Weather is crap
No, seriously - a study of the atmosphere shows that there all kinds of crap in the air.
Not only that, but all this crap in the atmosphere could actually affect the weather.
A global study of the atmosphere found that for about 1 in every 4 bits of solid particle they found high in the atmsophere, was something from an animal or plant - like bits of fur, skin, algae, bacteria, or pollen, for example.
It’s now being estimated that around a billion tons of this gets into the atmosphere, every year.
Because there’s so much of this shit up in the atmosphere, it means that it must play an active role in weather formation, such as helping rain clouds form.
So now when it rains, you might be more thankful for an umbrella.
