First mammal goes extinct because of climate change

By on Jun 14, 2016Share

Pour one out for the melomys: the first mammal in recorded history to go extinct thanks to climate change.

Wait, the memonly-lemony what? Get ready for a spit take, because the Bramble Cay melomys is — excuse me, was — a rat.

An upstanding resident of a tiny, isolated island in the Great Barrier Reef, the rodent spent its days minding its own business: scrambling through herbaceous vegetation, foraging for succulents, and treating itself to the occasional turtle egg. That is, until the ocean indiscriminately swallowed up its low-lying coral cay, which — it turns out — is a very effective form of pest control.

A recent report from the University of Queensland confirmed that climate change was the root cause of the melomys’ eradication: Sea levels rose at twice the rate of the global average in the waters surrounding Bramble Cay, drenching a full 97 percent of the melomys’ habitat between 2004 and 2014.

Though it may be the first mammal officially to disappear due to climate change, the melomys is far from the last. Our changing climate is on track to wipe out up to one-sixth of the species on this planet, according to a 2015 study.

But of all the species dead or alive, I think it’s fair to say the poor melomys is the most like a drowned rat. Goodbye, dear melomys: We only learned of your existence today, but we’re sorry we missed our chance to meet you!

Why I Am Vegan (And You Should Be Too)

Since the vegan movement started in the 1940s, it has been mainly about ending the exploitation of animals. While veganism has grown in numbers throughout the decades, lets face it: most people simply dont care about animals enough to stop using them as food. But animal welfare is only one reason to go vegan. Other than the animals, here are some of the many reasons why I am vegan and you should be too.

Veganism Is Feminism

Veganism is based on the principle of speciesism, or the belief that no species (in this case, humans) is inherently superior to another species.

This concept is closely related to sexism, as well as racism, classism, ableism, heterosexualism, and the other isms that plague society. If you allow the belief that humans are superior to animals and thus it is okay to exploit them, then you make room for the belief that men are superior to women and so forth. To quote Alice Walker, author of The Color Purple:

The animals of the world exist for their own reasons. They were not made for humans any more than black people were made for whites or women for men.

Veganism Is Good for the Planet

Unless youve been solely tuned to Fox News, you are probably aware by now that global warming is a serious problem. The 2014 UN report on climate change said that we can expect famine, drought, and wars over resources by 2050 if climate change isnt halted.

While the media focuses on things like taking shorter shower and using public transportation as a way to curb the eminent doom that is global warming, they often fail to mention what really needs to be done, which is to change the way we eat.

It will be hard to meet the 2-degree goal no matter what; it will be impossible if livestock pollution isn’t part of the mix, Doug Boucher, PhD ecologist and evolutionary biologist and director of climate research and analysis at the Union of Concerned Scientists told CNN,

How bad is meat and dairy for the planet? According to FAO, 18 percent of global emissions come from livestock. Lindsay Wilson fromShrink that Footprintlooked at the eco footprints of various diets in America, and he found that the average American has a footprint of 2.5 tCO2e per year (tons of carbon dioxide equivalent) and a meat lover has a footprint of 3.3 tCO2e. By contrast, a vegan footprint is just 1.5 tCO2e!

Or, to put this in terms of water usage,1lb of beef requires 1,800gallons of water. Do the math and youll see that the water used to make 10 hamburgers is well over a years worth of showers.

Yes, you could quit showering for an ENTIRE YEAR and still not save as much water if youd just stop eating meat.

Veganism Is Good for Your Health

Yes, there are some nutritional issues about the vegan diet which need to be considered (but protein isnt one of them!). And, yes, it is possible to eat nothing but junk food and still be vegan. However, numerous studies have shown that the vegan diet is linked to numerous health benefits, including:

Lower Body Weight: People who eat meat are 9 times more likely to be obese than vegans.
Reduced Risk of Heart Disease: Vegans are 32 pecent less likely to get heart disease.
Diabetes: Vegans have half the risk of developing type II diabetes as meat eaters.

