anasazi--or that was the most likely hypothesis--out of the Arizona/New Mexico areas. I haven't seen a comparative study to my Okie Granddad's Dust Bowl but that seems to have lasted considerably shorter.

The link is a readable summary, but the original scientific study is linked inside, for those of you who want the original source.
I'm not sure how much of the Tahoe area forest will remain in 30 years, given the shift to less moisture and more heat (if the shift continues, as studies suggest it will), but I guess I hope to live long enough to see. My wife and I frequently hike parts of the Tahoe Rim Trail and part of the PCT.
Obviously if the trend continues it poses even more challenges to the urban centers in the SW like Phoenix, Vegas, LA, Reno & Nevada (where I live), etc, and Northern Mexico.
My oldest son's employer/winery has bought vinyards out of their traditional base in the Cali Central Valley up into Oregon and Washington (and New Zealand)--I won't say due to climate change, but he tells me that is largely why-- but the last 4 years have reinforced that not even this may be a safe hedge since the bulk of their production is in the Central Valley and areas close in OR/WA have burned anyway. Luckily most of the grapes this year are harvested or close to mature, so the smoke may not effect their production this year much, except for the vinyards that burned and the fact that the heat for the last two months has been ultra-intense, even for the Central Valley.
Muir: Part of the rationale for selling the Colorado cabin (in the South Central area) was provoked by the above, although it had more to do with wanting to retire to Reno and unsure of whether there were enough funds to suipport two places. Reno apparently has warmed 5 degrees over the last 80 years, so we may have jumped from the frying pan into the fire.
