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

Union of Concerned Scientists

Sea levels are rising, and science shows they will continue to rise for generations due to heat-trapping emissions that have already been released. This highlights a profound and enduring climate injustice: future generations will face the consequences of todays decisions. What do we know about future sea level rise?

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. The Earth’s climate system does not like imbalances in heat!

It shows the atmospheric concentrations of carbon dioxide (CO 2 ) and tells a story about the carbon cycle, involving Earth’s crust, the atmosphere, land surface, the biosphere, and the oceans. The Keeling curve, highlighted with the release of important climate reports and climate summits.

How Do ‘Future Climate Scenarios’ Shape Climate Science and Inform Policy? 

Union of Concerned Scientists

Climate models and climate impact studies use emission scenariosestimates of potential future changes in heat-trapping emissionsto help us see how choices made about emissions today can shape tomorrows climate. Four RCP scenarios describe different levels of radiative forcing in the atmosphere by 2100.

Dr. Shaina Sadai Talks About COP27, Climate Justice, Sea Level Rise, and Corporate Accountability

Union of Concerned Scientists

Through greenwashing ads, disinformation campaigns, attacks on scientists, and production of fake scientific evidence, the industry has engaged the playbook of deception to undermine climate action. UCS’s new Hitz Family Climate fellow, Dr. Shaina Sadai , is stepping into this emerging area of work.

AR6 of the best

Real Climate

As climate scientists we tend to look at the IPCC reports a little differently than the general public might. Here are a few things that mark this report out from previous versions that relate to issues we’ve discussed here before: Extreme events are increasingly connected to climate (duh!) Figure SPM 8. Johnson, A.

Deciphering the ‘SPM AR6 WG1’ code

Another clue indicating a shortcoming is if you look at the atmospheric CO 2 -concentrations over time to see how much impact the IPCC reports have had on the real policy-makers in the world (Figure below). The cause of our changing climate is the increase in atmospheric greenhouse gas concentrations that we have released into the air.