So, even if you dont care about animal welfare, go vegan for your fellow man (and woman) kind, the planet, and for yourself!

4 reasons Alberta’s wildfire is such a nightmare

4 reasons Alberta’s wildfire is such a nightmare

By on May 10, 2016Share

Officials say the massive wildfire raging across Canada’s oil capital of Alberta will take months to extinguish. The fire has already destroyed 24,000 buildings in Fort McMurray and forced nearly 90,000 people to flee their homes, but what’s making it so hard to control?

It seems the “perfect storm” trope is appropriate here. Or, as Slate’s Eric Holthaus wrote, there’s a “messy mix of factors” behind the fire:

Land temperature anomalies from NASA satellite data April 26 to May 3, 2016.

  1. Humans. High temperatures, little rain help fuel a longer and larger-than-life wildfire season, and each are symptoms of climate change. But it’s possible the fire itself was manmade: Though the exact cause is unknown, according to The Canadian Press, “the fire’s proximity to the city, as well as data that shows there were no lightning strikes in the area” led a fire researcher to believe that human activity set off the initial spark.
  2. El Niño. The region’s exceptionally dry winter and prolonged drought is linked to a major El Niño, which turned the forests around Fort McMurray into a “tinderbox.” Of course, climate change exacerbates El Niño extremes.
  3. The forest. Fort McMurray is best known for its proximity to tar sands oil fields (which drove up its population in the last decade, during the oil boom). It is also surrounded by boreal forests that are really, really dry after the last few years. How could that get even worse? Well, by the species of trees that populate the area — black and white spruce — which are especially prone to spreading fire, reports the The Globe & Mail.
  4. The wind. Winds of 37 miles per hour over almost doubled the size of the blaze last weekend.

If there’s one thing that didn’t cause this fire, it’s karma. Seriously, why would anyone gloat that an oil town in tar sands country is getting leveled by a climate-induced disaster? As The New Yorker’s Elizabeth Kolbert notes, “we’ve all contributed to the latest inferno” because we all guzzle oil, not to mention gas and coal.

The irony is while entire communities have been destroyed by the fire, oil sands and energy facilities have remained pretty much intact.

Why Does the Supreme Court Matter to Environmentalists?

One of the hottest issues in any presidential race usually has to do with the Supreme Court, the highest court in the U.S. The 9 justices who sit on the court hold the fate of the nation in their hands. They decide lawsuits, interpret the Constitution and can change the way society is forced to behave, simply by reaching a majority decision on a case that’s brought before them.

The President nominates justices, and the U.S. Senate votes them in or out. Once appointed, a Supreme Court justice serves a life term that ends only when the justice dies or voluntarily resigns. Because a justice can stay on the court for 30 or 40 years, many people believe that of the thousands ofdecisions a president makes during his or her tenure, the nomination of a Supreme Court justice is among the most important.

Supreme Court decisions have determined whether and how the environment is protected for many decades. Here is a sample of some important decisions the court has made regarding the planet.

Endangered Species – Antonin Scalia, who recently died after 30 years as a justice, led the court’s conservative wing on limiting environmental groups’ ability to sue corporate polluters, protect public land and enforce federal water regulations.

Environmentalists use lawsuits to force polluters to obey state and federal laws on such issues as releasing toxic chemicals into the air or waterways or to protect endangered species. Scalia’s 1992 opinion in

Lujan v. Defenders of Wildlife

determined that Defenders (ergo, other environmental organizations) did not have “standing” to challenge endangered species protections. In other words, the Court essentially decided, in an

opinion written by Scalia

, that industry attempts to blockthe Endangered Species Act should be taken more seriously than environmental groups’ efforts to enforce it.

Clean Power Plan

– President Obama and the U.S. Environmental Protection Agency have issued a rule requiring states to develop plans to lower carbon dioxide emissions from power plants. The

CPP

is an attempt to reduce greenhouse gases that cause climate change as well as limit soot and other fine particles that contribute to air pollution.

