Sen. Bernie Sanders has accepted an invitation to speak at the Vatican for a conference on social justice next week. The April 15 event, which will be hosted by the Pontifical Academy of Social Sciences, is scheduled to cover a number of the Democratic presidential hopeful’s signature campaign issues, including income inequality and the environment.

Sanders’ appearance at Vatican City will come just days before the New York primary on April 19.

“I am delighted to have been invited by the Vatican to a meeting on restoring social justice and environmental sustainability to the world economy,” Sanders announced in a statement on Friday.

“Pope Francis has made clear that we must overcome ‘the globalization of indifference’ in order to reduce economic inequalities, stop financial corruption, and protect the natural environment. That is our challenge in the United States and in the world.”

What would actually happen if we stopped eating so much meat?

What would actually happen if we stopped eating so much meat?

By on 23 Mar 2016commentsShare

If you follow the news about food, you’re no doubt aware that there’s a lot of concern over the impact of eating and raising meat, on both human health and the planet. A new study provides more to chew on: It suggests that if we halved our meat consumption by 2050, we could make huge emissions cuts and save millions of lives.

The Oxford University researchers who published their results in the Proceedings of the National Academy of Sciences don’t expect the whole world to suddenly switch to vegenaise. But they wanted to explore possible environmental and human health outcomes from different diets. So they started by assuming that more people in developing countries would be eating like meat-loving Americans — a logical assumption, since that’s the way the world is headed — then looked at what would happen if we somehow cut that projected meat consumption by half by the middle of this century.

Their conclusion: The world could cut greenhouse gas emissions from food (which currently make up a quarter of the total) by 29 percent, and save 5.1 million lives per year through reduced heart disease, cancer, stroke, and other illnesses associated with meat consumption.

Of course, this isn’t a one-size-fits-all kind of diet advice: There are places where livestock form an important part of the ecosystem, and where people are making real efforts to raise more sustainable meat. But for those of us with abundant food choices, this study provides more evidence that less meat makes more sense.

Use behavioral science to help fight climate change, says Obama executive order

Use behavioral science to help fight climate change, says Obama executive order

By on 16 Sep 2015commentsShare

When you hear “climate policy,” you probably think of things like carbon markets, the Clean Power Plan, and, if you got a lot of extra credit in high school, forestry and land use changes. You probably don’t think of things like computer pop-ups and government mailings — unless, of course, you’re part of the Obama administration’s Social and Behavioral Sciences Team (SBST). Which is kind of the point. The SBST, which is a little over a year old and released its first annual report yesterday, is all about making the kinds of policy tweaks you and I don’t notice: the minor, stealthy, behaviorally targeted tweaks with big payoffs.

And while many of these policy “nudges” often focus on areas like government efficiency, nutrition, and program uptake, a new executive order cites the behavioral sciences as holding great potential for complementing the administration’s efforts at meaningful climate action, too. “By improving the effectiveness and efficiency of Government,” states the executive order, “behavioral science insights can support a range of national priorities, including … accelerating the transition to a low-carbon economy.”

Can we actually nudge our way to a better climate? While not the primary solution, it’s perhaps useful to conceptualize these kinds of policy changes as rounding out the often “all-of-the-above” American approach to climate and energy policy. Here’s more, from ClimateWire:

The administration suggests that behavioral cues, like comparing your energy use with a neighbor, can be used to increase participation in energy efficiency and other federal goals. …

[Other methods include] a pop-up computer window that urges people to save paper by printing on both sides. The experiment resulted in a 5.8 percent increase in double-sided printing, a potentially significant reduction in the 18 billion pages printed annually by federal workers.

Let’s just pause for a moment and consider those 18 billion printed pages. How is that even physically possible? How many printers are in the Eisenhower Building? Do people have printers instead of desks? Has the White House somehow misunderstood the concept of a 3D printer? Is the White House made of paper?

If most of that printing is single-sided, a 5.8 percent increase in double-sided printing represents over A BILLION saved pages. JUST CHANGE THE DEFAULT SETTINGS, SHEEPLE.

