Paris Climate Talks: What does it mean for the Bay

Image result for cop 21For the past two weeks, negotiators from across the globe have convened in Paris for the 21st United Nations conference on climate change. One hundred eighty six countries have come with ambitious pledges to limit greenhouse gas emissions. While past conferences have attempted to negotiate a treaty that would keep warming to 2 degrees Celsius, over 100 countries have now pushed to try and keep warming to 1.5 degrees.



It is unclear if this goal is possible given the amount of carbon we have already added to the atmosphere and the voluntary pledges being offered so far. Our current path including these pledges sets us up for 5 degrees, and we have already passed the 1 degree mark. Meeting a goal of only half a degree more of warming would require an unprecedented shift to a decarbonized economy across the world and would also require removing large amounts of carbon dioxide from the atmosphere. Because of the urgency, the final treaty will likely have specific requirements to “ratchet up” the promises from each country. The goal is that by the year 2030, all countries would be on a common pace to revise these promises every five years.

Much of the focus at the conference has been on lowering the demand for fossil fuel and using technology to limit emissions while switching to renewable energy. This directly ignores the scientific consensus that 80% of known fossil fuel reserves must say in the ground for us to remain below 2 degrees of warming. Keeping it in the ground is not being discussed at this point, and here at home, the United States promotes and subsidizes fossil fuel development while trying to limit carbon emissions – a very difficult task.

In Paris, and here at home, you will hear two major topics of discussion when it comes to climate change: mitigation and adaptation. Mitigation includes activities that will reduce or prevent greenhouse gas emissions, such as switching to renewable energy or preventing deforestation. Adaptation includes activities that reduce harm from the effects of climate change, such as removing infrastructure from flood prone areas, planting trees and treating stormwater.

Much of Save The Bay’s work in habitat restoration falls under adaptation. We are restoring salt marshes so that they provide habitat value for as long as they can be sustained. We are supporting dam removal as a way to connect rivers so that fish can migrate. We are helping cities and towns to move flooded infrastructure and treat stormwater. We also support mitigation by using solar panels at the Bay Center and advocating for renewable energy. On Tuesday, the RI Governor signed an executive order that will direct state agencies to get 100% of their energy use from renewable sources by 2025. It also supports zero emission vehicles, public transit and green buildings. 

There is a third piece of the puzzle, however, and that deals with loss and damage.

The problem, of course, is that no matter what we do in the coming years, some amount of sea level rise and temperature rise are already “baked in” and this will bring significant loss and damage to everyone on the planet to varying degrees. Already, Pacific Island nations are faced with abandoning areas that are uninhabitable, and droughts and floods are forcing people off their land.

This loss and damage is a bone of contention at the talks because poor countries feel that wealthy developed nations should shoulder the burden for making payments to them as restitution for causing much of the problem. Beyond money, assistance would include providing these countries with the capacity to cope and welcoming refugees from climate change disaster zones.

The sad reality is that so much damage has already been done we are beyond talking about mitigation and adaptation and are realizing that we could soon be dealing with a vast humanitarian crisis. The scale of that crisis depends on the strength of this and future climate agreements and how quickly they are acted upon by all the countries of the world.

Celebrating one year of gas free driving during Drive Electric Week


Image result for drive electric week


Last summer, I interviewed Save The Bay’s Facilities Manager about his decision to lease a Chevy Volt. The Volt is an electric drive vehicle with a gasoline engine for extended range. The all electric range is about 40 miles, after which a gasoline engine takes over. This is slightly different from a hybrid engine which switches back and forth from gasoline power to electric power during driving. After doing some research of my own, I decided last September to lease an all-electric Nissan Leaf, and go gasoline free. I like the simplicity of having one engine and virtually no maintenance other than tires and brakes.

