Not that there are no worries, but the worst case scenarios being put forward are almost certainly not accurate. In fact it has been acknowledged that the worst case models submitted to the Paris Climate Accord talks were misleading in their assumptions.
yup. There was one published study that basically says that if they are right which is not proven then the worst case scenario is slightly less probable.
But Paris Climate Accord are now dated, 2017 report from IPCC says the 2°C objective has already failed and we're heading for a 3 to 5°C average global temperature increase whatever we do by the end of the century, such a global average increase translate into a 6 to 10°C average continental temperature increase. With a 6 to 10°C temperature increase no known agriculture is possible.