Anyway. ClimateWire continues:

The administration also says climate-related programs could benefit. Behavioral changes being pursued by the Social and Behavioral Sciences Team could result in more people buying federal flood insurance, which suffers from low take-up rates. Public materials will be “redesigned to present information more clearly,” the White House said.

The team is also working on ways to increase energy efficiency in government buildings, in part by providing more access to daylight. And efforts are being designed to increase the use of renewable fuels in the federal fleet of vehicles, as well as encourage greater use of efficient appliances by communicating the benefits with homeowners.

The team’s annual report also announces the results of pilot projects related to college attendance and Affordable Care Act sign-ups. While many of the SBST’s policies target internal government operations, it’s not unreasonable to imagine uptake in broader public or private settings. Indeed, one year in, the SBST seems poised for success — if only at the margin. And with respect to climate change, we need all the help we can get closing the gap between current national commitments and the emission reductions necessary for keeping warming below 2 degrees C.

But seriously, 18 billion pages. Is there some obscure regulation that mandates printing in 72-point font?

How the universe began and how humanity will drown: A scientist’s to-do list

How the universe began and how humanity will drown: A scientist’s to-do list

By on 11 Aug 2015commentsShare

No pressure, scientists, but you just got your marching orders for the next 10 years, and, well, you’ve got your work cut out for you:

  1. Understand the origins of the universe (cosmic inflation, the quantum nature of gravity, the nature of everything, etc.)
  2. Figure out how life evolved in the Antarctic over the last 30 million years (seriously, who wants to live there?)
  3. Get a handle on what’s happening with those melting ice sheets that we keep hearing so much about (i.e. just tell us how this is all gonna end, so we can start writing apology letters to the future)

The National Academies of Sciences, Engineering, and Medicine just released this little ditty of a to-do list for scientists working on NSF-funded Antarctic and Southern Ocean research. Two of the three initiatives are directly related to climate change and how we and other living things are going to have to adapt to it. It’s certainly reassuring that the powers that be consider these issues as important as answering the age-old questions of where everything came from and what it all means, but at the same time, it pretty much just confirms that we’re totally screwed, right?

Here’s an overview of the priorities from a press release about the report:

The report proposes a major new effort called the Changing Antarctic Ice Sheets Initiative to investigate how much and how fast melting ice sheets will contribute to sea-level rise.  The initiative’s components include a multidisciplinary campaign to study the complex interactions among ice, ocean, atmosphere, and climate in key zones of the West Antarctic Ice Sheet, and a new generation of ice core and marine sediment core studies to better understand past episodes of rapid ice sheet collapse. …

A second strategic research priority is to understand from a genetic standpoint how life adapts to the extreme Antarctic environment.  For more than 30 million years, isolated Antarctic ecosystems have evolved to adapt to freezing conditions and dramatic environmental changes, and now must adapt to contemporary pressures such as climate change, ocean acidification, invasive species, and commercial fishing.  Sequencing the genomes and transcriptomes of critical populations, ranging from microbes to marine mammals, would reveal the magnitude of their genetic diversity and capacity to adapt to change.

In addition to being a vast natural laboratory, Antarctica has a dry, stable atmosphere that offers an ideal setting for astrophysical observations.  The report recommends a next-generation experimental program to observe cosmic microwave background radiation, the “fossil light” from the early universe.  This would include an installation of a new set of telescopes at the South Pole, as part of a larger global array, which will allow highly sensitive measurements that could detect signatures of gravitational waves.  Such observations might provide evidence that could confirm the theory of cosmic inflation and the quantum nature of gravity, as well as address other enduring questions about the nature of the universe.

Got that, scientists? We’re looking for how the universe started, how life evolved in some of the most extreme environments on Earth, and how the oceans are ultimately going to engulf us all in a merciless end. Talk to you in 10 years.

Why are we building a research center full of deadly diseases in the tornado capital of the world?

The United States eradicated foot-and-mouth disease from its borders in 1929. The virus, deadly to livestock, persists in more than 100 countries, though, and travels with ease. It is able to hitchhike on shoes, clothes, and tires. Airborne, it can travel almost 40 miles overland and almost 190 over open ocean. …

If the foot-and-mouth virus—or any other airborne danger—escaped from the lab, the air currents would likely carry it beyond where it could cause harm. An out-of-the-way location makes sense because no lab is risk free. In 2007, for instance, the foot-and-mouth virus escaped from Great Britain’s Pirbright Institute, one of the world’s leading laboratories studying animal disease, and set off an outbreak at a nearby farm.