The current court has

blocked

the government’s ability to implement the plan because opponents have filed a lawsuit in the D.C. Circuit Court, which will hear arguments about the law pros and cons June 2. If the D.C. Circuit Court upholds the constitutionality of the plan, opponents could stillappeal to the Supreme Court, which could decide the plan is unconstitutional. The fate of the Clean Power Plan remains to be seen.

Mercury Pollution – Coal and oil-fired power plants emit mercury and other air pollutants. In fact, coal plants are the largest single source of mercury in our environment.

The Environmental Protection Agency issued a federal rule aimed at reducing mercury emissions. That

rule was challenged

by twenty states that wanted the court to block the rule while the government decided how to calculate the cost of implementing it.

In a good move for the planet, Chief Justice John Roberts turned down their request and let the rule stay in effect while the costs are determined.

Citizens United

– In 2010, the Supreme Court decided in the

Citizens United Case

that corporations and labor unions can contribute unlimited amounts of money to candidates running for office. The Court also essentially gave permission to polluters todonate huge sums to sitting legislatorsin the hopes of influencing the votes they cast on new laws to protect the environment.

Here is one example of how Citizens United has played out. Richmond, California in the San Francisco Bay Area is the home of a Chevron oil refinery. Prior to Citizens United, perhaps around $100,000 would have been spent on local political races there. But in 2012, reports

Garnet Goes Green,

political action committees empowered by Citizens United poured $4 million into the races for three seats on the Richmond City Council. Of that, $2 million was contributed by Chevron.

Results? Two of Chevron’s three preferred candidates won their races in that year’s election.

Citizens United reaches far beyond the environment. The

U.S. Library of Medicine

, a division of the National Institutes of Health, has found that “corporations can now make unlimited contributions to election advocacy advertising…Candidates who favor public health positions may be subjected to corporate opposition advertising.” In other words, polluters can spend a fortune trying to defeat a candidate who wants to clean up the air or water or reduce the presence of toxic chemicals in everyday products.

“The ruling expands corporate rights to disproportionately influence the electoral process and thus health policymakers,” notes the National Library of Medicine. “The effects on public health may be catastrophic. For example, corporations could spend unlimited sums for advertising against candidates who support public health positions on issues such as taxation on sugar-sweetened drinks, air quality standards or access to reproductive services.”

The environment always seems to be under attack. Often, our only recourse is to sue to invoke protections afforded the planet by suchlaws as the Clean Air Act, the Clean Water Act or

NEPA

, the National Environmental Policy Act.

The buck stops with the Supreme Court. However justices interpret the law, whether to protect the environment or protect the polluters, will reverberate across the planet for decades to come. The Supreme Court can be our last best hopeor our worst one.

These species survived the last ice age but couldn’t survive people

These species survived the last ice age but couldn’t survive people

By on 20 Oct 2015commentsShare

Screw Myers and Briggs. I’ve got a new personality test for you.

Read the following statement and choose the response that most accurately depicts how it makes you feel:

Statement: Ten thousand years ago, 22 species of birds, reptiles, and mammals on the Bahamian island of Abaco miraculously survived the rising seas and shifting climate at the end of the last ice age. Then, 1,000 years ago, humans showed up and took them out like trash on pick-up day.

Responses: A) Damn right! Humans are and forever will be the masters of this planet. B) Humans are everything that’s wrong with this world, and the sooner we die off, the better. C) Interesting … I wonder why this happened and what it means for species now dealing with both humans and climate change.

Now, based on the Psych 101 class that I took in college, here are your results: If you answered A, then you’re a psychopath; if you answered B, then you’re not helping; and if you answered C, then congratulations! You’re thinking like a scientist.

In a recent study published in the Proceedings of the National Academy of Sciences, University of Florida researchers report that out of 100 species analyzed from fossils found in a flooded cave on Great Abaco Island, 17 bird species went extinct around the end of the last ice age, while 22 bird, reptile, and mammal species survived, only to succumb to humans a few thousand years later.

