Great Barrier Reef survival relies on halting warming, study warns

Mar 16 2017 — — Australia’s Great Barrier Reef can be saved only if urgent steps are taken to reduce global warming, new research has warned. Attempting to stop coral bleaching through any other method will not be sufficient, according to scientists. The research, published in the journal Nature, said bleaching events should no longer be studied individually, but as […]

‘Shell knew’: oil giant’s 1991 film warned of climate change danger

Feb 28 2017 — — The oil giant Shell issued a stark warning of the catastrophic risks of climate change more than a quarter of century ago in a prescient 1991 film that has been rediscovered. However, since then the company has invested heavily in highly polluting oil reserves and helped lobby against climate action, leading to accusations that Shell […]

Driving momentum for sustainable transportation

Feb 27 2017 — — Canada has a tailpipe problem. The country’s 24 million or so cars and trucks together generated 23% of Canada’s greenhouse gas emissions in 2014, and were responsible for three quarters of the growth in energy-related carbon emissions since 1990.

Scientists propose refreezing Arctic in battle against climate change

Feb 16 2017 — — A group of researchers has proposed using wind-powered pumps to refreeze the Arctic. The proposal seems ambitious: it involves 10 million devices deployed over 10 per cent of the Arctic, at a cost of $500 billion US. Lead author of the paper, astrophysicist Steven Desch, concerned about what some climatologists predict to be an ice-free […]

Refuelling Alberta coal plants with biomass

Feb 15 2017 — — Using biomass at shuttered coal-fired plants could help provinces meet their climate targets for a lower cost. The Alberta power system is set for radical transformation between now and 2030. According to the Climate Leadership Plan, the province will end all coal-fired power generation and get 30 percent of its energy from renewable sources by […]

Could Trump derail Canada’s climate and energy plan?

Feb 9 2017 — — The Trudeau government’s lofty ambitions of fighting climate change are unlikely to succumb to Donald Trump’s presidency with a bang, but they could go out with a whimper. In this article, based on oil industry documents obtained by Greenpeace Canada under freedom of information legislation, I explore how the industry’s lobbyists are attempting to weaken […]

Canada’s carbon leak problem

Feb 1 2017 — — Most people I talk to have never heard of carbon leaks, which is when carbon policy causes emissions to be displaced to another jurisdiction. Yet the recent election in the United States heightens the importance of Canada taking carbon leaks into account, as it is a member of the North American Free Trade Act. Carbon […]

Canada cannot have it both ways on climate and fossil fuel expansion

Jan 26 2017 — Marc Lee — With great fanfare and a claim that “Canada is back,” Prime Minister Trudeau helped usher in the Paris Agreement on climate change in December 2015. Since then, however, the federal government has pushed to expand fossil fuel production through new bitumen pipelines and LNG terminals. This contradiction points to a loophole in the Paris Agreement, […]

For third straight time, Earth sets hottest year record

Jan 18 2017 — — U.S. government scientists say the Earth sizzled to a third straight heat record last year. They mostly blame man-made global warming with help from a natural El Nino, which has since disappeared. The figures announced Wednesday come from NASA and the National Oceanic and Atmospheric Administration, which measure global temperatures in slightly different ways. They […]

Crawling in crustaceans: Scientists study link between warmer ocean, booming lobster population

Jan 18 2017 — Paul Withers — Federal scientists are exploring connections between a warming Atlantic ocean and record lobster landings off southwestern Nova Scotia and in the Bay of Fundy. Adam Cook, lead lobster research scientist for the Department of Fisheries and Oceans, said those locations have seen the greatest temperature increases too. He said there’s clearly a relationship between temperatures […]

Obama administration gives $500m to UN climate change fund

Jan 18 2017 — — The US government has given half a billion dollars to the UN’s Green Climate Fund, just three days before Donald Trump takes office. Barack Obama’s outgoing administration announced the contribution of $500m (£406m; €468m) on Tuesday, bringing the total funds to date to $1bn. Mr Obama pledged in 2014 to give $3bn to help tackle […]

Emissions targets in the EU and Canada

Jan 17 2017 — — The EU and Canada committed to achieving specific greenhouse gas emissions targets by 2030. A look at how they’re doing so far. Last October, the European Union and Canada signed the Comprehensive Economic Trade Agreement (CETA). Shortly thereafter, in early November, both ratified the Paris Agreement on reducing greenhouse gas (GHG) emissions, committing them to […]

Global warming data that riled doubters is confirmed

Jan 4 2017 — — A new independent study shows no pause in global warming, confirming a set of temperature readings adjusted by U.S. government scientists that some who reject mainstream climate science have questioned. The adjustments, made in 2015 to take into account how ocean temperatures have been measured over the decades, riled a House committee and others who […]

Arctic heatwave could break records

Dec 24 2016 — — Temperatures at the North Pole could be up to 20 degrees higher than average this Christmas Eve, in what scientists say is a record-breaking heatwave. Climate scientists say these unseasonably warm weather patterns in the Arctic region are directly linked to man-made climate change. Temperatures throughout November and December were 5C higher than average. It […]