So it is absolutely mind-boggling that Homeland Security has decided to move the lab, to be known as the National Bio and Agro-Defense Facility, to the Kansas State University campus in Manhattan, Kansas, smack in the middle of cattle country and Tornado Alley. Builders recently broke ground on the brand-new $1.25 billion dollar facility, which is set to be fully operational in 2022. It will include a biosafety level 4 lab, meaning one designed to handle deadly and exotic pathogens for which no vaccines or treatments exist. …

In 2010, the National Academy of Sciences conducted a risk assessment of Homeland Security’s first proposal for the Kansas lab and found a 70 percent probability that a foot-and-mouth virus release resulting in an outbreak would occur over the facility’s 50-year life span. In 2012, the National Research Council evaluated Homeland Security’s revised proposal and found considerable improvements in lab construction design that lowered the 50-year risk to below 1 percent, but this extremely low probability of accidental viral release was based on Homeland Security’s unsupported, overly optimistic estimates of human error rates.

Thawing permafrost could be the worst climate threat you haven’t heard of

Thawing permafrost could be the worst climate threat you haven’t heard of

By on 3 Apr 2015commentsShare

Some things get better when you take them out of the freezer. Ice cream, for example, is unarguably more delicious when it gets a little melt-y. (Unarguably, I say! Come at me, trolls.) But other things get remarkably worse. Take bananas — the next time you whip up a smoothie, leave the frozen banana to defrost on your counter and watch in horror as it turns into a yellowish brown pile of watery mucus.

And then there’s permafrost: You don’t even want to know what happens to that shit when it thaws … but actually, it’s pretty important when it comes to climate change, so let’s talk about it.

Permafrost is basically soil that stays frozen all year long. Because it never melts, it holds thousands of years worth of dead plants and their carbon. About 24 percent of land in the Northern Hemisphere is covered with the stuff. But here’s Chris Mooney at the Washington Post on what might happen to all that frozen dirt as the earth gets warmer:

As permafrost thaws, microbes start to chow down on the organic material that it contains, and as that material decomposes, it emits either carbon dioxide or methane. Experts think most of the release will take the form of carbon dioxide — the chief greenhouse gas driving global warming — but even a small fraction released as methane can have major consequences. Although it doesn’t last nearly as long as carbon dioxide in the atmosphere, methane has a short-term warming effect that is many times more powerful.

So, Mooney explains, thawing permafrost would classify as one of those juicy “positive feedback” cycles that make climate change so exciting in that life-is-an-action-movie-and-someone-will-save-us-in-the-end-right?-RIGHT?!! sort of way:

More global warming could cause more thawing of Arctic permafrost, leading to more emissions of carbon into the atmosphere, leading to more warming and more thawing of Arctic permafrost — this does not end in a good place.

According to the National Academy of Sciences, the amount of carbon stored in northern permafrost (1,800 billion tons) is more than double the amount that’s currently in the atmosphere (800 billion tons).

Kevin Schaefer, a scientist with the National Snow and Ice Data Center at the University of Colorado in Boulder, told Mooney that the latest IPCC climate projections didn’t account for thawing permafrost because this area of research is relatively new. Still, early estimates show that permafrost could be emitting an average of 160 billion tons of carbon per year by the end of the century.  Which would be bad since, according to the National Academy of Sciences, we need to keep atmospheric carbon below 1,100 billion tons if we want to limit warming to 2 degrees Celsius.

Of course, this is climate science, so uncertainties abound. As Schaefer pointed out, scientists are only beginning to understand the implications of thawing permafrost. Still, it seems like something worth paying attention to … kind of like that pile of watery banana-mucus you left on your kitchen counter.

