James Hansen: With Strong El Niño, 2026 is on Track to be Warmest Year ever, to be Surpassed in 2027
In this video I chat about the new article that James Hansen and his colleagues just posted regarding their prediction on 2026 being the warmest year ever, to be surpassed by an even warmer 2027.
Of vital importance is the Earth Climate Sensitivity for a doubling of CO2, which Hansen argues is 4 to 5 degrees Celsius for a doubling, and is therefore much higher than the IPCC value of 3 degrees C. Hansen argues that the IPCC number is wrong with 99% certainty, mainly due to handling the forcing from the aerosol indirect effect on low level clouds.
Hansen importantly argues on 4 independent lines of evidence supporting the 4-5 C per doubling of CO2 climate sensitivity.
These include:
1) Proper accounting for aerosol forcings, leading to a proper value of climate sensitivity, arguing that the IPCC has got both numbers wrong in their models and assumptions.
2) comparisons of temperatures at the peak of the last ice age 20,000 odd years ago with pre-industrial temperatures being greater due to last ice age temperatures being 6 to 7 degrees C cooler versus the previously thought 4 degrees Celsius colder
3) comparisons of temperatures during Snowball Earth 600 million years ago to todays temperatures
4) global warming temperature data over the last 200 years
I am over 99% certain that Hansen is correct, and that over the next year or so this will become increasingly obvious as Earth global warming continues to accelerate to record levels.

Abstract
Projections of near-term climate change are a potential research tool. However, for that tool to be most useful, the physical basis for a prediction must be made clear. The basis for our projection of record 2026 global temperature is high climate sensitivity, with its implication that aerosol cooling was still increasing during the period 1970-2005. One consequence, global sea surface warming, already has important effects. Causes of climate change must be understood for policy purposes. Figures in this post and our recent papers are continually updated on our website.
