“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”
This discussion took place on Thursday, 13 April, 2017. Here is a link to the video of the event.

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.

Scott Pruitt’s immoral denial of the reality of climate change is part of an assault on science that will promote the accelerating disruption of Earth’s living systems. The global consequences of this retreat from reality will be profound and irrevocable on any meaningful human timescale. The U.S. is the largest economy and the second largest emitter. Most the carbon pollution in the atmosphere came from us. Given the rate of climate and biosphere disruption, the administration’s aggressive embrace of fossil fuel interests poses an existential threat to civilization. The legislature and the executive branch are the handmaidens of an industry whose sole purpose is to mine and sell as much fossil carbon as possible. I see no effective means of turning this around in any timeframe that will matter with respect to our opportunity to salvage a livable planet. The window of opportunity for aggressive mitigation of climate change is almost closed. Continue reading “Denial and Consequences – Advice for Scholars and Scientists”

“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.

“Well planned sustainable biomass power plants are a viable source of clean renewable electricity, and this is helpful for the task of phasing out coal-fired power plants. Knee-jerk opposition to all biomass projects has no sound scientific basis and is harmful to attempts to stabilize climate for the sake of our children, grandchildren, and future generations.” — James Hansen, Climate Science Awareness and Solutions Program, Earth Institute, Columbia University Continue reading “Switching from whiskey to beer and the false promise of woody biomass”
