As the use of hydraulic fracturing has grown, so have concerns about its environmental and public health impacts. One concern is that hydraulic fracturing fluids used to fracture rock formations contain numerous chemicals that could harm human health and the environment, especially if they enter drinking water supplies. The opposition of many oil and gas companies to public disclosure of the chemicals they use has compounded this concern. ... The most widely used chemical in hydraulic...

OTTAWA - Prime Minister Stephen Harper heads to the Far North next week, with his annual trek focusing on the Western Arctic and developing the region's natural resources. The five-day north of 60 trip gears up in Whitehorse Monday, with stops at copper and gold mine Minto Mine and Norman Wells, an oil drilling and exploration hub, in the Northwest Territories. The prime minister then heads to Cambridge Bay, Nunavut, where two years ago he announced a new $81 million high Arctic research...

SARNIA, ON - Two environmental groups have withdrawn their application for a Federal Court review of permits allowing Bruce Power to ship radioactive waste on the Great Lakes. The Sierra Club Canada and the Canadian Environmental Law Association pulled the application due to federal changes to the environmental approvals process in the budget and because the permits issued by the Canadian Nuclear Safety Commission had expired, said the Sierra Club's executive director John Bennett....

Exposure to radioactive material released into the environment has caused mutations in butterflies found in Japan, a study suggests. Scientists found an increase in leg, antennae and wing shape mutations among butterflies collected following the 2011 Fukushima accident. more

Pink-footed geese appear to be avoiding new offshore wind farms when returning to the UK, a study has suggested. By monitoring the movement of the birds over four years, researchers were able to detect changes in flight patterns around two newly erected wind farms. The results show that this species of geese, at least, identify wind farms as a threat and alter their flight to avoid turbine blades, the authors said. more

As cabinet ministers are reportedly readying themselves themselves to consider the implications of China-owned energy behemoth CNOOC's bid to take over Calgary-based Nexen, the latest communications filings reveal the company at the centre of the potentially contentious deal lost no time fanning out across official Ottawa after going public with the offer last month. more

A new analysis of worldwide temperatures over the past 60 years has found more evidence that global warming is already upon us, and is responsible for extreme heat waves — such as the ones in Russia in 2010 and in Texas and Oklahoma last year. more

A new study of hydraulic fracturing - or "fracking" - in the United States, finds current methods for waste water disposal put drinking water at risk. Fracking involves pumping water, sand and other chemicals deep underground at high pressure to fracture rocks, allowing trapped natural gas to flow and be pumped to the surface. While resource companies have used the technology on a small scale for decades, it's expected to ramp up significantly as deep shale gas...

Buried within the more than 400 pages of this spring’s federal omnibus budget bill is an invitation for resource companies to open a new frontier in Canadian oil: the Gulf of St. Lawrence. The gulf, which touches the coastlines of Canada’s five easternmost provinces, is the world’s largest estuary. It’s home to more than 2,000 species of marine wildlife — an ecosystem integral to the health of our Atlantic and Great Lakes fisheries. Now, due to measures deep...

Little-known statistics compiled by Japan’s Fisheries Agency have documented persistently high post-Fukushima radiation levels in fish. Are fish from the Pacific Ocean and Japanese coastal and inland waters safe to eat 16 months after the Fukushima nuclear disaster? Governments and many scientists say they are. But the largest collection of data on radiation in Japanese fish tells a very different story. In June, 56 percent of Japanese fish catches tested by the Japanese...
