Optimal Path for Avoiding Dangerous Change and Short-lived Greenhouse Gases

By | Abrupt changes, Methane, Uncategorized

Methane (and natural gas), and black carbon (soot) are short-lived greenhouse gases relative to carbon dioxide, N20 (nitrous oxide) and CFC (chlorofluorocarbons). Limiting these short-lived greenhouse gases have obvious benefits in reducing warming. Focusing emissions reductions on these gasses also gives the benefit of delaying…

Welcome to Climate Change Texas Part 1: What Can Be Done About Climate Change in Texas?

By | Abrupt changes, Agriculture, alternatives, Austin, Central Texas, Climate Catastrophes, Deniers and Delayers, Drought, forest health, Forest Mortality, Impacts, in-depth and Popular Press, rainfall, Solutions

As I have been saying in the first two installments of this series, climate change is already much more extreme than most scientists have been predicting. This is mainly because the majority of predictions are based on the “most likely” emissions scenario and because we…

Climate Change and Global Economic Dysfunction

By | Abrupt changes, alternatives, Arctic Sea Ice, Climate Policy, forest health, Forest Mortality, in-depth and Popular Press, Sea Level Rise, Solutions

Do you realize that ocean primary productivity has declined 40% since 1950? Or that, this year’s coral bleaching was worse than during the super El Nino of ’98? Or that, the Arctic was declared functionally ice free last summer for the first time in 14…

US Geological Survey Report – U.S. Climate Change Science Program. Thresholds of Climate Change in Ecosystems

By | Abrupt changes

(170 pages) Ecological thresholds occur when external factors, positive feedbacks, or nonlinear instabilities in a system cause changes to propagate in a domino-like fashion that is potentially irreversible.  Atmospheric carbon dioxide has reached levels unprecedented in possibly the last 24 million years. CO2 concentrations have…