Driving an all-electric car does take some planning ahead, and is best for city driving. The range varies widely depending on outside temperature and driving conditions. On good days, the range can top 90 miles with moderate driving speeds, but winter weather and use of the heat lowers the range under 80 miles. The car starts to warn you when running with under 20% of the battery remaining, so I generally take 20 miles off my effective range when planning my driving. With a battery instead of a gas tank, I feel like there is a direct feedback and connection to my own energy consumption and driving habits.

Rhode Island Supports Electric Vehicles
In 2013, Rhode Island partnered with National Grid to install 50 public charging stations through the ChargePoint Network. These stations are free to network members for the first four years while owners pay for the electricity. After four years, owners of the stations can decide to keep them free or begin using a fee based system. The stations are distributed throughout the state and are located at the state beaches, malls and restaurants such as Cilantro Grill and Chili’s, and at other locations such as Rhode Island College and Bryant University.

But what About the Electricity?
If you are interested in a direct comparison of energy consumption and costs for an electric car and a gasoline car, here are some of the things I have learned. One gallon of gasoline has the equivalent amount of energy as 34 kilowatt hours (kWh) of electricity. Our second car, the Honda Fit, gets about 34 miles/gallon or about 1 mile per kWh. My Leaf diagnostics tell me that I average about 4.6 miles per kWh, or the equivalent of about 156 miles per gallon. The 2015 Nissan Leaf advertises an average miles per gallon equivalent of 114 miles, so either I am very efficient or my car is not very accurate.


The 2015 Nissan Leaf battery holds 24 kWh of energy. This means that a full charge at 16 cents per kWh costs about $3.84. I have been using about 200 kWh at home every month, for a cost of about $32. It also means that at an average of 4.6 miles per kWh, I should have a range of 110 miles, which is kind of pushing it. I have heard that the diagnostics are not very accurate, and that is something being worked on. 

To me, all those numbers mean that my electric car is almost five times more efficient than my gasoline car, regardless of the fuel type. Because of regenerative braking technology, the brake pads last up to three years longer. Fewer fluids and oils means less contribution to stormwater pollution. No exhaust means I am not contributing to low level ozone pollution, the major cause of air quality alert days in the heat of the summer. In addition, electric vehicles emit only 19.8% of the total heat emitted by conventional vehicles per mile, reducing the heat island effect in cities.

What About other Sources of Pollution?
Electric vehicles do create more pollution during the manufacturing process, and they do require electricity to be generated somewhere, using some type of energy source. The best scenario would be to plug in to a solar panel array or to purchase green energy through your electric company. Not all parts of the country are set up to distribute electricity from clean sources of fuel. The east and west coasts, however, happen to be areas where the electricity mix is steadily becoming more and more renewable.

According to the Sierra Club, in Massachusetts EVs have about 70% lower greenhouse gas emissions than conventional cars. If you are interested in seeing the energy mix going into New England’s electricity generation in real-time, check out this site from ISO New England (our energy grid operator).

The Future of Electric Vehicles
In October 2013, eight states which include Vermont, Massachusetts, Rhode Island, Connecticut, New York, Maryland, Washington and California, signed a pledge to get 3.3 million EVs on the road by 2025. I am fairly confident that we will soon reach a tipping point and this goal will be easily surpassed. When the 2018 models start rolling out, we will see range go up over the 200 mile mark and electric cars will be mainstream. Electric options are available from most major car companies already.

The problem with being an early adopter, however, is that depreciation is relatively high, given that the technology is getting so much better with each new car model. This does provide some opportunities, however, if you are looking to get into the electric car game and save a bunch of money. I am very happy with my choice and am looking forward to seeing what happens. I am already fighting for space at the public charging stations that I use, so I know there is a growing crowd out there with me.

Omega Pond Fish Ladder opens up the Ten Mile River

After several delays and technical challenges, the Omega Pond fish ladder at the mouth of the Ten Mile River was finally opened just in time for this year's spring fish run. Herring were waiting at the dam when the ladder was opened, and fish were seen making their way to Hunt's Mill where an annual fish count is done by volunteers.

