Well, there's nitrogen and carbon dioxide in the smoke, so I imagine all the plants are saying, "Ah, that's more like it".
It's funny this subject came up. All my plants have been standing tall the past few days. They seem to love this weather.

I find that hard to believe. But OK at least that makes some sense.
Most schools do not have AC in my town and many surrounding towns. Every time the issue comes up its defeated due to the immense cost

Did it ever occur to you they are unwilling to require their employees to be outside in this?

Once in a while it's not all about you.
You have to wonder if fear of lawsuits is one reason for various closings. Someone gets an asthma attack and dies or drives into a tree because they can't see and out come the lawyers.

It seems to me it's always about liability in this lawsuit crazed world.

Because it's stupid to spend ridiculous money to retrofit old buildings with A/C only to be NEEDED a few days a year. It should be defeated.
Well we could teach during the summer. Hey does summer school still exist or to we just pass kids who can't read onto the next grade these days? I suspect the latter.

At the same time, some people really do care about others and don't want to send them out to jobs where they will have a higher chance of getting sick or dying. It can wait a day or two.

It’s the same people who smoke or work in construction and never wear a mask. They all sing a different tune once the inevitable health problems start.
I'd guess the biggest issue is that authorities fear ERs getting overfilled with people having a respiratory or cardiac crisis, and a resulting shortage of oxygen and beds.

Conditions are slowly starting to improve, smoke-wise, and tomorrow should be a bit better than today, with the air quality alert being “orange” (unhealthy for sensitive groups) vs. today’s red (unhealthy for all) to purple (very unhealthy for all) and even hazardous in NYC and parts of NJ, depending on where one was. In fact, NYC's air quality index hit its highest level since the AQI was established in 1999 (377 - considered hazardous).

https://www.foxweather.com/weather-news/new-york-nyc-air-quality-levels-canadian-wildfire-smoke

See the graphic below for the AQI across our region as of 10 pm tonight and see the link below for the website that hosts this graphic and has tools for looking back at recent AQI levels and forward, based on modeling predictions for the next day. Tomorrow, winds will start to shift more towards the west, as the vertically stacked low to our NE retrogrades into New England, shifting the worst of the smoke westward and Friday’s air quality will be even better due to a further wind shift, combined with likely showers.

https://gispub.epa.gov/airnow/?show...orecastmonitors=forecasttomorrow&tab=forecast



Note that the high AQI levels are largely due to the PM2.5 levels, i.e., particulates < 2.5 microns, resulting from incomplete combustion of wood/cellulouse from the fires in Quebec. Prior to the passage of the Clean Air Act in 1970, many US cities had episodes of particulate pollution, from poorly controlled burning of fossil fuels in power plants, cars, incinerators, etc., similar to what we're seeing from these fires. Horrible smog (smoke/fog) outbreaks in the years prior to 1970 in many major US cities, including NYC (usually from a meteorological inversion trapping pollutants locally) were a major impetus for passage of the Clean Air Act, which has been a huge success for air quality and public health.
Air quality, while currently (1st graphic below) a bit better than yesterday’s hazardous levels (AQI’s > 300), is still in the unhealthy (AQI 150-200) to very unhealthy (AQI 200-300) range (outdoors), today, but should improve further for most throughout the day, today (link below to hourly smoke forecast), and more significantly by tomorrow (2nd graphic), with the forecast for moderate (AQI 51-100) to unhealthy-for-sensitive groups (101-150) tomorrow, followed by further improvement over the weekend, as the worst of the smoke continues to shift to the west, given the retrograding vertically stacked low pressure system now in Maine (was in Nova Scotia), combined with the low weakening and finally moving out to sea.

https://twitter.com/NWS.../status/1666743820342669313

Keep in mind, though, that the “dose” one receives of particulates is a function of the particulate concentration in the air multiplied by time of exposure in that environment, i.e., the dose is tiny, for example, walking to and from one’s car to go from indoor location to another indoor location, like a restaurant or shopping. The warnings about not being outdoors are generally for extended periods of time, which produce much greater particulate doses.

Air quality is still bad in Bergen County, per the DEP site. The air is a little bit clearer this morning and should get better through the day.

Actually, no, that's just precip related to localized sea breezes near the coast.

Edit: and you actually have a SWS covering this localized event...

The NY governor is telling ppl to stay inside if you don't have to go out. Has a familiar ring to it doesn't it ?
It's called being responsible and advocating for the general public health of the state's population. Is that concept too difficult for you to grasp? Do you actually not understand the science? Or do you simply like sounding like a complete moron?

Let's stop with the innuendo trying to link masks and requests to stay indoors with what went on under Covid restrictions. Both sides.

I could maybe see it "seeding" the atmosphere, giving something for the water particles to attach to and potentially causing a shower.

Conversely I think, by keeping the suns rays from reaching the ground, it would keep surface temps lower, the atmosphere more stable, and thus less conducive to thunderstorms.

Also, while it's obviously true that we've had wildfires forever, it's also clear that the level of wildfires has risen significantly over the last ~40 years, as per a 2016 study (discussed in the NOAA article linked below, along with many other studies linking wildfires to climate change) which showed that the number of large fires in the western US have doubled between 1984 and 2015.

https://www.noaa.gov/noaa-wildfire/wildfire-climate-connection

And while the current situation with the fires in eastern Canada aren't enough to establish any link to climate change (could be a one off - eastern Canada and the eastern US are generally much wetter than western Canada/US), it's absolutely true that eastern Canada has been historically warm and dry this spring.

It started off like that yesterday but by lunchtime it was a different story.
Definitely heading in that direction right now in NP, but still doesn't appear as bad as it was at this time yesterday. We'll see.

It has actually gotten a bit better in So. Bruns. since this morning. AQI was ~250 this morning and is now below 200.

This is the 3rd time in the last couple years that we've had smoke haze from far away fires here in NJ.

2nd time this year. When I first heard this haze was from Canada, I thought it was the Alberta fires, but nah, this is a different Canada wild fires.

Maybe it did happen prior, but I don't ever remember it.

I meant it's a one-off from the perspective of being this serious - the smoke levels and risks to the public are unprecedented for this region.

ON a normal day, I have a clear view of NYC skyline from my office in Metropark (Iselin). Can't see a single building today. Was not in the office yesterday.
Thanks, Canada.
