And now for some good news.....

By Kevin Dufour, Chapter Member; LEED AP O+M




As an environmental scientist and sustainability consultant, I try to stay current with the latest research about our environment and in particular, climate change.  Often times the flow of information is relentless and sometimes downright depressing.  Constantly hearing such stories as how the California drought and Australian Heatwave have been definitively linked to to climate change, or, that birds ranges have been pushed further toward the poles and that many species may face future extinction can eventually get you down,  Why even the mangroves, that iconic symbol of the tropics, have been relentlessly marching away from the equator due to warmer winters.  It can be hard not to devolve into pessimism.  

A Reason for Hope.

However, I recently had an enjoyable and encouraging conversation about climate change. The information was correct, current, and even nuanced. My partner in conversation knew about ocean acidification, the natural drivers of climate change, attempts at mitigation and resiliency, feedback loops, and the basic principles of atmospheric science. He was ten years old. If he is that knowledgeable, then perhaps, others in his generation are so informed. This is a cause for optimism indeed. I thought that I should share some positive stories and that such would help those of us in the vanguard of the green movement carry forward. Perhaps such items would help keep the wolves of despair at bay for a while longer.

Positive Efforts

There have been several news stories that have focused on the potentially positive efforts.  These include stories of technological innovation and political will.  I was particularly encouraged by the development of floating solar panels. What a great idea.  This helps solve the issue of devoting so much productive land to solar power generation.  These panels can be deployed on reservoirs, industrial/agricultural lagoons, even at sea.  Obviously care must be taken to not disrupt the ecosystems with the shade these will create but it can turn non-productive water areas into electrical generators.

Greener Ag.

A second area of innovation that i believe may hold much promise is in the area of agriculture.  Agriculture is often vilified due to its impact on erosion, chemical run off, and the detrimental effects of mono culture cropping.  Major advances have been made that go a long way to minimizing those impacts.  A consortium of companies and governments has launched the climate smart agriculture initiative.  This seeks to use technological and agronomic best practices to both work with a changing climate, and to mitigate it impact, as much as possible.  This will be vital to continue to produce food, in as sustainable manner as possible, to feed the world despite the increasing pressures climate change will present..  There are critics, and such a program would need to monitored, but, its about spreading best practices around the world, increasing yields, and reducing or eliminating environmental impacts.  All ideas must be on the table and this is a good start. 

The precision agriculture movement works hand in hand with Climate smart agriculture by leveraging technology to minimize impacts and maximize productivity.  At first glance this seems like science fiction but it is real and it is being used today.  Precision agriculture involves the use of advanced sensors to detect drought stress and pest pressure on crops.  It uses guided applications of nutrients, pesticides, and water to alleviate those issues.  Rather than using a crop duster to bombard a field or broadcasting fertilizer where it may not be needed, the applications are targeted to the individual plant in need.  Water is only applied exactly where needed and in a manner to minimize evaporation.  The end result is greater productivity, less costs, and far less impacts than current practices.  As I mentioned, this is being done now.  The higher yields and lower use of nutrients and chemicals reduces cost to such an extent that the return on investment can be as little as 2 to 3 years. No matter how you slice it, that is good news.

China, Business, and Citizens stepping up.

Another area of positive movement is world wide acceptance  of the challenges we face. That is no more evident than in the burgeoning environmental awakening taking place in China.   Make no mistake about it, China is a mess and will continue to be a mess for a long time.  That said, they are making  dramatic strides in a developing environmental protection system.  They have begun instituting trial cap and trade systems. They have banned all coal burning in Beijing by 2020 and placed limits on coal burning power plants.  Most transformational of all has been their establishment of  a system that allows for public interest lawsuits as a means of driving environmental change.  Even if they are harvesting "low hanging fruit", China is making substantial gains and putting the US to shame.

While I have been disappointed by the United States congressional lack of leadership on climate change, I have been heartened by the actions of its citizens. A huge crowd gathered in NYC to march for climate action. Ironically just a couple of days earlier Gov. Christie - who pulled New Jersey from the Regional Green House Gas Initiative - was in NYC to speak before a donor convention for the climate change denying Koch brother backed Americans for Prosperity super PAC. I guess its two steps forward, one step back.   Students have taken the lead in advocating for college endowments to divest themselves of carbon intensive investments.  This strategy is not just ethical investing from the days of combating apartheid but it also makes simple economic sense.  If, in order to meet the 2 degrees C climate benchmark, we must leave large amounts of oil, gas, and coal in the ground - do proven reserves have any value?  Even the Rockefellers, of Standard Oil fame and fortune, have announced plans to divest up to 50 Billion from fossil fuels including tar sands. 

The Rockefeller Fund is not the only corporate citizen pushing for action on climate change.  Many corporate citizens have stepped to the plate.  You can argue whether or not it is ethics or profits that drive this new found idealism but I care not, the end result is the same.  Both Google and Microsoft and even News Corp.  have announced plans to withdraw all funding and support from the climate change denial bill mill of the American Legislative Exchange Council.  A sure sign that corporate citizens are viewing climate change as a risk to their bottom line is the alliance between Henry Paulson, Michael Bloomberg, and Tom Steyer.  This project, funded by heavy hitters from all sides of the political spectrum illustrates how climate change can, if thoughtfully addressed, cross all political boundaries.  The Risky Business project "focuses on quantifying and publicizing the economic risks from the impacts of climate change." In my mind, it's the action that matters more than the motivation.  I don't care if climate change is addressed to preserve corporate profit and minimize risk or if it is being done to save the world, so long as action is taken.

