Carbon Connections Offshore Wind Farms Guard Landscape Against Hurricanes | I Fucking Love Science - Iceweasel The construction of wind farms in coastal waters could have a benefit besides clean energy. Turbines take energy out of the wind, and modeling shows this could be a significant enough effect to reduce the damage from major storms. Professor Mark Jacobson of Stanford University has spent 24 years modeling atmospheric behavior, including air pollution and climate. "We found that when wind turbines are present, they slow down the outer rotation winds of a hurricane," Jacobson said. Jacobson's model used enormous numbers of turbines. For so many turbines the effect is large. The reductions Jacobson found for Hurricane Sandy were smaller, but still enough to slash the cost in lives and property damage. Proposals to protect against hurricanes usually involve the construction of seawalls. Excessive winds can damage turbines, but Jacobson points out there is safety in numbers – if windfarms are big enough the storms will never become sufficiently powerful to destroy them.

Global Warming Explained, In About A Minute : 13.7: Cosmos And Culture Jean-Pierre Clatot/AFP/Getty Images On a pleasant day in 2011, researchers roamed San Diego's public parks in search of volunteers to fill out anonymous surveys about global warming. In the end about 270 responses were collected from a mix of park visitors and nearby community college students. The researchers wanted to know how well the average American understands the basic processes responsible for global warming, and whether there's a relationship between this basic understanding and the belief that global warming is actually occurring. The results were sobering. While a majority of volunteers believed that global warming is a reality (80 percent) and that human activities are a significant contributing factor (77 percent), only a slim minority was able to explain even rudimentary aspects of the mechanism. Michael Ranney, the lead author on the study, offers this 35-word explanation: Ranney's findings have already proven both surprising and far-reaching.
Giant Crocheted Doily Rug Pattern, At Long Last! - creative jewish mom - Iceweasel At long last, namely almost a year and a half later, I have gotten around to figuring out the pattern for this sweet crocheted doily rug! My apologies to those of you who have been waiting, I quite simply could not find the large chunk of time or the brain power to do this until now! Plus I am not a professional crochet designer or pattern writer by any means, and I knew that there was an inconsistency or two in the pattern, that I had hoped to solve. Now after having made a smaller version of this rug to check the pattern, it turns out that there is one small inconsistency, that I didn't have time to work out, so please do be aware of that, though I state the problem clearly, and it's not something that is noticeable in the outcome of the rug. If any one feels like tackling this problem in the pattern, by all means, give it a try, one just needs to re-work a row or two I believe.
