Sea Level. La montée du niveau de la mer 'sous-estimé' L'ampleur de la montée du niveau de la mer résultant du réchauffement des océans a été sous-estimé et représente près de deux fois ce qui avait été calculé jusqu'alors, se sont alarmés lundi des chercheurs allemands dans une publication américaine.

La montée du niveau de la mer 'sous-estimé'

De violentes tempêtes pourraient résulter de ce réchauffement, ont expliqué les scientifiques, dont les conclusions sont publiées dans les Comptes-rendus de l'Académie américaine des sciences (PNAS). Earth ‘covered in plastic’: 5bn tons of waste has contaminated marine life, entered food chain. Some 5 billion tons of plastic waste are littering our planet and the total amount is enough to wrap the Earth in clingfilm, a new international study has found.

Scientists compare the grave pollution levels to a start of a new geological epoch. 2015, la plus chaude des années, et de loin. Scorched Earth Conservation. National park authorities inflict mass destruction on wildlife and habitats, then call it conservation By George Monbiot, published on the Guardian’s website, 14th January 2016 At one end of the country, conservation groups are doing all they can to stop the burning of moors.

Scorched Earth Conservation

Challenging the grouse shooting estates, for example, the RSPB argues that “there is an urgent need to restore these landscapes by … bringing an end to burning.” At the other end of the country, conservation groups are doing everything they can to ensure that moors are burnt. Exmoor and Dartmoor, national parks covered by every possible conservation designation, are now in the middle of swaling season.

Here’s how the Dartmoor authority justifies the practice: Efforts to plug Porter Ranch-area gas leak worsened blowout risk, regulators say. Southern California Gas Co.'s effort to plug its leaking natural gas well involves higher stakes than simply stopping the fumes that have sickened many residents of Porter Ranch.

The company also is trying to avoid a blowout, which state regulators said is now a significant concern after a seventh attempt to plug the well created more precarious conditions at the site. Bernie Sanders’ climate plan would be awesome if he had a friendly Congress, but he won’t. In a move epitomizing his campaign’s often-questionable political strategy, Sen.

Bernie Sanders’ climate plan would be awesome if he had a friendly Congress, but he won’t

Bernie Sanders of Vermont released his climate change plan during the U.N. climate negotiations in Paris. What would normally have drawn immediate attention from climate politics reporters was ignored by the many who were in France covering the most important climate conference in history. To make matters worse, this was shortly before Christmas and New Year’s. Now that the Christmas trees have been dragged to the curb, the mistletoe is being turned to mulch, and the champagne left in the fridge has gone flat, your correspondent has found the time to examine the plan from one of the Senate’s top climate hawks.

Go beyond empirical observation of association between climate and health effect. Improve prediction of associated shifts in infectious diseases at various scales. The health impacts may be controlled through adopting certain proactive measures. Traités de libre-échange : TransCanada réclame 15 milliards de dollars à l'administration américaine pour le rejet de l'oléoduc KeyStone XL. Il y a deux mois, le président Obama avait finalement décidé de rejeter le projet d’oléoduc géant Keystone XL, symbole des projets pétroliers hyper-polluants auxquels il est nécessaire de renoncer pour sauver le climat.

How the huge gas leak is turning California’s Porter Ranch into a ghost town

In the winter of 2008, a real estate column in the Los Angeles Times profiled Porter Ranch, a collection of subdivisions in the San Fernando Valley that feels utterly removed from the huge city on whose northern edge it lies. The neighborhood is “graced with lush parks,” the Neighborly Advice column gushed, and “attracts residents seeking sanctuary from the urban hubbub.” Toll Brothers, the upscale builder that has developed much of the land here, promises potential residents they will “relax in open, natural spaces and live within a true community.” Until very recently, you would have had to do a considerable amount of internet sleuthing to discover that Porter Ranch, home to 30,000 people, is not exactly the pristine, quasi-rural paradise promised by its developers and boosters. Guinea pigs might have a secret defense against climate change. You might picture guinea pigs as sort of the Anne Geddes babies of the animal kingdom — sweet balls of fur perched in miniature tubs, playing with yarn, and frolicking atop piles of flowers.

Guinea pigs might have a secret defense against climate change

But you may not have guessed that these calendar-ready rodents could be resilient badasses when it comes to climate change. No surprise here, but guinea pigs (the epitome of test subjects) recently found themselves at the center of a study about climate change adaption. The results, from New Scientist: “For the first time, wild mammals have been seen responding to higher temperatures by altering chemical structures on their DNA.”

More on the experiment from Nature World News: For the study, male wild guinea pigs were subjected to increasing temperatures at ten degree increments for a period of two months. Climate Change Is Putting Your Favorite Foods at Risk. The climate is changing — the global temperature is rising, weather patterns are changing, sea levels are rising.

Climate Change Is Putting Your Favorite Foods at Risk

Its effects are serious and widespread, but have you ever considered its effects on your favorite foods? Changement climatique: Des rivières d'eau coulent sur le Groenland - Savoir: Sciences. L'étude menée par des chercheurs du Danemark, des Etats-Unis et de l'Université de Zurich sur la calotte glaciaire du Groenland rapporte des découvertes étonnantes, a communiqué l'université de Zurich. Les résultats ont été publiés dans le journal scientifique «Nature Climate Change». Les scientifiques ont analysé le névé, une couche poreuse de neige compactée. Il se forme sous la surface de la calotte glaciaire et, avec le temps, se transforme en glace.

What you should know about California’s massive methane leak. This story was originally published by Mother Jones and is reproduced here as part of the Climate Desk collaboration. For more than two months, California has experienced a slow-moving environmental disaster: Methane leaking from a faulty natural gas well near the Los Angeles neighborhood Porter Ranch has displaced thousands of families and is releasing the greenhouse gas equivalent of driving 7 million cars each day.

Here’s what’s going on: Greenland might be contributing more to sea level rise than we thought. The Greenland ice sheet is starting to look a lot like the ice luge that ruined your New Year’s Eve. What you should know about California’s massive methane leak. GCP : Global Carbon Project : Homepage.
