Three simple numbers that add up to global catastrophe - and that make clear who the real enemy is.
By Bill McKibben
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. Last month the world's nations, meeting in Rio for the 20th-anniversary reprise of a massive 1992 environmental summit, accomplished nothing. Unlike George H.W. Bush, who flew in for the first conclave, Barack Obama didn't even attend. It was "a ghost of the glad, confident meeting 20 years ago," the British journalist George Monbiot wrote; no one paid it much attention, footsteps echoing through the halls "once thronged by multitudes." Since I wrote one of the first books for a general audience about global warming way back in 1989, and since I've spent the intervening decades working ineffectively to slow that warming, I can say with some confidence that we're losing the fight, badly and quickly – losing it because, most of all, we remain in denial about the peril that human civilization is in.
When we think about global warming at all, the arguments tend to be ideological, theological and economic. But to grasp the seriousness of our predicament, you just need to do a little math. For the past year, an easy and powerful bit of arithmetical analysis first published by financial analysts in the U.K. has been making the rounds of environmental conferences and journals, but it hasn't yet broken through to the larger public. This analysis upends most of the conventional political thinking about climate change. And it allows us to understand our precarious – our almost-but-not-quite-finally hopeless – position with three simple numbers.

The U.S. Court of Appeals for the District of Columbia Circuit overturned one of the Obama administration’s hallmark air-quality rules Tuesday, ruling that the Environmental Protection Agency had overstepped its authority in curbing pollution from power plants too sharply.
The 2 to 1 ruling by the appeals court represents a major victory for utilities and business groups, who fought the Cross-State Air Pollution Rule on the grounds that it was costly, burdensome and arbitrary. Environmentalists, who had hailed the rule as a major improvement over a Bush-era regulation, bemoaned the decision as a blow to public health.

By Charles Choi, LiveScience Contributor:
Earthquakes triggered by fluids injected deep underground, such as during the controversial practice of fracking, may be more common than previously thought, a new study suggests. ...
However, researchers have long known that fluid-injection operations can trigger earthquakes. For instance, in 2006 one geothermal energy site triggered four earthquakes in Basel, Switzerland, ranging from 3.1 to 3.4 on the Richter scale. Fracking also appears linked with Oklahoma's strongest recorded quake in 2011, as well as a spate of more than 180 minor tremors in Texas between Oct. 30, 2008, and May 31, 2009.
It remains unclear why some injection wells set off earthquakes whereas others do not. To find out, seismologist Cliff Frohlich at the University of Texas at Austin analyzed seismic activity in the Barnett Shale of northern Texas between November 2009 and September 2011 and compared the properties of injection wells located near quake epicenters. He relied on mobile seismometers deployed as part of the EarthScope USArray program over an approximately 23,000-square-mile (60,000 square kilometer) area.
Frohlich identified the epicenters for 67 earthquakes — more than eight times as many as reported by the National Earthquake Information Center — with magnitudes of 3.0 or less. Most were located within a few miles of one or more injection wells, suggesting injection-triggered quakes might be more common than thought.

By RICHARD A. MULLER Richard A. Muller, a professor of physics at the University of California, Berkeley, and a former MacArthur Foundation fellow, is the author, most recently, of "Energy for Future Presidents: The Science Behind the Headlines."
CALL me a converted skeptic. Three years ago I identified problems in previous climate studies that, in my mind, threw doubt on the very existence of global warming. Last year, following an intensive research effort involving a dozen scientists, I concluded that global warming was real and that the prior estimates of the rate of warming were correct. I'm now going a step further: Humans are almost entirely the cause.
My total turnaround, in such a short time, is the result of careful and objective analysis by the Berkeley Earth Surface Temperature project, which I founded with my daughter Elizabeth. Our results show that the average temperature of the earth's land has risen by two and a half degrees Fahrenheit over the past 250 years, including an increase of one and a half degrees over the most recent 50 years. Moreover, it appears likely that essentially all of this increase results from the human emission of greenhouse gases. ...
What about the future? As carbon dioxide emissions increase, the temperature should continue to rise. I expect the rate of warming to proceed at a steady pace, about one and a half degrees over land in the next 50 years, less if the oceans are included. But if China continues its rapid economic growth (it has averaged 10 percent per year over the last 20 years) and its vast use of coal (it typically adds one new gigawatt per month), then that same warming could take place in less than 20 years.
Science is that narrow realm of knowledge that, in principle, is universally accepted. I embarked on this analysis to answer questions that, to my mind, had not been answered. I hope that the Berkeley Earth analysis will help settle the scientific debate regarding global warming and its human causes. Then comes the difficult part: agreeing across the political and diplomatic spectrum about what can and should be done.

