Dear Carl’s Climate Letters Readers:
After writing 2,168 letters beginning in late 2013, my dad, Carl Campbell, passed away on March 29th, 2022, in St. Louis, MO, at the age of 91 after a brief illness.
He began writing his climate letters when he was 81 years old and long retired from his career, an amazing feat that made his family and friends immensely proud. He considered his independent study of climate science and the posting of these letters to be the most fulfilling “job” of his life.
While studying daily weather maps and pondering issues such as anomalies in the polar regions, or the interconnection of precipitable water and greenhouse energy effects (from which he developed ‘Carl’s Theory’), my dad was constantly astonished at the rapidity of climate change.
One of his hopes was that someone, maybe a budding scientist, would carry on his research and explore new channels. But only time will tell.
On behalf of my dad, I want to thank you for your faithful readership regarding what he termed “the world’s number one concern.”
