Leadership: The auto industry’s missing ingredient

By Jason Mathers / Published: January 16, 2018

The automotive industry’s capacity for innovation and marketing are on full display this month. Between the Consumer Electronic Show and the North American International Auto Show, every day brings a new story about the rapid development of vehicle technology. The industry possesses the know-how and ability to deliver on the zero-emissions future if it wants to.

Behind the headlines of engineering feats and product plans, though, is a disturbing fact. The industry is undermining its own innovation. It’s doing this through a campaign to dramatically weaken the central tool we have to move cleaner technology into the fleet – protective greenhouse gas reduction and fuel efficiency standards for new cars and passenger trucks.

Well-designed federal standards foster the deployment of fuel saving solutions. With the certainty of long-term standards in place, manufacturers are able to make the necessary investments to scale these solutions into the fleet. Scaled production further drives down costs, enhancing automaker profitability and consumer payback.

This cycle has been in full view over the past several years as automakers have brought to market ever more efficient vehicles with record sales and strong profitability. An exhaustive technical analysis completed by the U.S. Environmental Protection Agency, National Highway Traffic Safety Administration and California Air Resources Board found that automakers were well positioned to deliver even more fuel efficiency and emissions progress in the years ahead.

With this robust technical underpinning, the U.S. Environmental Protection Agency (EPA) issued a determination to maintain the existing 2022 to 2025 standards. Back in 2012, EPA finalized these standards with the broad support of the automotive industry. But fast forward to today, and the automotive industry is pushing for the Trump Administration to reconsider this determination.

This has set up a year of incongruity where the industry’s position that the standards need to be re-examined are consistently contradicted by its product announcements. In just this past year, automakers have made the following announcements:

  • Daimler AG announced a billion dollar investment to build electric vehicles in the U.S. with production starting in the early 2020’s.
  • BMW reached 100,000 in global electric vehicle sales while promising a dozen models of electric vehicles by 2025.
  • Toyota committed to having at least 10 models of all-electric vehicles by the early 2020’s.
  • Mazda promoted an engine breakthrough that could improve efficiency by up to 30 percent, and is planning to deploy the new engine in 2019.
  • GM laid out a bold vision for a “zero crashes, zero emissions, and zero congestion” future, announced plans for 20 new electric vehicles by 2023 – including two by 2019, and rolled out the acclaimed Chevy Bolt across the U.S.
  • Ford publicized its intention to have an electric vehicle with a range of 300 miles on the market by 2020.

These are not public announcements most automakers make lightly. They make them with high confidence in their ability to meet them.

As amazing as these announcements are, none of them are even necessary to meet the vehicle greenhouse gas standards that EPA finalized in 2012 and affirmed last year. The industry is already poised to meet these standards with broader adoption of more conventional technologies.

The impressive innovation in advanced engine design and electrification – which the industry clearly believes will start to scale over the next few years – will make the standards even more attainable.

Yet, despite the remarkable recent record of innovation and the significant investments made in developing a new generation of clean vehicle solutions, the automotive industry – through its trade associations – has chosen a path to weaken our existing emissions standards and has stayed silent as EPA Administrator Scott Pruitt has threatened California’s own protective vehicle emission standards.

The industry’s actions are contradictory and concerning. Yet, there is still time for automakers to choose a different path – one that looks to the future and seeks to build a new round of protective standards that rewards the industry’s innovation, lowers costs for families and protects human health and the environment.

As the announcements are made over the coming days, we should also be listening to hear if any automakers are willing to match their record on innovation with what the industry most needs now – leadership.

Trump Administration misleads Americans about the cost of climate pollution

By Susanne Brooks / Published: October 25, 2017

The Trump Administration is attempting to justify the rollback of crucial environmental and health protections by vastly undervaluing the costs of climate change.

The latest safeguards under attack are the Clean Power Plan, the nation’s first-ever limits on carbon pollution from existing power plants, and the Bureau of Land Management’s vital standards to reduce wasted natural gas from oil and gas facilities on public and tribal lands. They would have health, environmental, and economic benefits worth an estimated billions of dollars annually. But you wouldn’t know it from reading the Administration’s recently revised documents – because of a series of deceptive accounting tricks, including efforts aimed at obscuring the benefits of reducing carbon pollution.

The Trump Administration has used discredited methods to eviscerate the social cost of carbon — an estimate of the costs that carbon pollution inflicts on the public, represented as the dollar value of the total damages from emitting one ton of carbon dioxide into the earth’s atmosphere.

