26 August 2015, The Guardian, US environmental agency advising Australia on impact of fracking on water. The US’s Environmental Protection Agency has given Australia’s Department of the Environment details of recent fracking study and is peer reviewing papers. The Australian government has obtained information from US environmental regulators on the impact of fracking upon water supplies to help inform a new set of guidelines it is preparing on the controversial activity. The US’s Environmental Protection Agency has supplied the Australian Department of the Environment with the details of a recent study on fracking. The EPA has also helped the department peer review a number of its own documents. The EPA report is the result of a request from Congress to analyse how fracking for oil and gas is affecting water supplies in the US. Fracking, or hydraulic fracturing, is a process where a combination of water, chemicals and sand is injected deep underground in order to release oil or gas from rocky areas. Fracking is banned in Victoria and has faced opposition from environmental groups, some farmers and radio personality Alan Jones in New South Wales and Queensland. However, the EPA report said it could find no evidence of “widespread, systemic impacts on drinking water resources in the United States” from fracking, which is deployed across vast swathes of the country. Read More here

26 August 2015, The Carbon Brief, Celebrating soils: Why are they so important for our climate? From the 800th anniversary of the Magna Cartato the 60th birthday of the Birds Eye Fish Finger, there are plenty of reasons to mark 2015 as an important year. But you could be forgiven for being unaware that 2015 is also theUN International Year of Soils. By putting soils centre stage, the UN Food and Agricultural Organisation (FAO) aims to raise awareness of how important soils are for producing food and fuel, and keeping ecosystems healthy. But soils have also been thrust to the forefront of international science because of climate change. Globally, the top metre of soils contains about three times as much carbon as in our entire atmosphere. Losing carbon from the soil into the atmosphere can add to climate warming. But if soils can be managed in a way that means they store more carbon, they can help to reduce the amount of carbon in the atmosphere, and thereby help limit climate change. Read More here

26 August 2015, Climate News Network, Solar power takes giant strides as prices fall. Massive solar power stations are being built in the world’s “sun belts” − with the US and India competing to have the largest in the world. The US Navy is investing in what will be the largest solar farm in the world in order to provide power for 14 of its bases. The climate of Arizona, where the two earlier phases of the Mesquite solar farm are already up and running, provides 300 days of sunshine a year. And the Navy’s deal to extend the farm is the largest purchase of renewable energy ever made by a US federal government agency. The solar farm project is one of a growing number being installed across what is known as the American Sun Belt − the southern states of America, which have expanding populations, plenty of sunshine, but also large areas of arid and unproductive land. The price of solar panels has now fallen so far worldwide that, in sunny climes, they can compete on cost with any other form of energy generation. This new generation of huge solar farms produces as much power as a large coal-fired plant. Read More here

26 August 2015, NASA The fingerprints of sea level rise. When you fill a sink, the water rises at the same rate to the same height in every corner. That’s not the way it works with our rising seas. According to the 23-year record of satellite data from NASA and its partners, the sea level is rising a few millimeters a year — a fraction of an inch. If you live on the U.S. East Coast, though, your sea level is rising two or three times faster than average. If you live in Scandinavia, it’s falling. Residents of China’s Yellow River delta are swamped by sea level rise of more than nine inches (25 centimeters) a year. These regional differences in sea level change will become even more apparent in the future, as ice sheets melt. For instance, when the Amundsen Sea sector of the West Antarctic Ice Sheet is totally gone, the average global sea level will rise four feet. But the East Coast of the United States will see an additional 14 to 15 inches above that average. Read More here