Here’s more from a University of Florida press release:

For species that were lost at the end of the ice age, climate change, habitat change and rising seas, with resulting smaller islands, may have caused their populations to become too small to remain genetically viable, resulting in inbreeding, (lead author Dave) Steadman said. A January 2015 study co-authored by Steadman found the Caribbean’s first humans depleted species as small as bats on Abaco. The new study shows several other species that endured until human arrival were lost to activities such as hunting and starting wildfires, he said.

The researchers plan to go back to the island later this year to study more fossils and get a broader picture of who died of what and why, according to the press release.

“What we see today is just a small snapshot of how species have existed for millions of years,” Steadman said. “The species that existed on Abaco up until people arrived were survivors. They withstood a variety of environmental changes, but some could not adapt quickly or drastically enough to what happened when people showed up.

“So, there must be different mechanisms driving these two types of extinctions. What is it about people that so many island species could not adapt to? That’s what we want to find out.”

What is it about people? I ask myself that same question every day on my way to work. Does that make me a sociopath? Who knows — I’ve only taken Psych 101. Either way, hit me up when you find the answer, Steadman.

Humans really are unprecedented in Earth’s geological history — and that’s a bad thing

Humans really are unprecedented in Earth’s geological history — and that’s a bad thing

By on 29 Jun 2015commentsShare

There’s no doubt that a) humans have messed up the planet big time and b) our ability to maintain our sanity while barreling toward an uncertain and potentially catastrophic future is perhaps our greatest achievement of all time. But in a new study from the latest issue of The Anthropocene Review, researchers explain just how much we’ve f-ed up this beautiful world.

“We think of major changes to the biosphere as the big extinction events, like that which finished off the dinosaurs at the end of the Cretaceous Period. But the changes happening to the biosphere today may be much more significant,” Mark Williams, a geologist from the University of Leicester and leader of the study, said in a press release.

Indeed, Williams and his colleagues claim that not since the evolution of photosynthetic microbes or multicellular animals has the course of Earth’s ecosystem changed so much. Scientists already acknowledge that we’ve entered a new human-induced geological epoch called the Anthropocene (although they disagree on when it began).

“But what is really new about this chapter in Earth history, the one we’re living through?” Williams says in the press release. “Episodes of global warming, ocean acidification and mass extinction have all happened before, well before humans arrived on the planet. We wanted to see if there was something different about what is happening now.”

Here are the four key changes from the press release, that they say define this unprecedented time in Earth’s history:

The homogenisation of species around the world through mass, human-instigated species invasions — nothing on this global scale has happened before

One species, Homo sapiens, is now in effect the top predator on land and in the sea, and has commandeered for its use over a quarter of global biological productivity.  There has never been a single species of such reach and power previously

There is growing direction of evolution of other species by Homo sapiens

There is growing interaction of the biosphere with the ‘technosphere’ — a concept pioneered by one of the team members, Professor Peter Haff of Duke University — the sum total of all human-made manufactured machines and objects, and the systems that control them

On the plus side, if humanity is headed for demise, at least we’re going out with a bang — like that drunk guy who gets tossed out of the bar and triumphantly knocks down every chair on his way to the door.

If you’re feeling overwhelmed by climate change news, don’t — I repeat, DO NOT — stop to smell the roses. Because they are probably more overwhelmed than you: Scientists in California can see the effects of climate change in fields of flowers, which are losing species diversity as winters get warmer and drier, according to one new study.  Flowers are pretty, colorful dabs of joy that never hurt anyone, and climate change is killing them — welcome back to Spoiler Alerts.

Here’s the story from the LA Times:

Over time, the researchers noticed that the big, intense blooms of wildflowers that used to appear in the spring were becoming less and less frequent. So they decided to analyze changes in plant species over time.