The social cost of carbon is a tool that helps ensure that policymakers consider the health, environmental and economic benefits of avoiding extreme weather, rising temperatures and intensifying smog when they make decisions that affect climate pollution.

Climate change harms businesses, families, governments and taxpayers through rising health care costs, destruction of property, increased food prices and more — so it’s common sense that we should properly account for the value of avoiding these harmful outcomes. But the Trump Administration has systematically undermined and attacked the well-established science of climate change – including the social cost of carbon, which has had a target on its back for a while now.

The most up-to-date estimates of the social costs of carbon were developed by an Interagency Working Group (IWG) of experts from a dozen federal agencies. They were developed through a transparent and rigorous process based on the latest peer-reviewed science and economics, and with input from the public and the National Academy of Sciences.

But in March, President Trump cast aside the results of this thorough and consultative process. He issued an executive order aimed at discrediting the IWG estimates, withdrawing them as government policy, and directing federal agencies to pick their own metric.

The executive order leaves federal agencies to fend for themselves without specific guidance, opens the door to extensive legal challenges, and effectively sets up agencies to cook the books to serve the Administration’s goals.

That’s exactly what EPA Administrator Scott Pruitt and Department of the Interior Secretary Ryan Zinke just did – releasing benefit-cost analyses that massively undervalue the costs of carbon pollution, radically reducing the estimates by up to 97 percent.

The Trump Administration would have us believe that the costs of carbon pollution are near zero. The Administration’s new estimates are only a couple dollars per ton of carbon dioxide – about as much as a cup of coffee or a bus ticket.

Sadly, communities around the country are already seeing just how wrong that is. From longer wildfire seasons to more intense hurricanes, the American public is already bearing the enormous costs of climate change.

Even the IWG estimates – roughly $50 per ton of carbon dioxide based on year 2020 emissions – are almost certainly a conservative lower bound since they do not yet reflect many different types of climate impacts.

A closer look at the Administration’s deceptive math 

There are two major flaws in the Administration’s drastically reduced estimates, both of which fly in the face of established science and economic principles in service of obscuring the very real benefits of climate action.

First, the reduced estimates ignore that carbon emissions are a global pollutant, so they omit important categories of climate change impacts on the United States.

Second, they shortchange the harm to our children and future generations from climate change.

The so-called “domestic-only” estimate

Since the impacts of carbon pollution are felt globally regardless of where the emissions come from, leading researchers and the IWG have appropriately focused on accounting for that full global impact.

In contrast, the Administration’s revised estimates claim to consider “domestic-only” impacts to the United States. But that title is a misnomer – the Administration’s flawed approach ignores important categories of impacts that affect the American public. Climate impacts beyond our borders have costly repercussions for U.S. citizens in the form of changing global migration patterns, economic and political destabilization, and other “spillover” effects.

The National Academy of Sciences specifically rejected the approach the Administration is taking in a report released earlier this year, concluding that:

[C]limate damages to the United States cannot be accurately characterized without accounting for consequences outside U.S. borders.

Economist Richard Newell – president of the think tank Resources for the Future, which is leading an effort to implement the Nation Academy of Sciences’ recommendations to update the social cost of carbon estimates – has criticized the Administration’s approach, saying that considering only direct domestic impacts is:

[U]nnecessarily constrained and unwise for addressing inherently global pollutants like greenhouse gases.

The use of a “domestic-only” number also harms Americans because it undervalues the cost of climate pollution and encourages other countries to similarly undervalue – and over-emit – this pollution.

More than half a dozen leading experts argue:

[The] United States benefits tremendously if other countries set policy based on global rather than local effects.

They also point out that the use of a global estimate can encourage reciprocal climate action elsewhere. For instance, the Canadian government incorporated the U.S. IWG value in its own policy analysis.

Undervaluing the impacts on children and future generations

The Administration’s estimates also use a sharply lower value for the benefits that today’s carbon reductions provide to children and future generations. Again, this is in direct conflict with the weight of expert opinion that supports valuing these impacts even more than we did before the Trump Administration.

The Administration’s estimates “discount” future impacts at 7 percent – a rate significantly higher than the 3 percent central rate of the IWG, and one that is wholly unsupported by the economics literature when it comes to the long-lived intergenerational effects of carbon pollution.

A growing consensus among leading economists supports lower or declining discount rates, as does the Council of Economic Advisors.

