Black carbon lofts wildfire smoke high into the stratosphere to form a persistent plume

Science Magazine.

In 2017, western Canadian wildfires injected smoke into the stratosphere that was detectable by satellites for more than 8 months. The smoke plume rose from 12 to 23 kilometers within 2 months owing to solar heating of black carbon, extending the lifetime and latitudinal spread. Comparisons of model simulations to the rate of observed lofting indicate that 2% of the smoke mass was black carbon. The observed smoke lifetime in the stratosphere was 40% shorter than calculated with a standard model that does not consider photochemical loss of organic carbon. Photochemistry is represented by using an empirical ozone-organics reaction probability that matches the observed smoke decay. The observed rapid plume rise, latitudinal spread, and photochemical reactions provide new insights into potential global climate impacts from nuclear war. More here.

What can a large, but routine highway project teach us about our climate crisis?

Larry Powell explores that question in this picture story - "Thinking Globally. Acting Locally."

Earlier this summer, in a letter in my community newspaper, the Crossroads, I complained about a huge multi-million dollar roadbuilding project south of Shoal Lake, in southwestern Manitoba. 

Here’s why.

A convoy of dump trucks streams past my window.

Despite a standing warning from the United Nations that the construction sector needs to cut back on its huge carbon footprint “yesterday” if we are to meet our obligations under the Paris Climate Accord, a steady stream of diesel trucks rumbled through town for weeks, from dawn to dusk, right past my living and bedroom windows. (Above.)

And, scant weeks after the Parks and Wilderness Society informed us that biodiversity (the variety of plant and animal life on Earth) is declining faster than at any other time in human history, the trucks were making hundreds of round trips a day, hauling copious loads of gravel from a mine which, for years, has been transforming a beautiful and once-natural stretch of the Birdtail Valley west of here (below), into an ugly hub of commerce.

I asked an employee of the gravel mine what the future holds. He speculated that, now stocks are depleting at the present site, expansion to the north might be in the works.

Yet my letter was met with a deafening silence. I wonder if a recent study by the University of BC might help explain why. It has found that high school students in Manitoba are actually being taught that the science of climate change has not been settled yet!

If that is what they are being taught, it is disturbing, unacceptable and untrue!. The science is settled! There’s an overwhelming and longstanding consensus among the world’s top climatologists. We humans are altering the nature of our atmosphere by the amount of fossil fuels we're burning. This is trapping heat close to the earth’s surface. And, if we do nothing, the only home we have could morph into a place that’s not just inhospitable, but downright deadly! 

So, would Earth have been spared from the worst ravages of manmade climate change had this project not gone ahead? 

Of course not.

But are we doomed to a worst-case scenario if every jurisdiction in the world plowed ahead with "business-as-usual," as mine is doing? 

Absolutely!

P.S. I have written this in the spirit of the message we once tried to impart to the young. "Think globally. Act locally." Has that notion proven to be a mirage? A thing of the past? Please tell me it is not! l.p.

The more we carve up natural landscapes with roads and fields, the closer we’re pushing large predators like lions and wolves, toward extinction.

by Larry Powell

While the consequences of habitat loss have been known for some time, new research just published, underlines just how grave the situation has become. 

While this latest research is German, animals like the grey wolf face similar disruption in North America.

While this latest research is German, animals like the grey wolf face similar disruption in North America. 

It’s called “habitat fragmentation.” And, it’s been happening on such a large scale, it’s been hard to tell what aspects are the most destructive. That's because ecologists - at least 'til now - haven't been able to properly keep track of all wildlife within an entire eco-system when human developments confine them to smaller and more isolated patches of livable space.

Recent research contradicts a claim by the chemical giant, Bayer, that its newest bug-killer is safe for bees.

by Larry Powell

A honeybee colony in Manitoba. A PinP photo. It's brand name is "Sivanto," (generic name - flupyradifurone). It's an insecticide designed to kill a wide range of bugs which eat food crops such as soybeans. Bayer is registering it in many jurisdictions around the world.

After conducting various field studies, Bayer concludes, "Sivanto displayed a very promising safety profile." The company concedes, it works in ways similar to the neonicotinoids (a group of insecticides which has become notorious for its likely role in pollinator decline). Still, it finds, the product "can be considered safe to most beneficial insects, specifically pollinators."

But a team of scientists at the University of California, San Diego, reaches a different conclusion. In findings published earlier this year, the team gave a range of Sivanto doses to the bees, including ones they encounter in the field. By itself, the chemical did not appear to be harmful. But, when combined with the fungicide propiconazole (brand name "Banner Maxx"), widely-used by farmers, the harm was "greatly amplified." The bees either sickened or died, apparently because the fungicide weakened their ability to shake off the toxicity. It's not uncommon for pollinators to be subjected to a dizzying array of pesticides all at once, while foraging in the fields. It’s a process called "synergism," in which they can suffer harm they would not,  if  exposed to just a single one. The spokesperson for the team, Dr. Simone Tosi, tells PinP, she does not believe that regulations in the US require manufacturers to test for synergistic effects when they apply to have their products approved. But neither does she think that such regulations prohibit such testing. In a news release, her team says, "We believe this work is a step toward a better understanding of the risks that pesticides could pose to bees and the environment. Our results highlight the importance of assessing the effects pesticides have on the behaviour of animals, and demonstrate that synergism, seasonality and bee age are key factors that subtly change pesticide toxicity." They call for further studies to better assess the risks to pollinators. But at least one of those other studies has already been done. It, too, comes up with similarly negative conclusions. A team from three German universities has found that flupyradifurone binds to the brain receptors of honeybees, damaging their motor skills. Meanwhile, Bayer's marketing plans for its new product are ambitious. It promises to "develop, register and sell" Sivanto in many places across the world, including the US, Europe, Asia, Ghana and Brazil. While Canada isn't mentioned, specifically, there seems little doubt it will end up here, too. The company wants to see its product "in all major climatic zones allowing agriculture."

Last April, over three months ago, I e-mailed the federal Minister of Agriculture, Marie-Claude Bibeau, Canada's Pest Management Regulatory Agency, Manitoba's Minister of Health, Kelvin Goertzen and Manitoba’s Deputy Minister of Agriculture to ask them about this new research and whether Sivanto will be registered in Canada. 
Apart from a couple of automated responses, I have gotten no substantive answers.
