A new study by NASA and University of California, Irvine, scientists finds more than 75 percent of the water loss in the drought-stricken Colorado River Basin since late 2004 came from underground resources. The extent of groundwater loss may pose a greater threat to the water supply of the western United States than previously thought. This study is the first to quantify the amount that groundwater contributes to the water needs of western states. According to the U.S. Bureau of Reclamation, the federal water management agency, the basin has been suffering from prolonged, severe drought since 2000 and has experienced the driest 14-year period in the last hundred years.

Europe's installed wind capacity will increase at a slower rate to the end of the decade than previously estimated, due to regulatory uncertainty and weak economic growth, an industry association said on Wednesday (23 July). European Union countries will have a combined 192.4 gigawatts (GW) of installed wind energy capacity by 2020, 64% higher than 2013 levels, the European Wind Energy Association (EWEA) said in a report.

Chinese businessman Yi Zong decided to install charging stations himself after he purchased his Tesla earlier this year. He realized that charging his vehicle would be a problem in China because, well, there are few stations in that country. Zong installed recharging facilities on his own dime, or yuan as the case may be, in 16 cities between Beijing and his home in Guangzhou — a 3,573-mile corridor. Zong, one of the first Chinese owners of the Model S, calls his project the country’s "first electric-charging road," according to a report at Caixin Online, a Beijing-based media group.

More extreme droughts, floods and wildfires – these are just some of the impacts of climate change that won't just occur in the distant future to our great-great grandchildren, but are happening now. To address the changing climate's current effects on communities in the U.S., President Barack Obama announced a plan to strengthen national infrastructure and help cities, states and tribal communities better prepare for and recover from natural disasters.

You have probably heard that melting permafrost is a big contributor to increasing the levels of greenhouse gases in our atmosphere, and that melting permafrost may even cause an unstoppable acceleration of global warming. New research, however, supported by the National Science Foundation (NSF), counters this widely-held scientific view that thawing permafrost uniformly accelerates atmospheric warming, indicating instead that certain arctic lakes store more greenhouse gases than they emit into the atmosphere. The study, published this week in the journal Nature, focuses on thermokarst lakes, which occur as permafrost thaws and creates surface depressions that fill with melted fresh water, converting what was previously frozen land into lakes.

Residents of California have been noting something disconcerting when they hit the grocery store this year: it's a terrible year for stone fruit. Despite the fact that it's the height of summer, peaches, nectarines, apricots, plums, cherries and their ilk are much more expensive than unusual, and of much poorer quality, too. What's going on? The answer lies in the state's extreme drought, which wreaked havoc on numerous crops this year, including stone fruit. The state's agriculture may be undergoing some major shifts in the coming years thanks to climate change and natural shifts in rainfall levels, and it's not the only region looking at a drier future.

Scientists at the National Center for Atmospheric Research (NCAR) and partner organizations are launching a major field project across the northern Front Range of Colorado this month to track the origins of summertime ozone, an invisible but harmful pollutant. The researchers will use specially equipped aircraft, mobile radars, balloon-mounted sensors, and sophisticated computer simulations to measure local and far-flung pollution sources. Results from the month-long study will provide needed information to officials seeking to ensure that air in the region is healthy to breathe.

Californians who waste water will have to pay up to $500 a day for their extravagance under new restrictions approved Tuesday by the State Water Resources Control Board. The move comes after the board concluded that voluntary conservation measures have failed to achieve the 20 percent reduction in water use that Gov. Jerry Brown was hoping for, reports The Associated Press. In fact, a survey by the board showed a 1 percent increase in water use in May compared to the same month a year ago.

Millions of urban Europeans are exposed to aviation noise that contributes to stress, high blood pressure and even weight gain, say health specialists who want stronger measures to make flying quieter. While new-generation jet engines are on average 75% quieter than than their 20th century predecessors, the advance in technology has been offset by a steady rise in flights and a demand for bigger passenger planes.

London's urban heat island effect, which keeps night-time temperatures in the capital warmer than in surrounding rural areas, may have been underestimated by up to 45 per cent. The heat can pose serious health risks, particularly for the elderly and very young.
