Mississippi River Mayors Come Together To Consider Climate Change
A group a mayors living along the Mississippi River has plans to collaborate with international leaders, with an eye toward playing a bigger role in global talks surrounding climate change.
Mayors with the Mississippi River Cities and Towns Initiative will be working more closely with the Netherlands, learning what actions have been taken to protect the Rhine River from climate change.
The group is also initiating discussions with people living along the Amazon, Euphrates, Yellow, Paraná, Danube, Volga, and Ganges rivers.
MRCTI director Colin Wellenkamp said the Mississippi River Valley is the most agriculturally productive zone on the planet and working with those other major food-producing regions is a necessity.
“This is not going to be not just about flooding and water management, it’s going to be about the future of our food supply,” Wellenkamp said. “Climate disruption is a major component of that and so far, that part of the conversation really hasn’t been emphasized.”
Mayors from La Crosse, Onalaska, Prairie du Chien, and Prescott are involved in the initiative, which will send a delegation of mayors to the Conference of the Parties to the United Nations Framework Convention on Climate Change, also known as COP21, later this year.
The MRCTI also recently praised sections of the president’s proposed budget for offering more funding for flooding and disasters.
President Obama proposed funding the Federal Emergency Management Agency’s Pre-Disaster Mitigation Grant program at $200 million, which is a record high.
In La Crosse, this program has been used to flood-proof and remove homes built in the city’s floodplain.
Mayor Tim Kabat and fellow members of the Mississippi River Cities and Towns Initiative met with members of Congress this week, encouraging them to maintain the funding. Kabat said the grants can save money in the long run.
“You do the investment and the project in the front end and prevent a lot of the emergency situations on the back end,” Kabat said.
Kabat said, in the future, these grants could be used to restore the city’s marsh.
The mayors also hope to see funding go up for National Flood Insurance Program Risk Mapping.
President Obama’s Executive Order Committing Federal Government to Cutting Its Greenhouse Gas Emissions
President Barack Obama signed an executive order on Thursday committing the federal government to cutting its own emissions 40 percent by 2025 and pledging to increase the amount of renewable energy used by federal agencies to 30 percent.
-
[This is a good addition but still not nearly enough. States and everyday Americans all have to greatly reduce the things they do that contribute to their daily and annual greenhouse gas emissions, as does the rest of the world. The U.S. still has the highest per capita GHG emissions. Forty percent of world travel by air (a large emitter of GHGs) is by American recreation and business travel pursuits. This has to change! Click on: “About this Blog” to read about how our government really could help make this happen – Power to the People]
The executive order builds on a previous administration directive to cut emissions from federal agencies 28 percent by 2020, compared with 2008 levels. “We are well on our way to meet that goal,” Brian Deese, senior adviser to the president, said in a call with reporters Thursday. “That’s what’s motivating us today to chart out a new and even more aggressive goal going forward.”
The administration is also setting a goal of cutting the per-mile emissions from the agencies’ vehicle fleet 30 percent, it said. It estimates the total commitment across the federal agencies will save taxpayers $18 billion — funds that won’t be spent on energy.
Christy Goldfuss, managing director of the Council on Environmental Quality, said that by the end of 2014, the federal government had cut emissions 17 percent since 2008, putting it well on the way to meeting Obama’s earlier goal. Much of that has come through energy efficiency improvements in federal buildings and with the installation of renewables.
As of the end of 2014, renewable energy accounted for 9 percent of the federal government’s energy use, and Thursday’s directive wants to increase that to 30 percent by 2025. The Department of Defense has set its own goal of deploying 3 gigawatts of solar energy on its installations around the world by 2025.
The federal government is the single largest energy user in the United States, Goldfuss said, with 360,000 buildings and 650,000 vehicles. “Not only is our footprint expansive, our impact is as well,” she said.
The administration also argued that the push to reduce emissions in the federal government has effects across the private sector as well. To that end, the administration also released a scorecard to track emissions from major federal contractors such as Lockheed Martin, Boeing and General Dynamics, which the administration is also calling on to make reductions.
The White House estimates that with reductions from the agency and those of private suppliers, the administration can cut greenhouse gas emissions by 26 million metric tons in the next 10 years.
“These goals will make sure the federal government is leading by example and pushing the envelope on cutting emissions,” said Deese, adding that it will “demonstrate that we are going to stay on offense in pushing our clean energy and climate change objectives.”
