Addressing the Triple Planetary Crisis at Our Ocean 2025

Ocean Conservancy

As we prepare to participate in the 10 th Our Ocean Conference in Busan, Republic of Korea, from April 28-30, I like to think about this beautiful poem in a different way. Just like in the poem, the ocean remains largely undiscovered, unknown. Warmer ocean waters impact marine ecosystems, including coral reefs and fisheries.

What Is a Climate Model and How Does It Work?

Union of Concerned Scientists

Just by looking at the name, you can see that a GCM is a model that simulates the circulation of Earths different physical systems like the atmosphere and ocean. The Earths atmosphere and oceans create circulations in order to mix temperature differences between regions; GCMs, or climate models, simulate these circulations quite well.

WMO: Update on 2023/4 Anomalies

Real Climate

Other new studies At few other articles on this topic have also appeared recently: Allen and Merchant (2025) give a “new interpretation of the drivers of Earth’s energy budget changes and their links to ocean warming” Terhaar et al. 044002, 2025. Foster, "Global Warming has Accelerated Significantly", 2025.

Predicted Arctic sea ice trends over time

Real Climate

There is no real ambiguity in the observed trends, nor in the comparison (though extent is a little trickier than area to compare to), and so these discrepancies were very likely due to model failures – insufficient resolution to capture the polar sea ice dynamics, too simple sea ice physics, biases in the Arctic ocean simulations etc.

New study suggests the Atlantic overturning circulation AMOC “is on tipping course”

Real Climate

The paper results from a major computational effort, based on running a state-of-the-art climate model (the CESM model with horizontal resolution 1° for the ocean/sea ice and 2° for the atmosphere/land component) for 4,400 model years. Figure adapted from Caesar et al., Nature 2018.

Fights over geoengineering experiments will heat up in 2025

New Scientist

There is growing interest in exploring ways to counteract global warming by intervening in the atmosphere and the oceans, but planned trials are highly controversial
