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.

Rapid ocean warming is emerging as a critical driver of global climate instability, influencing weather patterns, ecosystems, and long-term environmental resilience.

In the latest video, Egon Cholakian explores the underlying mechanisms behind this acceleration and why it demands urgent scientific and policy attention.

Climate ‘fingerprints’ mark human activity from the top of the atmosphere to the bottom of the ocean | The-14

Climate fingerprints from atmosphere to ocean depths show human-caused warming, confirming greenhouse gas emissions as the main driver of global change.

Will 2026 push coral reefs past a tipping point? After mass bleaching and rising El Niños, scientists warn many reefs may not recover in time.

Warmer ocean currents significantly destabilize ice sheets, driving their retreat

New research reveals how #OceanWarming triggered the large-scale retreat of the Northeast #Greenland Ice Stream (#NEGIS)—offering vital clues for understanding its modern-day vulnerability.

NEGIS is the largest ice stream draining the Greenland Ice Sheet into the #ocean. It contains enough ice to raise global sea level by 1.1–1.4 meters. Its stability is therefore critical for future sea-level projections.

☁️ 🌍 Cloud alert!
Warming oceans = fewer marine stratocumulus clouds → less sunlight reflected → more warming. Spotlighted in a new #EUMETSAT case study.
These subtle clouds play a huge role in our climate system — but they’re tricky to model.

Check out the full case study here 👉 https://user.eumetsat.int/resources/case-studies/global-warming-speeds-up-as-warmer-oceans-reduce-marine-cloud-cover

Let’s keep pushing the boundaries of climate science — better data, smarter models, broader impact.

Wytwarza 1/3 tlenu na Ziemi. Jeden z najmniejszych znanych organizmów zagrożony

Zmiany klimatu mogą wywrócić do góry nogami życie w oceanach. Mikroskopijne bakterie, które są podstawą morskiego łańcucha pokarmowego, zaczynają znikać z tropikalnych wód. Prochlorococcus to bakterie z grupy sinic, osiągające wielkość do 1 mikrometra. W przyrodzie odgrywają bardzo istotną rolę. Choć są najmniejszymi organizmami fotosyntetyzującymi, wytwarzają aż 1/3 tlenu na Ziemi – i to zarówno […]
