@environmentca does offer explanations for these numbers, but you have to go looking for them.
The most prevalent pollutant by mass is particulate matter less than 2.5 micrometers in diameter, roughly 50 times smaller than a grain of sand. Its prevalence is one reason health authorities issue air quality warnings using PM2.5 as the metric.
“There is another reason PM2.5 is used to make health recommendations: It defines the cutoff for particles that can travel deep into the lungs and cause the most damage.”
It’s for reasons like this that on smokey, polluted days, I don’t go to @environmentca’s websites to find out if we’re having a 9, 10, or 10+ lung damage day.
I tend to use aqicn.org, which uses data from local stations but shows the data better.
Here’s the image for #RedDeer from 7am this morning.
PM2.5 was 231 parts per million.
Other pollutants are also shown in PPM, along with other conditions like humidity and wind.
There’s even map to scroll on if you want to see a nearby station.
So the data is out there; it isn’t terribly difficult to understand; why is the government hiding the actual PPM values of pollutants like PM2.5 behind a simplified 1-10 scale instead of just telling you what the concentration of pollutants is?
…Because Conservatives don’t want you to have that information.
Okay, I don’t have a direct connection between the party of climate-denial and this specific 1-10 pollution scale, but stay with me and I’ll explain, briefly, why this messaging seems familiar.
The Harper Government—which both @erinotoole and @jkenney were a part of—was notorious for unravelling environmental protection, defunding science monitoring, & muzzling scientists.
One of their changes made was to rename the website where we go find out if it’ll rain tomorrow.
The word “environment” was stripped from the @environmentca site, and advertisements for the old “economic action plan” were plastered everywhere. #cdnpoli
#Conservatives corrupting census data during the was another example of this sort of thing. Without the vocabulary of up-to-date stats, quantifying & discussing the damage done by the Harper Government.
To get back to our thesis here: access to straightforward information about pressing matters in order to make informed decisions—from covid to climate change.
Putting up barriers to access that data can be harmful.
It can allow misinformation to capture the narrative. #cdnpoli
We already know that air pollution is extremely bad for your health.
Governments spent decades fighting tobacco lobbyists to reduce the rate of smoking in the general population.
We know that fossil fuel lobbyists are not above using misinformation…
So while it’s great that there are dozens (hundreds?) of air quality stations across the country, a 1-10 scale doesn’t match the international standard of just telling people the PPM of PM2.5 on a given day.
We’re almost done this thread about air pollution and how we think and talk about it.
I want to highlight a comment made by @crystal_suisho here about how learning other languages helps people be able to think about issues that affect society. 💯agree!
To add to @crystal_suisho’s comment, it is incredibly important to normalize not only the language surrounding important issues like the #ClimateCrisis, systemic racism, crony capitalism, and reconciliation for indigenous peoples.
Let’s end the thread here.
If you enjoyed reading this then you might also appreciate this thread on thinking critically about the media.
If you are concerned about the #ClimateCrisis, then you probably understand that the corporations who got rich destroying the planet aren’t willing to let go of their position or their power.
Here’s how the @NHL teams in #Alberta oppose taking action on climate change.
Now I want to see a sort of buddy-cop show with @aaronpaquette and @AndrewKnack going around #yeg helping people, & generally making the world a better place.
Every episode some Dark Money “Dr. Claw” type figure tries some evil scheme that gets thwarted…
@Isuckatpicking Want to know why rates are all going up almost in lockstep?
This will take a couple of tweets to explain.
In short: you’re paying for climate change.
@Isuckatpicking The insurance industry is sort-of pyramid shaped. Small brokers sell insurance from small insurance companies, but small insurance companies need insurance too. So they get insurance from bigger companies to limit their own risk, just in case.
@Isuckatpicking Follow that shape,& in essence, everyone’s insurance ends up being insured by a handful of very large players at the top who may as well only offer insurance to insurance companies.
This is the shape that this industry has evolved into over many decades. It was stable.
