The world will not end because of climate change. The world will be fine, it's HUMANITY that will be in danger.
Yes, but we won't be extinct in 12 years due to it.
The climate will continue to get worse the longer we add more greenhouse gases to the atmosphere via artificial processes. But the world will still exist in 12 years. And so will civilization and life as it is now, barring an asteroid collision or cosmic radiation or supervolcano or man-made supervirus or nuclear war.
I never said that we would be extinct in 12 years.