By Leonard David of Space.com, republished by MSNBC. "Mining the plentiful resources of the moon and near-Earth asteroids could alter the course of human history, adding trillions of dollars to the world economy and spurring our species' spread out into the solar system, a new breed of space entrepreneur says.
A number of private companies — such as the billionaire-backed asteroid-mining firm Planetary Resources — aim to start making all of this happen. But it won't be easy, as hitting extraterrestrial paydirt requires melding the know-how of the space and mining communities."

But since at least 1988, climate scientists have warned that climate change would bring, in general, increased heat waves, more droughts, more sudden downpours, more widespread wildfires and worsening storms. In the United States, those extremes are happening here and now.
So far this year, more than 2.1 million acres have burned in wildfires, more than 113 million people in the U.S. were in areas under extreme heat advisories last Friday, two-thirds of the country is experiencing drought, and earlier in June, deluges flooded Minnesota and Florida.
"This is what global warming looks like at the regional or personal level," said Jonathan Overpeck, professor of geosciences and atmospheric sciences at the University of Arizona. "The extra heat increases the odds of worse heat waves, droughts, storms and wildfire. This is certainly what I and many other climate scientists have been warning about."
Kevin Trenberth, head of climate analysis at the National Center for Atmospheric Research in fire-charred Colorado, said these are the very record-breaking conditions he has said would happen, but many people wouldn't listen. So it's I told-you-so time, he said.
As recently as March, a special report an extreme events and disasters by the Nobel Prize-winning Intergovernmental Panel on Climate Change warned of "unprecedented extreme weather and climate events." Its lead author, Chris Field of the Carnegie Institution and Stanford University, said Monday, "It's really dramatic how many of the patterns that we've talked about as the expression of the extremes are hitting the U.S. right now." ...
Since Jan. 1, the United States has set more than 40,000 hot temperature records, but fewer than 6,000 cold temperature records, according to the National Oceanic and Atmospheric Administration. Through most of last century, the U.S. used to set cold and hot records evenly, but in the first decade of this century America set two hot records for every cold one, said Jerry Meehl, a climate extreme expert at the National Center for Atmospheric Research. This year the ratio is about 7 hot to 1 cold. Some computer models say that ratio will hit 20-to-1 by midcentury, Meehl said.

In the classic Star Trek episode “Mirror, Mirror,” several members of the Enterprise crew inadvertently exchange places with their counterparts from an evil mirror universe.
Now two theoretical physicists have hypothesized that something like that may really be happening — at least with neutrons.
According to Science Daily, Zurab Berezhiani and Fabrizio Nesti of the University of l’Aquila in Italy analyzed experimental data obtained by a French research group which “showed that the loss rate of very slow free neutrons appeared to depend on the direction and strength of the magnetic field applied. This anomaly could not be explained by known physics.” [MORE]

BY STEPHEN CLARK, SPACEFLIGHT NOW Growing costs have forced NASA to cancel an X-ray astrophysics mission conceived to study intense gravity fields around black holes and collapsed stars, a senior agency official said Thursday. The Gravity and Extreme Magnetism, or GEMS, project did not pass a NASA confirmation review, a key decision point before the agency allows a mission to proceed into construction for flight, according to Paul Hertz, the space agency's astrophysics division director. "The GEMS project was initiated under a very well-defined cost cap," Hertz said Thursday. "As they approached their confirmation review, it was clear they would not be able to complete [the mission] within their cost cap."

Large majorities of Americans now favor all levels of government taking responsibility for addressing climate change, a University of Michigan study released Wednesday revealed. The Fall 2012 climate change survey, one of the National Surveys on Energy and Environment (NSEE), showed that 73% of respondents thought the federal government should take at least some responsibility for reducing greenhouse gases, 72% felt that state governments should also do so, and 68% wanted local governments to shoulder some or a great deal of the responsibility as well.
"This represents a significant increase in public support from the past two years for all levels of government to address climate change," said U-M Professor Barry Rabe, director of the Center for Local, State, and Urban Policy (CLOSUP) at U-M's Ford School of Public Policy in a press release. "This also coincides with findings of considerable support for some specific policy options to reduce greenhouse gases."

