Apocalypse now: Combined impacts of rising temperatures, dwindling food supplies and biodiversity loss could trigger 'global systemic collapse', scientists warn
There is not an ounce of sense in this. A warmer planet would produce MORE food. A warmer planet would make vast new areas of Northern Canada and Siberia available to grow crops. And crops everywhere would grow better with more CO2 in the atmosphere
And warm climates have MORE biodiversity. Life just leaps out at you in the tropics. Warmth is the last thing that would be bad for biodiversity
And there would be MORE rain, not "dwindling sources of fresh water". The earth's surface is two thirds water and warmer oceans would evaporate off more water vapour -- which is where rain comes fro.
It is so tedious that I have to keep repeating the obvious. These people are just con-men who are ignoring the most basic physics
