Fertilizer use fuelling climate-warming nitrous oxide emissions, study says
London | Reuters — Rising use of nitrogen-based fertilizers is driving up global emissions of nitrous oxide, a lesser-known greenhouse gas, complicating efforts to limit climate change, scientists reported in a study on Wednesday. Most of the focus in curbing climate-warming gas emissions has focused on the most abundant, carbon dioxide, and one of the […] Read more

U.S. beef ranchers sour on Burger King lemongrass ration
RBI arm launches '#CowsMenu' program, 'Reduced Methane' Whopper
A new U.S. sustainability campaign from one of the world’s biggest fast food chains, training its lens on beef cattle passing gas, has “disappointed” some cattle producers while also proposing its own new feedlot ration as a way to help cut emissions. Burger King, owned by Toronto-based Restaurant Brands International, on Tuesday launched the “#CowsMenu” […] Read more

Researchers seek producer feedback on environmental assessment software
Researchers are taking a deeper look at practices that affect soil carbon and the role of wetlands in the fourth version of Holos, which allows producers to calculate their greenhouse gas emissions
A new version of an on-farm environmental assessment software is in the works, and researchers are looking for producer feedback. Scientists at Lethbridge’s Agriculture and Agri-Food Canada Research and Development Centre are enhancing the whole-farm Holos model software for measuring and assessing the environmental impact of Canadian agricultural management practices, with full release anticipated by […] Read more

Canada’s ag output seen likely rising under climate change
CNS Canada — A new United Nations report suggests just how climate change will reshape agriculture by 2050 — and that Canada’s production capacity stands to benefit. International trade will play an ever-larger role in helping to feed people in food-deficient regions, as warmer temperatures and less precipitation will damage yields in many tropical areas, […] Read more

Cattle versus climate: Where’s the beef?
Livestock production’s environmental impact is complicated but if done right, it’s good for the planet, says author
It’s become accepted wisdom that cattle production is worse for the environment than gas-guzzling SUVs — but it’s not true. “We’re told over and over again that cattle are bad for the environment and, therefore, everybody should eat less beef,” said Nicolette Hahn Niman, author of Defending Beef: The Case for Sustainable Meat Production. “We’re […] Read more

VIDEO: The battle of the belch: cutting methane from cattle
Scientists in Scotland are investigating ways to cut the amount of methane emitted by cattle, paving the way for the breeding of low-emission livestock. Matthew Stock reports for Reuters.

Drilling down on carbon sequestration
New 10-year study looks for a more accurate formula to calculate the carbon-swallowing value of native grass
Ranchers in all three Prairie provinces are taking part in a decade-long study to assess the cumulative effect of different grazing systems on carbon sequestration and other ecological benefits from a working ranch. In each province, 10 pastures managed under adaptive multi-paddock (AMP) grazing systems for at least 10 years will be paired with neighbouring […] Read more
Last five years were hottest on record
Morocco/Reuters – The past five years were the hottest on record with mounting evidence that heat waves, floods and rising sea levels are stoked by man-made climate change, the United Nations weather agency said on Tuesday. Some freak weather events would have happened naturally but the World Meteorological Organization (WMO) said greenhouse gas emissions had […] Read more

Ignoring Trump, UN talks seek to turn climate pledges into action
Morocco/Reuters – Almost 200 nations began work on Monday to turn promises for fighting climate change into action at a UN conference that played down threats to a 2015 global agreement if Republican Donald Trump wins the U.S. presidency. At the start of two-week talks in Morocco, many delegates wore badges with a smiling picture […] Read more

Man-made warming dates back almost 200 years, study says
Oslo | Reuters — Man-made greenhouse gases began to nudge up the Earth’s temperatures almost 200 years ago, as the Industrial Revolution gathered pace, far earlier than previously thought. Greenhouse gas emissions from industry left their first traces in the temperatures of tropical oceans and the Arctic around 1830, researchers wrote in a recent journal […] Read more