One Weird, Nobel Prize-Winning Trick That Could Halve America’s Lighting Bill

Mother Jones

On Tuesday, the Royal Swedish Academy of Sciences announced the winners of the Nobel Prize in Physics. In the first of the prestigious awards to be handed out this week, Japanese scientists Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura were honored for their invention of the blue light-emitting diode commonly known as an LED. The $8 million prize “rewards an invention of greatest benefit to mankind”—and LEDs have crossed the bar.

Invented just twenty years ago, blue LEDs paved the way for many now-common devices, like television LCD-screens, Blu-ray discs, and laser printers. But more importantly, they give off white light in a new, more efficient way, reducing energy consumption the world over.

Johan Jarnestad/The Royal Swedish Academy of Sciences

“I (was) not too sure whether I could win a Nobel Prize,” Shuji Nakamura said in a telephone interview after he was informed of the award. “Basically physics, it means that usually people was awarded for the invention of the basic theory. But in my case, not a basic theory. In my case just making the device, you know?”

In traditional electric lighting, most of the energy is lost when it is converted to heat. But LEDs convert electricity directly to light.

The invention was based on over three decades of work and research. And since their discovery in the early ’90s, the technology has rapidly improved: state of the art LEDs are now over four times more efficient than florescents and almost 20 times more efficient than regular light bulbs. Because they last so much longer, LEDs are also less wasteful.

Lighting accounts for about a quarter of the world’s energy consumption. The Climate Group, a nonprofit pushing LED use worldwide, reports that illumination is responsible for over 1,900 million tons of CO2 emissions every year. They calculate that number could be reduced by up to 70 percent, just by replacing traditional streetlamps with LED powered versions.

Created by The Climate Group

Last year, the US Department of Energy released a report saying LEDs could halve the country’s usage of electricity for lighting by 2030. The savings would equal the output of fifty 1,000 megawatt power plants, and reduce greenhouse gas emissions as much as taking 40 million cars off the road—not to mention cutting energy bills by $30 billion.

Of course there are still technical developments and obstacles to be overcome before this vision is realized. But it is not far fetched or far off, thanks to the latest Nobel laureates. To learn more about the science behind their world-changing invention (or to send them a quick congratulatory note!) you can head to the prizes’ site.

Scientists Are Beginning To Figure Out Why Conservatives Are…Conservative

Mother Jones

<!DOCTYPE html PUBLIC “-//W3C//DTD HTML 4.0 Transitional//EN” “http://www.w3.org/TR/REC-html40/loose.dtd”>

You could be forgiven for not having browsed yet through the latest issue of the journal Behavioral and Brain Sciences. If you care about politics, though, you’ll find a punchline therein that is pretty extraordinary.

Behavioral and Brain Sciences employs a rather unique practice called “Open Peer Commentary”: An article of major significance is published, a large number of fellow scholars comment on it, and then the original author responds to all of them. The approach has many virtues, one of which being that it lets you see where a community of scholars and thinkers stand with respect to a controversial or provocative scientific idea. And in the latest issue of the journal, this process reveals the following conclusion: A large body of political scientists and political psychologists now concur that liberals and conservatives disagree about politics in part because they are different people at the level of personality, psychology, and even traits like physiology and genetics.

That’s a big deal. It challenges everything that we thought we knew about politics—upending the idea that we get our beliefs solely from our upbringing, from our friends and families, from our personal economic interests; and calling into question the notion that in politics, we can really change (most of us, anyway).

The occasion of this revelation is a paper by John Hibbing of the University of Nebraska and his colleagues, arguing that political conservatives have a “negativity bias,” meaning that they are physiologically more attuned to negative (threatening, disgusting) stimuli in their environments. In the process, Hibbing et al. marshall a large body of evidence, including their own experiments using eye trackers and other devices to measure the involuntary responses of political partisans to different types of images. One finding? That conservatives respond much more rapidly to threatening and aversive stimuli (for instance, images of “a very large spider on the face of a frightened person, a dazed individual with a bloody face, and an open wound with maggots in it,” as one of their papers put it.)

In other words, the conservative ideology, and especially one of its major facets—centered on a strong military, tough law enforcement, resistance to immigration, widespread availability of guns—would seem well tailored for an underlying, threat-oriented biology.