They picked 80 different sites from all over the reserve and counted all of the species growing in five small plots at each site. They also estimated how much area each plant species covered within each plot.

The research team correlated changes in plant growth with changes in rainfall patterns, temperature, cloud cover and humidity.

Across all 80 sites, clusters of native wildflower species became increasingly less diverse from 1999 to 2014, the researchers found. In particular, the species that were disappearing fastest were those with broad leaves, which are most susceptible to drought.

The 15% decline in wildflower species diversity was correlated with about 50% less rain in midwinter, about 20% more sun in fall and winter, and a 20% drop in winter humidity.

You know comes next, right? “Correlation is not causation,” yeah yeah — but this study offers powerful evidence of changes in ecosystem makeup at the local level. What, do you think this is these scientists’ first science rodeo? (Go ahead and picture those lab-coated rodeo clowns anyway.) More from the LA Times:

To take account of other factors that might affect plant diversity, the researchers made sure about half of the sites were in areas with fertile soils, no grazing and no recent history of fire. The other sites had inhospitable soils, occasional grazing and had burned in 1999. Even when these variables were considered in their model, the link between climate change and wildflower growth held up.

Hope you guys like wild grasses, because it looks like that’s what we’ll have left.

File this under “superlatives you have never considered awarding before” — here’s the most adorable primer on extinction you’ve ever seen.

A British design firm made the “Species in Pieces” exhibition to showcase 30 “of the world’s most interesting but unfortunately endangered species.” Over a meditatively mournful piano track, the animals assemble and disassemble from a series of animated triangles. Click through, and you get facts about the threats facing each delightful creature, statistics about remaining populations, and videos of the real-life animals swimming or crawling or rolling adorably around.

On the hit list are cuties like the vaquita, a tiny dolphin that lives (for now) in the Gulf of Mexico. Newborns, as the site adorably informs us, are “the size of a loaf of bread,” and constantly look like they’re smiling.

The vaquita.

Bryan James

Then there’s the three-banded Brazilian armadillo, just returned from a tour of duty as the 2014 FIFA World Cup mascot. It may be an endearing match for jaguars and athletes’ feet alike — not to mention our hearts — but it doesn’t stand a chance against habitat loss and climate change.

Brazilian armadillo. Bryan James

The list goes on, with teeny golden frogs and wee pygmy sloths and the squee-worthy forest owlet. Like a lot of awareness-raising art, it’s not clear what we should do or feel at the end of a project like this. So until I can think up something more productive, I’ll just settle for a combination of swooning and sobbing and watching slow loris video compilations. Please, join me.

Sneakerheads’ souls crumble as their soles crumble

Sneakerheads’ souls crumble as their soles crumble

By on 18 May 2015commentsShare

Sneakerheads are in the midst of a crisis, as they watch their prized possessions — those sick kicks they’ve been coveting for years — literally fall apart in their hands.

Turns out, those old-school Nikes are so out-of-this-world, they actually can’t survive Earth’s atmosphere. Wired has the scoop, and it’s truly heartbreaking. Take the story of Nagomo Oji, a Japanese sneakerhead who decided to whip out his DS/OG Air Max 95s with midsole BWs (DS = dead stock; OG = original; DS/OG = $$; BW = big window) after 20 years:

As soon as he planted his feet, Oji sensed something was terribly wrong. The midsoles flattened, and his footing became strangely unstable. He didn’t realize it at the time, but the polyurethane (PU), that squishy, shock-absorbing material sandwiched between the upper and the outer sole, was more than ten years past its projected lifespan.

After just one step, the hardened PU foam fractured and collapsed, like arid soil crumbling beneath the boots of a Dust Bowl Okie. Oji looked down in disbelief. With the inner soles completely detached from the uppers, his feet were actually touching the ground. His beloved Air Maxes had just morphed into Fred Flintstone shoes.

