Barring a miracle, the average temperature of the Earth is going to rise somewhere between 2°and 5° C above pre-industrial levels by the end of the 21st Century.  The planet will be ravaged by storms, wildfires, droughts, and the loss of land masses to sea-level rise.

What we do to mitigate climate change here and now has a profound effect on the outcome.

We’ve been warned.
