Do and/or Die

Peter Wadhams has ample reason to believe that when a truck ran him off the road, it wasn't just an accident. The Cambridge professor is a recognized and outspoken Arctic sea ice expert who is calling for a dramatic curtailment in fossil fuel use, lest the arctic meltdown shift into a cataclysmic series of positive feedback loops. At one point, the professor speculated that oil industry or government agencies had hired the driver to kill him, just as three other sea ice scientists encountered suspicious demises in the past few years. Causes of their untimely deaths were ascribed to falling down stairs, lightning, and vehicular collision while biking.

Death threats and assassination are nothing new to climate and environmental activists. The least you can do when so threatened is to put it on record, prompting an investigation if you are killed. Professor Michael E. Mann, famous for the hockey-stick graph of global temperatures, recently leveraged his potential martyrdom in a push back against the rhetorical garbage that continually belches from Trump's craw. 

In August 2016, Dr. Wadhams sealed his testimony about our predicament in the form of a book titled, A Farewell to Ice, fortuitously published a few months before the canary in the Arctic began to swoon with temperatures now 50 degrees Fahrenheit above normal, high enough to melt ice in Winter. Wadhams sees 2017 as the first likely summer without a polar ice cap, which would remove the reflecting shield from the Arctic, causing more warming, which would allow undersea permafrost beds to disgorge greater amounts of methane stored there. He has identified ten positive feedback loops associated with Arctic warming.


Hope, nonetheless, springs eternal and Wadhams puts his hope in a radical shift away from fossil fuels and a Manhattan project scale effort to draw down atmospheric carbon. If we don't carry out this change before 2035, Wadhams fears it will be too late. Leaving out the geoengineering piece, the Green New Deal offered by the Green Party could bring the U.S. to 100% fossil-free energy by 2030. If Wadhams is right, there is little room for letting this timeline slip. Either we change our way of living, or our world will change intolerably. Or, maybe we will die from unnatural causes before that, because we were bold enough to point out the problem.

Playing with Fire

I am proud to be a Marylander just for the simple fact that our state is a leader in the fight against climate change.  Maryland's Greenhouse Gas Reduction Act (GGRA) rivals the plans of such progressive states as Switzerland in the rapidity envisioned for reducing emissions to fight global warming.  Since GGRA was enacted in 2009, Maryland has actually reduced greenhouse gas (GHG) emissions faster than required by the plan, which calls for a 25% reduction of the 2006 level of emissions by 2020.  We are now at the point where an update to the plan is needed, as the Act must be reapproved in 2016.

Insofar as the real importance of Maryland's plan is not in drawing down emissions, but in showing other states how it is possible to do so while growing the economy, the GGRA is laudable. I do, however, have my reservations as to motives and the ultimate outcome.  It's not that Maryland is just so small as to have little bearing on global warming, it's that, at this point in the game (and more so in 2020, when other states might begin catching on), we cannot reduce atmospheric CO2 enough, fast enough to avoid catastrophe unless we immediately abandon business as usual (and/or put all our hopes in a "hail Mary" geo-engineering program).  By "business as usual," I include the reliance on economic growth for sustainment of the economy.  A major result of capitalistic, exponential growth is that it drives us deeper into fossil fuel dependence, while these limited resources become ever more expensive and environmentally harmful to extract.

Case in point: the Cove Point LNG export facility.  One of the most frequent concerns raised in public hearings held by the Maryland Climate Change Commission was the amount of GHG that would be induced by the facility's operations. Calculations show that this total would negate more than half of the GHG reduction progress made throughout the state since 2006 when the final results of the GGRA are tallied after 2020.  This effect was not included in the GGRA Plan Update, in spite of public input.  Even if it had, much of the effect would be masked by the fact that a good portion of those emissions are "off-shored," either to other states where the gas is shipped from, or to the end users overseas.

To be fair, it seems that Maryland is not in the least in control of whether the Cove Point expansion takes place. The climate commission considered it to be too much of a hot potato to even address it, and even climate-friendly Governor O'Malley wouldn't challenge it during his term.  This gives me little hope that the District Court of Appeals in Columbia, MD will rule favorably toward the environmental petitioners in their suit to require the FERC to re-evaluate their decision to allow the Cove Point expansion.

It's not that the powers that be really care whether Maryland's economy grows under business-as-usual, it's that they want to continue the bubble economy at the national level as long as possible, at least until it becomes apparent that we have no hope to avoid human extinction other than a "hail Mary" play.
