World renowned scientists agree: humans are changing the climate in detrimental ways

The journal Science has recently published a letter, “Climate Change and the Integrity of Science,” signed by 255 of world’s top scientists which states that:

“There is compelling, comprehensive, and consistent objective evidence that humans are changing the climate in ways that threaten our societies and the ecosystems on which we depend.”

In their letter, the 255 acclaimed scientists boil down their conclusions on climate change into five simple, unequivocal facts:

  • “The planet is warming due to increased concentrations of heat-trapping gases in our atmosphere. A snowy winter in Washington does not alter this fact.
  • Most of the increase in the concentration of these gases over the last century is due to human activities, especially the burning of fossil fuels and deforestation.
  • Natural causes always play a role in changing Earth’s climate, but are now being overwhelmed by human-induced changes.
  • Warming the planet will cause many other climatic patterns to change at speeds unprecedented in modern times, including increasing rates of sea-level rise and alterations in the hydrologic cycle. Rising concentrations of carbon dioxide are making the oceans more acidic.
  • The combination of these complex climate changes threatens coastal communities and cities, our food and water supplies, marine and freshwater ecosystems, forests, high mountain environments, and far more.”

The letter concludes with a strong plea urging policy-makers to “move forward immediately to address the causes of climate change, including the unrestrained burning of fossil fuels.”

These scientists are optimistic that with the right policies, we can avoid the worst effects of a changing climate. “The good news is that smart and effective actions are possible. But delay must not be an option.”

Senators should heed their words and work hard to pass comprehensive climate and energy legislation this year. It won’t be easy, but explaining to their grandchildren that the environment is in shambles because they ignored the science or worse, because they didn’t have the courage to act – now that would be exponentially harder.

Blog highlights from the last few days

Dot Earth focuses on the speech Senator Kerry gave at the Good Jobs, Green Jobs conference, an event highlighting employment opportunities in the nascent green economy. Kerry reminds us that:

We cannot drill and burn our way out of danger. But we can invent and invest our way out of it by fully and passionately supporting a shift to a clean energy economy that will allow America to do what it always does – to lead the way into the future.”

Green Inc. points to a report from the U.S. Department of Commerce Economics and Statistics Administrations showing that green jobs are on the rise.

E2 has Reid hopeful that  “the Gulf of Mexico oil spill should accelerate efforts to move energy legislation that boosts alternative sources.“

Reid explains:

“So I think, rather than slow us up, I think it [the spill] should expedite our doing energy legislation.”

Treehugger brings news of progress being made in the oil spill containment effort. “BP succeeded in plugging one of the three leaks that are spewing vast quantities of oil in the Gulf of Mexico. This was done with the help of underwater remotely operated vehicles; the robots were able to place a special valve on the leaking drill pipe on the sea floor, about 5,000 feet deep.”

Treehugger also applauds Google’s $39 million investment in wind farms in North Dakota.

The Latest on the Oil Spill and Webinar Announcement

E2 gives a round-up of the latest news on the oil spill. Doug Suttles, chief operating officer of exploration and production for London-based BP, describes the current plan for containment.

“The 125-ton, 40-foot-tall steel box designed to capture 85 percent of the oil will be shipped today at noon, and it will take an additional 60 hours to put it on the seafloor, Suttles said. A drill ship would collect the oil from a 5,000-foot riser and separate it from water and gas.”

The Energy Collective is hosting a live webcast featuring Senator Lamar Alexander (R-Tenn.), Fred Krupp, president of the Environmental Defense Fund, and Energy Collective featured bloggers Marc Gunther and Jesse Jenkins. To hear their take on how the Gulf oil spill and other factors are effecting the chances of climate legislation, sign up and tune in Thursday, May 6, 11:30am. You can also submit your own questions live during the event.

Top blog highlights and comments on the oil spill

E2 covers the oil spill and quotes Obama saying that the disaster is

“massive, potentially unprecedented.”

Gernot Wagner, EDF economist notes:

What’s amazing here is to think about the scale. No one knows for sure, but the best estimates talk about 5,000 barrels a day gushing into the Gulf of Mexico. That’s potentially catastrophic and unprecedented on so many levels and could have devastating effects on the fragile ecosystems along the Gulf Coast.