Swamp gas trapped under miles of Antarctic ice, a chemical souvenir of that continent's warmer days, may someday escape to warm the planet again, an international team of researchers report in Nature this week.
The researchers suggest that microbes isolated from the rest of the world since the ice closed over them, some 35 million years ago, have kept busy digesting organic matter and making methane—a much more effective greenhouse gas than carbon dioxide.
If global warming causes the ice sheets to retreat in the coming decades or centuries, the researchers warn, some of the methane could belch into the atmosphere, amplifying the warming.

by Nick Wing A group of Kentucky Republicans is up in arms over a state testing program that requires high school students preparing for college to have an understanding of biological evolution. When the Republican state legislature voted in 2009 to link the state's testing system to national education standards, it opened the door for biology exams that would test students' proficiency in the field of evolution. State Rep. Carl Rollins, a Democrat, told the Lexington Herald-Leader that this was standard practice, as ACT, the company that coordinates Kentucky's testing program, developed the material by surveying biology teachers across the country on which studies they believed should be included. They responded, rather unsurprisingly, that biological evolution was an important concept for incoming college students to grasp. But state Republicans are now recoiling at their decision. They claim it doesn't give the theory of creationism a fair shake and places undue emphasis on the teaching of evolution, which they maintain exists only as a "theory."

Physicists are rarely wealthy or famous, but a new prize rewarding research at the field’s cutting edges has made nine of them instant multimillionaires.
The nine are recipients of the Fundamental Physics Prize, established by Yuri Milner, a Russian physics student who dropped out of graduate school in 1989 and later earned billions investing in Internet companies like Facebook and Groupon.
"It knocked me off my feet," said Alan H. Guth, a professor of physics at the Massachusetts Institute of Technology who was among the winners. He came up with the idea of cosmic inflation, that there was a period of extremely rapid expansion in the first instant of the universe.
When he was told of the $3 million prize, he assumed that the money would be shared among the winners. Not so: Instead, each of this year’s nine recipients will receive $3 million, the most lucrative academic prize in the world. The Nobel Prize currently comes with an award of $1.2 million, usually split by two or three people. The Templeton Prize, which honors contributions to understanding spiritual dimensions of life, has been the largest monetary award given to an individual, $1.7 million this year.
The $3 million has already appeared in Dr. Guth's bank account, one that had had a balance of $200. "Suddenly, it said, $3,000,200," he said. "The bank charged a $12 wire transfer fee, but that was easily affordable."

IT'S past time to tell the truth about the state of the world’s coral reefs, the nurseries of tropical coastal fish stocks. They have become zombie ecosystems, neither dead nor truly alive in any functional sense, and on a trajectory to collapse within a human generation. There will be remnants here and there, but the global coral reef ecosystem - with its storehouse of biodiversity and fisheries supporting millions of the world’s poor - will cease to be. ...
But by persisting in the false belief that coral reefs have a future, we grossly misallocate the funds needed to cope with the fallout from their collapse. Money isn’t spent to study what to do after the reefs are gone — on what sort of ecosystems will replace coral reefs and what opportunities there will be to nudge these into providing people with food and other useful ecosystem products and services. Nor is money spent to preserve some of the genetic resources of coral reefs by transferring them into systems that are not coral reefs. And money isn’t spent to make the economic structural adjustment that communities and industries that depend on coral reefs urgently need. We have focused too much on the state of the reefs rather than the rate of the processes killing them. ...
This is not a story that gives me any pleasure to tell. But it needs to be told urgently and widely because it will be a disaster for the hundreds of millions of people in poor, tropical countries like Indonesia and the Philippines who depend on coral reefs for food. It will also threaten the tourism industry of rich countries with coral reefs, like the United States, Australia and Japan. Countries like Mexico and Thailand will have both their food security and tourism industries badly damaged. And, almost an afterthought, it will be a tragedy for global conservation as hot spots of biodiversity are destroyed.
What we will be left with is an algal-dominated hard ocean bottom, as the remains of the limestone reefs slowly break up, with lots of microbial life soaking up the sun’s energy by photosynthesis, few fish but lots of jellyfish grazing on the microbes. It will be slimy and look a lot like the ecosystems of the Precambrian era, which ended more than 500 million years ago and well before fish evolved.
Coral reefs will be the first, but certainly not the last, major ecosystem to succumb to the Anthropocene - the new geological epoch now emerging. That is why we need an enormous reallocation of research, government and environmental effort to understand what has happened so we can respond the next time we face a disaster of this magnitude. It will be no bad thing to learn how to do such ecological engineering now.

