'Something's changed': Summer 2023 is screaming climate change, scientists say

Floods, drought, fires, smoke and warm waters lapping three coasts

"Canadians?" joked the host. "I thought you'd smell more like smoke."

It's been that kind of season. Floods, drought, warm waters lapping three coasts — but mostly wildfire smoke from sea to sea and overseas. Yes, this is climate change, scientists say, and expect more weather weirdness to come.

"It's been a wild ride," said Danny Blair, co-director of the Prairie Climate Centre at the University of Winnipeg. "It's been a season and a year of extremes."

Drought is one example. Canada's a big place and it's always dry somewhere, but not like this.

Agriculture Canada's June 30 drought map shows most of the country was abnormally dry. Large stretches of the Prairies were under at least a moderate drought, pushing to extreme in southern Alberta.

In British Columbia, once the "wet coast," 28 out of 34 river basins were at the province's top two drought levels. Ranchers were selling cattle that they couldn't grow enough hay to feed, and low streamflows were threatening salmon runs.

And it's been hot. Although the east was generally normal, the west wasn't.

From May through July, Kelowna, B.C., experienced 36 days of weather more than 30 C. The normal count is 16. Norman Wells, not far from the Arctic Circle in the Northwest Territories, set a new record of 38 C on July 8.

Environment Canada senior climatologist Dave Phillips toted up the number of warm temperature records set this summer versus the number of cold records.

"If the climate was balanced, you'd have as many cold records as warm records," he said.

Nope. There were 372 new hot-temperature marks and 55 cold ones.

Fires and floods

Nor is the heat restricted to the land. Phillips said waters off all three Canadian coasts have never been warmer.

Hudson Bay is up to 3 C warmer. The Pacific coast is between 2 C and 4 C warmer. Both the Atlantic and Arctic coasts are up 5 C from average.

Then there were the floods — "so many floods," said Phillips.

On July 21, Halifax got three months worth of rain in 24 hours. Four people died in the floods, up to 600 had to evacuate their homes, and power cuts affected 80,000. Roads washed away and at least seven bridges were left needing major repair or replacement.

There were also fires that spread smoke across the continent and into Europe, where "Canadian wildfires" made headlines from the New York Times to Germany's nightly news.

With more than 13 million blackened hectares, it has been the worst wildfire season in North American history. All 13 provinces and territories have been affected, often at the same time.

Tens of thousands of people were forced from their homes, hundreds of houses were destroyed and four firefighters have been killed.

Over the years, cities such as Calgary and Edmonton have grown used to "smoke days."

This year, that unhappy club grew to include Ottawa (171 smoke hours), Montreal (100 smoke hours) and Toronto, which, on June 30, had the second-worst air quality in the world.

A 25-year-old Ontario man has become the second firefighter killed in British Columbia, and the fourth to die in Canada this season. Police say he was responding to the Donnie Creek wildfire Friday when his vehicle rolled over a sharp drop in the road.

Wikipedia already has an entry for "2023 Canadian Wildfires." The fire season is barely half over.

It's not just a year of particularly wild natural variability, Blair said.

"Canada experiences a remarkable amount of variability from year to year," he said. "It's not unusual for us to have dry weather or hot weather.

"But the frequency of it and the severity of it and the coinciding of it with enormous extremes of weather in the U.S. and across the world is suggesting to a lot of people that something's changed."

'Way outside the line of natural variability'

World Weather Attribution, a group in the United Kingdom that estimates the contribution of climate change to individual weather events, has already said the U.S. and European heat waves this summer would have been "virtually impossible" without it. Its analysis of Canada's wildfires is expected later this fall.

"I have no doubt the conclusion is going to be that these events are way outside the line of natural variability," Blair said.

"This is screaming climate change. It's the very thing we've been talking about for years."

Get used to it, at least for the next few months.

"Our models for August are showing no areas of Canada that are cooler than normal," said Phillips.

If cooler is what you want, you'll have to go to the east coast of Baffin Island. Everywhere else is showing at least normal heat, which is expected to stick around.

It'll last well into September, for better or worse, Phillips said.

"What you see is what you're going to continue to get."

Do you really thinks JT's beloved Carbon Tax Is gonna stop Mother Nature from doing her thing?

This supervolcano in Italy last erupted in 1538. Is it about to blow again?

The volcano last erupted in 1538.

By Rebecca Ann Hughes

Published on 16/06/2023

"Some 30,000 years ago, the volcano is thought to have contributed to the extinction of the Neanderthal man.

In 1538, the volcano erupted over a period of eight days, shooting out enough lava, rocks and clouds of ash to form a new mountain. In the 1980s, there was another surge in activity which resulted in the
evacuation of 40,000 nearby inhabitants.

Since then, the supervolcano has been relatively quiet.

Now, however, a study by researchers at University College London (UCL) and the National Institute of Geophysics and Volcanology (INGV) in Italy has found that a reawakening could be imminent.

“We’re not saying there will be an eruption, we are saying that the conditions for an eruption are more favourable,” lead author Christopher Kilburn from UCL told AFP.

One reason is that tens of thousands of minor earthquakes that have occurred since the 1950s have weakened the hollow at the summit of the volcano known as the caldera.

Will the Campi Flegrei volcano erupt?

In the study, published in the journal Nature on Friday, the scientists reported that “parts of the volcano had been stretched nearly to breaking point”.

Since 2019, the number of small tremors has been rising, piling pressure on the volcano’s crust. In April, 600 of these vibrations were recorded.

Surrounding ground level has also risen. The seaside town of Pozzuoli has been raised by almost four metres since the 1950s, according to the report."

Climate change is a major topic with Canadians this summer. A lot of eye opening events. Safe to say going forward that any political party not having a strong stance on climate change will be dismissed quickly.

Not having carbon pricing for dumping into the atmosphere would be like allowing people and companies to dump into the oceans unchecked . Elon Musk. Right now, it’s the only effective way to deter the dumping

Opec produces 80 % .

The rest of the private companies 14%

Yet Canadian oil is the only oil attacked inveromentlists.

Ralph Eddy
Facts.

When u add up all the carbon foot prints of all the people in Canada and the oil and gas industry etc.

Canada only produces a very small 1.5 % of all the GHG on Earth.

If man made GHG is the problem there is nothing we can do in Canada.

We don't produce enough to be able to reduce enough to matter.

That is a science fact


Bill Gardiner
Reply to Ralph Eddy
That is why it’s a global initiative. The world is transitioning from fossil fuels, not just Canada.