Save The Bay's connection to this project began in 1996, when  Paul Bettencourt took Wenley Ferguson on a tour of the ponds where he once fished for herring, now long since filled in. They stopped at the Omega Pond dam, where Paul shared his vision of restoring the fish run. Dick Quinn, an engineer with the US Fish and Wildlife Service, completed a conceptual design for three fish ladders, and the project began in 2001 with an Army Corps of Engineers feasibility study. The project was a collaboration between many state, federal and local partners including Save The Bay, the CRMC, DEM, the City of East Providence and the Ten Mile River Watershed Council.


About 65% percent of the funding for the project was provided by federal agencies including the U.S. Environmental Protection Agency (EPA), the National Oceanic and Atmospheric Administration (NOAA), and the U.S. Department of Agriculture’s (USDA) Natural Resources Conservation Service (NRCS). This funding includes about $5 million from the Army Corps of Engineers. 

Now that three fish ladders are in place, herring have three river miles and about 340 acres of habitat in which to spawn. They can now make their way to the Massachusetts state line, where they find the next dam at the Pawtucket Country Club. This dam is part of the Ten Mile River Reservation and is owned by RI DEM. The Massachusetts Division of Marine Fisheries has been supporting this project and provided fish from the Nemasket River herring run in Middleboro. These fish were stocked into the upper Ten Mile River to help maintain the run. The run was also maintained by a group of fishermen who for over ten years scooped returning herring and stocked them into the river under cover of darkness. These scooping events became celebrations as more and more fish returned and several thousand fish were helped over Omega Pond dam. 


Save The Bay will continue to work on this project and will advocate for continued river restoration. Water quality improvements are still desperately needed and the upper Turner Reservoir and Central Ponds often experience blooms of toxic blue-green algae. The flow in the Ten Mile River, like many of the Bay's small tributaries, is dominated by wastewater effluent. The Attleboro treatment plant is under strict new permit limits, but nutrient pollution in stormwater and from birds and wildlife is still contaminating the river. Opening up the fish passage is only part of the story. True habitat restoration will take work on many fronts including water quality and in stream habitat. We can now begin a dialogue with Massachusetts about additional restoration opportunities over the border, and the work is just beginning!

Responding to Our Changing Shorelines

This week, the habitat restoration team has been at work on projects that will help create resilient shorelines along the Bay. In Warwick, we have been removing pavement at the ends of roads where they dead-end on the shoreline. Many of these roads were damaged during recent storms, or are under water at very high tides. The pavement was located in areas that would otherwise be wetland, and they provide important public access points to the shoreline. We have been able to preserve the public access paths while creating an area for stormwater to infiltrate and for plants to grow. See this article in the Warwick Beacon.

These projects are part of a larger effort for Save The Bay and the Coastal Resources Management Council to adapt to rising sea levels and coastal flooding. As our shorelines retreat, removing infrastructure from harm's way is an important way to save money and protect the public. We are also helping salt marsh to remain and transition to new areas.

Another project has been taking place at King's Park in Newport. This pubic beach has also been eroding as sea level rises, and the park often floods during high tides and storms. Natural erosion control is being created with sand filled coconut fiber envelopes that protect the shoreline. This low-lying area of Newport, near Wellington Avenue often floods when water backs up through the storm drains and into the neighborhoods. This article in Newport This Week helps to explain the project.

Driving Electric

A major shift in personal transportation is coming with the wide availability of electric cars and the promise of the development of autonomous vehicles. Are electric cars only for “early adopters”, or should we all be rushing out to the dealer for test drive? Have you considered buying or leasing an electric car? I am still driving a more than 10-year-old Subaru and am dreaming of something a little more eco-friendly. I would love to go electric, but like many people, I have a number of questions about whether this would be a viable choice for me. I decided to ask Save The Bay’s Facilities Manager, Mike Russo, about his decision to lease a Chevy Volt.

