First, what it means for the poorest and most vulnerable people in the world. These people have contributed little to the problem, and yet are impacted first and worst by climate change.
A world that is 1.5 degrees warmer would be a hard place for them. But in a world that is 2 degrees warmer, hundreds of millions more people will be affected: facing water shortages, food insecurity, or even displacement. The ability for people to access water goes down as the planet warms. So does food availability, because of impacts on crops, livestock, and fish populations.
