As this visualization of smoke plume extents is provided by U.S. agencies, it doesn't show large wildfires outside the U.S. (Only satellite detections.)
I'm trying to integrate some public air quality data into my study. During a sanity check of the data I realized 3 of the measurement columns contain negative values! Does anyone have any idea if having negative value in such measurements is valid and how they should be interpreted?
Contacting the data manager is not as easy and might take me a week or two of emailing to get some answer. I wonder if #AirQuality folks here on fediverse have a quick answer.
This graphic shows the globally averaged temperature of every day since 1958
Because most of the earth's land mass is in the northern hemisphere, you can see the widening of the (northern) summer season, both starting earlier and ending later in the year
You can see the insane heat this past summer.
I think of this graph when I see how green the trees are where I live, in mid October.
"#Aerosols act like a “shade” to incoming sunlight, reflecting it back into space.
“We’ve been reducing [aerosol] emissions, which is good for #AirQuality, but it means now the #CarbonDioxide signal can punch through,” Professor Collins said."
Side note: Those aerosols are a form of #GeoEngineering. And #AirPollution causes the premature deaths of six million people worldwide every year. Is that kind of geo-engineering worth it?
Update on my partner, he's still positive (day 9 of positive tests, day 10 since symptoms, and 12 days since exposure). He's starting to feel a little better, cold-like symptoms remain and immense fatigue. He'll continue isolating until he's had two negative tests 48 hours apart.
In other news, today was an exciting day for me. All booked for my #Novavax COVID shot! I had to wait 90 days from my previous positive test in August, per epidemiological recommendations, and I have to drive 45 minutes to the nearest location that carries it, but I'm looking forward to the protection it'll offer before the next surge.
Stay #COVIDSMART:
🛌 Isolate when showing symptoms or testing [+]
😷 Wear N95s indoors

👐 Clean hands regularly
🪟 Open windows
🔲 Air purifiers & HEPA filters
🧪 Test (swabbing throat and nose on RAT) & report +C19 cases to @makemytestcount
@jeffjarvis “Nowadays, the air in Stockholm causes babies to have lung conditions and the elderly to die prematurely. We need to eliminate the harmful exhaust gases from petrol and diesel cars. That’s why we are introducing the most ambitious low-emission zone to date” #stockholm#airquality#climate#publichealth#waroncars#biketooter
Hey #Boulder#Denver#Colorado folks. That smoky smell today (Oct 10) is from a prescribed burn, not a #Wildfire. I was quite concerned until I figured it out.
And many someones in overlapping layers of responsibility ENABLED this infection.
This linguistic shift from the passive to active voice might seem irrelevant but, instead of just echoing the framing we see in the headlines — that Neil Gaiman got COVID-19— it’s time to own that somebody has infected Neil.
The passive voice has served a macabre purpose in this pandemic. The passive voice, by erasing the subject of the sentence, neatly obscures accountability, and with it our own role in unmitigated infections. Moreover, it has prevented us from identifying the layers of responsibility in enabling infections on a mass scale. This mental block is the first obstacle to advocating for effective mitigations and constructive solutions. It stops us from preventing infections. But that is changing now.
It is time to own the damage that we are causing by infecting others with COVID-19. I believe that we all know, deep inside, that we are causing harm. And many of us are suffering from the cognitive dissonance of pretending that we aren’t. Because, in a pandemic, this is serious and large-scale harm.
This harm that, according to estimates, has killed over 25 million people and disabled at least 65 million and counting. The sooner we face the harm we are causing by infecting other people, the less damage we will cause to ourselves, to our loved ones, to our community, to strangers on the other side of the world. And to people who entertain and inspire us, like speculative fiction author and TV creator Neil Gaiman. And inspiration is necessary when we are facing so many challenges. It’s that simple.
"The AirGradient DIY is an indoor air quality monitor kit enabling you to know if the air quality is healthy or not. It measures CO2, PM2.5, TVOCs, NOx, Temperature and Humidity. It’s easy to assemble, fully open-source and customizable, so you can extend it in whatever way you like."
“#Malaysia called on neighbour #Indonesia and a grouping of Southeast Asian nations to take action as #AirQuality worsens across the country due to fires in Indonesia, its environment minister told Reuters on Thursday (Oct 5).”
I can't tell you how excited I am reading this article! There are so many nondrivers out there, and we are part of every community. #WeekWithoutDriving can be an incredible tool to talk about the change we need for accessible communities!
