The Quadra Project: A Moment for Methane

Carbon dioxide (CO2—a single atom of carbon with two attached atoms of oxygen) gets most of the attention as the cause of global warming
because it can persist in the atmosphere for centuries. Methane is a
gas (CH4—a single carbon atom with four attached atoms of hydrogen)
that deserves attention, especially because every portion of a degree
is crucial in avoiding the worst consequences of global warming.

Although methane persists in the atmosphere for only about 20 years,
it is about 80 times more warming than carbon dioxide, so its
importance in the short term is critical. “Cutting methane is the
single most important strategy in slow near term warming,” says
Durwood Zaelke, the president of the Institute for Governance and
Sustainability (The Guardian Weekly, November 21, 2015). Its
pre-industrial atmospheric concentration was about 715 parts per
billion, and its 2025 level is presently measured at about 1930 ppb,
an increase of nearly 270%. Because of the short life of methane,
these high levels are maintained and increased by the continuous and
rising rate of emissions.

The Quadra Project – What’s the Beef?

A team of Australian and Japanese researchers have quantified the damage to human health that is done by eating red meat. If people shifted their diets from beef to such forage fish as anchovies, herring and sardines, the study found, an estimated 750,000 lives could be saved per year (The Guardian Weekly, April 19, 2024). The comprehensive study of 130 countries identified that human health deteriorates as red meat consumption rises.

The study also revealed the clear environmental benefits to shifting away from beef. Instead of feeding these nutritious forage fish to animals, which are how most of these aquatic species are consumed, the nutritional benefits that were passed directly to people would reduce the diseases caused by excessive beef consumption, but also save huge amounts of agricultural land that is presently used to raise cattle for beef.

Farming for the climate future

Canada’s National Observer, Local Journalism Initiative Reporter

Tamara McPhail’s morning chore never changes, but the infinite variety of sounds and seasons makes milking cows every day unique. 

On this spring morning, Zinnia and her new calf Equinox are restless and nagging — bellowing, bleating and raring to get outside into the fields. 

Other mornings, they greet McPhail with gentle grunts and low moos as she enters the barn as if relishing the connection they’ll have with her. 

“I’m really attached to the livestock system,” says McPhail, who along with her partner Adam Schick, has been part of a team stewarding the land at Linnaea Farm on Cortes Island, B.C., closing on 25 years.

Think meat is expensive? What about the environmental impact?

By Cloe Logan, National Observer, Local Journalism Initiative Reporter

Meat is expensive — but we’re still paying far less for it than the cost of its environmental impact, according to a study released this week.
