Archimid, you have not provided one bit of evidence for your extraordinary claims. This is especially hilarious:
"4C over 100 years is worldwide destruction with only the small organisms surviving and patches of humans struggling to survive."
Considering that we have seen 10-15 C changes in midlatitude climate at the beginning and end of ice ages many times in the past one million years alone. And as we now know, these changes happened in a matter of DECADES. The Eocene had 14 C warmer average temps than now, and lo and behold there was life. So this statement of yours is really just hyperbole squared and goes against all evidence from the paleorecord.
also:
"Berlin will have Rome weather for a few weeks, then Siberian weather, for a few more weeks, then Saharan weather for a few more weeks, then it will have Caribbean weather for a few weeks, you name it, it will happen"
Utterly baseless, no model says anything like that will happen, and no paleorecord says it ever happened.
Last:
"Agriculture is already being disrupted by changes in seasonality and hydroligic cycles"
Also untrue. There is an overproduction of food globally, no disruption, no shortages.
Thing is, this is just a psychological phemonenon: people always love to imagine and fear a terrible all changing future that will cleanse the world of its sins. The Flood, the Last Judgement, you name it.
I agree that climate change is truly a huge danger and we need to deal with it quickly, but what you describe is utter unscientific nonsense