As Richard Newell of Resources for the Future points out:

Practically speaking, the use of such a high discount rate means that the effects of our actions on future generations are largely unaccounted for in the new analysis.

In other words, the Administration’s estimates reveal just how little they value protecting American children and generations to come.

The social cost of carbon has profound influence on our policy process and embodies the very real costs of climate change that communities around the country are already feeling.

The Administration’s distortion of these values is illustrative of a frequent strategy of theirs – twisting the facts to validate their desired outcome, and in the process sowing doubt around the overwhelming scientific consensus on climate change.

Unfortunately, while the math the Administration is using is warped, the costs of climate change are still very real – and the American public is footing the bill.

The Clean Power Plan’s enormous climate benefits – in one graphic

By Ilissa Ocko / Published: October 10, 2017

In addition to the vital public health benefits it offers, the Clean Power Plan is the nation’s most significant action to date to address climate change’s number one culprit – heat-trapping carbon dioxide emissions.

Now, EPA Administrator Scott Pruitt is trying to revoke the Clean Power Plan. Here’s a look at the enormous benefits we could lose.

When the Clean Power Plan is fully in place by 2030, the avoided annual carbon dioxide emissions relative to business-as-usual (350 million metric tons) are equivalent to preventing:

  • 40 billion gallons of gasoline consumed, or
  • 380 billion pounds of coal burned, or
  • 810 million barrels of oil consumed, or
  • 850 billion miles driven by an average car.

In order to get the same climate benefits that the Clean Power Plan would deliver, we would need to:

  • Replace 12 billion incandescent light bulbs with LEDs, or
  • Take 75 million cars off the road

Climate and clean energy progress continues in spite of Clean Power Plan repeal rumors

By Charlie Jiang / Published: October 5, 2017

According to news reports, Environmental Protection Agency (EPA) Administrator Scott Pruitt is planning to start the process of repealing the Clean Power Plan very soon.

This seriously flawed and misguided effort would be a dangerous step backwards for public health and climate protections.

However, as the Trump Administration continues to unravel these protections, the transition to a clean energy future is accelerating. States, cities, and power companies are responding to the ongoing attacks by forging ahead with ambitious actions to slash carbon pollution in order to respond to the threat of climate change and accelerate the clean energy revolution.

Clean Power Plan repeal?

The Clean Power Plan is a common-sense rule to safeguard public health by reducing carbon pollution from power plants to 32 percent below 2005 levels by 2030.

The Clean Power Plan would prevent:

  • 3,600 premature deaths each year
  • 1,700 heart attacks each year
  • 90,000 asthma attacks each year

Administrator Pruitt reportedly intends to propose repealing the Clean Power Plan in the coming days.

If so, EPA will likely issue an “Advance Notice of Proposed Rulemaking” (ANPR) to solicit public input on a replacement rule – a protracted process that is likely to lead to a far weaker standard.

The ANPR process could lead to years of harmful and unjustified delay in implementing urgently needed limits on carbon pollution from fossil fuel power plants.

Forging ahead to a clean energy future

The U.S. power sector has already made enormous strides in deploying clean energy resources and slashing greenhouse gas emissions.

American Wind Energy Association

 

Solar Jobs Census 2016 – The Solar Foundation, interactive map

Globally, the International Energy Agency (IEA) reported yesterday that renewables accounted for almost two-thirds of new capacity installed.

  • Solar additions worldwide grew faster than any other fuel last year, including coal and natural gas.
  • Over the next five years, the IEA projects renewable capacity to grow by over 920 gigawatts – a 43 percent increase by 2022.

Meanwhile, by the end of 2016, carbon pollution from U.S. power plants had already declined to 25 percent below 2005 levels – meaning the power sector is already almost 80 percent of the way to achieving the Clean Power Plan’s 2030 targets.

A new report by the Institute for Policy Integrity highlights the falling costs of complying with the Clean Power Plan. The report points to several market and policy developments including low natural prices, declining renewable energy costs, the 2015 renewable energy tax credit extensions, and state programs supporting the adoption of clean energy technologies.

The Clean Power Plan targets have become a floor for forward-looking states and companies that acknowledge the Clean Power Plan was a first step towards realizing the promise of a low-carbon power sector.

Yet this shift towards clean energy – driven by market forces and accelerating subnational action – is no substitute for decisive federal action that will ensure continued and accelerated progress in achieving the emissions reductions required to stem the tide of climate change.

