Goodbye to all that.

“If half the animals died in London zoo next week it would be front page news,’ said Prof. Ken Norris, ZSL’s director of science. ‘But that is happening in the great outdoors. This damage is not inevitable but a consequence of the way we choose to live.'”

A sobering analysis by WWF and the Zoological Society of London finds that Earth has lost half(!) its wildlife over the past four decades (Those g*dd*mned parrotfish notwithstanding, of course.) “Creatures across land, rivers and the seas are being decimated as humans kill them for food in unsustainable numbers, while polluting or destroying their habitats…Today’s average global rate of consumption would need 1.5 planet Earths to sustain it. But four planets would be required to sustain US levels of consumption, or 2.5 Earths to match UK consumption levels.”

In related news, PriceWaterhouse runs the accelerating numbers on climate change and predicts a catastrophe within only twenty years, including “food security threats, coastal inundation, extreme weather events, ecosystem shifts, and widespread species extinction…at current rates, we’re headed towards 7.2 degrees Fahrenheit of warming by the end of the century—twice the agreed upon rate…G20 nations, for example, will need to cut their annual energy-related emissions by one-third by 2030, and by just over half by 2050.”

And here, the National Snow and Ice Data Center graphs the melting of the Arctic over the past 35 years. “The frigid dissolution, which the NSIDC calls ‘one of the most visible indicators of our changing climate,’ is worrying news as the ice plays a big role in reflecting solar radiation away from the planet. With less of it covering the ocean, the Northern Hemisphere will likely heat up quicker, hastening our arrival to the days of dangerously high sea levels.” And if — at this exceedingly late date — you don’t want to believe the science, ask the walruses.

It’s not like this all is a secret. We just saw the largest climate change march in history take place in New York. But you wouldn’t know about the threat we face from watching the news, who’ve (erroneously) decided that the real existential danger to life on this planet are ISIS (wrong) and Ebola (closer, still wrong.) Wolf Blitzer et al, you’re digging in the wrong place.

The Sun Has Come to Earth.

“The new figures for carbon dioxide were particularly surprising, showing the biggest year-over-year increase since detailed records were first compiled in the 1980s, Tarasova said in an interview. The jump of nearly three parts per million over 2012 levels was twice as large as the average increase in carbon levels in recent decades.”

We’re getting warmer: While the world focuses on deleting spam from U2, a new report finds carbon dioxide levels in the atmosphere accelerating ever faster. “‘The changes we’re seeing are really drastic,’ Tarasova said. ‘We are seeing the growth rate rising exponentially’…’It means we’re probably getting to the point where we’re looking at the ‘safe zone’ in the rearview mirror, even as we’re stepping on the gas.'”

Brick by Brick.

“These days the holy grail is an octopus or a dragon. I only know of three octopuses being found, and one was by me, in a cave in Challaborough, Devon. It’s quite competitive. If you heard that your neighbour had found a green dragon, you’d want to go out and find one yourself.”

By way of Dangerous Meta, BBC briefly looks into the Lego infestation of Cornwall. “[On February 13th, 1997] 62 containers were lost overboard about 20 miles off Land’s End – and one of them was filled with nearly 4.8m pieces of Lego, bound for New York…shortly after that some of those Lego pieces began washing up in both the north and south coasts of Cornwall. They’re still coming in today.”

The Very Air You Breathe.

“400 ppm was long considered a very serious measurement but it isn’t the end — it’s just a marker on the road to ever-increasing carbon pollution levels…’It is a milestone, marking the fact that humans have caused carbon dioxide concentrations to rise 120 ppm since pre-industrial times, with over 90 percent of that in the past century alone. We don’t know where the tipping points are.'”

Kepler 186f or bust? After flirting with 400ppm last May, carbon dioxide levels in the atmosphere reach 402 parts-per-million, the highest levels in at least 800,000 years. “When asked if the 400 ppm will be reached even earlier next year, Butler responded simply, “‘Yes. Every year going forward for a long time.'”

The End of All Things (Pt. 6).

“The worst mass extinction of all time came about 250 million years ago [the Permian-Triassic extinction event]. There’s a pretty good consensus there that this was caused by a huge volcanic event that went on for a long time and released a lot of carbon-dioxide into the atmosphere. That is pretty ominous considering that we are releasing a lot of CO2 into the atmosphere and people increasingly are drawing parallels between the two events.”

The WP’s Brad Plumer talks with Elizabeth Kolber about her new book, The Sixth Extinction, and the many grim portents for life on our planet these days. “I think many scientists would say that what we’re doing to the chemistry of the oceans is the most significant. One-third of the carbon-dioxide that we pump into the air ends up in the oceans almost right away, and when CO2 dissolves in water, it forms an acid, that’s just an unfortunate fact.”

Chasing Darkness.

“How dark it would have been—imagine leaning out your door and, on the darkest nights, not being able to see more than a few feet in any direction. Historian Peter Baldwin describes as ‘downright perilous’ the streets in early American cities, with few paved and then those only with cobblestones…What lights did exist were intended only as beacons or guides rather than to illuminate the night. The New York street lanterns burning whale oil were, in 1761, merely ‘yellow specks engulfed by darkness,’ and, even more than 100 years later, its gas lamps were still ‘faint as a row of invalid glow-worms.'”

