Several of you have asked for a summary of my views on global warming and climate change. You will find it in my new podcast.
I start by describing the history of the discussion about global warming, noting that the first paper to describe the effects of global warming was published in 1898!
I note that there were few concerns about a warming world until roughly 1970. In fact, some scientists worried about cooling and a potential ice age after a chilling period from roughly 1950-1970.
Temperature change from 1988-2022
But by 1980, concerns about a warming planet increased, with an estimate that the earth would warm by roughly 3°C (5F) by the time the concentration of CO2 doubled (about 2060-2070). Interestingly, a sign of the effects of increasing CO2 is a COOLING of the stratosphere, something that has been observed.
In this podcast, I suggest that global warming is a serious problem but not an existential threat to humanity. That there has been a lot of hype and exaggeration about global warming causing more extreme weather. Poor information that has harmed individuals and undermined real progress.
I suggest that the problems can be greatly lessened by adaptation and better forecasting, as we reduce our emissions of greenhouse gases and learn how to pull CO2 out of the atmosphere.
