Crazy maths makes nonsense of Irish climate change policy
'John FitzGerald on madness of Ireland burning peat for electricity:

'the current subsidy per job involved is at least €100,000 a year. The Bord na Móna annual report indicates that, in the year 2016/2017, its workers’ average pay was €50,000. In other words, the subsidy per job is around twice what the workers involved actually earn.

If the peat-fired power stations were closed tomorrow, and the workers involved continued to be employed on their current wages, subsidising these jobs would only cost €50 million, not €100 million. Electricity consumers would pay less to subsidise these jobs, and Ireland’s greenhouse gas emissions would fall substantially as a result of discontinuing this polluting fuel use.'

We should plan for closure by 2020 of peat-fired electricity generation:

–greatly benefit environment;
–save electricity consumers money;
–protect livelihoods.

Bitcoin’s energy use got studied, and you libertarian nerds look even worse than usual | Grist
This is awful. What a waste:
Bitcoin’s energy footprint has more than doubled since Grist first wrote about it six months ago.

It’s expected to double again by the end of the year, according to a new peer-reviewed study out Wednesday. And if that happens, bitcoin would be gobbling up 0.5 percent of the world’s electricity, about as much as the Netherlands.

That’s a troubling trajectory, especially for a world that should be working overtime to root out energy waste and fight climate change. By late next year, bitcoin could be consuming more electricity than all the world’s solar panels currently produce — about 1.8 percent of global electricity, according to a simple extrapolation of the study’s predictions. That would effectively erase decades of progress on renewable energy.

Ireland's staggering hypocrisy on climate change | Environment | The Guardian
The national climate policy is a greenwash – the country is certain to miss its 2020 emissions target and still handing out drilling licences

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.

March 2016's shocking global warming temperature record
Keep in mind that it took from the dawn of the industrial age until last October to reach the first 1.0 degree Celsius, and we’ve come as much as an extra 0.4 degrees further in just the last five months. Even accounting for the margin of error associated with these preliminary datasets, that means it’s virtually certain that February handily beat the record set just last month for the most anomalously warm month ever recorded. That’s stunning.


eek.
