There's a really fantastic Youtube based weekly show I watch, called TMRO. Mostly space news, launches, new satellites, technology advances, stuff like that. Every now and then they drift into lefty globularwarmism and they did it this week, talking about the Atacama desert as an analog for some elements of the Martian surface. Talking about the only life present there, being about 18 varieties of microbes that are such extremophiles that they can only exist in Atacama under its current static conditions (i.e. no precipitation, ever). They went on to say that due to globularwarmism, it rained in the desert and that a dozen of these microbes went extinct because they are so specially evolved to absorb moisture from any available source, they ruptured their cell membranes due to the excessive water from the rain.
...Except they also said it hadn't rained in Atacama for 500 years.
So did globularwarmism cause it to rain 500 years ago? No explanation of the source of rain in that area 500 years past. Or if the asserted man-originated globularwarmism is responsible for an increase in precipitation there consistently.
If a freak storm can happen 500 years ago, it can happen today too.
