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.

Malicious Lifestyle Apps Found On Google Play, 30 Million Installs Recorded

A total of 50 malicious apps have managed to bypass Google's security checks and land on the Google Play store, leading to millions of installs on Android devices. ZDNet reports: Now, the cybersecurity team from Avast have found a further 50 apps relating to lifestyle services which masquerade as legitimate software but are actually adware, and these malicious apps have been downloaded a total of 30 million times. On Tuesday, Avast published a report on the discovery, in which the apps are linked to each other through third-party libraries that "bypass the background service restrictions present in newer Android versions." "Although the bypassing itself is not explicitly forbidden on the Play Store, Avast detects it as Android:Agent-SEB [PUP], because apps using these libraries waste the user's battery and make the device slower," the researchers say. "The applications use the libraries to continuously display more and more ads to the user, going against Play Store rules." Each app displays full-blown ads to users, and in some cases, will also attempt to lure viewers to install additional adware-laden applications. The malicious apps include Pro Piczoo, Photo Blur Studio, Mov-tracker, Magic Cut Out, and Pro Photo Eraser. Installation rates range from one million to one thousand.

Municipalities open their GIS systems to citizens

Many public administrations already use open source Geographic Information Systems (GIS) to let citizens look at public geographic data trough dedicated Web sites. Others use the same software to partially open the data gathering process: they let citizens directly add geographic information to the official, high-quality GIS databases by drawing or clicking on digital maps.
