10 March 2016, Washington Post: Atmospheric carbon dioxide concentrations have spiked more in the period from February 2015 to February 2016 than in any other comparable period dating back to 1959, according to a scientist with the National Oceanic and Atmospheric Administration’s Earth System Research Laboratory. The change in average concentrations from February of last year to February of this year was 3.76 parts per million at the storied Mauna Loa Observatory in Hawaii, leaving the concentration at 404.02 parts per million for February, based on preliminary data. Pieter Tans, lead scientist of NOAA’s Global Greenhouse Gas Reference Network, confirmed that the increase, reported previously by New Scientist, represented a record year-over-year growth for Mauna Loa. He also said that in addition to the stark rise in carbon dioxide levels over the past year, researchers have now observed four straight years of increases of more than 2 parts per million in the atmosphere. “We’ve never seen that,” Tans said. “That’s unprecedented.” Read More here

10 March 2016, Science Daily, Cutting cattle carbon: Bad breath and flatulence. Cattle have bad breath and commonly suffer from severe, chronic flatus generating large amounts of methane, which is a greenhouse gas and a driver of anthropogenic global warming. There is an obvious answer to this problem, stop breeding cattle. Unfortunately a large proportion of us enjoy our bovine dairy products and meat too much. Until synthetic products that are indistinguishable from the real thing become available and accepted by milk drinkers and steak fans, we will have to look into alternative approaches to reducing the carbon emissions from these creatures. Writing in International Journal of Global Warming, Abdelmajid Moumen, Ghizlane Azizi, Kaoutar Ben Chekroun and Mourad Baghour of the Université Mohamed 1er, in Nador, Morocco, have reviewed the various approaches to reducing methane emissions from cattle and other livestock. These approaches involve improved genetic selection through breeding, modification of dietary composition, or through rumen microbial manipulation, vaccines against the methanogenic bacteria that generate the methane in these animals and various other techniques. It is possible that among the approaches or with a combination of approaches there might be a way to reduce the global burden of methane emissions from livestock. Read More here
8 March 2016, Energy Post, New data debunks clean energy claims Apple, Amazon, Google. Recent claims by owners of large data centers that a large part of their operations are powered by renewable energy have skeptics coming out of from under their solar panels. Now, there is hard data proving that skepticism is valid, writes energy consultant and author Jim Pierobon. He applauds the efforts of companies like Amazon, Apple and Google to strive for clean energy, but calls for more transparency on their actual practices. A recent report by Lux Research casts a large shadow on some data centers’ clean-energy claims. Scientists at Lux Research found the data centers frequently draw on far more coal-fired power with its much higher emissions than renewables. Companies such as Google, Amazon and Apple should be careful about the claims they make, lest they come across partly as PR stunts. Amazon’s claims are off-base in 23 of its data centers in Virginia. It is less than transparent about how it calculates its emissions “They aren’t doing as much as they claim about sourcing their electricity,” said Ory Zik, Lux Vice President of Analytics. Full-time Data centers need a lot of power to run 24/7. They cannot rely on the intermittent supplies that come from solar and wind energy systems. As a result, they must draw electricity from the regional power grid. Solar and wind systems they have deployed or are developing can help supply renewable power to their centers and to power grids. But they supply nowhere near enough electricity on their own to run operate data centers reliably full-time. Read More here
8 March 2016, Renew Economy, Government somnolence on climate change health costs. Climate change is described by leaders of the medical profession as the greatest health risk of this century. Its health impacts are already significant both internationally and in Australia and are predicted to increase with rising temperatures. The severity of natural disasters from extreme weather events is increased by climate change and is an important cause of harms to our health. A report prepared for the Australian Roundtable by Deloitte Access Economics on the costs of these disasters is remarkable in exposing the health costs. It requires dedicated government attention and action if many Australians are to be spared unnecessary harm and suffering. In 2015 the social costs of natural disasters were at least equal to the physical costs in a total of over $9 billion — about 0.6% of gross domestic product. The total cost of disasters is expected to rise to an average of $33 billion per year in real terms by 2050 unless steps are taken to increase resilience and address mitigation. However, as the report indicates, these costs are calculated without considering the potential impact of climate change. This report “assumes natural hazards will be as frequent in the future as in the past. Given the evidence for climate change, this is unlikely to be the case – extreme weather events will probably occur more regularly in the future than in the past” It is not difficult to calculate the tangible costs of disasters, the damage to infrastructure of buildings, roads, land and crops but the importance of the new Report lies in its costing of the intangible damage to people, the health and well being of the affected community-the lives destroyed from an increase in mental health issues, family violence, alcohol consumption, chronic and non-communicable diseases and short-term unemployment.
