It's too late and life as we know it is coming to an end.
The biggest impact will be population v food supply. This is already hitting parts of the World. This will lead to wars over resources, if not already happening. ME and people fighting over oil. Add the mass migration from the Third World to the First.
Food prices will rise and keep rising.
Devastation of natural land is causing the highest number of extinctions since the Mega Fauna era. That change was far slower. The loss of rainforest is affecting our climate.
As the mix of fresh and sea water and the rise in temperature changes the oceans, expect more floods on the coast, hurricanes and storms. Could this affect rainfall?
All this is happening slowly in our perception so we fail to really notice it. Which is why we all carry on as if it's not happening.
