James Hansen @DrJamesEHansen published a new communications today titled “Reflections on Time Scales and Butterflies.” A link is below & my summary of the main points follows in this thread.

1/Xmailchi.mp/caa/reflection… June 2024 was the 13th consecutive record monthly global temperature. Comparisons with prior records shows the recent El Niño was not particularly strong.

Climate Scientists James Hansen @DrJamesEHansen, Leon Simons @LeonSimons8 et al have released a new communications titled ”The World Will Cool Off – A Bit – and Other Good News!”. Link is below and a summary follows in this 🧵

1/Xmailchi.mp/caa/the-world-… Hansen says recent article in The Hill by Jonathan Overpeck is misleading. It says if we start cooling soon then recent record temps can be ascribed to El Niño. Not true. World *will* start cooling due to La Niña but that doesn't mean unusual heating was all due to El Niño.

James Hansen (@DrJamesEHansen) released a white paper today titled “Global Warming Acceleration: Hope vs Hopium.” The following thread summarizes some of the key points.

Here is link to the paper:

James Hansen just publish a new newsletter titled “To Understand and Protect the Home Planet”.


Here is summary of the key points:
1/11mailchi.mp/caa/to-underst… His “Global Warming in the Pipeline” peer-reviewed paper will publish next week. It provides an alternative view of climate vs what the IPCC says. He's not criticizing IPCC researchers but rather the IPCC procedures & product & lack of needed advice to protect young people. 2/11

@DrJamesEHansen, @MakikoSato6, Reto Ruedy, @LeonSimons8 published an article titled “El Nino Fizzles. Planet Earth Sizzles. Why?”

It says we may have already passed the 1.5ºC warming *trend*!

I summarize the key points below. 1/

mailchi.mp/caa/el-nino-fi… September global temp was +1.7ºC relative to 1880-1920 or 0.5ºC more than previous record. But more important is that June-Sept was 0.44ºC more than same months in 2015 which was origin year for previous El Niño. 2/

James Hansen: "Improved knowledge of glacial-to-interglacial global temperature change implies that fast-feedback equilibrium climate sensitivity (ECS) is 1.2 ± 0.3°C (2σ) per W/m2."

ie, Our GHG emissions to date leads to 4.9ºC warming with only "fast feedbacks" considered! "Equilibrium global warming including slow feedbacks for today’s human-made greenhouse gas (GHG) climate forcing (4.1 W/m2) is 10°C, reduced to 8°C by today’s aerosols."

ie, with long-term feedbacks, we are committed to 10ºC of warming, or a bit less if we keep polluting.

I asked #ChatGPT4 to explain #ClimateChange in the voice of #Shakespeare. The result is quite extraordinary:
1/8 Prithee, attend, thou gentle souls and wise,
To hear a tale of warming in our skies,
A change that doth the very earth beset,
And causeth all in sundry ways to fret.
