Edmonton experiences second hottest, third driest July on record: Environment Canada data

If you find yourself thinking this July feels hotter than normal you are not alone, and now there’s some data to back up your claim.

According to preliminary data — up to July 28 — from Environment and Climate Change Canada (ECCC), the Edmonton area saw an average temperature of 20.1 C for the month of July, including highs of 35.2 C on July 1 and 32.5 C on July 10, making July the second warmest on record. With just estimated total precipitation of 21.1 mm, July was also the third driest July on record.

he historical data goes back 140 years, said ECCC meteorologist Justin Shelley on Saturday.

“The Edmonton region has gotten more precipitation than other parts of the Prairies, too, surprisingly,” said Shelley. “It’s been a pretty dry summer for all of Western Canada, really.”

The national weather agency issued another heat warning for Edmonton and the surrounding area Saturday morning as forecasters are calling for long-weekend highs ranging from 29-35 C, and lows in between 14-20 C.

Climate Change and the Muddled “Moveable Middle”

Over seventy five percent (75%) of Canadians are truly worried about climate change and want a climate action agenda that is more bold and ambitious. Unfortunately, most supporters—45% of the Canadian public—fall into the muddled “moveable middle” where the demand for action is much less than the concern over climate.

Key take-home points from a March 2021 presentation on Canadians’ opinions on the climate crisis from Climate Access were:
  • Most Canadians agree global warming is a crisis
  • But 89% think we’re average or better than most countries
  • Most Canadians can’t name a climate policy
  • Sadly, less than 50% of Canadians can correctly name a GHG too
  • Happily, most Canadians see the COVID crisis as a good time to act
  • Importantly, most (45%) supporters fall into a muddled “moveable middle” and we should consider them the most when communicating

Wildfires in Canada are creating their own weather systems, experts say

Abundant fuel, heat, wind have caused pyrocumulonimbus firestorms that have been tracked from B.C. to Ontario

A combination of intense heat and drought conditions is causing wildfires in Western Canada to generate their own weather systems, experts say.

Michael Fromm, a meteorologist with the United States Naval Research Laboratory, said the phenomenon is known as a pyrocumulonimbus firestorm and has been tracked this year in British Columbia, Alberta, Saskatchewan, Manitoba and Ontario.

Scientists have been tracking the storms since May. The first one was seen this season in Manitoba, Fromm said in an interview Monday.

The Village of Lytton in B.C. saw firestorms on two successive days in late June, he said.

“It was probably the single largest pyrocumulonimbus storm of the year so far,” he added.

“In fact, we’re still tracking the smoke plume from that storm as it’s travelling around the world and it’s about to kind of come full circle back over the U.S. and Canada.”

‘Perfect’ firestorm conditions in B.C.

An abundance of fuel, heat and wind create perfect conditions for the firestorms.

Lytton hit a Canadian temperature record of 49.6 C the day before a wildfire erupted there on June 30, destroying much of the community.

“When you get all those three things together, you get the perfect triple that we call fire weather,” Fromm said. “So, hot, dry and windy.”

Simon Donner, a climate scientist from the University of British Columbia’s geography department, said the storms also generate lightning that cause more fires.

“The fire creates the storm, and then the storm creates lightning, which can cause more fires,” he said.

“That runaway feedback is the dangerous part.”

Warming Planet Means 83 Million Face Death From Heat This Century

A population equivalent to that of Germany — 83 million people — could be killed this century because of rising temperatures caused by greenhouse-gas emissions, according to a new study that might influence how markets price carbon pollution.

The research from Columbia University’s Earth Institute introduces a new metric to help companies and governments assess damages wrought by climate change. Accounting for the “mortality cost of carbon” could give polluters new reasons to clean up by dramatically raising the cost of emissions.

“Based on the decisions made by individuals, businesses or governments, this tells you how many lives will be lost or saved,” said Columbia’s Daniel Bressler, whose research was published Thursday in the journal Nature Communications. “It quantifies the mortality impact of those decisions” by reducing questions down “to a more personal, understandable level.”

Adapting models developed by Yale climate economist and Nobel Prize winner William Nordhaus, Bressler calculated the number of direct heat deaths that will be caused by current global-warming trajectories. His calculations don’t include the number of people who might die from rising seas, superstorms, crop failures or changing disease patterns affected by atmospheric warming. That means that the estimated deaths — which approximates the number of people killed in World War 2 — could still be a “vast underestimate,” Bressler said.
