4 February 2016 Global Footprint newsletter article , If an acre of forest burns up in flames, what’s the cost? Zero, was FEMA’s reply in 2013. The Federal Emergency Management Agency rejected California’s request for a federal “major disaster” declaration and funding after the devastating Rim Fire, because it only knew how to put a price tag on man-made structures. The 400 square miles of forests that had been reduced to ashes and charred stumps—including part of Yosemite National Park—couldn’t translate into dollar amounts.How times have changed. Two weeks ago, the state of California was named one of the 13 winners of the National Disaster Resilience Competition by the U.S. Department of Housing and Urban Development (HUD) and the Rockefeller Foundation. California won more than $70 million to help fund several disaster preparedness projects in communities affected by the Rim Fire. What happened? As extreme weather events have become more frequent due to climate change, decision-makers are realizing that conventional project assessments won’t do, and that building strong, resilient communities requires drastically innovative approaches. In a first for a federal agency, the HUD Office of Economic Resilience, in collaboration with the Rockefeller Foundation, mandated that nature be a key element in the design of development projects submitted to the $1 billion competition. HUD required all applicants to use a more complete benefit-cost analysis developed by Earth Economics, a close partner of Global Footprint Network. It is exactly the kind of approach that Global Footprint Network and Earth Economics called for in July in our State of the States Report, which found the United States demands twice the resources that its ecosystems can regenerate. It is also similar to the approach that Global Footprint Network piloted with the state of Maryland when developing our Net Present Value Plus tool. Read more here

28 January 2016, Climate Home, Scientists pour cold water on ocean geoengineering idea. One keenly-argued possible way of moderating the build-up of carbon dioxide in the atmosphere may not work, scientists have concluded. They say there is evidence that seeding the oceans with iron so that the algae that live there will multiply and devour more CO2 − thus preventing it reaching the atmosphere and intensifying the human contribution to global warming – is not as promising a solution as its supporters hope. The extra iron can certainly stimulate the algae to grow more vigorously, but at a cost. More algae in one part of the oceans may mean there will be fewer in other areas, the researchers say. Report: Scientists warn against geoengineering as short-term climate fix. They report in Nature journal that the depths of the central Pacific Ocean contain ancient sediments that cast doubt on iron’s ability to slow the Earth’s steady temperature rise. In parts of the oceans that lack the iron that plants need, algae are scarce. Experiments have shown that dumping iron into these areas can encourage algal growth, so large-scale fertilisation could theoretically reduce atmospheric CO2. The seafloor sediments the team studied show that, during past ice ages, more iron-rich dust blew from cold and barren landmasses into the oceans, apparently producing more algae in these areas and, presumably, a creating natural cooling effect. But the researchers say increased algal growth in one area can inhibit growth elsewhere, because ocean waters are always on the move and algae also need other nutrients, such as nitrates and phosphates.

22 January 2016, Climate News Network, Plutonium’s global problems are piling up. Increasing worldwide stockpiles of surplus plutonium are becoming a political embarrassment, a worrying security risk, and a hidden extra cost to the nuclear industry. Two armed ships set off from the northwest of England this week to sail round the world to Japan on a secretive and controversial mission to collect a consignment of plutonium and transport it to the US. The cargo of plutonium, once the most sought-after and valuable substance in the world, is one of a number of ever-growing stockpiles that are becoming an increasing financial and security embarrassment to the countries that own them. So far, there is no commercially viable use for this toxic metal, and there is increasing fear that plutonium could fall into the hands of terrorists, or that governments could be tempted to use it to join the nuclear arms race. All the plans to use plutonium for peaceful purposes in fast breeder and commercial reactors have so far failed to keep pace with the amounts of this highly-dangerous radioactive metal being produced by the countries that run nuclear power stations. The small amounts of plutonium that have been used in conventional and fast breeder reactors have produced very little electricity − at startlingly high costs. Read More here
9 January 2016, Climate News Network, Ice melt speeds up sea level rise. Scientists have found evidence suggesting that melting icecap water from the interior of Greenland is adding to sea level rise faster than previously realised. Water may be flowing from the Greenland icecapand into the sea more quickly than anybody expected. It doesn’t mean that global warming has got conspicuously worse: rather, researchers have had to revise their understanding of the intricate physiology of the northern hemisphere’s biggest icecap. There is enough ice and snow packed deep over 1.7 million square kilometres of Greenland that, were it all to melt, would cause a rise in global sea levels of about six metres. Climate calculations Since the icecap is melting as the atmospheric levels of the greenhouse gas carbon dioxide rise, and global temperatures rise with them, as a consequence of the human combustion of fossil fuels, the rate at which summer meltwater gets into the oceans becomes vital to climate calculations. The latest rethink begins not with the pools of water that collect on the surface each summer, or the acceleration of the glaciers as they make their way to the ocean, but with a granular layer of snow just below the surface, called firn. This is old snow in the process of being compacted into glacier ice, and covers the island in a layer up to 80 metres thick. Until now, researchers have understood this firn layer as a kind of sponge that absorbs meltwater and holds it, thus limiting the flow of melting ice into the sea. Read More here
