Melting Permafrost In Arctic Will Have $70 Trillion Climate Impact, Study Says

An anonymous reader quotes a report from The Guardian: The release of methane and carbon dioxide from thawing permafrost will accelerate global warming and add up to $70 trillion to the world’s climate bill, according to the most advanced study yet of the economic consequences of a melting Arctic. If countries fail to improve on their Paris agreement commitments, this feedback mechanism, combined with a loss of heat-deflecting white ice, will cause a near 5% amplification of global warming and its associated costs, says the paper, which was published on Tuesday in Nature Communications.

The authors say their study is the first to calculate the economic impact of permafrost melt and reduced albedo — a measure of how much light that hits a surface is reflected without being absorbed — based on the most advanced computer models of what is likely to happen in the Arctic as temperatures rise. It shows how destabilized natural systems will worsen the problem caused by man-made emissions, making it more difficult and expensive to solve. They assessed known stocks of frozen organic matter in the ground up to 3 meters deep at multiple points across the Arctic. These were run through the world’s most advanced simulation software in the US and at the UK Met Office to predict how much gas will be released at different levels of warming. Even with supercomputers, the number crunching took weeks because the vast geography and complex climate interactions of the Arctic throw up multiple variables. The researchers then applied previous economic impact models to assess the likely costs. Permafrost melt is the main concern because of all the carbon trapped in the frozen ground. “On the current trajectory of at least 3C of warming by the end of the century, melting permafrost is expected to discharge up to 280 gigatons of carbon dioxide and 3 gigatons of methane, which has a climate effect that is 10 to 20 times stronger than CO2,” the report says. “This would increase the global climate-driven impacts by by $70 trillion between now and 2300. This is 10 times higher than the projected benefits from a melting Arctic, such as easier navigation for ships and access to minerals, says the paper.”

ICANN Proposes Allowing Unlimited Fee Increases For .Org Domain Names

GeorgeK writes: ICANN is proposing allowing unlimited fee increases for .org domain names, which currently are allowed to increase a maximum of 10% annually. That 10% annual cap on fee increases came about after the huge public outcry that ensued in 2006 when a comparable proposal to eliminate price caps was made, and successfully opposed by the public. It seems that ICANN did not learn from history.
Nat Cohen explains why the new proposal to eliminate price caps is a bad idea. Similar proposals exist for the .info, .biz, and .asia top-level domains, and are all open for public comment now (.org public comment period ends April 29, 2019). If these unlimited fee increases are permitted, it is likely that Verisign will seek to further increase their fees for .com and .net. I encourage readers who wish to oppose these unlimited fee increases to submit comments today.

Making Microfluidics Simpler With Shrinky Dinks

It’s as if the go-to analogy these days for anything technical is, “It’s like a series of tubes.” Explanations thus based work better for some things than others, and even when the comparison is apt from a physics standpoint it often breaks down in the details. With microfluidics, the analogy is perfect because it literally is a series of tubes, which properly arranged and filled with liquids or gasses can perform some of the same control functions that electronics can, and some that it can’t.

But exploring microfluidics can be tough, what with the need to machine tiny passages for fluids to flow. Luckily, [Justin] has turned the process into child’s play with these microfluidic elements made from Shrinky Dinks. For those unfamiliar with this product, which was advertised incessantly on Saturday morning cartoon shows, Shrinky Dinks are just sheets of polystyrene film that can be decorated with markers. When placed in a low oven, the film shrinks about three times in length and width while expanding to about nine times its pre-shrunk thickness. [Justin] capitalized on this by CNC machining fine grooves into the film which become deeper after shrinking. Microfluidics circuits can be built up from multiple layers. The video below shows a mixer and a simple cell sorter, as well as a Tesla valve, which is a little like a diode.

We find [Justin]’s Shrinky Dink microfluidics intriguing and can’t wait to see what kind of useful devices he comes up with. He’s got a lot going on, though, from spider-powered beer to desktop radio telescopes. And we wonder how this technique might help with his CNC-machined microstrip bandpass filters.