Q: So Mike, why did you choose the Chevy Volt?
A: The Volt is American/Detroit made, and after the recent market collapse, it seemed like a good time to help GM advance the ball. GM has thought out the technology and the Volt was definitely ready for prime time.  (Note: the Volt is powered by an electric motor that is always operating on electrical energy.  Once the battery has exhausted, the power to move the vehicle forward comes from a gasoline engine that generates the electricity to power the motor. This feature had enormous appeal from a practical/engineering perspective). Also, it felt like a good time to be as petroleum-independent as possible, and the Volt's battery "range" of + 40 miles fit my commute so well gas stations are something that are now easy to avoid. 

Q. Did the fact that the Volt has a range extending engine help with this decision? Do you think you could get what you need from a car that was only electric with no back-up?
A. Without many convenient charging stations in RI, at this point in time a range-extending motor/engine combo is critical.  Ultimately, the range of the Volt's lithium batteries and the overall technology will exceed what we are looking at today. Driving a vehicle that seamlessly gets 40 MPG after it goes beyond its electric range makes a lot of sense, and I am willing to be a bit of a guinea pig.

Q. Did you notice a change in your electric range in the very cold weather?
A. During the winter months, the Volt's display, when fully charged, says the vehicle's range is 38 to 40 miles.  That is down considerably from the summer range of + 48 miles. One thing that doesn’t normally come up in conversion is the fact that, in winter conditions, you see the "engine running due to temperature" message come up on the display.  That is on for 20 to 30 seconds every few miles and I presume the Volt's engine is running to keep the vehicle's lithium batteries "happy."  
 
Q. Is the low cost of operating the car (electricity/vs. gas) a good incentive? Have you ever used a public charging station?
 A. I am new to this type of driving and am still getting used to it.  My normal gas mileage is between 115 MPG (winter) and more than 150 (summer).  Overnight, a normal "full" charge costs approximately $1.00.  That is the cost of recharging the battery that was drawn down about 30 "miles" using only the Volt's electric motor. There are many ChargePoint stations out there, but not that many in RI and I have yet to make use of one. 

Q. What are your favorite things about driving an electric car, and would you recommend it to our members, supporters, and readers of the blog?
A. Hands down, the best part is being able to ignore gas stations. The Volt took some getting used to, but I am all in now. Obviously, there is no "free lunch" here. If we want to move ourselves around, trade-offs are required. The concept of all those individual internal combustion engines, spewing who knows what into the environment, does freak me out a bit.  Not being a part of that is my preference. 

Recommendation-wise, the more the merrier!  If an electric vehicle fits someone's driving "style," they need to find one they can live with for three years. Consider leasing this kind of progressive technology and give it a go. Right now I am generating my own set of numbers and will let them tell me what I can/want to do when this transportation "experiment" is over.  But if you ask me now, my initial impression of this technology is positive as heck and I am looking forward what the future holds!     


Thanks, Mike for sharing your thoughts! I may just take a harder look at this new technology.

One Fish, Two Fish...

Spring has arrived, even if it doesn't feel like it. Increased stream flow and warmer water are triggers for migrating fish that it is time to mate. When they feel the urge, they come back to their home rivers to lay and fertilize their eggs. Right on cue, a river herring was seen on Buckeye Brook in Warwick near the first day of spring. The numbers of river herring returning to Narragansett Bay are extremely low when compared with recent history, as I discussed in my last blog post. While we try to reverse the trend, volunteer fish counts are an important way to keep an accurate estimate of the population size of local fish runs.

