Mr. President, I would like to thank my colleague from Oregon, Senator Merkley, who has done a tremendous job laying out the scientific case, the compelling economic case, the cultural case, and the global case for why we here in the Senate need to wake up, need to listen to the indisputable evidence of what climate change is doing in our home States, to our country, and around the world.
Mr. President, even now as we speak in this Chamber, my own three children--Maggie, Michael, and Jack--are asleep at home. And as I reflected on this past summer, I was struck by something--an experience we had--that was a simple and telling reminder of the steady changes wrought by climate change in our Nation.
Last summer we took a family vacation--a trip--to Glacier National Park. For those who have had the opportunity to hike in this majestic national park in Montana, it is the site of many striking and beautiful scenes, but there was one hike we took in particular that stayed with me. It was a hike to historic Grinnell Glacier--a glacier that is by many photographs over decades documented in its steady receding. In fact, since 1966 it has lost nearly half of its total acreage. We took a long and winding hike up the trail that takes you to Grinnell Glacier. You can't quite see until you come up over the last rise that most of what is left of Grinnell Glacier in the summers today is a chilly pool of water.
For my daughter Maggie and for my sons Mike and Jack, as I look ahead to the long-term future, I think we all have to ask ourselves this question: How many more changes are we willing to accept being wrought on creation, on this Nation, and on the world by the steady advance of climate change?
I know we can't simply take the examples of things such as Grinnell Glacier or what to me seemed a striking change in the cap of Mount Kilimanjaro. I first climbed it in 1984 and visited it again last year. There is a striking change, a visually powerful change. These aren't scientific.
There are lots of other arguments, perhaps, as to why these two particular glaciers have retreated, but I still remember hearing a presentation at the University of Delaware by Dr. Lonnie Thompson of Ohio State University, a glaciologist who presented a very broad and I thought very compelling case based on ice cores for the actual advance of climate change over many decades.
In fact, I see my colleague from Rhode Island has a photographic history of Grinnell Glacier in Montana's Glacier National Park, so the point I was just making in passing he is able to illustrate here. That is as of 10 years ago. The glacier has retreated even further from that. But this striking glacier from 1940 is now almost completely gone in just one generation.
This and so many other glaciers that were monuments in our national parks are today receded or altogether gone.
Well, I think we have to ask ourselves fundamentally, what is our path forward? We have heard from other Senators. Tim Kaine of Virginia spoke about the importance of innovation, and Angus King, the Senator from Maine, spoke about the importance of markets and of making sure our inventions and innovations in trying to solve these problems are also shared internationally. I think these are great and important insights.
One of the things I wanted to bring to the floor today first was insights from my own home State of Delaware, where our Governor, Jack Markell, impaneled a sea level rise advisory committee starting in 2010 that looked hard at how climate change might affect my home State.
At just 60 feet, Delaware has the lowest mean elevation of any State in the country, and that already makes it more susceptible to sea level rise than almost any State in the country. In my State of Delaware, we have seen and will continue to see the impact of climate change on our businesses, our communities, and our local environment. As the sea level rises, we are seeing the effects more and more.
Sea level rises essentially for two reasons. First, as the planet's ice sheets melt--the much larger sheets than Grinnell Glacier--they add to the amount of water in the ocean. Second, saltwater actually expands as it warms as well. So as the planet's average temperature has steadily risen, so too has the level of its saltwater seas.
The fact that the Earth's oceans are rising each year isn't new information. It has been rising as long as we have been keeping track. But what is really jarring is that rate of rise is increasing and increasing significantly. When the data was tracked from 1870 to 1930, the sea level was rising at a rate of 4 inches per 100 years. Over the next 60 years it rose at a rate of 8 inches per 100 years--more than double. In just the last 20 years the sea level has been rising at a strikingly more rapid rate of 12.5 inches per 100 years. The water is rising, and in Delaware it is rising fast.
The land itself in my State is also actually sinking. There is actually a documented vertical movement of the Earth's crust under the mid-Atlantic coast. It is called subsidence. It has been happening in Delaware slowly but gradually since the ice age at a pace of just 2 millimeters of elevation every year. I know that doesn't sound like a lot, but it adds up to another 4 inches over the century.
So we have the water rising and the land sinking, making climate change and sea level rise--specifically for my home State--a very real issue.
A wide array of scientists have studied this and its impact on Delaware, and they have developed three models for a future scenario. In the conservative model, by the year 2100 the sea level in Delaware will have risen about 1.5 feet. In another model, the water off Delaware rises another full meter. In another and the most disconcerting model, it is 1.5 meters or about 5 feet. Unfortunately, at present, this broad group of scientists--inside and outside of government--are estimating that is the most likely scenario.
