WWF Climate Blog Has Moved to New Location

The WWF climate blog now is located at a different Web address: worldwildlife.org/blogs/wwf-climate-blog.  All posts since May 2013 are at that location, while older posts will remain archived on this site.  The new site will have a single RSS feed at worldwildlife.org/blogs/wwf-climate-blog.rss.

Our Collision Course with Climate Change: a "10" on the Torino scale

Today (31 May 2013), Asteroid 1998 QE2 will come within 3.6  million miles of the earth, making it a “0” (No Hazard) on the Torino Impact Hazard Scale.  And what is a 10 on the Torino scale?  That would be a situation where "a collision is certain, capable of causing global climatic catastrophe that may threaten the future of civilization as we know it, whether impacting land or ocean. Such events occur on average once per 100,000 years, or less often."  It sounds like the hazard we're facing after pushing atmospheric carbon dioxide concentrations beyond 400 parts per million (ppm). But there are at least three important differences. 

Event on 6 June 2013: "Going to Extremes: The Alarming Science Behind Climate Change’s Increasingly Wild Weather"

Join us for a joint Climate Desk Live and World Wildlife Fund (WWF) event moderated by Chris Mooney featuring Stu Ostro, Senior Director of Weather Communications at the Weather Channel; and Jennifer Francis, Research Professor, Institute of Marine and Coastal Sciences at Rutgers University.

Video: Extreme weather patterns and the possible role of climate change

Face the Nation (CBS) today (26 May 2013) features WFOR's Chief Meteorologist David Bernard, Climate Central's Chief Climatologist Heidi Cullen, TIME Magazine's Jeffrey Kluger and American Meteorological Society President Marshall Shepherd discussing recent extreme weather events, the upcoming hurricane season (starting 1 June), and the role of climate change in recent climate extremes.

Iconic Image: Longest-Running Measurement of Atmospheric CO2 Rises to Highest Daily Value on Record on 16 May 2013

Over the last week, both the National Oceanic and Atmospheric Administration and the Scripps Institution of Oceanography (University of California, San Diego) reported that the daily average concentration of carbon dioxide measured from Mauna Loa, Hawaii surpassed the historic milestone of 400.00 parts per million. Today Scripps reports that on Thursday (16 May), concentrations rose even higher.  The screenshot of the Scripps "Keeling Curve" Web site showing "400.27 ppm" and the curve of rapidly rising concentrations since 1958 merits to be among the iconic images of this era of climate disruption.

2012: The Year Climate Change Got Real for Americans (Video)

In the latest in his “Climate Denial Crock of the Week" video series, Peter Sinclair provides an overview of the climate extremes in 2012 that battered the U.S.  The conditions have helped shift public opinion and elevate the public debate around climate change. 

Talkin' on Turkey Day: A Thanksgiving Climate Pledge

We think of Thanksgiving as an eating holiday, but it really is a "talking holiday" when we slow down and spend the day in conversation.  When the conversation turns to the weather, consider talking about our changing weather patterns and the consequences we are feeling and hearing about.   What if we then spent a little time speaking with each other about steps we can take to prepare for those impacts, and to avoid more serious climate disruption in the future?   If we can pledge to talk turkey with friends and family around the table, we are one step closer to a national conversation about climate change -- and to enduring solutions.

WWF’s Science for Nature Seminar with Katharine Hayhoe: The Facts are Not Enough –Overcoming Public Deadlock on Climate Change

Event Date: 
Thursday, December 13, 2012 (All day)
Event Location: 
WWF, 1250 24th St NW, Washington, D.C

Mounting scientific evidence documents the emerging consequences and future risks of climate change for the United States. As the scientific evidence builds, however, public opinion in the U.S. remains sharply divided. Much of the disagreement comes from political and religious conservatives. Why is climate change so polarizing to these communities? What makes it so hard to comprehend and accept? Join  Dr. Katharine Hayhoe, Director of the Climate Science Center and Associate Professor at Texas Tech University in a seminar where she will identify common barriers to accepting the reality of climate change and explore ways to move past these obstacles towards action.

Great Lakes Climate Symposium 2012

Event Date: 
Tuesday, October 30, 2012 (All day)
Event Location: 
Ann Arbor, MI

Learn about the latest research on climate change in the Great Lakes region from a team of researchers that contributed a set of white papers on Midwest climate impacts to the Federal government's National Climate Assessment.

Science Museum's Climate Change Photo Challenge

Do you have a good photo illustrating some action your community is taking to prepare for changing weather patterns, rising sea levels or other emerging impacts of climate change?  How about a photo showing ways in which your community is helping to reduce its carbon footprint?  If so, consider submitting it (by August 15, by 2 p.m. EDT!) to the Climate Change Photo Challenge of the Koshland Science Museum of the National Academy of Sciences.