‘Green The Church’ Seeks To Mobilize Black Churches On Climate Change

Leaders of the “Green The Church” movement launched a new effort this week to help 1,000 African-American congregations take action on climate change.
Green The Church, its organizers said, “aims to bring the benefits of sustainability directly to black communities.” It includes a partnership between Green For All, the California-based environment and social justice organization, and the U.S. Green Building Council, which will work with churches on renewable energy and energy efficiency projects. It also seeks to “tap into the power of the African-American church as a moral leader and a force for social change,” through education and outreach to millions of black church-goers across the country.
“The black church has always joined hands with other faith traditions and stood on the front lines, as they did on ‘Bloody Sunday’ in Selma 50 years ago,” the Rev. Dr. Ambrose Carroll, a California-based pastor who founded Green The Church, said in a call with reporters Thursday. “So they must with climate change.”
Carroll said a lot of progress, such as efficiency retrofits and urban farming initiatives, can be made at the churches themselves. “We may not own a lot of real estate, but we do own church buildings,” he said.
The Rev. Dr. Otis Moss III, the senior pastor at Chicago’s Trinity United Church of Christ, said his church has already purchased 27 acres of land on which to build a new urban farm, housing, and health, education, and wellness centers. “It will be green from the ground up,” he said, adding that they want to promote the message that it’s “not only, ‘Say it loud, I’m black and I’m proud,’ but, ‘Say it loud, I’m green and I’m proud.'”
Green For All said it found in recent polling that three-quarters of minority voters expressed an interest in climate change and wanted to know more about it. Sixty-eight percent said they thought climate change threatens their communities.
“We get hit first and worst by everything negative in the pollution-based economy,” said Van Jones, the founder of Green For All and a current CNN contributor. Green The Church will advocate for “equal protection from the worst, and access to the best.”

John Kerry Calls Out Florida’s Ban On Saying ‘Climate Change’
Secretary of State John Kerry, challenging climate change deniers to face reality, not-so-subtly called out Florida Gov. Rick Scott’s (R) administration on Thursday for banning the term “climate change” from all government communications.
“We literally do not have the time to waste debating whether we can say ‘climate change,'” Kerry said in a speech hosted by the Atlantic Council. “We have to talk about how we solve climate change. Because no matter how much people want to bury their heads in the sand, it will not alter the fact that 97 percent of peer-reviewed climate studies confirm that climate change is happening and that human activity is largely responsible.”
News of Florida’a ban, which also extends to the term “global warming,” came to light over the weekend in a report by the Florida Center for Investigative Reporting.
Scott in May declined to say whether he believed in climate change, but has said repeatedly that he is is not convinced by the science.
Such thinking is far too prevalent in Washington, and politicians who ignore the facts will not be remembered favorably by those who will face global warming’s worst perils, Kerry said in his speech.
“If we fail, future generations will not and should not forgive those who ignore this moment, no matter their reasoning,” Kerry said. “Future generations will judge our effort not just as a policy failure, but as a collective moral failure of historic consequence. And they will want to know how world leaders could possibly have been so blind or so ignorant or so ideological or so dysfunctional and, frankly, so stubborn.”
Kerry called for transitioning away from “dirty sources of energy.” But, as Politico noted, he didn’t mention whether he would approve the proposed Keystone XL oil pipeline, which would link Canada’s oil sands to the U.S. Gulf Coast. The project, which needs State Department approval to cross an international border, has been awaiting Kerry’s decision since early February. He will hand his recommendation to President Barack Obama, who will make the final decision on the project.
Environmental groups opposed to the pipeline said Kerry’s failure to mention it may be a positive sign.
“While Kerry didn’t bring up Keystone, he sure brought up more and more reasons why it should be rejected,” Sierra Club legislative director Melinda Pierce told Politico. “And he’s absolutely right: Burning fossil fuels has long-term costs that have to be at the front of our minds when evaluating both the pipeline project and development of the tar sands.”

Emperor Walker Wearing No Clothes When It Comes to Wisconsin’s Natural Resources
Actually, this emperor has no clothes.
Wisconsin citizens have got to realize that Wisconsin’s governor has not had the best interests of the state at heart when it comes to natural resources issues, including the effects of rising greenhouse gas concentrations in the atmosphere’s significance to Wisconsin’s natural, economic and human resources in the absence of timely action by their governmental officials.
This politician looks only ahead to the next election. Our part-time governor has his attention turned to Iowa, New Hampshire and any road leading to Washington, D.C.
His tracks are the proposed budget that will leave scars on the state.
