How We Know that Global Warming is Accelerating and that the Goal of the Paris Agreement is Dead

In the past we too were able to adapt. The inuits, Native Americans, and also most other tribes around the world were able to move as the climate changed, on to more suitable areas to farm, hunt or graze. 

The Native Americans of South America moved many times over the course of hundreds of years, mostly northwards towards the Yukatan as the "dry line" shifted during that period. 

We have lost that ability, we have country borders, cities, over population, and all sorts of reasons now which means we can no longer adapt so easily to any changes in the climate where we can leave those areas which become inhabitable and move to better areas. 

Climate change itself is not a problem for the Earth, it can change hugely and it will still be here, and life will go on albeit perhaps in different forms. For humans though it is a big issue, and we do have to learn to adapt. But humans are funny, they hate change and they are now too slow to adapt, too comfy in their modern luxury. 

Oh yes, there's no way we can plausibly wipe out all life on Earth. But we could certainly wipe out the crops and key domesticated species that support us, and massively reduce our own liveable range.

I also don't think climate change is even a human extinction issue - there's no way we'll all be wiped out. But I think it's very likely that global warming near 3C or higher would have catastrophic consequences for human civilisation.
