Man made global warming is a fact.
You need to pass college courses, Physics 1, chemistry 2 and Geology 1 to understand why CO2 causes global warming and you also need about 10 years study under a professional PhD level meteorologist. I was an "AGW Denier" before 2008, but by then I had learned enough real science to prove myself wrong.
IF you are not at least an amateur meteorologist you really are not educated enough to make a comment on Climate Change.
You might wonder why there are predictions by climatologists which at first glance seem to be contradictions. They say rainfall will increase but so will droughts. How does that make sense? Simple. If the temperature rises on land twice as fast as it does over water, then the water from rainfall evaporates twice as fast instead of soaking into the soil.
The megadrought in California is most likely not going to end any time soon. It could go on for centuries as global warming gets worse and worse. IN a few weeks they will need to start rationing electricity in CAlifornia and other western states as the water behind the dams is getting too low to produce electricity. IN 6 months to a year or two the drought will become a FAMINE and people in the United States will begin to starve to death.
There are megadroughts on-going in Europe Africa and Asia presently too. The Danube and a major river in China are drying up for the first time in a 100 years or more. The last time a famine hit China 60 million people starved to death. That could happen right in the United States this time around too. If a major famine hit both the U. S and China simultaneously, the casualties world wide could exceed a hundred million before the famnie stops.
Let' shope things don't get that bad, but I'm just warning you in terms of geologic record, climate disasters tend to snowball out of control when they happen.
When the permafrost in Canda and Russia and Europe melts it will release even more CO2 and Methan e intot the atmorphere all at once. Far more than humans have ever produced combined all at once. We call ths a "Methane Bomb"l Last time this happened on Earht 90% of all species on the planet went extinct,
so we know exactly what the results will be if and when this happens again. If we do not stop ALL net polluting by 2050 it WILL happen again afew centuries later.