For a state with the legacy of people like Aldo Leopold, John Muir, Gaylord Nelson, and Warren Knowles, it is an embarrassment that Gov. Walker would submit a budget that:
• Strips the Natural Resources board of its authority, making it advisory only to the DNR – leaving all decisions up to the DNR secretary;
• Eliminates 18 research scientists from the DNR Sciences Services Bureau;
• Eliminates environmental education programs;
• Places a moratorium on land buying through the Stewardship Fund.
The problem is that politicians care about money brought into their campaigns, and getting re-elected.
That is why the Natural Resources Board was established originally: to keep natural resources governance at arm’s length from politicians. The NRB (citizens who in the past came together to put natural interests foremost), can make decisions taking into account biological and sociological information.
The NRB was also charged with hiring a DNR secretary, but Tommy Thompson and Jim Doyle looked to their self-interest and changed a system that worked well since 1927.
Now Scott Walker has manipulated the system, put politicians in charge of the DNR, silenced scientists, and changed agency priorities from natural resource protection to job creation.
How long can people who hunt, fish, trap, bird watch, hike, camp, and enjoy the state’s scenery, sit on their hands while the governor trashes our state?

Note: “Emperor’s New Clothes” is an old children’s story by Hans Christian Andersen about an emperor who pays a lot of money for some new magic clothes which can only be seen by wise people. The clothes do not really exist, but the emperor does not admit he cannot see them, because he does not want to seem stupid. Everyone else pretends to see the clothes too, until a child shouts, “The Emperor has no clothes on!”
Wisconsin Legislature Votes to Call “Extraordinary Sessions” for Wrong Reasons
Organizing committees of both the Wisconsin Senate and Wisconsin Assembly called both houses of the Wisconsin legislature into extraordinary sessions this week to pass a “right-to-work” bill, making it illegal for employers and labor unions to charge their employees and any new employees union dues as a condition of accepting employment. The Wisconsin State Journal reported in today’s newspaper edition that the full Senate could vote on this highly charged legislation (Senate Bill 44) as early as Wednesday and the Wisconsin Assembly could vote on this legislation (AB 61) as soon as Monday.
Governor Scott Walker has said he would sign the bill into law.
The Senate and Assembly organizing committees ought have called their “extraordinary” sessions to address what the State of Wisconsin ought do to protect its citizens from global warming and climate change instead. Greenhouse gas emissions, global warming and climate change are far more significant to the future of Wisconsin than are unions charging union dues in the state.
Governor Scott Walker Punts on Taking On Climate Change in Wisconsin’s State Budget and Other Walker Administration Decisions
While other countries and U.S. states struggle with the deadly and extremely negative economic costs of dangerous storms made worse by warming oceans and rising sea levels caused by increasing greenhouse gases concentrations in the atmosphere, Wisconsin Governor Scott Walker has taken a pass on including anything in his two-year budget about how or to what degree the State of Wisconsin might reduce its annual greenhouse gases emissions and better adapt to the changing climate predicted for the future in Wisconsin. Governor Walker’s two-year state budget was forwarded to the Wisconsin Legislature earlier this month for adoption by July 1, 2015.
Much of what the governor’s budget proposes for the state will exacerbate the world’s chances of ever reducing climate change, or global warming, to a safe level. Scientists now say the changing climate around the world (global warming) is overwhelmingly human-caused and will be disastrous for the planet if the amounts of fossil fuels (coal, oil, natural gas) we are now burning are not significantly reduced and in a timely manner – now! – worldwide, and deforestation, over has been done over the last 100 – 150 years is stopped. Forests sequester carbon dioxide (CO2) as they grow, which is also the most abundant of the greenhouse gases emitted during fuel combustion.
While Wisconsin did experience a costly drought two years ago, and suffered through two recent killing heat waves in 1995 and 2011, the state has generally been spared from such massive destruction and loss of life as occurred in the Philippine Islands caused by Typhoon Haiyan U.S. states under hit by Hurricanes Sandy Sandy, Katrina and Ike, Hurricane Irene and increasing torrential rains and flooding around the world, heavier snowfalls, and long lasting droughts in California, other western states, and other areas around the world.
The economic costs of these catastrophes, especially those occurring in the United States, negatively effects all states in the U.S. through increased prices of goods, higher insurance rates, and the overall health of the U.S. economy.