Yet 5,000 is tiny compared to the 1,700,000 barrels produced in the Gulf each day from nearly 3,500 production platforms. That’s a lot more potential disasters waiting to happen. And many are indeed happening. A 2002 Harvard study estimates that around 50,000 to 100,000 barrels of oil are unintentionally released into the environment every day.

That compares to 20,000,000 barrels we consume every single day in the United States alone (a full quarter of what the world consumes overall). We simply cannot drill ourselves out of our oil dependency. It takes a much broader, comprehensive energy strategy that includes both real measures to address environmental disasters like the one unfolding in the Gulf and the one unfolding all around us—global warming pollution caused by burning oil the way it’s supposed to happen, which by itself is far from clean.

Ezra Klein interviews Lisa Margonelli on her New York Times op-ed “Oil On the Brain: Petroleum’s Long Strange Trip to Your Tank.” Ezra points out that

“the possible damage from climate change is far greater than from this spill, but people can’t seem to feel it. And so we might overreact to this spill, but underreact to the problem of oil dependency more generally.”

Treehugger teaches us how RV parks and campgrounds are going green. For example, the

Carlsbad KOA in Carlsbad, New Mexico, [has] a 2.4-kilowatt wind turbine and solar water heating system for its swimming pool.”

Green Inc. highlights the recently released State of the Air report that measures air pollution by city.

“In the United States, an estimated 175 million people, about 58 percent of the population, live in cities with air pollution levels considered unhealthy under the E.P.A.’s air quality standards.”

Comments on ‘American Power Act’ op-ed

In his New York Times op-ed, David Brooks compares the current climate surrounding energy legislation with the struggle to build the transcontinental railroad. He notes that

“energy innovation is the railroad legislation of today. This country is studded with venture capitalists, scientists, corporate executives and environmental activists atremble over the great opportunities they see ahead. The energy revolution is a material project that arouses moral fervor — exactly the sort of enterprise at which Americans excel.”

He goes on to say:

“the best vehicle now is the American Power Act, drawn up by John Kerry, Joe Lieberman and Lindsey Graham.”

We believe, based on what we’ve seen the press, that the American Power Act is not just the best option, but also a great option its own right. It does incorporate its fair share of compromises however it also achieves what no other climate and energy legislation put forth to date has managed to do:  it cuts pollution, spurs clean energy investment and provides a real path to 60 votes in the Senate.

Brooks acknowledges the bill’s imperfections as well as its strengths. He highlights the importance of America’s need to develop clean energy sources at home and asserts that that will only happen once regulations are firmly in place.  He describes the clean energy investment market as a would-be juggernaut currently fettered by Congress.

Hopefully Washington will hear Brooks’s message, stop with the “political gamesmanship” as he calls it, and start taking the first steps towards our clean energy future by passing the American Power Act and putting a price on carbon.

Comments on yesterday’s top blogs

On E2, Nike, eBay and others are asking Senators to “get stalled climate and energy legislation back on track.”

Reuters reports that the U.S. Environmental Protection Agency will start analyzing the comprehensive climate and clean energy bill. “The EPA analysis is an important step in the legislative process.” “We are sending the bill to be modeled now with Lindsey Graham’s consent,” Senator Kerry told reporters.

Green Inc. focuses on a new EPA report released yesterday called “Climate Change Indicators in the United States.”  The report is full of interesting data points and graphics including:

  • “The portion of North America covered by snow has generally decreased since 1972, although there has been much year-to-year variability. Snow covered an average of 3.18 million square miles of North America during the years 2000 to 2008, compared with 3.43 million square miles during the 1970s.”
  • “In the United States, greenhouse gas emissions caused by human activities increased by 14 percent from 1990 to 2008.”

Gernot Wagner, EDF economist notes:

“The EPA report is a terrific reminder of the fact that climate change is not some distant phenomenon our grand kids may or may not experience. We can already see some of the direct effects all around us. It’s also good reminder of the certainties among the sea of uncertainties surrounding climate change. We don’t know all the details, but the general direction has become increasingly clear. And the parts we don’t know are even scarier.”