Let's make this real. Here is a projection of these three different scenarios in one area of Delaware. This is Bowers Beach. This shows how now this is a well-established beach community. The most conservative model, we still have something of the land; in the middle, it is completely cut off here from the mainland; and then in the most likely, sadly, given the most current evidence, there is literally nothing left except a little sandbar out by itself in the Delaware Bay. That gives one example of why the difference between these three scenarios matters so much. Unfortunately, there is no scenario in which Bowers Beach is still a viable beachfront community by the end of this century. This beach community of Bowers Beach is very close to Dover Air Force Base and ends up underwater.
Now let's take a look at South Wilmington. The city in which I live is Wilmington, DE, and South Wilmington is a neighborhood in the largest city in our State. As the water rises in the Atlantic Ocean, it also rises up the Delaware Bay, the Delaware River, and the Christina River, which runs right through most of my home county, Newcastle County, and rises in the Peterson Wildlife Refuge too.
The impacts here are potentially devastating. We are talking about water 1.5 feet higher than what Delaware experienced during Superstorm Sandy--not for a brief storm surge but each and every day. Again, take a look at today the conservative, the middle, and the most likely, most aggressive scenario in which virtually all of South Wilmington is underwater by the end of this century. The calculation of whether we are hit with a half a meter, a full meter, or 1.5 meters of sea rise comes down to the rate of acceleration of climate change globally, and it leaves for us a central and so far unanswered question: whether we try to slow the rate at which climate change is affecting our planet and maybe somehow turn the tide. This is the part of climate change policy called mitigation.
Priority one in this strategy is cutting the emissions we are pumping into our atmosphere. To do that, we can and must diversify our energy sources and reduce our dependence on polluting fossil fuels. Clean energy technology, energy efficiency programs, public transportation, and more will help cut down on these emissions, but it will require a global effort in order to avoid or minimize local impacts.
The second part of climate change policy is adaptation based on an acceptance of the reality that our climate is changing and will have real effects on our planet and all of our communities. The truth is that even if we stopped all greenhouse gas emissions today--if we shut down powerplants, stopped driving cars, stopped using gas-powered farm equipment, trains, and ships, and all the rest--the amount of greenhouse gases, of CO2 and others already in the atmosphere would still take many years to dissipate. Changes in the world's climate are at this point inevitable. It is already happening and affecting communities, and we can expect these impacts to intensify as the rate of climate change continues to accelerate. We can modify our behavior to prevent those effects from being catastrophic. We can and should make better choices now to prevent disaster later.
In Delaware, for example, we have had two laws on the books for now 40 years that have helped us adapt. The first was championed in the 1970s by a Republican Governor, Russ Peterson, a hero of mine and of our Governor's and others. It is called the Coastal Zone Act, and passing it cost him his career in politics. It prohibited future industrial development on a long strip of coastal land, allowing the State and Federal government to preserve it and reduce the impacts of flooding and coastal erosion. Ultimately, in the long run, Governor Peterson has been proven a visionary in preserving this vital barrier all along Delaware's coast.
The second law empowered the State to protect and replenish the State's beaches, including the beaches on Delaware Bay, which are often overlooked. This has allowed our State to build a berm and dune system that protects infrastructure and protects property from being washed away.
More important than these significant landmark laws of 40 years ago, today, instead of running away from the science, Delaware's leaders have embraced it. The State agency that manages environmental issues for Delaware--known as DNREC and ably led by secretary Collin O'Mara-- has taken the lead on a governmentwide project to assess the State's vulnerability to sea level rise and, as I mentioned, recommend options for adaptation.
Delaware's Sea Level Rise Committee spent 18 months looking at 79 different statewide resources--roads, bridges, schools, fire stations, railroads, wetlands, people and their homes and businesses--and layered all of this onto maps to show just how far the water would reach at different models for sea level rise.
If the sea level does get to 1.5 meters, we lose more than 10 percent of our State. The water claims 20,000 residential properties, significant percentages of wetlands, farms, highways, and industrial sites. We would lose 21 miles of our Northeast corridor rail lines to flooding, shutting down the vital Northeast corridor that transports so many millions every year.
The Port of Wilmington would be rendered useless, nearly all the State's acreage of protected wetlands could be inundated, nearly three- quarters of our dams, dikes, and levees flooded out. In short, this scenario for our lowest-lying State would be devastating.
As Secretary O'Mara said:
We're looking at big risks for human health and safety, and
not just at the Delaware Bay beaches. We have big concerns
about [communities in Delaware]. It's much more complex than
just the bay beaches or a community here or there.
He is right. So once again, remember, we have two basic approaches to climate change policy: adaptation and mitigation.
Once Delaware compiled its 200-page vulnerability assessment on sea level rise, the committee got to work on an adaptation strategy to protect our State and came up with slightly more than 60 options and hosted a whole series of public meetings and townhalls to discuss it. We are now working on a broader vulnerability assessment to examine the full range of impacts from climate change, even beyond sea level rise-- changing temperatures, extreme weather, changes in precipitation-- impacts which will affect us and our neighbors.
