Climate models are the main tool scientists use to assess how much the Earths temperature will change given an increase in fossil fuel pollutants in the atmosphere. The atmosphere around us is an invisible fluid (at least to the human eye): we can apply math to that fluid to predict how it will look in the future.

Four RCP scenarios describe different levels of radiative forcing in the atmosphere by 2100. Radiative forcing is the change in energy balance in the Earths atmosphere due to heat trapping emissions.

The warming ocean is especially important. First, as we warm the ocean, this is creating a bigger temperature contrast with temperatures over the land when Arctic air plunges southward. Another factor is there is more evaporation from the land and ocean as the globe warms, so there is more water vapor in the atmosphere.
