Burning Fossil Fuels Almost Ended All Life on Earth - The Atlantic
“what I like to talk about is ‘the Great Weirding’ and not just the Great Dying because the Great Dying seems to have been a relatively quick event at the very end. But if you just talk about the Great Dying you’re missing all of this other crazy stuff that led up to it,” he said. “The Earth was getting really weird in the Permian. So we’re getting these huge lakes with these negative pHs, which is really weird, we don’t know why that happened. Another thing is that the whole world turned red. Everything got red. You walk around today and you’re like, ‘Hey, there’s a red bed, I bet it’s Permian or Triassic.’ The planet started looking like Mars. So that’s really weird. We don’t know why it turned red. Then you have a supercontinent, which is weird in the first place. Plate tectonics has to be acting strangely when you have all the continents together. Eventually it rifts apart and we go back into normal plate tectonics mode, but during the Permian-Triassic everything’s jammed together. So there has to be something strange going on. And then at the end, the Earth opens up and there’s all these volcanoes. But we’re not talking about normal volcanoes, we’re talking about weird volcanoes.”

When Will Climate Change Make the Earth Too Hot For Humans?
The Earth has experienced five mass extinctions before the one we are living through now, each so complete a slate-wiping of the evolutionary record it functioned as a resetting of the planetary clock, and many climate scientists will tell you they are the best analog for the ecological future we are diving headlong into. Unless you are a teenager, you probably read in your high-school textbooks that these extinctions were the result of asteroids. In fact, all but the one that killed the dinosaurs were caused by climate change produced by greenhouse gas. The most notorious was 252 million years ago; it began when carbon warmed the planet by five degrees, accelerated when that warming triggered the release of methane in the Arctic, and ended with 97 percent of all life on Earth dead. We are currently adding carbon to the atmosphere at a considerably faster rate; by most estimates, at least ten times faster.

TIL we have more gravity than Canada
'Early gravity mapping efforts in the 1960s revealed that the Hudson Bay area in particular exerts a weaker gravitational force. Since less mass equals less gravity, there must be less mass underneath these areas.' informed!

Forecast Blog
Forecast.io are doing such a great job of applying modern machine-learning to traditional weather data. "Quicksilver" is their neural-net-adjusted global temperature geodata, and here's how it's built

Rectangular subdivisions of the world
'Eric Fischer, who continues his string of mapping fun and doesn't even do it for his day job, maps the world in binary subdivisions. Each bounding box contains an equal number of geotagged tweets.' via Nelson
