Ecology, Loss, and Triage

“I don’t think of all the misery, but of all the beauty that remains.”

–Anne Frank

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”

On the Fear of a Backlash Against Science

‘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”

Normalizing Disruption and Loss

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.

Diminishing Options and The Climate Endgame

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”

The Election and A Call to Service in The Anthropocene

“Elections have consequences.” – Barack Obama, 5 November 2008.

“Donald Trump can fool a lot of people, but you can’t fool Mother Nature.” Jacob Scherr, an attorney who is the former director of the international climate program at the Natural Resources Defense Council, 3 October 2016.


Climate change is complex. Within the scientific community, there is a broad consensus about its reality and cause, but experts hold a range of opinions about its impacts and how to address it. As any public scientist can tell you, it is hard to articulate a simple and compelling description of how the change of a few hundred parts per million of a trace gas can lead to potentially catastrophic consequences. Although complex in its interactions with natural systems, it is broadly correct to say that climate change presently amplifies the ongoing disruption of the biosphere driven by the forces of habitat destruction and extractive use of natural resources. By midcentury and beyond it will increasingly be a primary driver of the global transformation of ecosystems. The changes ensuing over this and coming centuries will be tectonic, but this message of scientific complexity and consequences does not play well in Peoria. Once again, the US political process has not made understanding this most critical of issues a prerequisite for the job of president.

What qualifies as scientific authority?

For The Natural Resources Council of Maine

“Listen, I’m not qualified to debate the science over climate change,” Speaker of the House, John Boehner (R-OH)

“…this 97% [of climate scientists accepting human-caused global warming], that doesn’t mean anything.” Senator James Inhofe (R-OK)

“Reality has a well-known liberal bias.” Stephen Colbert, satirist
