Climate Change

"Companies that disclose greenhouse gas emissions see a small rise in stock price following disclosure, compared to similar companies that keep mum, researchers say."

"A team of Louisiana scientists is laying the groundwork for creating a new carbon storage industry that could both reduce the effects of global warming and rebuild wetlands along the state’s coastline. Sarah Mack, founder of New Orleans-based Tierra Resources, and Louisiana State University wetlands scientists John W. Day and Robert Lane have come up with a method for measuring the molecules of carbon removed from the atmosphere by the soils and plants that are created with coastal restoration projects."

"California approved aggressive new rules on Friday to reduce greenhouse gas emissions by requiring automakers to put many more electric and hybrid vehicles on the Golden State's roads by 2025. The regulations were approved unanimously by nine members of the state's powerful air-quality regulator, the California Air Resources Board, at a meeting in Los Angeles."

"They are expected to cut greenhouse gas emissions by 34 percent and smog and soot pollutants by 75 percent by 2025, in part by putting 1.4 million electric, plug-in and hydrogen vehicles on the state's roads.

"The US Department of Agriculture (USDA) released a long overdue new version of their Plant Hardiness Zone Map yesterday—the first update since 1990."

"How out of date was the 1990 map? It was based on data from 1974 to 1986. That's 26 years ago.

The new map is interactive, which is cool, and based on a much finer data scale than the old one, which is great. And guess what. It shows that things are getting warmer. The USDA managed to pretty much bury that fact in Bureaucratese in their press release ... ."

"In a move that could reshape the American automobile industry, California regulators Thursday are expected to approve sweeping new rules requiring that 15 percent of new cars sold in California by 2025 run on electricity, hydrogen or other systems producing little or no smog."

"The regulations by the California Air Resources Board, dubbed the 'advanced clean car rules,' would start in 2018, ramping up each year and ultimately resulting in 1.4 million 'zero emission' vehicles on California roads by 2025. Today there are only about 10,000 such vehicles in the state. ...

"UXBRIDGE, Canada -- Hundreds of thousands of shale gas wells are being "fracked" in the United States and Canada, allowing large amounts of methane, a highly potent greenhouse gas, to escape into the atmosphere, new studies have shown. Shale gas production results in 40 to 60 percent more global warming emissions than conventional gas, said Robert Howarth of Cornell University in New York State."

"For years, climate scientists have been assailed from many sides -- through e-mail hacking, death threats, politician’s demands for documents, Freedom of Information requests (many having the strong smell of a fishing expedition). A Climate Science Legal Defense Fund set up last fall has taken on a formal affiliation with Public Employees for Environmental Responsibility, an established nonprofit group offering aid and advice to government whistleblowers and scientists working on environmental issues."

"Mexico’s Laguna Region is famed as the country’s largest milk-producing area. But overexploitation of groundwater resources has combined with the effects of climate change to give the region a more dubious distinction. The remaining water supplies are contaminated with arsenic, and related rates of cancer are well above the national average."

"Food is getting elbowed out of the discussion on climate change, which could spell disaster for the 1 billion people who will be added to the world's population in the next 15 years. That's the word today from scientists wondering why food and sustainability get such short shrift when it comes to thinking about how humans will adapt to climate change."
