New Report Warns Planet May Be Warming Twice as Fast as Expected By Bruce Melton First Published on Truthout, May 28, 2019 New earthshaking science will be coming out in the 2021 Intergovernmental Panel on Climate Change (IPCC) report that could nearly double future warming predictions. We have a window into this new science…
New Evaluation of Climate Models Reveals Abrupt Changes Ahead of Schedule It’s not the averages that will mess up your hair, it’s the gusts. This work on modeling the unmodelable (Drijfhout 2015) is a couple of years old now, but it gives enormous insight into why it is that “ice cube melt climate science” is…
Sing Delay, Delay, Delay When serious discussions about global warming gases and fossil fuels began in the 1980s, all that was needed to prevent what would become labeled as dangerous climate change was a reduction of the emissions of global warming gases. Since that time, we have emitted as much CO2 as we emitted in…
We have delayed too long and now must urgently reduce the load of warming gases already emitted to our sky. We have been warned this would happen for decades, we just didn’t think it would happen so soon. This is exceedingly bad news, though the good news with climate change is very good indeed. The…
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 warming in the short-term, but really only in a world…
The details of the temperature record are a lot more extreme than the National Weather Service averages reveal. Their current January average for Camp Mabry is 2.1 degrees above normal, but it’s nearly 5 degrees warmer than the 1980 average. Is this just the normal chaos of weather? The annual average Austin temperature has increased…
(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 risen by 34%, mostly in the last several decades. Global…
