Fracking's Dark Secret
We've long known extracting oil and gas comes with negative consequences, and rapid expansion of hydraulic fracturing, or fracking, increases the problems and adds new ones—excessive water use and contamination, earthquakes, destruction of habitat and agricultural lands and methane emissions among them.
As fossil fuel reserves become depleted, thanks to our voracious and wasteful habits, extraction becomes more extreme and difficult. Oil sands mining, deep sea drilling and fracking are employed because easily accessible supplies are becoming increasingly scarce. The costs and consequences are even higher than with conventional sources and methods.
Fracking involves drilling deep into the Earth, and injecting a high-pressure stream of water, sand and chemicals to break apart shale and release gas or oil. In British Columbia, politicians tout liquefied natural gas as an economic panacea, a product we can export around the world to create jobs and prosperity at home. More than 80 percent of BC's natural gas is fracked, and as fracking increases, the percentage rises.
Of the many problems with the industry, methane emissions from fracked and conventional operations are among the most serious. Methane is at least 84 times more potent than carbon dioxide as a heat-trapping gas over the short term. Researchers estimate it's responsible for 25 percent of already observed climatic changes. One difference between methane and CO2: Methane remains in the atmosphere for a shorter time—around a decade, compared to many decades or centuries for CO2.
Methane's relatively short lifespan means reducing the amount entering the atmosphere will have major and rapid results. Cutting methane emissions from the oil and gas sector is one of the cheapest, most effective ways to address climate change. The technology to do so already exists. It's absurd that the industry is leaking the very resource it wants to sell.
Methane comes from a number of sources, including animal agriculture and natural emissions. Global warming itself means methane once trapped in frozen ground or ice is escaping into the air.
The oil and gas industry is one of the major emitters. A field study by the David Suzuki Foundation and St. Francis Xavier University found methane pollution from BC's oil and gas industry is at least 2.5 times higher than BC government estimates.
In 2015 and 2016, foundation researchers joined St. Francis Xavier University's Flux Lab under the supervision of David Risk, an expert in measurement, detection and repair of fugitive emissions. Using gas-detection instruments mounted on a "sniffer truck," they traveled more than 8,000 kilometers in northeastern BC. They found methane emissions from BC's Montney region alone are greater than what the provincial government has estimated for the entire industry! (Montney represents about 55 percent of BC's oil and gas production). David Suzuki Foundation senior scientist John Werring followed up on and corroborated that research by measuring point-source methane emissions from more than 170 oil and gas sites.
The research, available in the journal Atmospheric Chemistry and Physics, found Montney operations leak and intentionally release more than 111,800 tonnes of methane into the air annually—equivalent to burning more than 4.5 million tonnes of coal or putting more than two million cars on the road. Half of all well and processing sites in the region are releasing methane.
This research shows that the oil and gas sector is the largest source of climate pollution in BC, surpassing commercial transportation—and it contradicts claims that natural gas or LNG is a clean fuel or that it's useful to help us transition from other fossil fuels.
Given these results and other studies—including one in Alberta that found the amount of methane leaking from Alberta operations in one year could heat 200,000 homes—it's time for all levels of government to get industrial methane emissions under control.
Beyond existing commitments to reduce methane emissions by 45 percent, governments must work to eliminate them from this sector by 2030, with strong regulations, monitoring and oversight. We need better leak detection and repair, improved reporting and enforcement and methods to capture emissions rather than burning them.
Climate change is a serious issue, and methane emissions are a significant contributor. Getting them under control is a quick, cost-effective way to help address the problem. What's stopping us?
As Trevor Noah noted during The Daily Show episode last night (starts at 2:25), the real reason Trump has these rallies is to "get back in front of his loyal crowds and feed of their energy." Noah believes that "Trump supporters are so on board with their dude he can say anything and they'll come along for the ride."

Seismic airguns exploding in the ocean in search for oil and gas have devastating impacts on zooplankton, which are critical food sources for marine mammals, according to a new study in Nature. The blasting decimates one of the ocean's most vital groups of organisms over huge areas and may disrupt entire ecosystems.
And this devastating news comes on the heels of the National Marine Fisheries Service's proposal to authorize more than 90,000 miles of active seismic blasting. Based on the results of this study, the affected area would be approximately 135,000 square miles.

Is coconut oil:
- good for you
- bad for you
- neither good nor bad
- scientists don't know
The subject of this question is the source of a disagreement. Initially, the question was thought to be settled decades ago, when scientist Ancel Keys declared all saturated fats unhealthy. Coconut oil, which is solid at room temperature, is a saturated fat.
The U.S. Fish and Wildlife Service removed grizzly bears in the Greater Yellowstone region on Thursday from the Endangered Species List. The decision comes despite serious concerns in the scientific community about a declining, isolated population with diminishing food resources and record-high mortalities, as well as strong opposition from an unprecedented number of Tribal Nations.

ArborGen Corporation, a multinational conglomerate and leading supplier of seedlings for commercial forestry applications, has submitted an approval request to the U.S. Department of Agriculture, Animal and Plant Health Inspection Service to deregulate and widely distribute a eucalyptus tree genetically engineered (GE) to be freeze tolerant. This modification will allow this GE variety to be grown in the U.S. Southeast. The reason this non-native and highly invasive tree has been artificially created to grow outside of its tropical environment is to greatly expand production capacity for the highly controversial woody biomass industry.

Many health conscious consumers are reducing their consumption of red meat in favor of chicken—especially products labeled and promoted as "100% natural"—believing they are a healthier option produced without routine antibiotics, artificial substances or other drugs.
"We have given our planet the disastrous gift of climate change ... When we we have reached similar crises there has usually been somewhere else to colonize ... But there is no new world, no utopia around the corner," he said. "We are running out of space, and the only places to go to are other worlds."
Just like John Oliver predicted, Robert E. Murray has filed a lawsuit in response to the Last Week Tonight host's June 18 show about coal that devoted a large segment skewering the Murray Energy Corporation CEO.
