Mother Nature creates many fires and particulates from volcanos etc which are going off everyday.
In the US, the majority of wildfires are caused by humans. In North America, South America, and Africa, humans cause wildfires at 6 times the rate of
Volcanoes cause more cooling than warming, because of the conversion of sulfuric dioxide to sulfuric acid. So if it were volcanoes that produced the
most emissions, we would be having a cooling, not a warming.
Humans produce 3 times the emissions of any natural source:
Recent estimates of the relative strength of the three important sources of volatile sulfur (SO2 from fossil fuel combustion ∼78 Tg S/yr, from
biomass burning ∼2 Tg S/yr, and from natural sources ∼25 Tg S/yr) suggest an over-whelming effect of the anthropogenic emissions for climate
PLUS........there are millions more cars than fireplaces so get off it, shutting down fireplaces doesn't make a damn difference.
what you fail to consider is that this is a local phenomenon, not a national one. The whole nation isn't shutting down fireplaces, just socal for a
day until the meterological event is over.
Again, it is not the amount being produced, it is WHAT is being produced. First, wood smoke particles are so small that they get into any house.
Unless you can build an air tight fortress, wood smoke gets into your house, or anyone's house.
Woodsmoke is far more dangerous than vehicle smoke. It is more dangerous than vehicle emissions, it is more dangerious than even cigarrettes.
1kg of burned wood produces more carcinogens than 27,000 cigarettes.
Because of its size, wood smoke is 7 times more likely to be inhaled than any other particles in the air.
And wood fuel users are 21% more likely to get cancer than any other fuel.
If inhaled second hand, wood smoke causes damage 40 times longer than cigarettes.
So when events form a dome that doesn't allow these dangerous particles to escape and everyone has to breath them in, THAT is why they put on a
Considering how dangerous it is, you should consider yourselves lucky it is not banned outright.
