Heat domes aren’t just another weather event — they’re a clear sign of our warming planet. When high-pressure systems get stuck due to atmospheric blocking and rising global temperatures, they trap intense heat for days or even weeks. This leads to record-breaking temperatures, from the Pacific Northwest to South Asia. To build resilience, we first need to understand the science behind how these heat domes form and grow. #HeatDome #ClimateCrisis #ExtremeWeather…

The science behind the heat dome — ‘a mosh pit’ of molecules

A mass of dangerous heat and humidity is spreading across the U.S. What exactly is it?

I have no doubt that #Edmonton could significantly reduce the urban #HeatIsland effect by remediating all communities presently without treed #boulevards between the concrete #sidewalks and the #asphalt streets to having such features.

I don't know if new neighbourhoods are still developed this way, but it is clear from observing where frontyard fencelines are set that there IS sufficient setback along many (all?) such neighbourhoods ro accomplish this without disturbing private property in the least.

Even prior to experiencing a #HeatDome and sustained #HeatWaves my neighbourhood was a nightmare of no-#shade heat when throughout the summers for any #pedestrian.

Sure, some homeowners plant trees but vanishingly few have a broad enough canopy to shade even the sidewalk. None cover the black asphalt.

How to prepare for "Heat Waves, Wet Bulb Temps and Wildfires" if you or someone around you is disabled:

Heat Waves, Wet Bulb Temps and Wildfires

Extreme weather events put disabled lives at risk. We are generally more susceptible to temperature fluctuations, power outages, supply chain issues and more. How can we protect one another?

Exactly so. We don't have summers anymore, we have #WildfireSeason.

#Edmonton has had a comparatively good summer so far this year (2025) with relatively mild bad-air days [still too rough for my lungs but most likely aren't openly suffering from here this summer] and excepting this week, no excessive streaks of ungodly heat.

I'm deeply grateful for this but after the past four years of #WildfireSmoke all summer, often accompanied by #ExtremeHeat or even a #HeatDome, I don't think I'll ever again look forward to #summer without extreme anxiety and fear. 😢

I hope you are taking care of your lungs during times like this! 🙂

Good morning Mastodonians! Another hot 'un, some puffy clouds in the sky...but we're supposed to have brutal thunderstorms today. BRING IT. Because it's in advance of a cold front and jeezo, I need a break from this heat. I want to be able to open a window at home. I want to not sweat to death while doing dishes. UGH.

Anyway, how're all my friends & followers this morning?
