There are a lot of fascinating changes. NASA describes the climate model:
To produce visualisations that show temperature and precipitation changes similar to those included in the IPCC report, the NASA Center for Climate Simulation calculated average temperature and precipitation changes from models that ran the four different emissions scenarios. The final products are visual representations of how much temperature and precipitation patterns would change through 2100 compared to the historical average from the end of the 20th century.
The video shows a scenario where carbon dioxide concentrations reach 670 parts per million by the time we hit 2100. We’re currently at 400 parts per million. [NASA]