Positive Results.

We are starting to see some positive outcomes from actions that have already been taken.  This past year, 2014, is the first year that we have not recorded a single exceedence of the Ozone standard (Smog) in Massachusetts.
In fact, air quality all over Massachusetts and the united states has been getting steadily better and better.  This is a clear testament to the impact that forward thinking governmental policies can achieve when driven by an educated and motivated populace.  The image below and the fantastic animation at this link shows the reduction in air pollution over the last several years as imaged from a NASA satellite.
Finally, the antarctic ozone hole, remember that, has been healing itself.  Ever since the Montreal Protocol banned chlorofluorocarbons and other stratospheric ozone depleting chemicals, the earths atmosphere has been steadily healing.  This again is illustrative of the fact that concerted collective action can effect great change.

  Even the Economist has pointed out that the greatest advances in climate change have come from large governmental action including treaties, energy standards, efficiency, and even building codes. Progress is happening and its happening in unlikely places and with unlikely partnerships.  Hey, even the Economist is covering climate change, that's a reason to be hopeful.

Cape Cod Hurricane Category 3 Flood Model

By John Gravelin, Linnean Solution

This image of Cape Cod represents a Category 3 Hurricane flood model under ‘perfect’ storm conditions during an average (mean) tide. The flood layer was obtained from the National Oceanic and Atmospheric Administration (NOAA) Hurricane Research Division Atlantic Oceanographic & Meteorological Laboratory. The hurricane model is referred to as Sea, Lake and Overland Surges from Hurricanes (SLOSH).

The SLOSH models account for several variables of hurricanes, including the intensity of a storm, forward speed, storm trajectory, and initial tide levels based on observations from previous events. NOAA runs several hundred hurricane models over an area like New England and develops a ‘Maximum Envelope of Water’ or a baseline of flooding per hurricane category. NOAA also provides a flood model that represents “the worst case scenario for a given category of storm under ‘perfect’ storm conditions,” and takes the maximum of the variables above.

This image of Cape Cod represents the maximum flood damage possible under ‘perfect’ storm conditions. Areas in dark blue are most susceptible to flooding (particularly along the southeastern and northern shoreline of the Cape) and areas of light blue are least susceptible (seen around the southwestern part of the Cape towards Rhode Island). Even the least susceptible areas are vulnerable to flooding under certain storm conditions, and proper planning should consider ways to mitigate damage.

Institutionalizing Ignorance

Ignorance: state of being ignorant, lack of knowledge , education, or awareness.
I felt that I needed to get that definition in place right our front, before I start throwing bombs. My first few posts have been on items that have been rather mundane such as, groundskeeping and maintenance plans.  However, over the last couple of weeks several things have come to my attention that both angered me and made my wonder about the long term viability of the sustainability movement.


The children are the future

The first thing that got may attention was a concerted effort to pollute the minds of school children by requiring, under force of law, the teaching of climate denial in schools. Oklahoma, Colorado, and Arizona are all debating bills that refer to global warming as a "theory" that is "controversial" and riddled with scientific weaknesses. This, despite the fact the National Academy of Sciences, as well as major national academies of science around the world and every other authoritative body of scientists active in climate research have stated that the science is unequivocal: the world is warming and its primary cause is human activity.  The veracity of climate change is unshaken despite the fact that this spring has been ice bound and last winter was virtually snow less. These variations are explainable.  The trend line of the data has been verified, despite the claims of climate change deniers.

These bills are being advanced under the canard that students need a "balanced" perspective " to develop critical thinking skills they need in order to become intelligent, productive and scientifically informed citizens." (These efforts have been crafted and honed over decades, if you want to learn more, an excellent PBS documentary is here.) This is the latest approach to arguing for an idea you can't possibly support with evidence - the false equivalency.  The powerful interests behind climate denial are well aware that the vast weight of evidence is against them so they propose that , for the sake of balance and fairness, both sides need to be considered equally.  This is bunk.  This is the same argument that was made between creationism and evolution.  One side has the vast weight of the generations greatest subject matter experts all reaching some form of accord, the other has....nothing. The best support that they muster is a selective interpretation of the data.  Sure they can point to a scientist or two - often not even a climate scientist - to support their position.  The tobacco industry would occasionally find a scientist who did not believe that smoking damaged your health, it did not mean that those scientists opinions should receive the same weight as the avalanche of opposing colleagues. 

While these laws seem laughable on their face, this is not something to be trivialized. While the above referenced law is up for debate in 3 states, it has been raised in 10.  The forces that propose these laws are very very well organized and heavily subsidized.  They are also expert at influencing the political process to gain a built in, legislatively mandated, advantage.  Kudo's for them.  If you care about something, you need to fight for it.  I fear that the pro-sustainability constituents may not be up for the fight.  Examples of their efforts include efforts to prevent the disclosure of fracking fluids, efforts to blockade renewable energy, and even developing a "Global Warming Curriculum for K-12 Classrooms." 

Now, we get to the part that worries me.