The U.S. Energy Information Administration projects that without the Clean Power Plan, carbon emissions from the power sector will increase by 2030 – reversing the current downward trajectory in the United States and leaving the country behind as the global clean energy revolution continues.

To keep us moving forward, state and local officials are stepping up their game by cutting carbon pollution and switching to clean energy in spite of — and in direct response to — President Trump’s rollbacks.

  • Fourteen states and Puerto Rico, accounting for more than 10 percent of U.S. carbon emissions from the power sector, pledged as part of the new U.S. Climate Alliance to reduce their greenhouse gas emissions consistent with the goals of the Paris Agreement, as well as meet or exceed their Clean Power Plan targets.
  • 381 mayors (and counting) representing more than 67 million Americans also pledged to honor the Paris Agreement goals and work to meet the 1.5° Celsius global temperature target. Dozens of cities have committed to move to 100 percent clean energy.
  • Colorado Governor John Hickenlooper signed an executive order in July 2017 committing the state to slash greenhouse gas emissions to 26 percent below 2005 levels by 2026, consistent with U.S. goals under the Paris Agreement. “The vast majority of our residents, and indeed the country, expect us to help lead the way toward a clean and affordable energy future,” Governor Hickenlooper said in a press release.
  • Nine states comprising the Regional Greenhouse Gas Initiative (RGGI) in August announced a proposal to cut carbon pollution from the power sector an additional 30 percent between 2020 and 2030 – a 65 percent reduction below the original 2009 pollution cap. The proposal demonstrates bipartisan commitment to combat climate change, with five Republican and four Democratic governors helming the RGGI states (Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New York, Rhode Island, and Vermont). Meanwhile, both New Jersey gubernatorial frontrunners have pledged to rejoin RGGI after this year’s election.
  • Virginia regulators are working to establish a “trading-ready” program to slash power plant carbon emissions in response to an executive order Governor Terry McAuliffe signed in May 2017. “Today, I am proud to take executive action to cut greenhouse gases and make Virginia a leader in the global clean energy economy,” Governor McAuliffe said when he signed the order.
  • California affirmed its position as a global leader on climate progress with a bevy of actions in the past year. In September 2016, legislators passed SB 32, which requires the state to slash greenhouse gas emissions to 40 percent below 1990 levels by 2030. In July 2017, the state secured a 10-year extension to its landmark cap-and-trade program and strengthened tools to improve local air quality in a bipartisan effort. “All over the world, momentum is building to deal seriously with climate change,” Governor Jerry Brown said in July. “Despite rejection in Washington, California is all in.”
  • At least 20 states and the District of Columbia have adopted ambitious greenhouse gas reduction targets, with most aiming for an 80 percent reduction by 2050 below baselines ranging from 1990 to 2006. Twenty-nine states and D.C. have binding renewable portfolio standards in place, while eight more have set renewable portfolio goals. Twenty states have set mandatory energy efficiency targets, while eight more have set energy efficiency goals.

The nation’s largest power companies are similarly pledging to slash carbon pollution and deploy renewable energy resources as they embrace the rapid transition to a clean energy economy.

  • The CEO of American Electric Power (AEP), the country’s largest generator of electricity from coal, had this to say in response to President Trump’s decision to withdraw the U.S. from the Paris Agreement: “I think it’s really important for us to stay engaged from an international community standpoint, particularly addressing large issues. And not withstanding that, we’re continuing on our path of moving to a clean energy economy.” AEP has cut carbon pollution by 44 percent since 2005, and has plans to add more than eight gigawatts of wind and solar in the coming years.
  • Duke Energy, the nation’s largest power producer, this year announced plans to reduce carbon emissions to 40 percent below 2005 levels by 2030. “Our next major investment platform focuses on generating cleaner energy,” said CEO Lynn Good. “Our retirement of more than 40 older, less efficient coal units, coupled with the addition of clean natural gas plants and renewables, is driving our emissions reduction.”
  • DTE Energy Co. announced plans in May 2017 to curb its carbon emissions more than 80 percent by 2050 by closing coal-fired power plants and adding new gas-fired generation and renewables. “Not only is the 80 percent reduction goal achievable – it is achievable in a way that keeps Michigan’s power affordable and reliable,” DTE Chairman and CEO Gerry Anderson said. “There doesn’t have to be a choice between the health of our environment or the health of our economy; we can achieve both.”
  • Xcel Energy committed in June 2017 to achieving a 60 percent reduction in carbon emissions by 2030, relative to 2005 levels. In August, the company announced plans to retire two coal-fired units in Colorado, continuing its progress towards a cleaner generating portfolio. In addition, Xcel’s massive new investments in renewable energy –including a proposal to add 3,380 megawatts of wind generation across seven states –will help the company generate 40 percent of its energy from renewables by 2021.
  • Berkshire Hathaway Energy subsidiary MidAmerican Energy has announced a goal to provide 100 percent renewable energy, including a $3.6 billion project to add 2,000 megawatts of wind, which will expand wind energy to 85 percent of the company’s sales. Said CEO Bill Fehrman: “Our customers want more renewable energy, and we couldn’t agree more.”
  • Minnesota Power, a division of ALLETE, plans to provide 44 percent of its electricity from renewable resources by 2025. Said one executive, “We look forward to working with our customers and regulators to continue down the path toward a safe, reliable, cleaner and affordable energy future.”

