Biologists Say Half the World's Species Could Be Extinct By End of Century

One in five species on Earth now faces extinction, and that will rise to 50% by the end of the century unless urgent action is taken. That is the stark view of the world’s leading biologists, ecologists and economists who will gather on Monday to determine the social and economic changes needed to save the planet’s biosphere. “The living fabric of the world is slipping through our fingers without our showing much sign of caring,” say the organisers of the  Biological Extinction conference held at the Vatican this week. - The Guardian

Proposed Trump Budget Would Hike Defense Budget, Cut EPA

Millions Without Water in Chile Capital After Floods

New Jersey Lowers Childhood Blood Lead Level Benchmark to Increase Early Intervention

Lead screening and treatment requirements for New Jersey children are about to get tighter as the state establishes stricter guidelines to better care for those at risk. New Jersey adopted the most up-to-date benchmark from the federal Centers of Disease Control and Prevention to determine when and how a child should be treated for elevated levels of lead in their blood. Health experts said research now finds that even low levels can lead to developmental problems. - Press of Atlantic City

Coal Industry Casts Itself As Clean Energy Player

President Trump has questioned the science behind climate change as “a hoax” in positioning himself as a champion of coal. The three largest American coal producers are taking a different tack. Seeking to shore up their struggling industry, the coal producers are voicing greater concern about greenhouse gas emissions. Their goal is to frame a new image for coal as a contributor, not an obstacle, to a clean-energy future — an image intended to foster their legislative agenda. - New York Times

Trump's likely science adviser calls climate scientists 'glassy-eyed cult'

The man tipped as frontrunner for the role of science adviser to Donald Trumphas described climate scientists as “a glassy-eyed cult” in the throes of a form of collective madness. William Happer, an eminent physicist at Princeton University, met with Trump last month to discuss the post and says that if he were offered the job he would take it. Happer is highly regarded in the academic community, but many would view his appointment as a further blow to the prospects of concerted international action on climate change. - The Guardian

Oroville Is a Warning for California Dams, As Climate Change Adds Stress

The threat of catastrophic flooding from the damaged Oroville Dam in Northern California this week — forcing the evacuation of nearly 200,000 people because of what environmental groups had asserted in 2005 was a design flaw — presented a warning sign for California, where a network of dams and waterways is suffering from age and stress. It also demonstrated that older dams may not be designed to deal with the severe weather patterns California has experienced because of global warming. - New York Times

Clean Energy Grows Globally, But Many of World's Poorest Are Left In the Dark

Energy access, efficiency and renewables are on the rise in many developing nations, but in places like Sub-Saharan Africa, the energy situation is still grim and hundreds of millions remain unconnected, according to a new World Bank report.  - The Daily Climate

Trump Signs Law Rolling Back Disclosure Rules For Energy and Mining Companies

President Trump signed his first piece of legislation on Tuesday, a measure that could presage the most aggressive assault on government regulations since President Reagan. The bill cancels out a Securities and Exchange Commission regulation that would have required oil and gas and mining companies to disclose in detail the payments they make to foreign governments in a bid to boost transparency in resource-rich countries. It is the first of a series of bills Congress is considering that would take advantage of the Congressional Review Act of 1996, which had been used only once before today. - Washington Post
