Climate 411

Antarctica’s Glacial Melt

By Gernot Wagner / Published: August 10, 2012

There should no longer be any doubt. Climate change is here, and it is happening. 26,000 broken heat records this summer speak for themselves.

Extreme weather events hit home. Another consequence of climate change, by contrast – rising sea levels – often seems far away and far off.

“Far away” is easily dismissed. U.S. coasts are as much in danger as sea shores anywhere else on the planet.

“Far off” often seems tougher to address. After all, seas have only risen by inches so far. Projections say we could see three or more feet by the end of the century.

Even right now, though, we’re seeing the evidence of sea level rise. Antarctic ice sheets have been melting to the tune of 24 cubic miles of melt water per year, every year, since 2002.

That is a huge number, but a fairly abstract number. So The Globalist designed a quiz to make the giant quantity feel a bit more real. EDF was honored to help with the research for the quiz.

See if you can answer the question:

If you were to take the melt-off from Antarctica’s ice sheets over the past decade (2002 to 2012) and pour it into a California-sized Jell-O mold, how high would the water rise?

The right answer might surprise you. Hint: Think Paul Sturgess, the world’s tallest professional basketball player.

And check out The Globalist quiz for more details.

Hot Topic: Climate Change and Our Extreme Weather

By Steven Hamburg / Published: July 13, 2012

Americans have been griping all summer about the weather. It feels hotter than usual this year.

Turns out, that’s because – it is.

The National Oceanic and Atmospheric Administration (NOAA) just confirmed that America is enduring the hottest weather in our recorded history.

In fact, the past 12 months have been the warmest 12 months in the continental U.S. since record-keeping began back in 1895.

It’s not a coincidence either. NOAA says the odds of our record heat being a random event — rather than part of a global warming trend — are about 1 in 1.6 million.

How hot is it, really? Consider these facts from NOAA:

  • From June 1st through July 10th of this year, the U.S. broke 147 all-time high-temperature records.
  • In June of 2012, communities across the U.S. broke 2,284 daily maximum temperature records. In the week of July 1st through July 9th of this year, they broke another 2,071.
  • The average temperature in the contiguous United States was 71.2 degrees Fahrenheit this June – two full degrees above the 20th-century average.

Those scary statistics are just for the past six weeks. But our miserable June followed the blistering heat from last year.

Read all about it in NOAA’s new report, State of the Climate in 2011.)

Take a look at this partial list of cities that broke records from June of 2011 through May of 2012:

  • Detroit – 101 degrees (daily record)
  • Syracuse – 101 degrees (daily record)
  • Mitchell, SD – 102 degrees (daily record)
  • Minneapolis – 103 degrees (daily record)
  • Bridgeport, CT – 103 degrees (all-time record)
  • Denver – 105 degrees (all-time record)      
  • Newark– 108 degrees (all-time record)
  • Houston – 109 degrees (all-time record)
  • Miles City, MT – 111 degrees (all-time record)
  • Wichita – 111 degrees (daily record)
  • Little Rock – 114 degrees (all-time record)
  • Childress, TX – 117 degrees (all-time record)

We’ve included some of those temperatures in our newest EDF public service announcement, which is running on the jumbo screen in Times Square. Just in case you’re not in Times Square right now — see the ad here.

The blazing temperatures have led to other problems as well:

  • The U.S. Drought Monitor says more than 56 percent of the contiguous United States is now under drought conditions — the highest level since record-keeping began in 2000.
  • Wildfires destroyed 1.3 million acres in Colorado and across the U.S. last month.
  • Wyoming recorded its driest June ever this year; Colorado and Utah recorded their second-driest Junes.

At the same time:

  • Florida recorded its wettest June ever — thanks in part to Tropical Storm Debby, which dumped more than two feet of rain on some towns, and spawned flash floods and almost two dozen tornadoes.
  • Duluth, Minnesota also had record floods last month.
  • Large parts of the East Coast got hit by a killer Derecho storm that killed more than two dozen people; more than three million lost electricity, some for more than a week.
  • Washington, D.C. broke its record for worst heat wave ever, according to the Washington Post.

Unfortunately, these bad weather trends are not unexpected. For a long time now, the world’s top climate researchers have told us about the strong evidence of links between dangerous weather and climate change.

Here at EDF, we’ve been talking – and blogging – about the issue for a long time. It was barely more than six months ago that we posted about the IPCC report on climate change and extreme weather. Sadly, looking back at the last round of weather disasters gives our current sweltering summer a sense of déjà vu.

Greenhouse gas pollution traps heat in our atmosphere, which interferes with normal weather patterns. That means we can expect more – and probably worse – weird weather in the future.

