US Climate Bomb is Ticking: What the Gas Industry Doesn't Want You to Know Natural gas wells owned by Cabot Oil and Gas in Dimock, Pa., in December 2009. (Photo: Fred R. Conrad / The New York Times)James Hansen's eye-opening article, "Game Over for the Climate," brought widespread attention to the Alberta Tar Sands in Canada as a source of carbon which, if tapped, would lead to irreversible global warming. There is another climate bomb in the United States, shale gas hydraulic fracking, which emits methane, more dangerous than CO2. While many rhetorically call natural gas a bridge to the clean energy future, new information is showing the opposite; natural gas will hasten climate change, poisons the air, land and water, and carries unacceptable risks to our health. We spoke with experts - Cornell engineering professor Dr. Creating the Fog Around Fracking Extraction of oil and natural gas trapped in shale rock far below the earth's surface is an attempt to collect the last fragments of hydrocarbons for fuels and manufacturing.

New Climate Change Report Warns of Dire Consequences The world is not ready for the impacts of climate change, including more extreme weather and the likelihood that populated parts of the planet could be rendered uninhabitable, says the planet's leading body of climate scientists in a major new UN report. The 772 scientists who wrote and edited the report argue that world leaders have only a few years left to reduce carbon emissions enough to avoid catastrophic warming, which would produce significant sea level rise and large-scale shifts in temperatures that would dramatically disrupt human life and natural ecosystems. "Observed impacts of climate change are widespread and consequential," according to the report, which is from the UN's Intergovernmental Panel on Climate Change (IPCC) and was released Monday morning in Yokohama, Japan. The report uses stronger language around current impacts of climate change than past IPCC releases. "Crossing a Threshold" Beyond that point, "impacts will begin to be unacceptably severe," the authors wrote.
The global energy challenge: Awash with carbon Even though countries are burning unprecedented amounts of oil and gas, the estimates of how much is left continue to grow, thanks to high prices and new technologies that have enabled companies to find and extract new resources. A decade ago, it was the tar sands of Canada and Venezuela. More recently, hydraulic-fracturing technologies have opened up oil and gas resources in the United States. Renewables such as solar and wind power are growing faster than any other source of energy, but are barely making a dent in fossil-fuel consumption.

Nine maps that show how climate change is already affecting the US Climate change isn't just a problem for future generations — it's already affecting broad swaths of the United States. That's the upshot of the National Climate Assessment, a massive new US government report detailing the current and future impacts of global warming around the country. The report is particularly useful in detailing how specific regions and sectors will be affected — and outlining some possible ways we could adapt. There's a lot of information in the report, but here are nine highlights: 1) Every part of the country is getting hotter Temperature changes over the past 22 years (1991-2012) compared to the 1901-1960 average, and compared to the 1951-1980 average for Alaska and Hawai‘i. This map is the simplest way to see global warming in action. Recent decades have been even hotter: since 1991, every region in the United States has been warming, with the biggest temperature increases occurring in the winter and spring. 2) The heaviest storms are getting heavier
Évolution du climat : du passé récent vers le futur - Page 3 Jean JOUZEL, Directeur de Recherches au Laboratoire des Sciences du Climat et de l'Environnement, rapporteur du GIECClaude LORIUS, Directeur de Recherches au Laboratoire de Glaciologie et Géophysique de l'Environnement du CNRS Le climat est un système extrêmement complexe, régi par de multiples interactions entre différents réservoirs (atmosphère, océan, hydrosphère, cryosphère, biosphère...). Un très large spectre d'échelles de temps (de la journée à la centaine de milliers d'années) et d'espace (échelle locale, régionale ou globale) y intervient. Cette complexité explique que l'état de nos connaissances évolue lentement, tout au moins aux yeux du grand public. Cependant, nombreuses sont les avancées et les découvertes qui ont jalonné notre domaine de recherches au cours des dix dernières années.

