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. SSP5: Taking the highway A scenario driven by economic growth and high fossil fuel use, leading to rapid warming.

The primary cause of accelerating sea level rise is human activity As people burn fossil fuels and emit heat-trapping gases like carbon dioxide, our atmosphere and our oceans warm up. As the ocean warms, it expands. That adds water to the oceans, which raises their level.