Climate change doesn’t just mean higher heat. It means more severe and damaging weather events across the country – including more frequent and heavier rains in some areas, increased drought in others, a potential increase in the intensity of hurricanes, and more coastal erosion because of rising sea levels.

Changing weather patterns changes will affect our agriculture, water supplies, health and economy. They’ll affect every American community and, ultimately, every American.

That’s why EDF is dedicated to reducing carbon pollution.

After all the reports, and all the statistics, and all the bad weather –there’s no excuse for not fighting climate change.

A Great Day for Science Too: More on the Court Decision Affirming Historic Climate Protections

By Steven Hamburg / Published: June 28, 2012

On good days, the facts prevail — and Tuesday was one of those very good days.

As Fred wrote, on Tuesday the U.S. Court of Appeals for Washington, D.C. issued a unanimous, historic decision upholding EPA’s actions to reduce climate pollution.

In our press release, Fred called it a good day for the “thin layer of atmosphere that sustains life on Earth.”

He’s right of course. But our planet wasn’t the only big winner. It was also a great day for science.

The court roundly rejected challenges to EPA’s science-based finding that greenhouse gas emissions endanger public health and welfare (commonly called the Endangerment Finding).

In the process, the court reaffirmed the importance of having rigorous, independent science as the bedrock of efforts to protect our health and environment.

The court’s eloquent statement speaks for itself:    

EPA simply did here what it and other decision-makers often must do to make a science-based judgment:  it sought out and revised existing scientific evidence to determine whether a particular finding was warranted.  It makes no difference that much of the scientific evidence in large part consisted of “syntheses” of individual studies and research.  . . .  This is how science works.  EPA is not required to re-prove the existence of the atom every time it approaches a scientific question.

(That’s from page 27 of the ruling. I added the emphasis.)

The court dismissed the challenges to the Endangerment Finding as without “merit”, noting that EPA relied upon an “ocean of evidence” including 18,000 peer-reviewed studies. (You can find those quotes on pages 26, 34 and 38 of the decision.)  

In dismissing this challenge the court acted in concert with our long history of relying on science-based evidence — not only to shape our health and environmental protections, but as the foundation of American innovation and ingenuity. 

EPA’s Endangerment Finding is based on an extensive review of climate change research, including assessments of climate research prepared by the National Research Council of the National Academy of Sciences, the United States Global Change Research Program, and the Intergovernmental Panel on Climate Change. 

The creation of these assessment reports involved thousands of scientists, reviewing thousands of articles from peer-reviewed research journals.

This massive body of research documents the effects that rising atmospheric concentrations of heat-trapping emissions are having on our climate. It also documents the harm that climate impacts cause to human health and welfare. 

Affirming EPA’s reliance on state-of-the-art climate science, the court discussed the substantial evidence supporting EPA’s Endangerment Finding on page 30 of the decision:

To recap, EPA had before it substantial record evidence that anthropogenic emissions of greenhouse gases “very likely” caused warming of the climate over the last several decades. . .  Relying again upon substantial scientific evidence, EPA determined that anthropogenically induced climate change threatens both public health and public welfare.  It found that extreme weather events, changes in air quality, increases in food- and water-borne pathogens, and increases in temperatures are likely to have adverse health effects … The record also supports EPA’s conclusion that climate change endangers human welfare by creating risk to food production and agriculture, forestry, energy, infrastructure, ecosystems, and wildlife. 

The call from scientists worldwide urging swift action to curb climate-destabilizing emissions has been heard. 

EPA’s efforts to fulfill its statutory responsibility to protect human health and the environment from dangerous pollution have been resoundingly affirmed.   

It is a good day to be a scientist, and an American.

(You can read more about the court cases on our website and in my colleague Megan Ceronsky’s earlier blog on the subject. And stay tuned for more analysis of the historic decisions.)

A Great Day for Clean Air: Court Upholds EPA Actions to Reduce Climate Pollution

By Fred Krupp / Published: June 26, 2012

Today is a great day for climate progress in America.

Today, the United States Court of Appeals for the District of Columbia Circuit issued a unanimous, strong and clear opinion affirming the Environmental Protection Agency’s (EPA) historic measures to reduce harmful climate pollution. 

The court’s opinion held that EPA’s climate protections are firmly rooted in science and the law, and grounded in more than 18,000 peer-reviewed scientific publications.  

The court didn’t mince words. The decision says:

EPA’s interpretation of the governing CAA provisions is unambiguously correct.

Even sharper was this part of the decision, in which the court noted that EPA properly relied on comprehensive scientific assessments by authorities such as the National Academies of Science and the Intergovernmental Panel on Climate Change: 

This is how science works. EPA is not required to re-prove the existence of the atom every time it approaches a scientific question.

