Earth's most remote continent finally caught up with its more populated counterparts. “Carbon dioxide has been steadily rising since the start of the Industrial Revolution, setting a new high year after year,” writes Brian Kahn at Climate Central
. “There’s a notable new entry to the record books. The last station on Earth without a 400 parts per million (ppm) reading has reached it.”
In the remote reaches of Antarctica, the South Pole Observatory carbon dioxide observing station cleared 400 ppm on May 23, according to an announcement from the National Oceanic and Atmospheric Administration on Wednesday. That’s the first time it’s passed that level in 4 million years (no, that’s not a typo).
The South Pole Observatory in Antarctica could see carbon dioxide readings fall below 400 ppm again, but new research published earlier this week shows that the planet as a whole has likely crossed the 400 ppm threshold permanently--at least, for our lifetimes.
“The increase of carbon dioxide is everywhere, even as far away as you can get from civilization,” Pieter Tans, a carbon-monitoring scientist at the Environmental Science Research Laboratory, told Climate Central. “If you emit carbon dioxide in New York, some fraction of it will be in the South Pole next year.”

A better understanding how a sperm swims its way toward an egg could help inform new treatments for male infertility. Researchers from the University of York have now come up with a mathematical formula to model how large numbers of moving sperm interact with fluid they’re swimming through. From the University: By analysing the head […]
Dr Gale Ridge is a public entomologist at the Connecticut Agricultural Experiment Station, where an average of 23 people a day call, write or visit; an increasing proportion of them aren’t inquiring about actual insects, they’re suffering from delusional parasitosis, and they’re desperate and even suicidal.
Biologist Nipam Patel and his team at UC Berkeley study how butterflies develop wing shape and color by performing surgery on caterpillars, creating translucent windows in their cocoons.
The Raspberry Pi Foundation has done outstanding work packing a fully capable desktop computer into a package the size of a deck cards—especially one that only costs $35. But if you already have a working laptop, why should you care? Oh, how much you have to learn. Besides operating well as a compact digital media hub, […]
Custom coffee vessels are the perfect piece of office flair, but it’s just a matter of time before your VOTE FOR PEDRO mug will start to lose its relevant wit. Why not have a new one every day, with whatever silly nonsense you want sticking off the sides? You can save big on your novelty […]
The Lightning port has thus far resisted the cruel fate that befell the headphone jack, and despite rumors that it may be disappearing come iPhone 8, for the present and foreseeable future, Lightning cables are a hot commodity for iPhone users. As such, we must make do in this strange time in which long, glorified […]
