Review of IPCC AR6 Synthesis Report

The Synthesis report released on 20 March provides a context for the three previously released parts of the AR6. This is a powerful indictment of the fossil fuel industry and our overall lack of progress in addressing this problem. The survival of civilization depends on our immediate collective action. After a single news cycle the mainstream media has simply moved on to other issues. I … Continue reading Review of IPCC AR6 Synthesis Report


Climate interventions are of two forms: those based on natural processes and those based on technology. Nature-based interventions involve the management of forests, agriculture, and wetlands. Technological solutions involve reducing global temperature through interception of solar radiation or direct removal of CO2 through chemical means or with biofuels and carbon capture. In this module we will review the risks and possible advantages of the most likely … Continue reading Geoengineering

Atlantic hurricanes has decreased in the first half of the 20th century but since about 1960 … Continue reading Review of IPCC AR6

Economic Models and the Real-World Social Costs of Carbon

Economic theory mandates that it is worth reducing CO2 emissions up to the point where the benefits are equal to the cost. The social cost of carbon is an estimate, in dollars, of the economic damages from emitting one additional ton of greenhouse gases into the atmosphere. This metric is inextricably tied to the Neoliberal Economics and used by the UN and most governments to … Continue reading Economic Models and the Real-World Social Costs of Carbon

No slack for UF and the methane power plant

Some have objected to my concerns about the new fossil-gas power plant at UF because they feel the administration’s options are financially limited due to the extreme expense of retrofitting the campus to remove dependence on methane to produce steam and chilled water. The new plant is budgeted at $200 million. Secondly, they point out the the new plant could easily be converted to hydrogen, … Continue reading No slack for UF and the methane power plant

Mission failure at the University of Florida

A version published in the Gainesville Sun 3 September 2021 The mission of higher education is the maintenance and renewal of civilization. This statement comes as an epiphany to many who hear it for the first time. Public higher education in the US has been diminished at the hands of legislatures and business interests who believe that higher education exists solely to serve the economy. … Continue reading Mission failure at the University of Florida