In Slate, Paul Bogart describes (and laments) the end of night all across the world. “With at least 30 percent of all vertebrates and more than 60 percent of all invertebrates worldwide nocturnal, and with many of the rest crepuscular, [the] implications are enormous.”

The Arctic Depression.

“The release of methane from thawing permafrost beneath the East Siberian Sea, off northern Russia, alone comes with an average global price tag of $60 trillion in the absence of mitigating action — a figure comparable to the size of the world economy in 2012 (about $70 trillion). The total cost of Arctic change will be much higher.”

A new scientific analysis estimates the global cost of the melting Arctic, and it’s extremely terribad — $60 TRILLION bad. “Many experts now say that if recent trends continue and Arctic sea ice continues its ‘death spiral,’ we will see a ‘near ice-free Arctic in summer’ within a decade. That may well usher in a permanent change toward extreme, prolonged weather events ‘such as drought, flooding, cold spells and heat waves.'” So, hey, instead of working to address this multi-trillion dollar crisis before it hits, let’s just spend years and years and years sweating the deficit. Now, that’s leadership.

Update Per Mother Jones, the potentiality of such a methane bomb is in some dispute: “Bear in mind that there are many good reasons to be skeptical of a methane disaster — it is hardly a matter of scientific consensus that this is a real concern. And that stands in stark contrast to the issue of climate change in general, an issue on which scientists are overwhelmingly aligned (and where the solution remains incredibly obvious: cutting carbon emissions).”

400 (PPM) Blows.

“The news that CO2 is near 400 ppm for the first time highlights a question that scientists have been investigating using a variety of methods: when was the last time that CO2 levels were this high, and what was the climate like back then?…By drilling for ice cores and analyzing the air bubbles, scientists have found that, at no point during at least the past 800,000 years have atmospheric CO2 levels been as high as they are now.”

Carbon concentration in the atmosphere veers dangerously close to the dubious milestone of 400 part per million. (The revised reading came out at 399.89.) “For the previous 800,000 years, CO2 levels never exceeded 300 ppm, and there is no known geologic period in which rates of increase have been so sharp. The level was about 280 ppm at the advent of the Industrial Revolution in the 18th century, when the burning of fossil fuels began to soar.”

The Sun is Sinking Low.

“The amount of heat-trapping carbon dioxide in the air jumped dramatically in 2012, making it very unlikely that global warming can be limited to another 2 degrees Fahrenheit, as many global leaders have hoped, new federal figures show.”

Well, that’s that then. While Washington and our change president continue to fiddle, new data from 2012 suggests we are now flying past the two-degree rise threshold we set for ourselves to alert a global calamity due to climate change. “‘The prospects of keeping climate change below that (2-degree goal) are fading away,’ Tans says.”

For what this means, see Bill McKibben in the article I linked here and here:

Some context: So far, we’ve raised the average temperature of the planet just under 0.8 degrees Celsius, and that has caused far more damage than most scientists expected. (A third of summer sea ice in the Arctic is gone, the oceans are 30 percent more acidic, and since warm air holds more water vapor than cold, the atmosphere over the oceans is a shocking five percent wetter, loading the dice for devastating floods.)

Given those impacts, in fact, many scientists have come to think that two degrees is far too lenient a target. “Any number much above one degree involves a gamble,” writes Kerry Emanuel of MIT, a leading authority on hurricanes, “and the odds become less and less favorable as the temperature goes up.” Thomas Lovejoy, once the World Bank’s chief biodiversity adviser, puts it like this: “If we’re seeing what we’re seeing today at 0.8 degrees Celsius, two degrees is simply too much.” NASA scientist James Hansen, the planet’s most prominent climatologist, is even blunter: “The target that has been talked about in international negotiations for two degrees of warming is actually a prescription for long-term disaster.”

At the Copenhagen summit, a spokesman for small island nations warned that many would not survive a two-degree rise: “Some countries will flat-out disappear.” When delegates from developing nations were warned that two degrees would represent a “suicide pact” for drought-stricken Africa, many of them started chanting, “One degree, one Africa.”

And that’s two degrees. Now, try four. In other words, game over, Man, game over.

Update: More fuel for the pyre: The Earth’s temperature graphed over 10,000 years. “‘What we found is that temperatures increased in the last hundred years as much as they had cooled in the last six or seven thousand,’ he said. ‘In other words, the rate of change is much greater than anything we’ve seen in the whole Holocene,” referring to the current geologic time period, which began around 11,500 years ago.'”

So Hot in Herre.

“This video, put together by NASA using temperature records from 1880 to 2011, shows you the warming world in just 26 terrifying seconds. Blue shows temperatures that are lower than the baseline average between 1951 and 1980, and reds show temperatures above the average.” By way of Mother Jones, a NASA animation tracks the warming of the earth over the past century and change. A crazy coincidence, I know.

In related news and per this post, a high-school friend sends along these similarly distressing charts of arctic ice melt. And here, via The Guardian, are the 100 most endangered species on the planet. “Some of the creatures on the list are down to the last few individuals. For example, numbers of the saola – an antelope known as the Asian unicorn, so rarely is it sighted – have been whittled down to the last few tens in existence.“
