Attached is a pdf of my lecture for Monday. I will outline the case for panic and action and provide the students with a sequence of lectures for the remainder of the semester. This is for BSC2862 Global Change Ecology and Sustainability at the University of Florida. Planetary Boundaries, Regime Shifts, and Sustainability

Ecological collapse in Florida is not hypothetical. It is happening now in south Florida where population pressure and the interests of agriculture have resulted in the annual recurrence of the biggest pollution catastrophe in the history of our state. It is happening now in our springs, streams, and lakes where nitrates have disrupted the normal ecological processes that kept these bodies of water crystalline. It is happening now as political and financial interests continue to delay and derail our ability to respond to ongoing climate and ecosystem disruptions.

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”