Groups of volunteers will be out again this spring to count herring at several locations around Rhode Island. Volunteers spend 10 minutes at a site counting the number of fish that pass upstream. The three largest runs that are monitored by RI DEM are Gilbert Stuart Mill in North Kingstown, Nonquit Pond in Tiverton, and Buckeye Brook in Warwick. At Gilbert Stuart and Nonquit, electronic counters at fish ladders assist DEM in addition to visual counts. Buckeye Brook is one of the few places in the Narragansett Bay watershed where migrating fish are unimpeded by a dam and can swim freely to their spawning area in Warwick Pond. At Buckeye Brook, fish are counted by volunteers at a culvert utilizing a white board that is placed on the stream bed to help see the swimming fish. Last year's count revealed that an estimated 45,244 fish returned to the river, while in 2012, the count was closer to 90,000.

The last several years have brought newly opened fish runs in to focus as well. New fish ladders and a dam removal on the Woonasquatucket River have opened up an historic fish run that will hopefully grow through the years. Counts will begin April 1st at both Rising Sun Mill and Riverside Park in Providence. The Ten Mile River Watershed Alliance will be conducting fish counts at Hunts Mill on the Ten Mile River.

A newly completed fishway project at Kenyon Mill will allow fish access to the entire reach of the Pawcatuck River up to Worden's Pond, and the removal of the Pawtuxet Falls Dam in 2010 has opened up the first seven miles of the Pawcatuck River in Warwick and Cranston. While the volunteers are out mostly counting river herring, several other species migrate to our rivers in the spring including American shad, sea lamprey, white perch, and American eel, which arrive in their juvenile stage to live their adult lives in fresh water.

A video monitoring system will be in use again this year on the Mill River in Taunton to help the Massachusetts Division of Marine Fisheries study recovery of that system. Many species of fish were seen last year including those that migrate within the river, like yellow perch and brook trout. With so many restoration success stories, this is a perfect time to learn more about the sometimes mysterious life cycles of these important fish species.

Remembering Not to Forget

How did we lose sight of the riches our streams and rivers once provided?  Accounts from early European settlers tell of unimaginable numbers of fish filling the rivers during spring spawning runs. There were so many fish that thousands could be caught in a day, and hundreds were placed in fields as fertilizer. Eels were in such large abundance that they were used for everything from horsewhips to hair oil. It’s been estimated that eels once made up one-fourth of all fish biomass in rivers on the Atlantic coast.

In his book, RunningSilver, John Waldman talks of the shifting baselines syndrome where we begin a pattern of forgetting that over the generations shifts our understanding of the true nature of these systems. You can say the same about global warming. As each generation becomes more and more used to a world without snow, we will forget that outdoor ice skating was oncecommonplace in Rhode Island and will believe that ice on Narragansett Bay is an“extraordinary” occurrence.

In the beginning, fish runs were preserved with bypass channels as mills were built, and farmers would come and take dams down by force if necessary. A 1735 Massachusetts law did not allow dams on rivers that would serve as a barrier to fish. This law was generally ignored and as rivers were taken over by human machinery, many mill owners just waited until the fish runs became smaller and smaller to the point where people forgot. They then claimed that fish had never run in the river, and it made no economic sense to restore them. A 1920 state inventory of river herring found that the Mill River in Taunton was so badly polluted by manufacturing waste that restoration of the fishery would be “impossible”.

We began to forget, but the fish did not. The fish persisted and even in the beginning of this century runs of river herring on the Taunton River remained above two million fish. Today, we have removed some obstacles and have restored water quality to a degree, but the fish are not returning. We all speculate on the reasons, and they are many.

Slowly, our public resources were taken over by private interests and now restoration must be done with public money. Many private dam owners are willing to take down their unwanted dams, but not without the help of federal and state agencies who pay most if not all of the cost. Because fish passage restoration is a goal of the government, we are willing to see this happen. State agencies have the duty to protect the public, so they inspect private dams, rather than require owners to do it themselves. How did we get here, and why do we allow these attitudes to persist? It certainly is the tragedy of the commons, but we should not leave it at that. We should reevaluate what a shared resource means for all people and all species, and not forget what we once had, even if we can’t go back in time.
