What We Don’t Know Can Hurt Us. Quantifying the Economic Risks of Climate Science Uncertainty SOURCE: Sandia National LaboratoriesA map developed by Sandia Labs shows the GDP risk due to climate uncertainty in 48 US states between 2010 and 2050, in billions of dollars at a 0% discount rate.
What we don’t know about climate science can really hurt us. So says a recent study conducted by researchers at Sandia National Laboratories. One common argument used by those opposed to action on climate change is that there is simply too much uncertainty about the science to warrant any action. Even those policymakers supportive of efforts to address climate change feel hampered by an inability to make its risks palpably relevant to their constituents. In response to discussions with DOE Secretary Chu, Congressmen Jeff Bingaman, Tom Udall, and Mark Heinrich during a visit to Sandia National Laboratories, our team worked to establish the near-term risk from climate change at the level of U.S. states for voters and businesses.
Flood Maps. Why Surfing A Tsunami Wave Won't Work. When the news broke that a tsunami was headed for Hawaii and California, I feared someone would be crazy enough to paddle out ahead of the massive wave and try to ride it.
I was right. Turns out the physics of riding such a wave make it impossible even for a professional surfer. According to the University of Hawaii at Hilo, there are several reasons why it won't work: 1 – Tsunami waves are thicker than normal waves. A tsunami wave is huge — hundreds of miles long — and full of energy. 2- You can't surf in tsunami whitewater. Earth Impact Effects Program. Robert Marcus, H.
Jay Melosh, and Gareth Collins Welcome to the Earth Impact Effects Program: an easy-to-use, interactive web site for estimating the regional environmental consequences of an impact on Earth. This program will estimate the ejecta distribution, ground shaking, atmospheric blast wave, and thermal effects of an impact as well as the size of the crater produced. Please enter values in the boxes below to describe your impact event of choice and your distance away. Then click "Calculate Effects" to learn about the environmental consequences. Tell me more...

WWF - WWF's International Smart Gear Competition. Enter the 2014 International Smart Gear Competition h Improving fishing gear is a key step in reducing bycatch.
Gear modifications can increase the chances of escape for non-target species or, better yet, reduce the number caught in the first place. Simple, inexpensive innovations have proven effective in many fisheries and some of the best solutions to date have come from fishers themselves. WWF, in partnership with industry leaders, scientists and fishers, launched the International Smart Gear Competition in 2004. Designed to inspire creative thinkers, Smart Gear is a call for innovative ideas that have practical applications for fishing “smarter”—for increasing selectivity for target fish species and reducing bycatch.