The authors go on to speculate that this ultimately reflects an evolutionary imperative. “One possibility,” they write, “is that a strong negativity bias was extremely useful in the Pleistocene,” when it would have been super helpful in preventing you from getting killed. (The Pleistocene epoch lasted from roughly 2.5 million years ago until 12 thousand years ago.) We had John Hibbing on the Inquiring Minds podcast earlier this year, where he discussed these ideas in depth; you can listen here:

Hibbing and his colleagues make an intriguing argument in their latest paper, but what’s truly fascinating is what happened next. Twenty-six different scholars or groups of scholars then got an opportunity to tee off on the paper, firing off a variety of responses. But as Hibbing and colleagues note in their final reply, out of those responses, “22 or 23 accept the general idea” of a conservative negativity bias, and simply add commentary to aid in the process of “modifying it, expanding on it, specifying where it does and does not work,” and so on. Only about three scholars or groups of scholars seem to reject the idea entirely.

That’s pretty extraordinary, when you think about it. After all, one of the teams of commenters includes New York University social psychologist John Jost, who drew considerable political ire in 2003 when he and his colleagues published a synthesis of existing psychological studies on ideology, suggesting that conservatives are characterized by traits such as a need for certainty and an intolerance of ambiguity. Now, writing in Behavioral and Brain Sciences in response to Hibbing roughly a decade later, Jost and fellow scholars note that

There is by now evidence from a variety of laboratories around the world using a variety of methodological techniques leading to the virtually inescapable conclusion that the cognitive-motivational styles of leftists and rightists are quite different. This research consistently finds that conservatism is positively associated with heightened epistemic concerns for order, structure, closure, certainty, consistency, simplicity, and familiarity, as well as existential concerns such as perceptions of danger, sensitivity to threat, and death anxiety. Italics added

Back in 2003, Jost and his team were blasted by Ann Coulter, George Will, and National Review for saying this; congressional Republicans began probing into their research grants; and they got lots of hate mail. But what’s clear is that today, they’ve more or less triumphed. They won a field of converts to their view and sparked a wave of new research, including the work of Hibbing and his team.

Granted, there are still many issues yet to be worked out in the science of ideology. Most of the commentaries on the new Hibbing paper are focused on important but non-paradigm shifting side issues, such as the question of how conservatives can have a higher negativity bias, and yet not have neurotic personalities. (Actually, if anything, the research suggests that liberals may be the more neurotic bunch.) Indeed, conservatives tend to have a high degree of happiness and life satisfaction. But Hibbing and colleagues find no contradiction here. Instead, they paraphrase two other scholarly commentators (Matt Motyl of the University of Virginia and Ravi Iyer of the University of Southern California), who note that “successfully monitoring and attending negative features of the environment, as conservatives tend to do, may be just the sort of tractable task…that is more likely to lead to a fulfilling and happy life than is a constant search for new experience after new experience.”

All of this matters, of course, because we still operate in politics and in media as if minds can be changed by the best honed arguments, the most compelling facts. And yet if our political opponents are simply perceiving the world differently, that idea starts to crumble. Out of the rubble just might arise a better way of acting in politics that leads to less dysfunction and less gridlock…thanks to science.

No, the IPCC climate report doesn’t call for a fracking boom

No, the IPCC climate report doesn’t call for a fracking boom

You might have heard that the latest installment of the big new U.N. climate report endorses fracking, urging a “dash for gas” as a bridge fuel to put us on a path to a more renewable energy future. These interpretations of the report are exaggerated, lack context, and are just plain wrong. They appear to have been based on interviews and on a censored summary of the report, which was published two days before the full document became available.

The energy chapter from the full report of the Intergovernmental Panel on Climate Change says “near‐term GHG emissions from energy supply can be reduced” by replacing coal-fired power plants with “highly efficient” natural gas–burning alternatives — a move that “may play a role as a transition fuel in combination with variable renewable sources.” But that’s only true, the report says, if fugitive emissions of climate-changing methane from drilling and distribution of the gas are “low” — which is far from the case today. Scientists reported Tuesday in the Proceedings of the National Academy of Sciences that methane measurements taken near fracking sites in Pennsylvania suggest such operations leak 100 to 1,000 times more methane than the U.S. EPA has estimated. The IPCC’s energy chapter also notes that fracking for gas has “created concerns about potential risks to local water quality and public health.”

