The El Nino is off the charts. Can people see the real issue and accept the implications? We may be getting closer. See the Bigger Problem – mailchi.mp/caa/super-du... Also available on Substack: jimehansen.substack.com/p/super-dupe...

The race is on. The stakes are high. Understanding. Without that, why should anybody listen? See Beware Media Hype – mailchi.mp/caa/beware-m... Also available on Substack: jimehansen.substack.com/p/beware-med...

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.” See 2026 Experiment – tinyurl.com/3x9e6w3z Also available on Substack: tinyurl.com/2d7uv77e

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 Also available on Substack: tinyurl.com/33mtefsj

Sometimes the most complex problems have a straight-forward solution – let’s start gathering the evidence. See Exxon – mailchi.mp/caa/exxon Also available on Substack: jimehansen.substack.com/p/exxon

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-... Also available on Substack: jimehansen.substack.com/p/2026-on-tr...

Yes, we have an El Nino – probably Super-Duper – see the better diagnostic (Fig. 2) – comparison to ordinary and Super El Ninos See Super-Duper El Nino: mailchi.mp/caa/super-du... Also available on Substack: jimehansen.substack.com/p/super-dupe...

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. tinyurl.com/2kj82pwa

El Nino strength is important, but the extraordinary, accelerating, warming of global sea surface temperatures is much more important. See Super El Nino? – mailchi.mp/caa/super-el... Also available on Substack: jimehansen.substack.com/p/super-el-n...

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-... Also available on Substack: jimehansen.substack.com/p/runaway-cl...

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 Also available on Substack: tiny.cc/cf6z001

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.

The chaos in government today has potential to seed huge gains a few years from now; more on that later. For now we must stem disastrous ideas. See Fix Our Forests Fiasco – mailchi.mp/caa/fix-our-... Also available on Substack: jimehansen.substack.com/p/fix-our-fo...

It’s asking a lot to expect young people to understand the real climate story. I’m thrilled to learn that many of them may be open-minded mavericks. – mailchi.mp/caa/mavericks Also available on Substack: jimehansen.substack.com/p/mavericks
