Throughout the U.S., trees are dying at an astonishing rate. The reasons for the die-off vary from location to location — drought, disease, insects and wildfires — but the root cause in many of these cases is the same: climate change. The epidemic is even threatening the oldest white oak tree in America, a 600-year-old giant in New Jersey that predates Columbus’ visit to …
Clues from prehistoric droughts and arid periods in California show that today’s increasing greenhouse gas levels could lock the state into drought for centuries, according to a study led by UCLA professor Glen MacDonald. The study, published today in the Nature.com journal Scientific Reports, looked at how natural climatic forces contributed to centuries-long and even millennia-long periods of dryness in California …

I’ve been an avid hiker my whole life. From the time I first strapped on a backpack and headed into the Sierra Nevada Mountains, I was hooked on the experience, loving the way being in nature cleared my mind and helped me to feel more grounded and peaceful. But, even though I’ve always believed that hiking in nature had many …
On April 1, 2015, California Governor Jerry Brown ordered officials to impose mandatory water restrictions in his drought stricken state for the first time in history. The news was carried around the world. “Climate change” was named as the culprit — and it is. Glaciers are melting in the arctic and drastically-reduced snowfall in the Sierra Nevada Mountains has lowered the amount of run-off that …
The federal and state governments illegally opened up 400,000 acres for fracking in Southern California, which already has thousands of such dangerous oil and gas wells, environmentalists claim in court. The Center for Biological Diversity and Los Padres Forestwatch sued the U.S. Bureau of Land Management, the Secretary of the Interior and the director of California’s Bureau of Land Management …
On April 1, California Governor Jerry Brown stood in a field in the Sierra Nevada Mountains, beige grass stretching out across an area that should have been covered with five feet of snow. The Sierra’s snowpack — the frozen well that feeds California’s reservoirs and supplies a third of its water — was just eight percent of its yearly average. …
The firefighters are primed, hoses at the ready. May and June are often the peak months for forest fires in the southwest of the US, and the outlook for this year is grim. “I wish I could have some hope,” says Dr Wally Covington, director of the Ecological Restoration Institute at North Arizona University. “It’s just a terrible situation in …
Unlike so many industrial innovations, the revolving door was not developed in Detroit. It took its first spin in Philadelphia in 1888, the brainchild of Theophilus Van Kannel, the soon-to-be founder of the Van Kannel Revolving Door Company. Its purpose was twofold: to better insulate buildings from the cold and to allow greater numbers of people easier entry at any given …
Almonds: crunchy, delicious, and…the center of a nefarious plot to suck California dry? They certainly have used up a lot of ink lately—partly inspired by our reportingover the past year. California’s drought-stricken Central Valley churns out 80 percent of the globe’s almonds, and since each nut takes a gallon of water to produce, they account for close to 10 percent of the state’s annual agricultural water …
