Why Climate Scientists Are Sounding the Alarm on the Ocean Circulation System AMOC

Union of Concerned Scientists

Last month, 44 climate scientists from 15 countries wrote an open letter to the Nordic Council of Ministers highlighting the risk of a potential collapse of the Atlantic Meridional Overturning Circulation (AMOC), a critical ocean current system in the Atlantic Ocean. But what exactly would cause the AMOC to collapse?

​​The Science Behind Sea Level Rise: How Past Emissions Will Shape Our Future

Union of Concerned Scientists

Because of the way the climate and ocean systems respond to heat-trapping emissions, sea levels will continue to rise even after air temperatures stabilize. Research with climate models in recent years shows that when carbon dioxide emissions stop, the rise in atmospheric temperatures will likely also stop.

Net Zero/Not Zero

Real Climate

With empirical data and more and better modeling, it has become clear that, to first approximation, the eventual anthropogenic warming from carbon dioxide is tied to the cumulative emissions. This figure is from the AR6 SPM: The relationship between cumulative carbon emissions and temperature (SPM AR6).

Developing Model Federal Legislation to Advance Safe and Responsible Ocean Carbon Dioxide Removal Research in the United States

Law Columbia

The Sabin Center today published model federal legislation to advance safe and responsible ocean carbon dioxide removal (CDR) research in U.S. Controlled field trials and other in-ocean research is critical to improve scientific and societal understanding of CDR techniques that could help the U.S. reach its climate goals.