(Read more on EDF’s website, in our press release and our highlights page, and in our Texas Clean Air Matters blog)

But even in the wake of a compelling court opinion, some continue to focus on the politics of delay, deny and obstruct.  

Responding to the court’s decision, a representative of the National Association of Manufacturers indicated today that it will continue to invest in lawyers and lobbyists to block clean air progress, telling AP:

[w]e will be considering all of our legal options when it comes to halting these devastating regulations.

Fortunately, there are many more who are investing in America’s future. Business leaders, numerous states, and policy makers are working together to reduce harmful carbon pollution. 

America’s automakers defended EPA’s common sense measures to make our cars more efficient, which will save families’ hard-earned money at the gas pump, help break our addiction to imported oil, and reduce climate pollution.

In filings in federal court, the Alliance of Automobile Manufacturers and the Association of Global Automakers have characterized these important standards as:

valid, mandated by law, and non-controversial.

Similarly, a dozen states – California, Delaware, Illinois, Iowa, Maine, Maryland, New Mexico, New York, Oregon, Rhode Island, Vermont and Washington – have intervened in defense of EPA’s clean car standards. 

And small business voices spoke out today in support of EPA’s clean air measures, saying these measures:

are strongly supported by small business owners because they will boost their bottom lines and help secure our nation’s position in the emerging clean energy economy. 

The court’s decision today reaffirms that a strong, diverse set of voices stand ready to work together, building from the bedrock foundation of this historic decision to reduce climate pollution and build a stronger America.

Our EDF experts are poring through all 82 pages of the decision. Stay tuned for more in-depth analysis about what it means, and where we go next.

But for right now, we should all take a moment to celebrate this great news.

Landmark Environmental Court Battle on Horizon

By Peter Zalzal / Published: February 22, 2012

On February 28th and 29th, the Federal Court of Appeals in Washington, D.C. will hear oral arguments in challenges to the Environmental Protection Agency’s landmark clean air measures to protect American’s health and well-being from the clear and present danger of climate pollution.

In one corner states like Texas and large industrial polluters are challenging EPA’s action.  In the other, EPA’s defenders include a dozen states, business like the U.S. auto makers, and environmental groups like EDF.

There are a group of clean air rules in question:

  • The Climate Pollution Endangerment Finding- On December 15, 2009, EPA determined that six greenhouse gases endanger the public health and welfare of current and future generations. EPA based this finding on more than 100 published scientific studies and peer-reviewed syntheses of climate change research.  The finding follows from the Supreme Court’s landmark 2007 decision in Massachusetts v. EPA, where the Court held that greenhouse gases are air pollutants under the Clean Air Act and instructed EPA to determine — on the basis of science — whether these gases endanger human health and welfare.
  • Clean Car Standards- landmark fuel efficiency and greenhouse gas emissions standards for passenger cars and light trucks.  These standards are supported by U.S. auto makers, the United Auto Workers, and a dozen states – among others – because they will reduce our dependence on foreign oil, reduce harmful greenhouse gas pollution, and save consumers money.
  • Application of Climate Pollution Protections to Largest Emitters – EPA requires new large, industrial emitters (like power plants) deploy the best available cost-effective strategies to reduce harmful climate pollution in a timely fashion- a requirement EPA has phased in, focusing on the largest industrial sources of climate pollution while shielding small sources.

There is much at stake for our nation’s environment and economy, but we’ll be in the courtroom and giving you updates every step of the way.

If you’re looking for more background, EDF has compiled detailed information about the cases. You can read more about the rules and the parties involved, and find the court briefs. You can also read about the EPA’s endangerment findings.

Revenge of the Climate Scientists: 38 Experts Set the WSJ Straight

By Steven Hamburg / Published: February 1, 2012

Two days ago, I wrote about a flawed global warming analysis in the Wall Street Journal.

The paper published an opinion piece, No Need to Panic About Global Warming, written by a small group of scientists and engineers who are global warming skeptics.

Today, the other side was heard from.

The Wall Street Journal published a sharp rebuttal from 38 experts — all of them respected climatologists — who call the authors of the first piece:

[T]he climate-science equivalent of dentists practicing cardiology.

Today’s piece points out that most of the authors of the first analysis have no expertise in climate science, although they are accomplished in their own respective fields.

But, as the large group of climate scientists writes today:                   

The National Academy of Sciences of the U.S. (set up by President Abraham Lincoln to advise on scientific issues), as well as major national academies of science around the world and every other authoritative body of scientists active in climate research have stated that the science is clear: The world is heating up and humans are primarily responsible … Research shows that more than 97% of scientists actively publishing in the field agree that climate change is real and human caused. It would be an act of recklessness for any political leader to disregard the weight of evidence and ignore the enormous risks that climate change clearly poses.

I couldn’t agree more.