Business warned to prepare for catastrophic impacts | Guardian Sustainable Business | The Guardian PricewaterhouseCoopers, the world's largest professional services firm, is not known for scaremongering. So it is worth paying particular attention to its latest annual low carbon economy index. Behind the understated language, it points to a catastrophic future unless radical action is taken now to combat climate change. "Business leaders have been asking for clarity in political ambition on climate change," says partner Leo Johnson. The trigger for its dire warning comes from the failure of the global community to reduce carbon emissions by anywhere near the amount needed to restrict temperature rises. PwC's latest report shows the required improvement in global carbon intensity to meet a 2C warming target has risen to 5.1% every year from now to 2050. "We have passed a critical threshold – not once since the second world war has the world achieved that rate of decarbonisation, but the task now confronting us is to achieve it for 39 consecutive years," says the report.
Europe vs CO2 Notre planète est en danger. Les émissions de CO2 n'ont jamais été aussi élevées. Les glaces de l'Arctique sont en train de disparaître . La pollution émise par les véhicules est une cause majeure du changement climatique. Les modèles de voitures que nous conduisons pourraient être beaucoup plus efficaces. Les constructeurs beaucoup plus innovants. Une nouvelle réglementation en Europe permettrait de réduire de moitié les émissions de CO2 des voitures d'ici 2025, et d'envoyer un message au reste du monde, et tout particulièrement aux marchés américains et chinois. Cette soif de pétrole a des conséquences sans précédents sur les régions vulnérables de la planète, comme l'Arctique. La meilleure façon de permettre aux automobilistes de faire des économies de carburant serait d’améliorer l’efficacité énergétique de leurs véhicules. Les automobilistes européens pourraient économiser ainsi 600 euros, soit près d'un quart du budget qu'ils dépensent chaque année.
Taking Climate Change Seriously | Jim Wallis Climate change is about people, not just science and politics -- it is an inter-generational ethics issue. The earth is the Lord's, and in Genesis, God entrusts us with caring for Creation. The earth that we leave to future generations is already being changed by climate change, and so far, our nation has done little to stop climate pollution. The Clean Power Plan, announced Monday by the EPA, is a great step forward for our country in taking climate change seriously. The policy will treat carbon the way it should be treated -- as a pollutant that's harming our health and our planet. The rule reflects some of the best values we hold dear. Congress has been unable to deal with the issue of climate change. And strong social movements need strong and powerful narratives. We should not and cannot leave our children's children with a fundamentally different planet. Climate change is not another issue to move higher up the list of our concerns. "I was hungry." "I was thirsty." "I was naked."
Is Humanity Pushing Earth Past a Tipping Point? | Wired Science Could human activity push Earth’s biological systems to a planet-wide tipping point, causing changes as radical as the Ice Age’s end — but with less pleasant results, and with billions of people along for a bumpy ride? It’s by no means a settled scientific proposition, but many researchers say it’s worth considering — and not just as an apocalyptic warning or far-fetched speculation, but as a legitimate question raised by emerging science. “There are some biological realities we can’t ignore,” said paleoecologist Anthony Barnosky of the University of California, Berkeley. In “Approaching a state shift in Earth’s biosphere,” published June 6 in Nature, Barnosky and 21 co-authors cite 100 papers in summarizing what’s known about environmental tipping points. While the concept was popularized by Malcolm Gladwell’s accounts of sudden, widespread changes in society, the underlying mathematics — which won physicist Kenneth Wilson a Nobel Prize in 1982 — have far-reaching implications.
Obama plan to reduce pollution will allow some states to increase emissions | Environment Barack Obama's new power plant rules will still allow some states to increase their share of the carbon pollution that causes climate change, officials admitted for the first time on Wednesday. Obama and supporters cast the new rules for power plants as an historic step to fighting climate change and protecting public health. But some of the dirtiest and most coal-heavy states – such as West Virginia and Kentucky – will be allowed to maintain or even increase their emissions under the plan, according to analysts. It also hasn't stopped leaders from those same states, West Virginia and Kentucky, from trying to block the rules in Congress or through the courts. The Environmental Protection Agency, which produced the 645-page regulation, said it was possible individual states could increase their emissions while still meeting the overall target of the plan for a 30% cut in national emissions from 2005 levels by 2030. “The bottom line is pretty clear.
How Resource Scarcity and Climate Change Could Produce a Global Explosion (Image: Dark water via Shutterstock)Brace yourself. You may not be able to tell yet, but according to global experts and the U.S. intelligence community, the earth is already shifting under you. Whether you know it or not, you’re on a new planet, a resource-shock world of a sort humanity has never before experienced. Two nightmare scenarios -- a global scarcity of vital resources and the onset of extreme climate change -- are already beginning to converge and in the coming decades are likely to produce a tidal wave of unrest, rebellion, competition, and conflict. Just what this tsunami of disaster will look like may, as yet, be hard to discern, but experts warn of “water wars” over contested river systems, global food riots sparked by soaring prices for life’s basics, mass migrations of climate refugees (with resulting anti-migrant violence), and the breakdown of social order or the collapse of states. Resource Shortages and Resource Wars Water provides another potent example.
Melting Of Antarctic Ice Sheet Might Be Unstoppable hide captionA NASA photo shows the Thwaites Glacier in West Antarctic. A new study indicates that part of the huge West Antarctic Ice Sheet is starting a slow and unstoppable collapse. A NASA photo shows the Thwaites Glacier in West Antarctic. Scientists have long worried about climate change-induced melting of the huge West Antarctic Ice Sheet. That means that in the coming centuries, global sea levels will rise by anywhere from 4 to 12 feet. Ian Joughin, a glaciologist at the University of Washington in Seattle, says people have been speculating that the West Antarctic Ice Sheet is unstable since the 1970s. "It's what's called a marine ice sheet, which means most of it is on the ocean floor instead of on land above sea level," Joughin says. The ice sheet's weak points, such as Thwaites Glacier, have been thinning as warm ocean water eats away at it from underneath, he says. What Rignot and others found is that the threshold for a cascading melt has already been reached.

Climate Change Study Finds U.S. Is Already Widely Affected The effects of human-induced climate change are being felt in every corner of the United States, scientists reported Tuesday, with water growing scarcer in dry regions, torrential rains increasing in wet regions, heat waves becoming more common and more severe, wildfires growing worse, and forests dying under assault from heat-loving insects. Such sweeping changes have been caused by an average warming of less than 2 degrees Fahrenheit over most land areas of the country in the past century, the scientists found. If greenhouse gases like carbon dioxide and methane continue to escalate at a rapid pace, they said, the warming could conceivably exceed 10 degrees by the end of this century. “Climate change, once considered an issue for a distant future, has moved firmly into the present,” the scientists declared in a major new report assessing the situation in the United States. “Yes, climate change is already here,” said Richard B. The ominous findings of the report is likely to give Mr.