Climate change will affect the distribution, abundance, and behavior of wildlife, as well as the diversity, structure, and function of our ecosystem. We are already seeing changes in natural patterns. As Senator Markey of Massachusetts commented earlier this evening, many commercial and recreational fish stocks along our east coast have moved northward by 20 to 200 miles over the past 40 years as ocean temperatures have increased. Scientists expect migratory species to be strongly affected by climate change, since animal migration is closely connected to climate factors, and migratory species use multiple habitats and resources during their migrations. These changes are impacting our own multimillion bird watching and waterfowl hunting, an important economic driver for us and critical parts of our heritage.
According to the draft National Climate Assessment released in 2013, our farmers are expected to initially adapt relatively well to the changing climate over the next 25 years. But later, as temperature increases and precipitation extremes get more intense, crop yields and production of poultry and livestock are expected to decline. More extreme weather events--drought and heavy downpours--will further reduce yields, damage soil, stress irrigation water supplies, and increase production costs. All in all, this is a fairly grim long-term outlook in the absence of decisive action.
I am proud of my State. Delaware was the first State to thoroughly assess the vulnerability of specific resources in as comprehensive a way as they have, and we are determined to confront these changes to our planet head on and to protect our communities and the way of life we have built.
I will briefly review. There is so much we can and should do here in Congress in a bipartisan way to lay the groundwork for the actions we have to take. We can improve our energy efficiency. We could take up and pass the bipartisan bill recently reintroduced by Senators Shaheen and Portman to increase the use of energy-efficient technology across all sectors in our society. The new version of the bill has 12 cosponsors--six Democrats and six Republicans--and includes 10 new commonsense amendments which would save consumers electricity and money, a small but meaningful start on a journey toward changing our direction on climate change. Or we could level the playing field and help new clean energy technologies get off the ground by giving them the same tax advantages currently utilized by fossil fuel projects. The bipartisan Master Limited Partnerships Parity Act--which I am proud to cosponsor with my colleagues Senators Moran, Stabenow, Murkowski, Landrieu, and Collins, Democrats and Republicans working together-- would level the playing field for renewables and give them and other new technologies a fighting chance in our energy market.
There are so many other steps we could do in combination, if we would but get past this endless, pointless debate which has long been resolved in the halls of science, and move forward in a way which better serves our country and our world.
The bottom line is that our climate is changing. We know this. With this knowledge comes the responsibility to reduce our emissions, to mitigate the impacts, and prepare for and take action to deal with the coming changes.
As I reflect on our own responsibilities as Senators, I am in part moved to respond to the challenge of climate change--not just because it is an environmental issue, an economic issue, a regional issue or global issue, but it is also for me and for many others a faith issue. It is a question of how we carry out our responsibility to be good stewards of God's creation, to be those Senators we are called to be each from our own traditions who stand up and do what is right, not just for the short term, not just for the concerns of the day, but for the long term.
As I move toward my close, I will share with those in the Chamber and watching one of the things most encouraging to me as I have reflected on the change in the climate change movement over recent years is it has begun to draw support from all across the theological spectrum. There was last year, July of 2013, a letter sent to Speaker Boehner, Majority Leader Reid, and all Members of Congress by 200 self- identified Christian evangelical scientists from both religious and secular universities all across the United States, a powerful and incisive letter which says:
As evangelical scientists and academics, we understand
climate change is real and action is urgently needed. All of
God's Creation--human and our environment--is groaning under
the weight of our uncontrolled use of fossil fuels, bringing
on a warming planet, melting ice, and rising seas.
I urge any watching to consider reading it. It is posted on line. It goes on to quote Christian Scripture at length in making the case we have an obligation, if we are concerned about our neighbors and about the least of these in this world, to take on the challenge of making sure we are good stewards.
Those of the Roman Catholic faith might be inspired by Pope Francis, who has taken the name of the patron saint of animals and the environment, and recently issued a call for all people to be protectors of creation.
Last, I might read from a letter issued by the president of the National Association of Evangelicals, a group not commonly known for their close alignment with my party. Leith Anderson wrote in a letter in 2011:
While others debate the science and politics of climate
change, my thoughts go to the poor people who are neither
scientists nor politicians. They will never study carbon
dioxide in the air or acidification of the ocean. But they
will suffer from dry wells in the Sahel of Africa and floods
along the coasts of Bangladesh. Their crops will fail while
our supermarkets remain full. They will suffer while we
study.
This couldn't be more true. I urge all of us in this Chamber to reflect on whatever traditions sustain and bring us here that we have an obligation to those who sleep soundly in our homes now, to those from our home States around the country, to stand up and take action, to look clearly at the challenge which lies in front of us and to act in the best traditions of this body and of this Nation, to be good stewards of creation and to stand up to the challenges of this time.
