It is 33 years now since the IPCC in its first report in 1990 concluded that it is “certain” that greenhouse gas emissions from human activities “will enhance the greenhouse effect, resulting on average in an additional warming of the Earth’s surface.”

A friend asked me if a discussion paper published on Statistics Norway’s website, ‘ To what extent are temperature levels changing due to greenhouse gas emissions? ’, was purposely timed for the next climate summit ( COP28 ). I don’t know the answer to his question. But this discussion paper is problematic for sure.

Manabe’s Climate Modeling. 2019 ) gives a good overview of Manabe’s particular philosophy of climate modeling which was very much focused on getting things to work, and not worrying too much about the details. These were very much the ideas that set the discussions in climate science in the 1990s.

Altering cloud properties influences Earth’s climate On sunny days, it’s clear that clouds leave shadows on the landscape. Climate scientists are interested in clouds for exactly this reason- clouds reflect sunlight, which has a cooling effect on surface temperatures. Cirrus clouds formed this way have many, small ice crystals.

We know we must now work to both cut greenhouse gas emissions to reduce the severity of climate change and at the same time work to adapt to the impacts we can no longer avoid. Gleick falsely accuses me of cherry-picking a quote from a 2019 New York Times story on Amazon fires. “If Why else use it?
