Global Warming's Terrifying New Math | Politics News If the pictures of those towering wildfires in Colorado haven't convinced you, or the size of your AC bill this summer, here are some hard numbers about climate change: June broke or tied 3,215 high-temperature records across the United States. That followed the warmest May on record for the Northern Hemisphere – the 327th consecutive month in which the temperature of the entire globe exceeded the 20th-century average, the odds of which occurring by simple chance were 3.7 x 10-99, a number considerably larger than the number of stars in the universe. Meteorologists reported that this spring was the warmest ever recorded for our nation – in fact, it crushed the old record by so much that it represented the "largest temperature departure from average of any season on record." The same week, Saudi authorities reported that it had rained in Mecca despite a temperature of 109 degrees, the hottest downpour in the planet's history. Not that our leaders seemed to notice.

Potsdam Institute for Climate Impact Research — PIK Research Portal Heartland Institute The Heartland Institute, according to the Institute's web site, is a nonprofit "think tank" that questions the reality and import of climate change, second-hand smoke health hazards, and a host of other issues that might seem to require government regulation. A July 2011 Nature editorial points out the group's lack of credibility: "Despite criticizing climate scientists for being overconfident about their data, models and theories, the Heartland Institute proclaims a conspicuous confidence in single studies and grand interpretations....makes many bold assertions that are often questionable or misleading.... Many climate sceptics seem to review scientific data and studies not as scientists but as attorneys, magnifying doubts and treating incomplete explanations as falsehoods rather than signs of progress towards the truth. ... The Heartland Institute and its ilk are not trying to build a theory of anything. They have set the bar much lower, and are happy muddying the waters About Founding

The New Abolitionism Averting planetary disaster will mean forcing fossil fuel companies to give up at least $10 trillion in wealth. Before the cannons fired at Fort Sumter, the Confederates announced their rebellion with lofty rhetoric about “violations of the Constitution of the United States” and “encroachments upon the reserved rights of the States.” But the brute, bloody fact beneath those words was money. So much goddamn money. The leaders of slave power were fighting a movement of dispossession. Today, we rightly recoil at the thought of tabulating slaves as property. In order to get a true sense of how much wealth the South held in bondage, it makes far more sense to look at slavery in terms of the percentage of total economic value it represented at the time. Ten trillion dollars is already a number much too large to comprehend, but remember that wealth was intensely geographically focused. The piece walks through a fairly straightforward bit of arithmetic that goes as follows.

IIASA - International Institute for Applied Systems Analysis Evidence is there, so what are we waiting for? Climate change's link to disasters Not all extreme weather events can be attributed to climate change, but many now can, and researchers say the risk of some disasters is growing. So what now? In their more reflective moments, mainstream climate scientists will tell you they wish they were wrong and that the Andrew Bolts of the world were right. After all, who would want to be right about the planet facing an enormous, transformative threat at the hands of its most powerful custodians? Advertisement Those working on climate science, of course, do not believe they have erred. Yes, warming has slowed in the past 15 years to rates below the long-term average. But nor has it become any cooler - each of the past three decades were warmer than any preceding decade since records began. This is a cautious, and largely technical report. But self-interest will only go so far. Otherwise we chose to engage in an act of self-harm.

Hog Wild: Factory Farms are Poisoning Iowa's Drinking Water Hog Wild: Factory Farms are Poisoning Iowa's Drinking Water Millions of pigs are crammed into overcrowded barns all across the state, being fattened for slaughter while breeding superbugs—all to feed China's growing appetite for Spam. Before I even stepped from my truck onto the gravel outside the New Fashion Pork hog confinement facility, Emily Erickson, the company’s animal well-being and quality assurance manager, handed me a pair of stretchy white plastic footies to put over my shoes. It was a blustery day in September, the sky threatening snow—the first hint of winter, when cold, dry air stabilizes viruses and biosecurity becomes a topmost concern. All of the hogs inside the confinement near Jackson, Minnesota, just north of the Iowa state line and on the headwaters of the Des Moines River, would be sold to Hormel Foods. “It’s a lot of pig, it’s a lot of metal, it’s a lot of noise.” Erickson was right: it is a lot of pig. But then came a revolution in the corn industry.

kelvy bird | surfacing latent, intuited, potential IPCC report finds temperatures on track to rise by more than two degrees Stronger evidence climate change man-made Scientists say it's clear human activities are to blame for the earth's warming in the latest report from the Intergovernmental Panel on Climate Change. 26, 2013 It is more certain than ever that human civilisation is the main cause of global warming, putting the world on track for dangerous temperature rises, the latest major UN assessment of climate change science has found. The Intergovernmental Panel on Climate Change says it is "extremely likely" that humans are the dominant cause of observed warming since the mid-20th century, with carbon dioxide emissions the main factor. If emissions remain high, by 2100 temperatures are likely to rise by more than 2 degrees - and up to 4.8 degrees - breaching a threshold agreed by governments as limiting the worst impacts of climate change.
