Though parasitic mites continue to infect and kill honeybees, a new study suggests they are not to blame for colony collapse disorder (CCD), the phenomenon blamed for rapidly depleting the world's honeybee population -- pesticides are.
Harvard researchers, working with beekeepers in Massachusetts, kept tabs on 18 bee colonies, six hives in three different locations -- from October 2012 to April 2013. Half the colonies were treated with a non-lethal dose of two neonicotinoid pesticides.
Pesticides to blame for honeybee colony collapse disorder, not mites
Medical experts warn against high levels of radon and radium from fracking
A group of health professionals opposed to hydraulic fracturing penned a letter Wednesday to Gov. Andrew Cuomo, calling on him to take a closer look at radon levels in shale gas before allowing fracking in New York.
The letter, signed by nine people including a representative of the American Lung Association, urges Cuomo’s administration to first examine whether gas from the Marcellus Shale has elevated levels of radon before green-lighting fracking. The state should take a closer look at radiation issues related to shale-gas before proceeding, the letter signers content.
Sentinel satellite spies speed-up of ice cap melting
Melting at one of the largest ice caps on Earth has produced a big jump in its flow speed, satellite imagery suggests.
Austfonna on Norway's Svalbard archipelago covers just over 8,000 sq km and had been relatively stable for many years. But the latest space data reveals a marked acceleration of the ice in its main outlet glacier to the Barents Sea.
The research was presented in Brussels on Thursday to mark the launch of the EU's new Sentinel-1a radar spacecraft.
New report: Climate change has 'moved firmly into the present' and nation needs to adapt
Saying that climate change has “moved firmly into the present,” a federal scientific panel Tuesday released a report cataloging the impacts of such changes, saying some would actually be beneficial “but many more are detrimental.”
The American Southeast and Caribbean regional is “exceptionally vulnerable” to rising sea levels, extreme heat events, hurricane and decreased water resources, the report said. Seven major ports in the region are vulnerable. And residents can expect a significant increase in the number of hot days – defined as 95 degrees or above – as well as decreases in freezing events.
Oklahoma earthquakes tied to oil, gas work
The U.S. and Oklahoma Geological Surveys said an increase in earthquakes in the state may be attributed to heightened oil and gas activity.
USGS said it examined the rate of increase in earthquakes in Oklahoma and found they weren't due to random fluctuations in seismic activity in that state.
The joint study found injecting wastewater underground can lead to pressure increases that may contribute to earthquakes.
"Much of this wastewater is a byproduct of oil and gas production and is routinely disposed of by injection into wells specifically designed and approved for this purpose," USGS said.
Antarctic Ice Shelf On Brink Of Unstoppable Melt That Could Raise Sea Levels For 10,000 Years
Part of East Antarctica is more vulnerable than expected to a thaw that could trigger an unstoppable slide of ice into the ocean and raise world sea levels for thousands of years, a study showed on Sunday.
The Wilkes Basin in East Antarctica, stretching more than 1,000 km (600 miles) inland, has enough ice to raise sea levels by 3 to 4 metres (10-13 feet) if it were to melt as an effect of global warming, the report said.
The Wilkes is vulnerable because it is held in place by a small rim of ice, resting on bedrock below sea level by the coast of the frozen continent. That "ice plug" might melt away in coming centuries if ocean waters warm up.
U.S. Youths sue U.S. government over climate inaction
Young people across the country are suing several government agencies for failing to develop a climate change recovery plan, conduct that amounts to a violation of their constitutional rights, says their lawyer Julia Olson.
Their futures are at stake, say the young plaintiffs.
“Climate change is the biggest issue of our time,” said 13-year-old Xiuhtezcatl Roske-Martinez, a member of nonprofit Kids vs. Global Warming, a plaintiff in the suit.
“It’s not every day you see young people getting involved politically but the climate crisis is changing all that. Every generation from here on out is going to be affected by climate change,” added Roske-Martinez, who also founded environmental nonprofit Earth Matters and organized successful actions in his hometown of Boulder, Colo.
