Looking Back at the Colorado River Pilot Project Cloud Seeding Experiment

I know the millions of you out there have been wondering WHAT have I been doing to be so unproductive at this website for so long. Well, I was being productive in the PEER-REVIEWED literature!  Last July, the article appeared in the American Meteorological Society journal titled, “Weather, Climate, and Society.”  Prof. Dave Schultz, U. of Manchester, England,  my co-author is also the author of the book, “Eloquent Science” and a highly regarded atmospheric scientist.

The article:

After it FINALLY (story on that some other time) “got  in” to a different journal than the one we started with, I got a request to write a shorter, more accessible version by someone I greatly admire,  Dr. Judith Curry (former chair, Atmospheric Sciences at Georgia Tech). That plain language, more candid version appeared on her website, Climate etc. not long afterwards.   I recommend Curry’s 2023 book for an even handed view of the climate problem, “Climate Uncertainty and Risk.”

The plain language version:

It then appeared on another widely viewed website, What’s Up With That, always worth reading, right away.  That was a big surprise.

Now it’s spread to several other websites!  It is amazing to me that such an old story, but one that’s not such great a science one,  could draw so much attention today.  ALR