Instead of addressing the inevitable economic and environmental effects of climate change and its causes in Wisconsin, Governor Walker instead chose to include in his two year budget proposal for the state many action items that, if enacted into law by the Wisconsin Legislature will, without question, add to the already abhorrently high human, economic and environmental costs of change climate here in Wisconsin and throughout the rest of the world. For example, Governor Walker’s two-year budget, which would begin taking effect in July 2015, expands numerous major highways in the state to increase their capacity to accommodate increased driving of cars and trucks, the vast majority of which burn fossil fuels. The governor’s budget proposes to contribute millions of dollars in state bonding to help the privately owned Milwaukee Bucks build a new arena for NBA games, games that require thousands of miles of jet travel each year for each visiting team as well as their fans and supporting personnel, adding measurably to rising volumes of greenhouse gases linked with global warming.
Furthermore, by not proposing other actions, many additional sources of greenhouse gases and pollution will continue and undoubtedly increase significantly in the next two years under the Walker administration and the current Republican legislature. Due to the lower price of crude oil, prices of fuel at the pump have dropped, leading to the purchase of less fuel efficient SUVs and trucks.
Americans and Wisconsinites need to drastically reduce their annual driving miles, and Governor Walker’s budget should have included positive financial benefits to encourage people to drive fewer and fewer miles each year, and compensate those individuals and Wisconsin families who manage to drive less miles, annually, than average – especially those individuals and families who don’t drive personal automobiles or fly airplanes (jet fuel is a fossil fuel and jets burn tons of fuel on each trip) during the year. The emission of greenhouse gases (GHGs) to the atmosphere from motorized transportation, jets, other internal combustion engines, as well as GHGs emitted from coal, oil, and natural gas burning power plants and household and business furnaces is “cumulative”, meaning the various emission of those gases accumulate in the atmosphere over time, rising to higher and higher levels of concentration in the atmosphere.
Scientists the world over have reached a level of consensus that the amount of GHGs present in the atmosphere are becoming increasingly of concern, more threatening each year that global warming worsens. Eventually, global warming could reach, or is close to reaching, its “tipping point” in the atmosphere – a level of accumulation of GHGs in the atmosphere after which the earth’s natural systems could keep adding more and more GHGs into the atmosphere, the point at which continued warming would become inevitable, regardless of what we humans do to reduce our GHG emissions. For example, as the permafrost region of the planet thaws (1/5 of earth’s surface exists in the form of permafrost), the GHG methane is released from the rotting permafrost. Methane is a much more potent GHG than CO2, and when the permafrost begins to thaw extensively, it will be releasing massive amounts of methane to the atmosphere, This would make matters much worse, because global warming would become less responsive, if responsive at all, to the amount of GHGs we humans cause to be emitted (or not to be emitted).
Positive Incentives Plan Wages Three-Prong-Attack Against Climate Change
Please refer to “About this Blog” before proceeding.
The planet Venus is on the left; Earth is on the right. Nobody wants to see Earth go the route its that its commonly called twin planet Venus took, eons ago. You see Venus once had oceans of water, too, just like Earth does. But something went very wrong on the surface of Venus (possibly it is because the Sun got hotter), which started a “runaway greenhouse effect”. The oceans of water Venus once had boiled away. As temperatures began rising ocean water converted to water vapor, also a strong greenhouse gas. The water vapor increased the effectiveness of heat trapping and accelerated the greenhouse effect, which caused the temperature at the surface to rise further, thus causing the oceans to evaporate faster, etc., etc. This type of runaway is also called a “positive feedback loop”. When the oceans were gone the atmosphere finally stabilized at a much higher temperature and at much higher density, making the planet uninhabitable.
The sobering warning for us is obvious: we have to be extremely concerned about processes such as burning of fossil fuels in large volumes that might have the potential to trigger a runaway greenhouse effect and produce on the Earth atmospheric conditions that are incapable of supporting life.
That is why it is so essential that we initiate actions now, worldwide, to curb all forms of unnecessary activity that causes the greenhouse effect in our atmosphere to strengthen (meaning an increase concentrations of greenhouse gases). Carbon dioxide (CO2), a greenhouse gas, has increased in concentration in the atmosphere from 280 parts per million (ppm) in the 1880’s to 400 ppm today – mainly the result of humans burning coal, oil. and natural gas, the combustion producing significant amounts of (invisible) CO2.
As a result, the global average annual temperature of the Earth at the surface has risen, the temperature of Earth’s oceans have been increasing and, as a result of the ice melting off of the island of Greenland, the continent of Antarctica, and water runs down the mountainous glaciers on practically all the continents, and the property of the thermal expansion of water, Earth’s oceans levels are rising.