To protect the climate and save ourselves, the new IPCC report says we must quit fossil fuels. That doesn’t mean switching from coal to natural gas. It means switching from coal and gas to solar and wind, plugging electric vehicles into those renewable sources, and then metaphorically blowing up the fossil-fueled power plants that pock the planet.

Stabilizing greenhouse gas concentrations at “low levels” requires a “fundamental transformation of the energy supply system,” the IPCC says. Overall, its latest report concludes that we must reduce greenhouse gas emissions by 40 to 70 percent by midcentury, and stop producing any such pollution by the turn of the century, if we’re to keeping warming to within 2 degrees Celsius, or 3.7 F. And nothing is more important in meeting those goals than revolutionizing the way we produce electricity. Humanity’s thirst for electricity is the biggest single cause of climate change, with the energy sector fueling a little more than a third of global warming.

Wind, solar, hydro, and other renewable forms of energy account for a little more than half of all new generating capacity being built around the world, the report says. But that is not enough. The report notes that renewable energy still requires government support, such as renewable portfolio standards and prices and caps on carbon emissions.

But, as desperately as we need to be curbing fossil-fuel burning, we just keep increasing it instead. Greenhouse gas emissions from the energy sector rose 3.1 percent every year from 2001 to 2010. In the 1990s, they rose just 1.7 percent annually. “The main contributors to this trend were a higher energy demand associated with rapid economic growth and an increase of the share of coal in the global fuel mix,” the report states.

Of course, slaking our thirst for electricity with renewables wouldn’t just be good for the climate. The energy chapter highlights “co-benefits” from the use of renewable energy, “such as a reduction of air pollution, local employment opportunities, few severe accidents compared to some other forms of energy supply, as well as improved energy access and security.”

A revolution doesn’t sound so scary when you put it that way.

Oh rot: Climate change could topple Northwest’s Douglas fir forests

Oh rot: Climate change could topple Northwest’s Douglas fir forests

BLM

Root-rotting fungi have lived among the Douglas firs of the Pacific Northwest for thousands of years — perhaps since the last ice age. They’re an invisible part of the sweeping forest scenery, ready to fell a sick tree or feast on a dead one.

But, in case you haven’t noticed, things have been going a tad crazy with the environment lately. Douglas firs in the Pacific Northwest have been dying, costing the timber industry millions of dollars a year. Some have been killed by beetle attacks; others by fungal diseases. Tree die-offs in the region have become so bad that scientists fear the natural carbon sink — that is, a place where plants pull carbon dioxide out of the atmosphere — is turning into a net emitter of the greenhouse gas.

And scientists fear the problem will grow worse as the globe continues to warm. A new report warns that climate change threatens to usher in an era of unprecedented root-rotting fungus infestations.

“Root diseases in managed western forests are a major contributor to the loss in timber productivity, revenues, and environmental benefits — negative impacts that will likely continue to increase, especially in the context of climate change,” states the report, which was published by the Washington State Academy of Sciences. “Anticipated climate change could increase the spread rate of the pathogen as well as host susceptibility.”

Laminated root rot, one of several major tree diseases caused by fungi in the region, is already thought to be reducing timber harvests by 5 to 15 percent. Warming temperatures combined with reduced snow and rainfall are forecast for the North American range of Douglas firs, and that’s expected to further “stress” the trees. Fungal pathogens tend to prey on weak individuals.

“Additional host stress is the primary driver of the assumption that diseases such as laminated root rot will increase,” Karen Ripley, a forest health manager with the Washington Department of Natural Resources, told us. “Because the host tree is likely to be more moisture stressed, the fungus may be more able to overcome host defenses, and the host may be less able to compensate for loss of roots.”

Even if the fungus doesn’t kill directly, an attack can leave trees vulnerable to fire, to beetles, or to toppling over in strong winds — and climate models warn of stronger wind storms in the region. Some dead trees are good for a forest, as they provide holes used for nests by birds and other wildlife. But trees killed by fungus tend to fall over and break down quickly.
