Our publisher prefers that we not send out more draft chapters of SP, but we must remember our friend Rafe, a big, gregarious, warmhearted fellow, who fought for the future of young people and future generations. See Pomerance– tinyurl.com/3rxh7w6v

The Nino index (Nino3.4) has just reached neutral, but global SST has matched the highest level for this date, which was achieved during the last El Nino. Super warming is clear. U of Maine Climate Change Institute has a spectacular interactive graphic that they update daily.

Sometimes the most complex problems have a straight-forward solution – let’s start gathering the evidence.

El Nino strength is important, but the extraordinary, accelerating, warming of global sea surface temperatures is much more important.

Yes, we project that 2026 will be the warmest year. If others will provide the physical basis for their projections, we have an
opportunity to learn something from this natural “experiment.”

Yes, we have an El Nino – probably Super-Duper – see the better diagnostic (Fig. 2) – comparison to ordinary and Super El Ninos

A physics-based analysis concludes that this year will be the warmest, not second warmest. In any case, we can learn something about climate change. See 2026 On Track for Warmest Year – mailchi.mp/caa/2026-on-...

There is a limit on how far we can let climate run away now, if we are to give the next generation an opportunity. See Runaway – mailchi.mp/caa/runaway-...

Science-based policies could successfully limit human-caused climate change, but when political parties are allowed to accept money from special interests, policies are distorted to the point of being ineffective. See Politics: tiny.cc/9f6z001

The presumed upcoming El Nino will help cement and quantify global warming acceleration, showing that 2C global warming is likely to be reached in the 2030s, not at midcentury.
