Supercomputer-models-show-severe-turbulence-will-increase-with-climate-change. By now most of us know about the major impacts that global climate change will cause like droughts and rising sea levels, but every once in a while we find out about strange consequences we hadn't considered before like crops having lower nutritional value or planes encountering more turbulence.
That's right. Get ready for far bumpier flights in the future. A new study by a team at the University of Reading found that as carbon dioxide levels in the atmosphere increase throughout this century, severe turbulence -- the kind that actually throws unbuckled passengers out of their seats -- will become two to three times more common. Using a supercomputer, Dr. Paul Williams and his colleagues ran models of winter time clear-air turbulence at 39,000 feet when CO2 levels are twice what they are now, a mark we're expected to hit by the end of the century. Driven by heat and high winds, wildfires are 10 times worse this year than average. Wildfire season, or the period between spring and late fall when dry weather, heat, and ignition sources make wildfires more likely, is already off to a devastating start, with fires already burning through a combined 2 million acres across the country — ten times the average for mid-March.
According to data from the National Interagency Fire Center, more acreage has already burned in 2017 than burned during the entire fire season in 1989, 1993, and 1998. Record-high temperatures combined with low humidity and high wind have created the ideal environment for wildfires throughout much of the Great Plains and into the West, destroying homes and property and resulting in several deaths.
Late last week, a blaze near Boulder, Colorado, forced hundreds to evacuate from their homes. The fire, which burned 74 acres, was fully contained as of Monday. But the containment comes at a cost — according to the Denver Post, it cost firefighters $500,000 to fight the fire. How climate change is screwing up your favorite season. It’s officially fall.
If you live in many parts of the United States, that means trees gilded with reds, golds, and ochres; a sneaking chill in the air; and warm, amber days yielding to nippy evenings. Everything smells like potpourri, crunchy leaves, and a tinge of smoke. Enjoy the idyllic autumnal days while they’re still around. Greenland is melting and dumping phosphorous into the Arctic Ocean. Here are a few things that we know about the Greenland Ice Sheet: 1) it’s big — like, almost 2.5 times the size of Texas; 2) it’s beautiful — I mean, just look at it; and 3) it’s melting.
Now, here are a few things that we don’t know about the ice sheet: 1) is it cool if we call it GrIS? From Halliburton to Walmart, these big corporations will make money off of climate change. This story was originally published by Mother Jones and is reproduced here as part of the Climate Desk collaboration.
Climate change will have some pretty terrifying consequences. Experts have predicted everything from deadly heatwaves and devastating floods to falling crop production and even increased political instability and violence. But according to some of the world’s biggest companies, these future disasters could also present lucrative business opportunities. In a remarkable series of documents submitted to a London-based nonprofit called CDP, big-name corporations describe global warming as a chance to sell more weapons systems to the military, more air conditioners to sweltering civilians, and more medications to people afflicted by tropical diseases.
CDP, which stands for “Carbon Disclosure Project,” asks companies all over the world to disclose information about their greenhouse gas emissions and how the changing climate will impact their operations. Le changement climatique ralentit bien la rotation de la Terre. En résolvant un mystère scientifique, des chercheurs américains viennent de montrer que l'augmentation du niveau de la mer du dernier siècle a bien une influence sur la rotation de notre planète : celle-ci tourne de plus en plus doucement.
À terme, le changement climatique va finir par rallonger la durée des jours terrestres. Parfois, une simple erreur de calcul peut faire naître un grand mystère scientifique... C'est en tout cas ce que vient de prouver l'équipe de Jerry Mitrovica de l'université d'Harvard. We just had a record-breaking wildfire season. Is that climate change? When fire came to Chelan, Wash., it arrived with all the chaos and drama of a fictional apocalypse.
Crowds of tourists gathered to watch a jagged orange line of flame crawl up Chelan Butte, a giant brown hillock that pinches this small city against a namesake lake that punches 50 miles into the steep, glaciated Cascades. Then the crowd ran screaming when 40-mph winds reversed and drove the fire line toward the homes and restaurants that edge the lake. Climate change is making wildfires worse and wildfires are making climate change worse.
It’s the season when wildfires rage, and this year they’re raging particularly hard: In June alone, Alaska saw 1.1 million acres go up in flames.
