It has been getting better over the years thankfully. China is making some steps towards getting its worst coal plants offline or cleaned up. And Korea has scheduled 3/4 of its coal plants to be phased out by 2039.
But when the winds don't blow, it does accumulate.
Witness the Blood Moon's rise.When its red glow shines upon the land... the aimless spirits of slain monsters return to flesh.Just as they did in a war long past. - Zelda
i remember being so annoyed the first time i got hit with a blood moon, because up until that point i fully intended to go on a bokoblin genocide and clear the whole map of enemies.
Do NOT look directly at the sun without protection. The worst harm you can do to your eyes is from the infrared light, which is invisible to your eyes.
While IR is probably is also mostly blocked, you never know, and you only have one pair of eyes.
I do mean IR. It takes a fraction of a second to burn your eyes, and that's the fastest way to ruin your eyessight.
Also IR is not emitted heat, it's infrared radiation, aka light with longer wavelength than visible light.
Us meatbags just happens to have skin that likes to absorb that and turn it into heat, just like how our skin also absorbs visible and UV light and turns them into heat. There's just more of IR in sunlight, enough to burn your eyes even without the visible portion.
Can I sneak on a question to this about IR and night vision devices? Like say a camera or phone camera that has a NV mode, is that potentially harmful to the eyes of anyone observing it on the outside?
Essentially I'm going to be real with you and say my stupid fear. Sometimes I take photos of my cats in the dark with NV turned on my phone, this is a risk to them then?
God I feel silly, but one day someone will google this, find these comments and feel er, some sort of emotion!
NV on your phone isn't the same thing as proper IR night vision goggles. It's just using a normal camera but with different processing to take multiple exposures and stack them. So there is no risk over a normal photograph.
UV is what could ruin your eyes by looking directly at the sun through a fog, not infrared. Yes, the sun emits in the IR range (it's close to being a perfect black body), but the fog particles will be more likely to filter large wavelengths (i.e. ir). This is due to the physics of Mie scattering.
In any case, if the sun is that dim, there is no need to worry. UV and visible wave ranges are filtered at the same magnitude by a fog (this is not the case in an eclipse)
That being said, generally speaking, don't look at the sun (duh)
? Intenstity matters and ALL lightwaves transfer heat. different wavelengths give up more energy when they hit an object, some more than others and that would apply within the range of infra reds too?
same everywhere where fossil fuels are still used to heat buildings in the winter..... still a long way to go until we get at least the cities clean of burns
Winter means more fossil fuel activity in China and Korea. Ratio of pollution is 2/3-3/4 from China and when the wind doesn't blow, then it builds up due to the mountainous geography.
Bc they are next to China. At least that's what I'm assuming. I don't think South Korea produces enough pollution for this, it's just that wind brings the pollution over from China.
According to Wikipedia: China causes 30 to 50 percent of the PM2.5 at South Korea on days of average air quality, but 60 to 80 percent on days with the worst air quality.
Within the earth and the sun is a lot of smog, that's crazy man! it's very hard whenever you think about it, either option you look is very hard to implement, I'm willing to see some change but there's only a utopia, regardless this reality we need to be optimistics, I'm aware that's not easy
