Webinar: Climate Stabilization Targets: Emissions, Concentrations, and Impacts Over Decades to Millennia

with one comment

The Union of Concerned Scientists is excited to announce a webinar briefing on the National Research Council’s report, Climate Stabilization Targets: Emissions, Concentrations, and Impacts Over Decades to Millennia. Authors of the report will present key findings and then answer your questions.

More from Climate Stabilization Targets:

Emissions of carbon dioxide from the burning of fossil fuels have ushered in a new epoch where human activities will largely determine the evolution of Earth’s climate. Because carbon dioxide in the atmosphere is long lived, it can effectively lock the Earth and future generations into a range of impacts, some of which could become very severe. Therefore, emissions reductions choices made today matter in determining impacts experienced not just over the next few decades, but in the coming centuries and millennia. Policy choices can be informed by recent advances in climate science that quantify the relationships between increases in carbon dioxide and global warming, related climate changes, and resulting impacts.”

Join the esteemed authors of the report for a 40-minute webinar briefing, followed by a question-and-answer session. The webinar will be held on Friday, May 6, from 1:00-2:00 p.m. (EDT), 10:00-11:00 a.m. (PDT).
Presenters: Dr. Katharine Hayhoe, Texas Tech University; Dr. Damon Matthews, Concordia University, Montreal; and Dr. Gary Yohe, Wesleyan University.

New Web Site: www.shapingtomorrowsworld.org

with one comment

From climate change to peak oil and food security, our societies are confronted with many serious challenges that, if left unresolved, will threaten the well-being of present and future generations, and the natural world. A new website www.shapingtomorrowsworld.org is dedicated to discussion of those challenges and potential solutions based on scientific evidence and scholarly analysis.

Congressman Rohrabacher’s Paper Tiger

with 7 comments

Fact: We are overloading the air and oceans with carbon which is causing too much heat to be trapped.  Climate change is arguably the most studied scientific issue of the day and virtually every scientist and scientific body agrees that the planet is warming, and the primary cause is the massive emission of the heat-trapping gas carbon dioxide.  This overwhelming consensus is driven by the multiple human fingerprints of human-caused warming.  In fact, the United States National Academy of Sciences (NAS) recently issued four reports called America’s Climate Choices (2010) that clearly show humans are driving global warming and the impacts already occurring are cause for serious concern.  The NAS concludes:

”A strong, credible body of scientific evidence shows that climate change is occurring, is caused largely by human activities, and poses significant risks for a broad range of human and natural systems…. Some scientific conclusions or theories have been so thoroughly examined and tested, and supported by so many independent observations and results, that their likelihood of subsequently being found to be wrong is vanishingly small. Such conclusions and theories are then regarded as settled facts. This is the case for the conclusions that the Earth system is warming and that much of this warming is very likely due to human activities.”

Enter Dana Rohrabacher (R-CA) who has a history of getting the science wrongOn three occasions (Feb 4, 2010, March 10, 2010, and Feb 17, 2011), Rep. Rohrabacher has entered  into the Congressional record an open letter signed by over 100 scientists and published as a full page ad in the New York Times, Washington Post, Chicago Tribune, Washington Times, and Los Angeles Times.  The letter was addressed to the President of the United States and flies in the face of the scientific understanding of climate change. The letter can be viewed here

The letter contained 115 signatures and made the following assertions:

  1. The case for alarm regarding climate change is grossly overstated
  2. Characterization of the scientific facts regarding climate change and the degree of certainty informing the scientific debate is simply incorrect
  3. Surface temperature changes over the past century have been episodic and modest
  4. There has been no net global warming for over a decade
  5. The computer models forecasting rapid temperature change abjectly fail to explain recent climate behavior

So who were these scientists and are they qualified to sign this letter?  (Item #4 is an automatic disqualifier in my book because any legitimate expert should know that a decade cannot be used to refute the underlying climate trend.  This claim is especially absurd given that the past three decades have been the warmest in the instrumental record!)

Congress on wrong side of history in denying climate change

with 7 comments

Reposted from The Hill and written by Rep. Betty McCollum (D-Minn.) and John Abraham:

Right now in our hometown of St. Paul, Minnesota, we are preparing for what might possibly be record-breaking floods due to winter’s heavy snowfall and the threat of heavier spring downpours. Minnesota has already experienced two 100-year floods in the Red River Valley within the past 13 years. Local doctors report an increase in cases of children with asthma and other respiratory conditions. Lake Superior has seen record low water levels in recent years, threatening not only drinking water supplies but the Duluth-Superior port that receives more than 1,200 ships and 48 million tons of cargo.

All of these public health, economic, and environmental trends have been strongly linked to climate change. Multiple studies have shown that 97 percent of the most qualified climate scientists are in agreement that humans are causing the planet to warm. If this was an illness, and 97 percent of doctors recommended a certain treatment, we would take appropriate action.

Instead, the majority party in the House of Representatives is choosing to willfully defy the diagnosis and overturn established science by voting on a bill (H.R. 910) that will gut the Clean Air Act and prohibit the Environmental Protection Agency (EPA) from ever protecting the American people from the disastrous impacts of climate change.

Tell White House: EPA Authority Over CO2 Must Not Be Compromised

leave a comment »

Sadly, this isn’t an April Fool’s joke…  Attacks on the Environmental Protection Agency’s (EPA’s) authority to regulate global warming emissions under the Clean Air Act are ongoing. There is some unnerving news from the White House on this front. While these attacks so far have mostly been in the House of Representatives, now the Senate is considering a series of amendments to block EPA action and there are reports that the White House is considering a budget compromise that would block EPA action.
