Plus 2,5 graden van het oceaanwater in de RONI-index (Relative Oceanic Nino Index). Nog hogere anomalieën worden af en toe genoemd. Of het een sterke El Niño gaat worden of zelfs een Super-El-Niño van +3,5 - 4 graden..

Paul on a new physics analysis by #JamesHansen et al., how and why 2026 will be the hottest year (up to now)

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.

The Danger of “Reticence on Steroids”

In a candid December 2025 appearance on the program Climate Chat, climatologist James Hansen spoke plainly regarding the state of global climate communication. He described the scientific community’s current posture not merely as cautious, but as “scientific reticence on steroids”. Hansen argued that the persistent political narrative, that global warming can still be limited to 1.5°C via net-zero emissions by 2050, is “hogwash,” explicitly stating that such a figure “exposes too much” about the widening gap between official goals and physical reality. He noted greenhouse gas forcing is still increasing, making the 1.5°C target physically implausible without massive, immediate interventions that go far beyond current commitments.

This urgent warning serves as the catalyst for the deep-dive essay, Epistemic Reticence and the Structural Underestimation of Catastrophic Climate Risk. While Hansen sounds the alarm on the immediate data, the essay investigates the deep-seated structural and sociological reasons such warnings are routinely muffled. It explores the “Erring on the Side of Least Drama” (ESLD) hypothesis, which suggests scientists are culturally predisposed to downplay extreme risks to avoid accusations of alarmism. It examines how the IPCC’s requirement for consensus acts as a structural filter, often excising the “fat tails” of probability distributions, the very worst-case scenarios that Hansen warns we are ignoring.

If Hansen is right, and reticence has indeed gone too far, understanding the machinery of this silence is no longer just an academic exercise, it is a survival imperative. The essay attempts to dismantle that machinery to show exactly how and why we underestimate the risk of ruin.

"We scientists must share the blame, if we allow policymakers to believe that such scenarios provide a realistic projection of climate change...
...governments are under the corrupting thumb of special interests and give little weight to the interests of young people and future generations"
From #JamesHansen:
Warning! This “Colorful Chart” is Censored by IPCC
https://www.columbia.edu/~jeh1/

We already did cross #TippingPoints As of 2010, there was as much #CO2 in the air to cause at least 4°C #globalheating till end of the century. And since 2010 we were feeding further, exceeding amounts of #greenhousegases into the atmosphere. Also the heating is exponential. I refer to #JamesHansen. There is no bargaining and no compromise with physics.
And most important: Get fossil lobbyists out of #COP and #IPCC!
