An earthquake of 4.6 magnitude in western Canada was caused by fracking, according to the region's energy regulator.

Management of temperate forests has the potential to increase carbon sinks and mitigate climate change. However, those opportunities may be confounded by negative climate change impacts. We therefore need a better understanding of climate change alterations to temperate forest carbon dynamics before developing mitigation strategies. The purpose of this project was to investigate the interactions of species composition, fire, management and climate change on the Copper–Pine creek valley, a temperate coniferous forest with a wide range of growing conditions.

Carsharing exemplifies a growing trend towards service provision displacing ownership of capital goods. We developed a model to quantify the impact of carsharing on greenhouse gas (GHG) emissions. The study took into account different types of households and their trip characteristics. The analysis considers five factors by which carsharing can impact GHG emissions: transportation mode change, fleet vintage, vehicle optimization, more efficient drive trains within each vehicle type, and trip aggregation.

Report on Guatemalan mine accuses the government and company running it, Tahoe Resources, of a military response to opposition

Ongoing research and technology developments hold the promise of rapid production and large-scale deployment of strain-specific or cross-protective vaccines for novel influenza viruses. We sought to investigate the impact of early vaccination on age-specific attack rates and evaluate the outcomes of different vaccination strategies that are influenced by the level of single or two-dose vaccine-induced protections. We developed and parameterized an agent-based model for two population demographics of urban and remote areas in Canada.

More than 17,000 marine species worldwide remain largely unprotected, a new study reveals.

Wealthy nations spend 40 times as much money subsidizing fossil fuel production as they contribute to the Green Climate Fund to help poor countries adapt to global warming, a research group said in

Manitoba pledged on Thursday to cut greenhouse gas emissions and start a carbon cap and trade system, the latest Canadian province to set long-term targets to fight climate change.

The Canadian province of Alberta, home to the country's controversial oil sands, said on Sunday it will implement an economy-wide tax on carbon emissions in 2017, addressing long-standing criticism

A population-based propensity-score matched cohort study design was used based on the Ontario population from the Canadian Community Health Survey (2001-2010). Participants were adults aged 20 years or older who moved from a low walkability neighborhood (defined as any neighborhood with a Walk Score<90) to either a high (Walk Score≥90) or another low walkability neighborhood. The incidence of hypertension was assessed by linking the cohort to administrative health databases using a validated algorithm. Propensity-score matched Cox proportional hazard models were used.
