What is the cotton-like pollen that flies a lot these days?

I was wondering what cotton is flying a lot these days.

It looks like pollen, but what kind is it?

At first, I thought it was dandelion, but I wonder if there are that many dandelion puffs.

There were more dandelions than I thought
Of course, there's a lot of cotton

I think it's a poplar tree or a willow tree
