The future trajectories are based on different scenarios, such as versions of the future where the world comes together to take action and phase out fossil fuels, or versions where fossil fuel production continues throughout this century. What causes sea level rise to persist for centuries?

In a new study released today, UCS attributes substantial temperature and sea level rise to emissions traced to the largest fossil fuel producers and cement manufacturers. Every delay in phasing out fossil fuels will burden future generations who need to adapt to rising seas and recover from loss and damage due to sea level impacts.

Quickly and sharply tapering down the use of fossil fuels, which are the main driver of human-caused climate change, is just as crucial if we are to have any chance of keeping climate extremes from spiraling further out of control. Uncontrolled fires are also burning in Greece. That can and must change NOW.

That 2013 headline resulted from the first effort to quantify emissions from the ‘carbon majors’ —fossil fuel companies and cement manufacturers whose businesses have contributed an outsized amount of heat-trapping gases to the atmosphere.

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.
