NYT's Tom Friedman: 'UNTIL we fully understand what turned two brothers who allegedly perpetrated the Boston Marathon bombings into murderers, it is hard to make any policy recommendation other than this: We need to redouble our efforts to make America stronger and healthier so it remains a vibrant counterexample to whatever bigoted ideology may have gripped these young men...So what to do?...The best place to start is with a carbon tax'
'Physicist Clive Best has analyzed the latest NASA satellite and radiosonde data to find that global water vapor has declined despite the consensus belief among climate scientists that it would rise in response to man-made carbon dioxide. Dire predictions of global warming all rely on positive feedback from water vapor. The argument goes that as surface temperatures rise so more water will evaporate from the oceans thereby amplifying temperatures because H2O itself is a strong greenhouse gas. The fact that water vapor has instead declined indicates water vapor feedback is negative, overwhelming alleged warming from CO2, and accounting for the stall in global temperatures over the past 16+ years. As Dr. Best notes, "All climate models (that I am aware of) predict exactly the opposite. Something is clearly amiss with theory. Is it not now time for “consensus” scientists to have a rethink?'
'Many scientists say they expect a revival of warming in coming years. Theories for the pause include that deep oceans have taken up more heat with the result that the surface is cooler than expected, that industrial pollution in Asia or clouds are blocking the sun, or that greenhouse gases trap less heat than previously believed. The change may be a result of an observed decline in heat-trapping water vapor in the high atmosphere, for unknown reasons. It could be a combination of factors or some as yet unknown natural variations, scientists say...'The climate system is not quite so simple as people thought,'said Bjorn Lomborg...'My own confidence in the data has gone down in the past five years,' said Richard Tol, an expert in climate change and professor of economics at the University of Sussex in England...Greenhouse gas emissions have hit repeated record highs with annual growth of about 3 percent in most of the decade to 2010, partly powered by rises in China and India. World emissions were 75 percent higher in 2010 than in 1970, UN data show'
'Last year's huge drought was a freak of nature that wasn't caused by man-made global warming, a new federal science study finds. Scientists say the lack of moisture usually pushed up from the Gulf of Mexico was the main reason for the drought in the nation's midsection. Thursday's report by dozens of scientists from five different federal agencies looked into why forecasters didn't see the drought coming. The researchers concluded that it was so unusual and unpredictable that it couldn't have been forecast. "This is one of those events that comes along once every couple hundreds of years," said lead author Martin Hoerling, a research meteorologist at the National Oceanic and Atmospheric Administration. "Climate change was not a significant part, if any, of the event."
Other scientists have linked recent changes in the jet stream to shrinking Arctic sea ice, but Hoerling and study co-author Richard Seager of Columbia University said those global warming connections are not valid.
Hoerling used computer simulations to see if he could replicate the drought using man-made global warming conditions. He couldn't. So that means it was a random event, he said.
"Fat is converted to carbon dioxide and water. You exhale the carbon dioxide and the water mixes into your circulation until it’s lost as urine or sweat." "If you lose 10kg of fat, precisely 8.4kg comes out through your lungs and the remaining 1.6kg turns into water. In other words, nearly all the weight we lose is exhaled."
"To lose 100 grams of fat, you have to exhale 280 grams of carbon dioxide on top of what you’ll produce by vaporizing all your food, no matter what it is."
