Study finds a link between neonic pesticides and honeybee deaths

Grist: A new study, published on Thursday, shows a correlation between honeybee colony deaths and neonicotinoid pesticide usage in the United Kingdom. Neonicotinoids generally come as a seed coating. When the seed sprouts, it takes in the pesticide, which then protects it against predators. But if that plant flowers, small amounts of the pesticide will linger in the pollen and nectar, which may hurt the beneficial insects, like bees, visiting those blooms to feed. There`s some controversy about this:...

Humans: The Worst Predators on the Planet

EcoWatch: Watch any nature documentary and you’ll see the same story unfold time and time again: A predator approaches a group of potential prey and ends up taking down a single animal, perhaps the youngest, the weakest or the oldest among them. To get a glimpse of a superpredator, just look in the mirror: http://t.co/kvkqS0cNVu pic.twitter.com/Pcoqb9STDd -- Science News (@ScienceNews) August 20, 2015 Watch human beings doing the same thing and you’ll observe something different: They’ll either take...

Study finds climate change makes California’s drought worse

Reuters: Climate change has aggravated California's devastating drought, causing between 8 and 27 percent of the dry conditions afflicting the nation's most populous state, a study released on Thursday has found. The study, published this week in Geophysical Research Letters, is the first paper to estimate how much climate change has exacerbated the state's drought by sending moisture from plants and soils into the air, according to Columbia University, where the lead author works. Researchers examined...

July Was the Hottest Month On Record

Associated Press: Earth just keeps getting hotter. July was the planet's warmest month on record, smashing old marks, U.S. weather officials said. And it's almost a dead certain lock that this year will beat last year as the warmest year on record, they said. July's average temperature was 61.86 degrees Fahrenheit, beating the previous global mark set in 1998 and 2010 by about one-seventh of a degree, according to figures released Thursday by the National Oceanic and Atmospheric Administration. That's a large...

EPA Says It Doesn’t Monitor Abandoned Mines

Guardian: The Environmental Protection Agency (EPA) has said it has no system for monitoring hundreds of thousands of abandoned mines that pock the American landscape, or knowing which one could be the source of the next big toxic spill. “EPA does not maintain records of the number of mines or tailings dams in the US,” a spokesman for the federal agency told the Guardian. In the western US, the EPA estimates there may be 161,000 abandoned “hard rock” mines, where metals such as gold, silver and copper were...

More Than Three-Quarters of Canada’s Oil Sands Being Produced At a Loss

Reuters: Aug 20 More than three-quarters of Canada's daily output of 2.2 million barrels of crude from oil sands is being produced at a loss at current prices, research from analysts at TD Securities shows, although producers are unlikely to halt operations. Only two mining and upgrading projects - Canadian Natural Resources Ltd's Horizon project and Suncor Energy's Millennium mine - are producing synthetic crude for less than its current outright price around $36 a barrel, analyst Menno Hulshof said on...

Some permafrost might soak up methane as climate warms

ArsTechnica: Talk of a warming planet often focuses on places that are cold. Glaciers shrink and raise sea level. Arctic sea ice dwindles, opening an actual northwest passage in the summer. And permafrost thaws, pulling vast amounts of organic matter out of the freezer to spoil and add to the greenhouse gases in the atmosphere. Lots of research has focused on organic-rich permafrost and the amount of carbon dioxide and methane it could produce as microbes break down all that food. But that’s only a slice of...

Toxic Algae Invade Guatemala’s Treasured Lake Atitlan

Environment News Service: A thick bloom of algae known as cyanobacteria appeared in Lake Atitlan on August 3, the first such occurrence since 2009. But help appears to be on the way in the form of funds to upgrade the waste water treatment system and water supply in the Atitlán basin. Located in the Guatemalan Highlands of the Sierra Madre mountain range, Lake Atitlan is the deepest lake in Central America and one of the most beautiful. The surrounding area became a national park in 1955. An infestation of microalgae...

Three Firefighters Die as Wildfires Scorch the West
