Paul Beckwith, a climate science educator, goes through James Hansen's recent warnings about a coming "Super El Niño".

This video (24:48) assumes a small amount of background in math and science, enough to read time/temperature graphs, but is generally quite accessible in its explanations. He walks through a lot of good stuff like how the El Niño / La Niña cycle works, what some of the "forcings" are that are driving some of these things, why things like aerosols matter, what different models show, what the consensus predictions have been and why Hansen's predicting something substantively stronger.

It's a pretty worrisome set of things, but Hansen has been an important voice in the climate conversation, and I think Beckwith's presentation is pretty level—trying to just walk through the information dispassionately in a way that can help you understand the science part.

In biology/geology "#marinesnow" refers to the #organicdebris of organisms from higher #waterlevels. The #carboncycle thus transfers #CO2 to the #seabed, thus binding the #greenhousegas.
B. Borer et al. (2026) found that #microbial components of this "snow" induce #calciumcarbonate #dissolution in higher waters, reducing their #settlingvelocity and requiring consideration in future #climatemodels.

This interesting #study is based on ancient lake #sediment #analyses from the #Bogotá #Basin. It proves that the existing #climatemodels about the #Pliocene were underestimated regardung tropical regions. This allows prognoses, according to which also the global warming of today may bring more heat in some #tropicalzones than expected.

You know, the Climate Skeptics got it partly right. But they missed the fact that the situation is worse than predicted. The #ClimateModels haven't really understood the complex, interacting impacts of the #ClimateCrisis. They are worse and more diverse and happening faster than expected. For example:

🌍 We are glad to have hosted Abdou Aziz Coly, #PhD candidate from Université Gaston Berger, at #MPIM!

Through the @maxplanckgesellschaft ARTEMIS mentoring program, Abdou has been mentored by our scientist Romain Fiévet. They have been working together on tropical convection & #ClimateModels with locally refined grids. 🤝

This week, Abdou and Romain are attending the MPG-wide ARTEMIS #workshop in Heidelberg connecting with other #mentoring teams across the network. Great collaborations ahead!