In California, firefighters had responded to 3,381 wildfires by July 11, “1,000 more than the average over the previous five years,” The New York Times reports in a big feature on wildfires in the state. And that’s likely not a coincidence. A study published this week in Nature Communications connects worsening wildfire seasons to climate change, and suggests the trend will continue in the years ahead as climate change rolls forward.
“Wildfires occur at the intersection of dry weather, available fuel and ignition sources,” the study’s authors write. Of those factors, “weather is the most variable.” Right Relevance: Search or Login for deep topical relevance. 2014 détient le record de l’année la plus chaude jamais enregistrée sur Terre.

New York is among the coastal cities around the world that face a threat from… (Mark Lennihan / Associated…) Climate change will disrupt not only the natural world but also society, posing risks to the world's economy and the food and water supply and contributing to violent conflict, an international panel of scientists says.
The warnings came in a report drafted by the United Nations-backed Intergovernmental Panel on Climate Change. The 29-page summary, leaked and posted on a blog critical of the panel, has been distributed to governments around the world for review. Assessing the impact of climate change on a global scale. Thirty research teams in 12 different countries have systematically compared state-of-the-art computer simulations of climate change impact to assess how climate change might influence global drought, water scarcity and river flooding in the future. What they found was: The frequency of drought may increase by more than 20 per cent in some regions.Without a reduction in global greenhouse-gas emissions, 40 per cent more people are likely to be at risk of absolute water scarcity.Increases in river flooding are expected in more than half of the areas investigated.Adverse climate change impacts can combine to create global 'hotspots' of climate change impacts.
Dr Simon Gosling from the School of Geography at The University of Nottingham co-authored four papers in this unique global collaboration. The results are published this week—Monday 16 December 2013—in a special feature of the Proceedings of the National Academy of Sciences (PNAS). Quels sont les pays les plus vulnérables au changement climatique ?

John Kerry says climate change is a weapon of mass destruction. During his time as president, George W. Bush’s foreign policy was driven largely by fear of terrorists and WMDs. Alaska Hunts Oil as Arctic Damage Shows Most Change From Climate.
When Jerry Otto started hunting for Alaskan oil in 1980, his tractor-trailers barreled along ice roads as much as 10 feet thick for 180 days every year. Last winter, when he set out to drill 80 miles south of the Arctic Ocean for Australia’s Linc Energy Ltd. (LNC), regulators opened the roads for 126 days. The rest of the time, warm weather left the routes too mushy for vehicles, Bloomberg Markets magazine will report in its November issue. More from the November issue of Bloomberg Markets: Why the Arctic is drunk right now. Perhaps the best analogy yet for the insane cold weather now afflicting the U.S. came from science blogger Greg Laden, who created the viral image above. “Go home, Arctic,” it reads.
Climate change study finds Australia suffers more than most G20 countries. Australia's exposure to climate change has worsened more rapidly than in any other major economy in the past two years, with stresses on water supplies increasing and the cost of natural disasters running second only to China, a report has found. The study, compiled by HSBC, found that temperatures in Australia had risen faster than in any other G20 country over the past two years – up by 0.39C to 18.9C on a decade average basis. Deterioration in water resources is also a major issue, with Australia, along with Saudi Arabia, experiencing the worst increases. HSBC concluded that India, China, Indonesia, South Africa and Brazil are the countries most vulnerable to climate change, based on the challenges posed by climate change and their ability to respond to them. Vanishing ocean smell could also mean fewer clouds.
Next time you’re at the beach take a deep, long sniff: That special coastal scent might not last forever. While you’re at it, put on some extra sunscreen: As that smell dwindles, cloud cover could, too. The unique oceanside smell that flows over your olfactory organs is loaded with sulfur — dimethylsulfide, to be exact, or DMS. It’s produced when phytoplankton decompose. And it’s a fragrant compound that’s as special as it smells: In the atmosphere it reacts to produce sulfuric acid, which aids in the formation of clouds. But it’s a smell that’s endangered by climate change. Clouds do more for us than just dispense quenching rain and snow: They also reflect light and heat away from the earth, helping to keep temperatures down. China’s voyage to cross the less frozen Arctic Ocean. For a ship on a mission of worldwide importance, the Yong Sheng is a distinctly unimpressive sight. The grey and green hull of the 19,000-tonne cargo vessel, operated by China‘s state-owned Cosco Group, is streaked with rust, while its cargo of steel and heavy equipment would best be described as prosaic.
