Geoengineering should not be used as a climate fix yet, says US science academy

Guardian: Climate change has advanced so rapidly that the time has come to look at options for a planetary-scale intervention, the National Academy of Science said on Tuesday. But it was categorical that such ‘geoengineering’ should not currently be deployed at scale or considered as an alternative to cutting emissions now. The much-anticipated report from the country’s top scientists strongly endorsed the idea of further research into a topic it admitted had once been taboo: proposed high-tech fixes for...

US harvest threatened by water-intensive oil and gas boom

Guardian: The recent World Economic Forum Global Risks report identifies the 10 “biggest threats to the stability of the world” over the next 10 years. These are difficult times, and the catalogue of potential threats includes many that may seem familiar, including high unemployment, war and the spread of infectious disease. It is particularly telling, therefore, given the dangers confronting us, that the report points to water crises as one of the top global risks. Related: Political will is the biggest...

Inventive water harvesting helps Kenya balance rain extremes

Reuters: Samuel Lontogunye has long weathered regular shortages of water and food. But he believes a recent addition to his drought-prone village could change that: a water harvesting plant. Lontogunye, 69, and other members of his community on the fringes of Kenya's Rift Valley have built a weir at the nearby Ngeng' river to capture and store water which would otherwise drain away during periods of heavy rainfall. The weir, a concrete barrier that stretches across the river, allows water to pool behind...

Catastrophic flooding is getting worse and we’re woefully unprepared

Mother Jones: The Midwest is no stranger to devastating floods. Last summer, the region was inundated with two month's worth of rainfall in just one week, submerging farms and killing crops. Torrential downpours following a drought in Illinois in 2013 led to flooding that cost $1 billion. And Midwest flooding in 2008 caused 24 deaths and $15 billion in losses. Across the country, the United States has suffered from more than $260 billion in flood-related damages between 1980 and 2013--it's the most common natural...

Forest fires may resurrect radioactive soil near Chernobyl

United Press International: When the Chernobyl Nuclear Power Plant exploded in 1986, some 85 petabecquerels of radioactive cesium was released into the atmosphere and surrounding environs. Researchers believe somewhere between 2 and 8 PBq is still lingering in the soil and forest debris that surrounds the disaster site. Scientists have long feared that forest fires could send leftover radiation back into the atmosphere as radioactive leaves and other dead and dry plant material burn up -- traces of cesium wafting skyward...

Australia scorching 2013 heat record was ‘virtually impossible’ without global warming

Washington Post: Afterwards — after the blistering heat and the bushfires – they would call it the “Angry Summer.” But whatever the description, the Australian summer of 2012-2013 provided a terrifying preview of a world under climate change. According to the country’s Bureau of Meteorology, a devastating heat wave in late 2012-early 2013 saw “records set in every State and Territory … the nationally averaged daily temperature rose to levels never previously observed, and did this for an extended period.” What...

A biofuel debate: Will cutting trees cut carbon?

New York Times: Does combating climate change require burning the world’s forests and crops for fuel? It certainly looks that way, judging from the aggressive mandates governments across the globe have set to incorporate bioenergy into their transportation fuels in the hope of limiting the world’s overwhelming dependence on gasoline and diesel to move people and goods. While biofuels account for only about 2.5 percent today, the European Union expects renewable energy — mostly biofuels — to account for 10 percent...

China slates environment ministry after graft probe

Reuters: China's main anti-graft body reprimanded the environment ministry on Tuesday for a series of problems, including interference by ministry officials and their relatives in environmental impact assessments. Environmental degradation is one of China's most serious issues and a very sensitive one too, with thousands of protests every year sparked by concern about pollution, particularly from factories. Polluting plants like chemical factories and oil refineries are supposed to undergo strict environmental...