The North Carolina House of Representatives voted today to revise controversial legislation that would have barred state planning officials from considering the possibility that a changing climate might accelerate sea level rise. Climate scientists who had been highly critical of the former proposal gave a lukewarm reception to the changes, noting the bill still places a 4-year moratorium on the ability of planners to draw on the most up-to-date science.
"This version is better than the original Senate version," says climate researcher Robert Jackson of Duke University in Durham, North Carolina. "It's still bad policy though because it requires the state to bury its head in the sand for 4 more years."
Last month, North Carolina's Senate sparked controversy by approving language in legislation (HB 819) that would have required the state's Coastal Resources Commission (CRC), which sets rules and policies for coastal development and grants permits, to base predictions of future sea level rise along the state's coast on a steady, linear rate of increase. Critics argued that that would have prevented the commission from considering events, such as the melting of polar ice caps caused by increased global temperatures, which might accelerate the rate at which seas are expected to rise.

Over the past several decades, U.S. industries have injected more than 30 trillion gallons of toxic liquid deep into the earth, using broad expanses of the nation's geology as an invisible dumping ground.
No company would be allowed to pour such dangerous chemicals into the rivers or onto the soil. But until recently, scientists and environmental officials have assumed that deep layers of rock beneath the earth would safely entomb the waste for millennia.
There are growing signs they were mistaken.
Records from disparate corners of the United States show that wells drilled to bury this waste deep beneath the ground have repeatedly leaked, sending dangerous chemicals and waste gurgling to the surface or, on occasion, seeping into shallow aquifers that store a significant portion of the nation's drinking water. ...
But in interviews, several key experts acknowledged that the idea that injection is safe rests on science that has not kept pace with reality, and on oversight that doesn't always work.
"In 10 to 100 years we are going to find out that most of our groundwater is polluted," said Mario Salazar, an engineer who worked for 25 years as a technical expert with the EPA's underground injection program in Washington. "A lot of people are going to get sick, and a lot of people may die."
The boom in oil and natural gas drilling is deepening the uncertainties, geologists acknowledge. Drilling produces copious amounts of waste, burdening regulators and demanding hundreds of additional disposal wells. Those wells — more holes punched in the ground — are changing the earth's geology, adding man-made fractures that allow water and waste to flow more freely.
"There is no certainty at all in any of this, and whoever tells you the opposite is not telling you the truth," said Stefan Finsterle, a leading hydrogeologist at Lawrence Berkeley National Laboratory who specializes in understanding the properties of rock layers and modeling how fluid flows through them. "You have changed the system with pressure and temperature and fracturing, so you don't know how it will behave."

What does the belief divide mean for civil discourse in the U.S.?
By Robert Wright, The Atlantic
About half of Americans--46 percent, in the latestGallup Poll--believe human beings weren't created by evolution.
Over at the Daily Dish, Andrew Sullivan says this is a grave problem. "I simply do not know how you construct a civil discourse indispensable to a functioning democracy with this vast a gulf between citizens in their basic understanding of the world."
Over at Mother Jones, Kevin Drum says Andrew should calm down. "This 46% number has barely budged over the past three decades, and I'm willing to bet it was at least as high back in the 50s and early 60s, that supposed golden age of comity and bipartisanship. It simply has nothing to do with whether we can all get along and nothing to do with whether we can construct a civil discourse."
As the narrator of the old Certs commercial used to say: Stop! You're both right!

Planetary researchers bake cakes and shine shoes to raise awareness of declining budget. By Amber Dance, Nature Magazine It has come to this: planetary scientists across the United States hawked baked goods to the public on Saturday in an effort to drum up awareness of their field’s dwindling financial support. They were protesting plans in US President Barack Obama's 2013 budget request to cut 21% from NASA's planetary-science budget, and 38% from its Mars projects.
“The planetary programme is one of the shining examples of NASA at its best,” says Alan Stern, vice-president of research and development in the space science and engineering division at the Southwest Research Institute in Boulder, Colorado, who coordinated the nationwide Planetary Exploration Car Wash and Bake Sale. “We’re not asking for a raise, but we sure would prefer not to have such a steep cut.”
One site where scientists are becoming agitated is NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California, where many Mars missions are built and managed. As the lab held its annual open house on Saturday, planetary scientists from the California Institute of Technology (Caltech) in Pasadena and the University of California, Los Angeles enticed visiting space fans to stop outside the entrance for cupcakes and learn about the budget plight.
