Canada’s Zombie Forests

How logging has quietly taken its toll on the country’s woodland.

Although Canada has developed a reputation as a responsible steward of its massive — and environmentally crucial — boreal forests, a new study published in the journal Land calls that reputation into question. The analysis, by researchers at Australia’s Griffith University, found that 35.4 million acres of the country’s evergreen forests in the provinces of Ontario and Quebec have been effectively lost to logging since 1976. The government-approved methods used to regenerate those forests — which require loggers to replant cleared areas or show that the region will recover on its own — have had a devastating result, as similar practices have had in many other parts of the world.

While 56 million acres of older trees remain across the two provinces, that acreage is now interspersed with patchworks of newly planted trees chosen for their future suitability for logging, not for purposes of ecological diversity or wildfire prevention. “The Canadian government claims to have managed the forest according to the principles of sustainable forest management,” Brendan Mackey, the study’s lead author, toldThe New York Times. “But its notion of sustainability is really tied to maintaining and maximizing wood production and ensuring the regeneration of commercially desirable trees. That has a lot of implications for biodiversity.”

Canada’s forest managers say that “At 0.02% of its forested area, [the rate of] deforestation in Canada is among the world’s lowest,” which sounds impressive until this caveat: “an area with very young trees is still a forest. The term ‘deforestation’ refers to land that has been cleared of trees and permanently converted to another use.” It’s a bit like claiming that a zombie is a healthy, normal person, simply because it seems to be alive. So while Canada may not have widespread deforestation, what it does have are swaths of newer trees that are far less effective than their forebears when it comes to carbon capture, species diversity, and wildfire prevention. “Forest degradation is the more important metric for Canada because it really captures more of what’s actually happening,” Peter Wood, of the University of British Columbia, told the Times. “Canada has downplayed the impact of the forest industry.”

The Best Idea From Today’s Big Oil Hearing

It was always a fantasy to think that the Senate Committee on the Budget’s hearing on oil disinformation would actually be about oil disinformation. It was still shocking, though, how far off the rails things ran.

The hearing concerned a report released Tuesday by the committee along with Democrats in the House documenting “the extensive efforts undertaken by fossil fuel companies to deceive the public and investors about their knowledge of the effects of their products on climate change and to undermine efforts to curb greenhouse gas emissions.” This builds on the already extensive literature documenting the fossil fuel industry’s deliberate dissemination of lies about climate change and its role in causing it, including the 2010 book Merchants of Doubt and a 2015 Pulitzer Prize-nominated series from Inside Climate News on Exxon’s climate denial PR machine. But more, of course, is more.

Air Quality Data for the Rich

Wealth bias shows up in the strangest places — including, according to new research, PurpleAir sensor data.

Everyone loves a public good, and one of the classic examples is clean air. When I breathe in clean air, no one else gets any less of it, and you can’t exclude people from enjoying it.

But how do we know whether the air we’re breathing is clean? And is that information a public good?

It’s Never Too Early to Start Thinking About COP

President-Designate Mukhtar Babayev kicked off the climate diplomatic year in Berlin.

The United Nations’ climate summit in Dubai ended last December with a mad dash to lock in a location for this year’s gathering. Which is how we wound up with yet another petrostate — Azerbaijan — as the host.

On Thursday at a climate conference in Berlin, Azerbaijan’s minister of ecology and natural resources and COP29’s President-Designate Mukhtar Babayev outlined his vision for the November get-together. “Our previous promises now need to be delivered, not re-interpreted. Fulfilled, not re-negotiated,” he told participants in the Petersberg Climate Dialogue, according to a transcript of his prepared remarks. “Everyone has a duty to make sure their actions match their words.”
