atmospheric river

Capitalism is killing the planet

There is a myth about human beings that withstands all evidence. It’s that we always put our survival first. This is true of other species. When confronted by an impending threat, such as winter, they invest great resources into avoiding or withstanding it: migrating or hibernating, for example. Humans are a different matter.

When faced with an impending or chronic threat, such as climate or ecological breakdown, we seem to go out of our way to compromise our survival. We convince ourselves that it’s not so serious, or even that it isn’t happening. We double down on destruction, swapping our ordinary cars for SUVs, jetting to Oblivia on a long-haul flight, burning it all up in a final frenzy. In the back of our minds, there’s a voice whispering, “If it were really so serious, someone would stop us.” If we attend to these issues at all, we do so in ways that are petty, tokenistic, comically ill-matched to the scale of our predicament. It is impossible to discern, in our response to what we know, the primacy of our survival instinct.

Here is what we know. We know that our lives are entirely dependent on complex natural systems: the atmosphere, ocean currents, the soil, the planet’s webs of life. People who study complex systems have discovered that they behave in consistent ways. It doesn’t matter whether the system is a banking network, a nation state, a rainforest or an Antarctic ice shelf; its behaviour follows certain mathematical rules. In normal conditions, the system regulates itself, maintaining a state of equilibrium. It can absorb stress up to a certain point. But then it suddenly flips. It passes a tipping point, then falls into a new state of equilibrium, which is often impossible to reverse.

Human civilisation relies on current equilibrium states. But, all over the world, crucial systems appear to be approaching their tipping points. If one system crashes, it is likely to drag others down, triggering a cascade of chaos known as systemic environmental collapse. This is what happened during previous mass extinctions.

Atmospheric rivers of the kind that flooded British Columbia and renched California in recent weeks will become larger — and possibly more destructive — because of climate change, scientists said.

Columns in the atmosphere hundreds of miles long carry water vapour over oceans from the tropics to more temperate regions in amounts more than double the flow of the Amazon River, according to the American Meteorological Society.

These “rivers in the sky” are relatively common, with about 11 present on Earth at any time, according to NASA.

But warming air and seas around the globe causes conditions that scientists said will make them hold more moisture, causing extreme precipitation when they make landfall, often on the west coasts of North America, South America and Western Europe.

Because of climate change, atmospheric rivers are projected to become slightly less frequent, but more intense, according to a 2018 study led by researchers from NASA’s Jet Propulsion Laboratory.

“There may be fewer, but they are going to be lasting longer, and more intense,” Vicky Espinoza, an author of the NASA study who is now a graduate student at the University of California Merced, said.

Atmospheric rivers will become about 10% less frequent by the end of this century, but about 25% longer and wider, the study found. That will lead to nearly double the frequency of the most intense atmospheric river storms. (Continued: CTV)

From fire to ‘atmospheric river’: Why B.C. is trapped in a world of climate extremes

The past few months will not soon be forgotten in Merritt, B.C.

August 13, 2021

During a record-smashing heat wave that devastated British Columbia this past summer, its population of more than 5,000 people endured temperatures reaching 44.5 C. Soon after, it was racked by drought conditions and was the subject of an evacuation alert because of nearby forest fires. And on Monday, an evacuation order for the entire B.C. Interior city was issued in the face of epic flooding.

These climate-change-fuelled extreme weather events are connected: With intense heat comes wildfires, and with wildfires come changes to the soil and vegetation that can exacerbate the effects of heavy rainfall.

Similar scenes played out across B.C. Other communities that have suffered extreme flooding and landslides include Princeton, Abbotsford and Hope.

Bridges were washed out, and numerous highways were cut off in both directions by multiple mudslides and flooding. Some stranded motorists were evacuated by helicopter. At least one person has died.

It’s all because of heavy rainfall from a phenomenon known as an “atmospheric river.” They occur commonly throughout western North America, but this one has dumped atypical amounts of precipitation throughout the region.

According to preliminary Environment and Climate Change Canada data, 20 communities across B.C. experienced record rainfall for a Nov. 14, including Abbotsford, Langley, Nanaimo, Vancouver and Victoria. Though the final tallies aren’t in, for some communities those are historic records.

“Abbotsford and Hope had their wettest days in their record-keeping,” said Armel Castellan, a warning preparedness meteorologist with Environment Canada. “It’s certainly above a 50-year return period, and actually over 100 in many locations.” (A 1-in-100-year event has a 1-per-cent probability of occurring in any given year – that is, exceedingly rare.)

Recent research has shown a rising trend in atmospheric rivers making landfall on North America’s West Coast in recent decades. As the world continues to warm, they’re expected to become even more frequent and more intense.

“It’s so important to point out the role that climate change plays in these kinds of events,” said University of British Columbia climate scientist Simon Donner.

An atmospheric river is an intense and narrow band of moisture-laden air commonly associated with mid-pressure cyclones that bring heat and moisture from the tropics to the poles. They’re a bit like high-altitude air currents, such as the jet stream, except they’re concentrated in the first several hundred metres above the Earth’s surface.

They’re long (more than 2,000 kilometres), narrow (up to a few hundred kilometres wide) and can be up to a few kilometres deep. According to a Journal of Hydrometeorology study cited by the National Aeronautics and Space Administration, the passage of an atmospheric river over a coastal site takes on average 20 hours.

Please note…

This website contains satirical commentaries of current events going back several decades. Some readers may not share this sense of humour nor the opinions expressed by the artist. To understand editorial cartoons it is important to understand their effectiveness as a counterweight to power.