Meanwhile, the Earth’s once solid permafrost region, which is approximately 1/5 of the Earth’s surface, is now thawing in many places, decomposing,and releasing methane to the atmosphere, a greenhouse gas 37 times as strong as CO2 in trapping heat.
Furthermore, replacement of large areas of ice and white snow surface (ice cap) on the Arctic Ocean means the open Arctic ocean water absorbs more of the radiant heat from the Sun, causing the ice and snow to melt even faster still, an so on. If it were not for the vast amounts of ice in the Arctic Ocean, the water would warm even faster.
It is essential that people and businesses, the world over, especially those in countries burning vast quantities of fossil fuels, in power generation, motorized transportation and jet travel, for human travel and shipping, find alternatives that don’t burn fossil fuels for their pursuits. Presently, citizens from the United States fly 40% more than citizens from other countries, and more U.S. citizens are buying gas guzzling SUVs and pickup trucks than more fuel efficient vehicles – because gas is “cheap” again, They remain apathetic about global warming, or are members of the “Earth is flat” society. As John Lennon once said, “apathy is it”. The Earth is also round. Above all, we need to Conserve, NOW!
Wisconsin Must Join the All Out World Effort to Fight Global Climate Change Without Delay, BEFORE Time Runs Out
Wisconsin has traditionally prided itself as being a state that “cares”. Wisconsin residents care about its wild and domestic animals, its fish, birds and butterflies; its plants, trees, and its forests; its tens of thousands of lakes, streams and rivers, and the quality of its wetlands, groundwater and air; its mighty bluffs and gorges, its remaining prairies, and the state’s overall majestic scenic beauty.
Wisconsin has traditionally had a strong manufacturing economy, a top notch agricultural industry, a public education system second to none, a world class university system, and an equally top notch private schools, colleges, and other educational institutions. Wisconsin also boasts an excellent highway, airport, and bicycle transportation system, and communities that are walking and wheelchair friendly. It has always held all visitors to the state in high regards and treated them with respect the production and sustainability of its farms, the well being of its human population, without regard for race, heritage or creed. Wisconsinites treat visitors to their state with respect and dignity,satisfaction of its visitors and transients alike, and, perhaps above all, in leaving its land, water and its economy better condition than they received it. In a nutshell, that’s a statement of Wisconsin’s traditions and value, as I have come to know them.
Wisconsin residents often boast, and rightly so, that Wisconsin was the home of such renown conservationists and humanists as John Muir, Aldo Leopold, Senator Gaylord Nelson, Midge Miller and Vel Phillips. In the 1970s, Wisconsin was emulated by other states as the state to look at for developing effective environmental protection regulations to safeguard its treasures. With Wisconsin Departmental Resource Secretary Anthony “Tony” Earl at the helm, who would later become Wisconsin’s governor, and George “Knute” Knudson as its chief naturalist, Wisconsin natural resources were in good hands.
It is no exaggeration to say that all this is at risk the longer our Wisconsin Legislature, our governor, other state legislatures and governors, and the people’s representatives in the United States Congress continue to kick the issue of excess fossil fuel burning and greenhouse gas production by Americans down the road. What we don’t need is more highway development and expansion and more airport capacity expansion that encourage even more fossil fuel burning by the public. What we don’t need is more trade with distant countries that requires more fuel for shipping and flying. What we don’t need are more coal and natural gas burning power plants and the thousands of miles of high voltage transmission lines that go with them, and not Wisconsin power companies who restructure their rates in favor of more fossil fuel burning, thus discouraging their customers from investing in solar energy panels for their homes and businesses, and having the governor’s appointed Wisconsin Public Service Commission (the PSC) “rubber stamps” the fossil-fuel-dependent utilities’ proposals.
We are wasting valuable time and money by not relying less and less on fossil fuel dependent energy, and more on either energy conservation or on conversion to solar and wind generated power, in our homes, businesses and institutions; and that we desperately need to reduce aggregate driving and flying, which rely almost exclusively on burning fossil fuels that, when subject to combustion, release large quantities of greenhouse gases, especially carbon dioxide (CO2), to the atmosphere. Most of the greenhouse gases, such as CO2, remain in the atmosphere for centuries, accumulating to increasingly more ominous concentration levels, or they get absorbed in the oceans, making the earth’s ocean water more acidic, harming the biological species in the oceans.
