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

And then I misspelled Cal's nickname (The Big Dumper) and none of my young coauthors caught it -- are there no baseball fans among young people?

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.

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

This issue is the potential catastrophic consequences, if we let the ice shelves melt to the point that the West Antarctic ice sheet collapses -- increased snowfall is negligible by comparison.

The ocean warming is causing ice shelves to melt, but, as you know from the ice cubes in your drink, melting of ice in the ocean has no effect on sea level. Small ongoing sea level changes, whichever direction, have modest impact.

I have not had time to look at data, but such a result is possible temporarily. Accelerated global warming is causing increased snowfall over ice sheets, especially Antarctica -- and this shows up as at least intermittent ice sheet mass gain in gravity satellite data.

Chapter 10. The Venus Syndrome & Runaway Climate James Hansen

Draft Chapter 10 of Sophie’s Planet, Venus Syndrome & Runaway Climate (mailchi.mp/caa/chapter-...) is an introduction (also available on Substack: jimehansen.substack.com/p/chapter-10...). Quantitative analysis with insights on climate physics will follow.

We, and young people, need help from people who understand the essence of climate science. See Forest versus Trees - columbia.edu/~jeh1/mailin... or its abbreviation - mailchi.mp/caa/seeing-t... also available on my Substack - jimehansen.substack.com/p/seeing-the...
