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

Review of IPCC AR6

This a comprehensive review of the AR6 for my students at the University of Florida. It may be viewed but not downloaded or copied. One error in the narrative is the statement that hurricanes are becoming more frequent. The overall global frequency of cyclones has decreased since the 1800s. 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

This is has been a terrific semester that has included some of the best students of my career. This is my year-end review of the lessons on climate change that have been presented in the three courses that I teach. I hope you find this useful. A correction: the CO2 concentration from NOAA just before the volcano shut down the Keeling laboratory at Mona Loa was … Continue reading Climate change year-end review 2022

The false summit of climate change progress

There are several reasons why the changes underway represent a false summit leaving an extremely steep climate landscape yet to be scaled. It is important to realize that most of these changes are promises, rather than anything close to becoming reality. In the US, we can count on GOP elected officials at the state and federal level to oppose most of the proposed changes to energy policy and climate change mitigation. The GOP will protect the fossil fuel industry in myriad ways that will leave the average voter at a loss to say exactly what is happening.

On the survival of civilization – Earth Day 2020

An Australian NGO has been following the anthropogenic decimation of our planet for the past few years. The group, known as The Commission For The Future of Humanity, notes that there are ten existential issues that could spell the demise of civilization during this century. No single one of these is unfolding in isolation because they are potentially mutually reinforcing calamities on a global scale. … Continue reading On the survival of civilization – Earth Day 2020
