Last month James Hansen sent to his mailing list  To Understand and Protect the Home Planet .  He said this effort will be published with several colleagues as co-authors in  Oxford Open Climate Change  as  Global Warming in the Pipeline .  The  New York Times  reported on this paper yesterday by David Wallace-Wells. He called Hansen the Godfather of Climate Science. In 1988 Hansen appeared before a U.S. Senate committee, beginning the era for climate alarm. Actually, I worked for the Senate Energy and Natural Resources Committee from 1979-1982, and  Professor David J. Rose  of MIT presented a view about climate warming, which was totally ignored.  Wow, that was more than 40 years ago.  He soon thereafter retired and moved to Honolulu, where we had long discussions on the seriousness of this phenomenon.  Thus, when Hansen suddenly made headlines in the later 1980's I met with him to discuss solutions.  I had a few geoengineering thoughts.  There was a sense that the world needed to

Yesterday,  Time  magazine said that Elon Musk's  Starship crash was no big deal .  Today:   There's No Way to Make Space Travel Good for Planet Earth Right Now .   SpaceX has bragged about their Falcon 9 rocket:  217 launches, with 61 in 2022 alone. The problem is that the Falcon 9 uses oxygen and fossil fuels, creating black soot injected directly into the stratosphere ( 7.5 miles to 31 miles high ).  This soot lingers for 5 years, absorbing heat, damaging the ozone layer and contributing to climate change. Of course, they are not alone, for there were 180 global rocket launches last year, and this will only get worse. Mind you, the aviation industry contributes 100 times more, but the difference is that airplanes fly only up to 6.6 miles, and the pollutants precipitate out the the atmosphere much more quickly. This is not a fair comparison, for there are so few, but a passenger aboard a rocket is responsible for 100 times more climate-changing pollution than a passenger aboa
