Another silly prophecy
"US faces mega-drought future: Global warming will cause the worst dry spells in more than 1,000 years". You wonder why anybody takes any notice of such Warmist prophecies now that none have so far succeeded and many have clearly failed. And this prophecy ignores basic science anyway. Warmer oceans would give off more evaporation, which falls as rain. So a warmer world would be WETTER, not drier
The western US will face increasingly severe mega-droughts later this century if no action is taken to curb climate change, researchers have warned.
They say that 'unprecedented drought conditions' - the worst in more than 1,000 years - are likely to come to the Southwest and Central Plains after 2050 and persist because of global warming.
It is the first study to predict that the coming intense dry spells could exceed the decades-long mega-droughts that occurred centuries ago and are blamed for the demise of certain civilisations in the late 13th century.
'Nearly every year is going to be dry toward the end of the 21st century compared to what we think of as normal conditions now,' said study lead author Dr Benjamin Cook, a Nasa atmospheric scientist. 'We're going to have to think about a much drier future in western North America.'
According to the study, published in the journal Science Advances, there is a more than 80 per cent chance that much of central and the western US will have a mega-drought lasting at least 35 years later this century.
Since the year 2000, seven western states in the US has seen their driest periods in centuries. [Indicating that the climate where the rain forms has been COOLER!]
These states are Arizona, California, Colorado, Nevada, New Mexico, Utah and Wyoming
And scientists in California have warned that the region may be experiencing a century-long 'mega-drought'.
The warnings came after sediment studies showed California is currently experiencing the driest spell since 1580, and that the regular rainfall seen during the last century is likely to have been a temporary deviation in a cycle of droughts and very occasional rainfall over the last 3,000 years.
In 2013, California received less rain than in any year since its formation as a state in 1850.
However droughts lasting more than 100 years are far from unheard of in the state.
Looking back over several thousand years, droughts have been known to last over a decade, and in some cases they can last a century.
And the patterns tend to repeat, meaning another drought of this length will probably happen again in the future. [From natural causes]
