Inflammatory bowel disease (IBD) has become common in the Western world, but its causes remain unclear. With the dramatic increase of cases in Asia in recent years—echoing the disease’s drastic rise in the West decades earlier—investigators have another shot at studying environmental contributors to IBD as it emerges in new …
Canadian Prime Minister Justin Trudeau faces a challenging day of climate change talks on Thursday with leaders of the country's 10 provinces, one of whom opposes a key part of Ottawa's plan to cut greenhouse gas emissions. Trudeau, whose Liberals won power last year on the back of a promise …
This IEA Bioenergy report provides an overview of the current status of biomass cofiring. The report shows that the firing and co-firing of biomass as a replacement for coal in large pulverised coal boilers can be a very attractive option for the utilisation of biomass materials for power production, and …
Canada has continued to harvest its vast natural resources and witnessed a shale revolution alongside rising oil sands production and investment in the energy sector over the past five years. The medium-term outlook for gas/oil production and exports, however, is challenging amid uncertainties around pipeline developments and an era of …
A time series of organic carbon export from Gulf of Maine (GoM) watersheds was compared to a time series of biological, chemical, bio-optical, and hydrographic properties, measured across the GoM between Yarmouth, NS, Canada, and Portland, ME, U.S. Optical proxies were used to quantify the dissolved organic carbon (DOC) and …
Favorable weather conditions at breeding grounds for monarch butterflies in Mexico are expected to help raise their numbers to possibly more than 100 million this year, about triple of a few years ago, a study released on Thursday said.

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 …
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 …

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 …
More than 17,000 marine species worldwide remain largely unprotected, a new study reveals. Published in the international journal Scientific Reports, the study looked at various species of marine life including whales, sharks, rays and fish. The researchers found that 97.4 per cent of species have less than 10 per cent …
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.

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 a study released on Thursday. Eight industrialized nations - Australia, Canada, France, Germany, Italy, Japan, the United …
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 it is not doing enough to combat climate change.
