the easier way to explain this is...
the moon is red mainly due to the amount of dust ( or aerosol / particles suspended in the air) in the atmosphere of the Earth. When the moon is low (ie the light from the sun needs to pass the thru the Earth's atmosphere to hit the surface of the moon), the red color is picked up. remember that light can be spited into spectrum of colors? red being on one end is the reason why the color green wont be picked up, since green is in the middle of the spectrum.

the question is why wasn't it like this a few years back?

is it because of pollution, globam climate change, etc?

maybe u missed it hahaha
but the effect should have been intensified over the last couple years due to pollution... and the wild fire near us now must be contributed to the redness.