Or this tearjerker about a “geriatric hoarder” in Buenos Aires who has a whole showroom full of DS/OGs:

All of these shoes were found in various states of decay in one of the biggest known cases of PU mass destruction. Seven minutes into the video, collector Robert Brooks pulls a forgotten artifact labeled Silver Wind from the stacks. He’s elated. It’s an obscure Adidas runner that’s eluded him for “a long, long time.” But as he lifts the shoe, the sole peels off and falls into the box. Recounting the story later, he sighs and whimpers “No!” stretching out the syllable for a few seconds, like a Loony Tunes character plunging from a high cliff into the abyss.

The polyurethane-injected foam soles common in a lot of sneakers tend to spontaneously fall apart after a while. Who knew? Certainly not the executive director of the Polyurethane Foam Association, who spoke with Wired about the problem and seemed shockingly out-of-the-loop: “I’ve never seen a technical paper on polyurethane shoes falling apart. But now that you mention it, I’ve owned several pairs of shoes that started cracking inside and outside. I didn’t know if they were just poorly made or if I stepped into something.”

Come on, man! Try reading this 2011 study on the aging performance of polyurethanes, which says that plastics like the one used in these sneakers are susceptible to hydrolysis and oxidation. Here’s a translation from Wired:

That’s right, the two things that make human life possible — water and air — are killing our shoes. Their role in degrading polyurethane can be attributed to the chemical processes of hydrolysis (in the presence of moisture) and oxidation (in the presence of oxygen). Simply put, the humidity in the air, and, yes, even the air itself, seeps into the PU and, slowly but surely, breaks it into itty-bitty sticky pieces. Delve deeper into the subject, and the news only gets worse. Bottom line: Pricy collectables shouldn’t be made out of PU.

But there’s good news! SonBinh T. Nguyen, a chemistry professor at Northwester University, (jokingly) told Wired that sneakerheads can preserve their treasures if they just keep them in an “airtight steel vessel filled with argon.”

Zing! But seriously, isn’t this disintegrating sneaker fiasco really just one big metaphor for the impending demise of our species? We built a society that’s cheap, fast, and flashy. Sustainable? Not so much. And now, climate change is the water and oxygen to our DS/OG Air Max 95s. But good news! If all else fails, we could all just go live in steel bunkers.

Scientists Are Arguing About When, Exactly, Humans Started to Rule the Planet

Mother Jones

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

Signs of human impact on the planet are everywhere. Sea levels are rising as ice at both poles melts; plastic waste clogs the ocean; urban sprawl paves over landscapes while industrial agricultural empties aquifers. Between climate change, urban development, and straight-up, old-school pollution, the Earth we inhabit now would be scarcely recognizable to our earliest ancestors 150,000 year ago.

In fact, these changes are so pronounced and their connection to human activity so obvious, that many scientists now believe we’ve already ventured well past a remarkable tipping point—Homo sapiens, they argue, have now surpassed nature as the dominant force shaping the Earth’s landscapes, atmosphere, and other living things. Units of deep geologic time often are defined by their dominant species: 400 million years ago fish owned the Devonian Period; 265 million years ago dinosaurs ruled the Mesozoic Era. Today, humans dominate the Anthropocene.

If defining what the Anthropocene represents is straight-forward, assigning it a commencement date has proved a monumental challenge. The term was first proposed by Russian geologist Aleksei Pavlov in 1922, and since then it has occupied off-and-on the attentions of the niche group of scientists whose job it is to decide how to slice our planet’s 4.5 billion-year history into manageable chunks. But in 2009, as climate change increasingly gained traction as a matter of public interest, the idea of actually making a formal designation started to appear in talks and papers. Today, if the scientific literature is any indication, the debate is fully ignited.

In fact, “it has been open season on the Anthropocene,” said Jan Zalasiewicz, a University of Leicester paleogeologist who is a leading voice in the debate. Within the last month a heap of new papers have come out with competing views on whether the Anthropocene is worthy of a formal designation, and if so, when exactly it began. The latest was published in Science today.
