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.

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.”
