    Better think again my AGW friends. This little California drought is nothing put into historical perspective.


    Collapse 7. The Ancestral Puebloan (Anasazi) culture in the Southwest U.S. in the 11th - 12th centuries AD. Beginning in 1150 AD, North America experienced a 300-year drought called the Great Drought. This drought has often been cited as a primary cause of the collapse of the ancestral Puebloan (formally called Anasazi) civilization in the Southwest U.S., and abandonment of places like the Cliff Palace at Mesa Verde National Park in Colorado. The Mississippian culture, a mound-building Native American civilization that flourished in what is now the Midwestern, Eastern, and Southeastern United States, also collapsed at this time.

    None of the claims of more wildfires, more hurricanes, more droughts, more torndoes, etc due to global warming has any credence. Roger Pielke Jr. shows this by data and IPCC AR's in his book "The Rightful Place of Science: Disasters and Climate Change".

    For example on droughts:

    Just piling on here, but it's worth doing. It was worse back then . . .
    New Study: Western North America Was Much Warmer And Drier With Peak Wildfire Rates When CO2 Was 265ppm
    By Kenneth Richard on 12. November 2020

    The southwestern US was nearly a desert from about 9000 to 5000 years ago, when Holocene peaks in aridity, surface temperature, and wildfire rates occurred. Arctic sea ice was at its lowest extent of the Holocene during these years.

    A new extensively-referenced study (Lachniet et al., 2020) reviewing many dozens of climate records from across western North America has determined there is nothing unprecedented or even unusual about the modern climate for this region.

    And the possibility that drought led to the collapse of multiple societies is comforting how?

    Not comforting just reality. Learn to face it instead of fear it.

    This 300 year drought corresponds to the global cooling period after the Medieval Warm Period.

    There's no reason to think it is worse now, or will get worse.

    The name "California" means "hot oven".

    An apt name for what the Spanish discovered there in the 1700s.

    (or at least this is one possible historical interpretation; there are other possible etymologies of the name)

    Yes. Global warming will result in greater levels of global precipitation.

    Right. That is as certain as anything in empirical science, and is a major reason periods of warm global climate were called, "optimums" before that term was ruled politically incorrect.

    It’s odd how many people think that warming will result in desertification. It will actually result in more rain forest lands and a general “greening” of the globe.

    Not when that is the constant chant of the media.
    Right. But the global greening effect of atmospheric CO2 fertilization is of course far greater, especially in water-stressed environments, than its modest effect through increased temperature, rainfall, and growing season length.