But scientists the world over are in agreement that the rising concentrations of greenhouse gases from significantly increased fossil fuel burning by humans since the time of the Industrial Revolution (early 1800’s) have remained in earth’s atmosphere, trapping more and more of the Sun’s radiant energy and changing it into heat energy, causing the earth’s surface to warm, melting more of the polar ice caps and mountain glaciers, causing the vast permafrost region to thaw, releasing more and more methane gas, another greenhouse gas that’s known to have 37 times the heat-trapping power of CO2.
Scientists don’t know when global warming could begin accelerating, but it could be any day now. What they do know is that there are higher concentrations of greenhouse gases in the atmosphere now to push global surface temperatures much higher than what we have experienced thus far. Time is of the essence for the world’s populations who are relying on fossil fuel burning for energy to stop adding even higher concentration levels of greenhouse gases to the atmosphere, risking setting off positive feedback mechanisms in the system that could worsen the situation and amplify the weather extremes global warming has already caused in earth’s climate.
Higher Sea Level Projections Required Along U.S. Coasts
President Barack Obama issued an executive order on Friday,January 30, 2015, directing federal, state and local agencies to incorporate projections for sea level rise in planning and construction along the coasts.
The new Federal Flood Risk Management Standard requires that all federally funded projects located in floodplains, including buildings and roads, be built to withstand flooding. The requirement, the White House said in a release Friday, would “reduce the risk and cost of future flood disasters” and “help ensure federal projects last as long as intended.”
“It is the policy of the United States to improve the resilience of communities and Federal assets against the impacts of flooding,” the order states. “These impacts are anticipated to increase over time due to the effects of climate change and other threats. Losses caused by flooding affect the environment, our economic prosperity, and public health and safety, each of which affects our national security.”
According to the National Oceanic and Atmospheric Administration (NOAA), the U.S. can expect to see up to two feet of sea level rise by the end of the century, largely due to climate change. Warmer temperatures are causing thermal expansion in the oceans, as well as the melting of sea ice, which is pushing sea levels higher globally. A study from the U.S. Geological Survey found that half of the U.S. coastline is at high or very high risk of impacts due to sea level rise.
This is a significant shift, as agencies have typically used historic information on sea level and flooding for planning, rather than future projections. The order directs agencies to use the “best-available, actionable hydrologic and hydraulic data and methods that integrate current and future changes in flooding based on climate science” when evaluating what is in the flood plain. They also have the option of building 2 feet above current base flood elevations for “non-critical” infrastructure and 3 feet above for “critical” infrastructure, or building to the standard of the 500-year flood (a flood with an estimated 0.2 percent chance of happening in any given year).
The Task Force on Climate Preparedness and Resilience released a set of recommendations last November, and establishing this type of guideline was among them. Most coastal regions of the United States will see 30 or more days of flooding by 2050 as a result of sea level rise, according to NOAA predictions.
NOAA’s researchers looked at the anticipated frequency of what the National Weather Service considers nuisance flooding, which are floods that are 1 to 2 feet over the regular local high tide and are enough to cause problems but not pose active threats to human life. Some areas of the U.S. are already seeing increased flooding, the researchers said, and it’s only going to get worse.
“Coastal communities are beginning to experience sunny-day nuisance or urban flooding, much more so than in decades past. This is due to sea level rise,” William Sweet, an oceanographer at NOAA’s Center for Operational Oceanographic Products and Services and the report’s coauthor, said in a statement. “Unfortunately, once impacts are noticed, they will become commonplace rather quickly.”
The research was published in the American Geophysical Union’s peer-reviewed online journal Earth’s Future. The projections are based on data from NOAA tidal stations with at least a 50-year continuous record. Warming global temperatures cause thermal expansion of the oceans and also melt ice sheets, leading to sea level rise. The researchers also note that while much of the rise is fueled by climate change, there are parts of the country where the land is sinking as well, adding to the challenge.
The low-end expectations for sea level rise from the researchers’ analysis project a 1.5 feet increase by 2100. Sweet said that within 30 to 40 years even that low-end projection would increase flooding in many areas “to a point requiring an active and potentially costly response.” And by the end of the century, Sweet said, “there will be near-daily nuisance flooding in most of the locations that we reviewed.” The high-end projections of sea level rise they looked at would put the increase much higher, at 4 feet.
Among the places that can expect flooding sooner rather than later, according to the study: Boston, New York City, Philadelphia, Baltimore, the District of Columbia, San Diego and San Francisco.