The imperative of addressing climate change, overwhelming public support for climate action, and clear market trends towards lower-carbon energy resources are driving states, cities, and power companies to lead the way to a low-carbon future.

If governors, mayors, and power sector CEOs continue to take steps to reduce carbon pollution, they will realize the tremendous benefits of a clean energy economy — thousands of new jobs, critical public health protections, and increasingly resilient communities and infrastructure.

The Trump Administration’s effort to repeal the common-sense Clean Power Plan – its latest attack on life-saving safeguards for our children’s health – will not change the reality of climate change or the accelerating transition to an economy powered by low-carbon energy.

However, without a quick return to meaningful federal progress, the U.S. will fall further behind in the global clean energy revolution – one that could lead to shared prosperity and enormous opportunities for millions of Americans.

Annual festival reinforces strong Latino connection to the environment

By EDF Blogs / Published: October 5, 2017

By Gabriela Zayas del Rio

To kick off National Hispanic Heritage Month, which spans from September 15th to October 15th, Americas Latino Eco Festival convened for its fifth year in Denver, Colorado. The festival, organized by the Americas for Conservation and the Arts in partnership with the U.S. Forest Service, is a weekend-long gathering focused on the many ways in which Latinos and Latin Americans practice and promote environmental awareness.

This year’s festival focused on a call for unity and perseverance among environmental advocates to work together during challenging times. This idea is especially important as a swath of public health safeguards are under attack and as the Environmental Protection Agency faces steep budget cuts.

These actions would put Americans’ health and safety at risk and be felt by all, but Latinos in the U.S. and other minorities will be disproportionately impacted from weak environmental standards and enforcement. Already, nearly one in every two Latinos in the U.S. live in counties that frequently violate the standards for ground-level ozone, also known as smog, and Latino children are 40 percent more likely to die from asthma than non-Latino whites.

The festival’s activities covered a range of topics but a few key themes stood out to me as they reinforced Latinos and Latin Americans’ inherent connection to nature as a source of life, healing, and community:

  1. Sustainability is in our heritage and conservation is our legacy

For centuries, Latino communities have lived in sync with the land to prosper and to preserve resources for future generations. The festival devoted a session to the “acequia,” a system of communal irrigation canals to sustainably manage water distribution across vast, desert-like areas. We can learn immensely from this model of cooperation to more efficiently meet our needs while allowing nature to thrive.

Latinos are also the people who envisioned a zero-waste society long before it became a “modern” solution. Seven centuries ago, the Aztecs saw food waste as a resource that could be used productively in manufacturing and agriculture. They eliminated waste and found creative ways to incentivize recycling and reusing.

This unique take on sustainability is an ethic that continues in our culture today; for instance growing up in my household we reused everything, including repurposing butter containers as tupperware.

  1. Together we are stronger

The Latino community works tirelessly to bring communities together, to educate ourselves, and to demand equal access to a healthy environment. In the process, we try to be inclusive of age, race, gender, sexual orientation, religion, and nationality, demonstrating that we all have an indispensable role to play in environmental conservation.

The festival elevated this principle through an event organized with the Denver Museum of Nature and Science that brought 400 kids from Title 1 schools together to learn actionable ways in which they can be citizen scientists and environmental stewards.

  1. Just transitions must be center stage

The need to acknowledge that environmental progress will not be achieved without equity and without empowering front-line communities was embedded throughout the festival.

