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
The Breakthrough Institute has been busy. Their director of climate and energy has published a critique of the use of RCP8.5 as BAU.* While it is true that many papers misinterpret RCP8.5 as being the worst case scenario and that this is equivalent to BAU, the authors of the RCPs recently reminded the climate community that RCP8.5 assumed maximum burning of coal , which is not what is … Continue reading Misrepresentation of business-as-usual emissions: The red herring of RCP8.5

Personally, I would rate the likelihood of staying under two degrees of warming as under 10 percent. – Michael Oppenheimer 2017
Do not depend on the hope of results. You may have to face the fact that your work will be apparently worthless and even achieve no result at all, if not perhaps results opposite to what you expect. As you get used to this idea, you start more and more to concentrate not on the results, but on the value, the rightness, the truth of the work itself. – Thomas Merton
Under a concrete sky on 5 November 2014, Michele and I awoke to realize that Paul LePage had been re-elected as governor of Maine. Once again, Mainers had split their votes three ways and LePage was elected by a minority of the voters to another four-year term. We were deeply disappointed because during his first term LePage had made clear his disdain for environmental concerns. Little did we know that the next few years would make LePage’s first term look like the good old days. Continue reading “The Long Game: Facing Reality in the Environmental Century”

“I don’t think of all the misery, but of all the beauty that remains.”
On Sunday, 30 April 2017, the New York Times reported that global marine fisheries are being pushed to the brink. This and countless other imminent losses prompt me to once again point out that management of the global biosphere is necessary if we are to have any hope of controlling climate change and feeding ourselves. Human impacts on ecosystems are pushing the living planet into a new regime characterized by disrupted ecological relationships and accelerating extinctions on local, regional, and global scales. Ecological disruption causes ongoing positive feedbacks from widely-distributed natural sources of emissions, thus further disrupting the climate system. Globally, we are approaching a state of unmanageability on many fronts. Continue reading “Ecology, Loss, and Triage”
Assembling on the National Mall before the March for Science 22 April 2017.
‘Science is my passion, politics, my duty’
– Thomas Jefferson
On Saturday I joined more than 20,000 scientists and supporters of science to March for Science in a soaking rain on the National Mall in D.C. The experience was exhilarating and inspiring. It was a much needed antidote to constant stream of bad news for our environment emanating from the White House and Congress. These days, I sometimes feel as though we are entering a dark time when reason and learning will be driven from the mainstream of public discourse. The March for Science showed that we have strength in numbers and that scientists can, at least for this golden moment, stand united. Continue reading “On the Fear of a Backlash Against Science”

A planet that can’t sustain its greatest reef will eventually become a place that won’t support human life. – Tim Winton, 2017. The Australian Marine Conservation Society.
For the first time the Great Barrier Reef has experienced two back-to-back bleaching events, which have been driven entirely by extreme sea surface temperatures. The devastation is hard to miss, unless you are not looking. Successive generations often experience the conservation phenomenon known as shifting baselines of perception. A boy’s granddad may remember when they fished for more than 15 species of fish in the Gulf of California, but the boy believes that the five remaining species are normal, i.e., a new baseline. As the disruption of the biosphere accelerates and reductions in biodiversity ensue, it will become increasingly hard for each generation to perceive current conditions as normal, assuming that they are paying attention.

One of the strongest hurricanes on record, Ivan, was photographed on September 11, 2004 from an altitude of about 230 miles by NASA Astronaut Edward M. (Mike) Fincke. At the time, Ivan was in the western Caribbean Sea and reported to have winds of 160 mph.

There are many uncertainties about how the new administration will govern beginning on 20 January 2017, but it is all too clear that addressing climate change will not be on the agenda. Continue reading “Diminishing Options and The Climate Endgame”
