  • "Civilization is on a path to heat the Earth up by 4 to 7 degrees Celsius before the middle of this century if it fails to end its carbon emissions, triggering a cascade of cataclysmic changes that will include the increase of extreme heat-waves, prolonged droughts, intensified weather patterns, the total loss of Arctic sea ice, rapid decline in global food availability, sea level rise affecting billions of people, and eventually an abrupt extinction of the majority of biological life on earth. The solution, while not a simple one to execute, is clear:  Civilization must end its reliance on fossil fuels and begin to sequester CO2 from the atmosphere immediately, reducing the atmospheric concentration of CO2 down to a safe level."

  • When permafrost ['frozen dirt'] thaws, so do the microorganisms. With no oxygen, the microorganisms make methane, and with it they make carbon dioxide, Kevin Schaefer of the U.S. National Snow and Ice Data Centre explains. The concern is that much of the carbon stored in permafrost -- in frozen dirt -- could be released into the carbon cycle, says scientist Charles Miller of NASA/Jet Propulsion Laboratory. The Arctic, Miller says, is being affected by warming faster and more significantly than models had predicted. Methane concentrations, and even CO2 concentrations, "that one might associate with flying near a large oil or natural gas production facility or even flying through the middle of a large city" can be observed from an airplane, he says.

  • Following an overview of the environmental impacts of meat production, this report turns to an outline of the research addressing changing to meat free diets and by doing so I review research into both the barriers and incentives to adopting a meat free diet. I then turn to a more sociological consideration of meat-eating and discuss the cultural and social practices which surround our food choices and beliefs about the necessity of meat in our diets.

  • " Only one conclusion can be drawn as the Arctic ecosystem is being rapidly transformed into a landscape that would not have been recognisable a decade or two ago. At just 0.8ºC of global warming, it is already too hot, and climate change has already gone too far if you value a safe climate in which biodiversity and all the world’s marvellous ecosystems are maintained."

  • "Once the world's ice caps have completely melted away at temperatures above 22.49 oC and times later than 2051.3, the Earth's atmosphere will heat up at an extremely fast rate to reach the Permian extinction event temperature of 80oF (26.66 oC)(Wignall, 2009) by which time all life on Earth will have been completely extinguished." ...

  • "Knowing nothing about de Tocqueville, the ten-year-old son of a friend put his own spin on recent history: “Mom, I think people value Father Time more than they value Mother Earth.” His words sting me like freezing rain, squeezing tears from the corners of my eyes. There’s nothing new there for me, except the perspective of youth: I often weep when I think about the hellishly overheated world we’re leaving him and his young friends. We’re destroying this world in large part because we care more about chasing fiat currency than we care about the living planet and its occupants."

  • "Kevin Anderson is deputy director of the Tyndall Centre for Climate Change Research (UK). In this 57-minute talk (given in July, 2011) he tells us straight from the shoulder the truth about global warming and what's in store for us in the next 20 years as we head for a world that averages 4 degrees Celsius [7 degrees Fahrenheit] warmer than the pre-industrial world -- averaging even warmer on land and far warmer at the poles. As Anderson says, if we know the truth about this, then maybe -- just maybe -- we can do something about it. If we don't know the truth, then we can do nothing."

  • A new study examining nearly 40 years of satellite imagery has revealed that the floating ice shelves of a critical portion of West Antarctica are steadily losing their grip on adjacent bay walls, potentially amplifying an already accelerating loss of ice to the sea.

  • "Humanity is on the brink of an unimaginable catastrophe: the world is marching inexorably toward the most devastating ecocide; global warming and its frightening consequences are announcing it, but their perspective on the ecosystem, which resembles the ideology of the conquistadors Cortés and Pizarro, as the influential French thinker Edgar Morin rightly pointed out, pushes them to continue degrading and destroying. The energy and food crises are sharpening, but capitalism continues to trespass all the limits with impunity."