Whether transitioning to clean energy, providing disaster relief, or advocating for any environmental policy, all must seek to be done justly, keeping the vulnerable communities in mind.

As a Puerto Rican entering her seventh year in the Diaspora, I was reaffirmed about my role in the environmental movement, especially now as my home and the Caribbean grapple with recovery from Hurricanes Irma and Maria. Hearing from water protectors and commemorating the legacy of activist Berta Cáceres and the likes, all heroes who risked or lost their lives protecting nature, I felt triumphant and convinced that we have the right voices and tools to shatter all misconceptions about Latinos and the environment.

The festival was a testament to the strong commitment of Latinos and Latin Americans to conservation issues. Along with prioritizing a strong economy, we place water conservation and reducing air pollution as the most important issues that should be addressed by our government. We also disproportionately support action to address climate change, see the value in protecting national parks to strengthen the economy, and believe that outdoor activities, such as hiking and fishing, are an integral part of our culture and community.

Our culture and heritage have persevered for centuries, and have left an indelible mark in the environmental movement and this country. Likewise, I fully expect Latinos and Latin Americans will continue to demonstrate their resilience in the face of climate change.

Puerto Rico a tragic reminder of why climate action cannot wait

By Ilissa Ocko / Published: October 3, 2017

Source: FEMA

The disaster unfolding in Puerto Rico is heartbreaking – and a call for action.

Our focus as a nation must be to help our fellow citizens as quickly as possible, but also to do what we can to prevent similar catastrophic events in the future.

With three Category 4 hurricanes – undoubtedly worsened by climate change – making landfall and wreaking havoc in the United States in just a few weeks, we’ve had three wake-up calls. Climate change is an urgent issue that must be addressed now.

By continuing to ignore the fundamental threat that global warming poses today, however, the Trump administration is setting up Puerto Rico and the rest of the Hurricane Alley region for more disasters and tragedies.

It’s akin to a doctor who treats the symptoms of a patient while ignoring a dangerous, underlying disease. It makes for a bad doctor – and America expects more than that.

Puerto Ricans are living climate change

Considered a “canary in the coal mine” for climate change, the Commonwealth of Puerto Rico has been feeling the consequences of a warming world for some time already.

Its beaches are retreating with some homes in the capital of San Juan and in Rincón, a popular surfing town, actually falling into the ocean amid rising seas – and coastal flooding is getting worse.

That’s not all: The island is also challenged by intensifying tropical heat, heavier downpours and – as we just saw with Hurricane Maria – its location in the path of stronger hurricanes.

When rebuilding Puerto Rico, we need to help the island become more resilient to such impacts of climate change – while doubling down on curbing emissions that cause the problem in the first place.

Island’s economy hangs in balance

A vast majority of the Puerto Rico’s population of 3.4 million, more than 85 percent, lives within five miles of a coast that is threatened by the rising ocean.

Like islands in the South Pacific, it’s seeing sea level rise of about half a foot on average from melting land ice and warmer ocean waters. This trend, which is accelerating, has made roads, ports and other infrastructure that are key to Puerto Rico’s economy more vulnerable.

As we’ve seen over the past few weeks, sea level rise compounds the impacts of hurricanes when worsened storm surge causes flooding in communities along the coast. The resulting damage from this and other climate impacts has a direct effect on Puerto Rican daily life as well as on tourism, which accounts for 8 percent of the island’s economy.

Climate impacts are getting worse

Scientists predict Puerto Rico will see a sea level rise of 22 inches by 2060. That translates into a lot more storm surge, more destroyed property and even bigger hits to the nation’s tourist economy.

Research also suggests more heat, rainfall, and stronger hurricanes are in the future [PDF] for Puerto Rico.

The science is clear: Rising temperatures and heavier rainfall both play a key role in intensifying hurricane strength and destruction.

Ninety percent of excess heat is absorbed by the oceans and this warming water energizes hurricanes and evaporates more water into the atmosphere, increasing the amount of rainfall in storms – just like we’ve seen in recent weeks.

All these challenges will escalate in coming decades.

These fellow Americans deserve our help

As we see in Puerto Rico today, it’s the most vulnerable among us who feel the impacts of climate change the most. They need our help to build a better and stronger future.

Treating the symptoms of climate change is absolutely essential. We must come together quickly as a nation and help our fellow Americans through this crisis.

But treating the underlying disease – heat-trapping gas emissions – is equally essential. Or the devastation we’re witnessing in Puerto Rico will keep happening.
