Our weather is getting worse each year if you haven't noticed. Have you ever thought where the emissions from your car go? Those of you who think they just disappear after some time, think again. Rather they are trapped in our atmosphere and keep heat close to the surface of earth, contributing to global warming. As you can see, in recent years, the number of natural disasters such as flooding, wildfires and serious earthquakes is on the rise.

Are there any mistakes?
Thanks.

Comma after "worse each year," to set off the smart remark.

I'd try to avoid the agreement issue with "number." Of course it's correct, but it's sort of unpleasant. If you removed "the number of ," then "number" would be understood. (That would probably be considered incorrect, although it's quite common.) It's okay to leave it as is, if you can't think of another way. - A.

Are you saying the above is correct?
New2grammarNatural disasters, such as flooding, wildfires and serious earthquakes, are on the rise.

As Yoong Liat says.

My point was that after all those plurals, the ear likes to hear a plural verb. Being so far away from "number," the ear forgets that a singular verb is being asked for. "Disasters" is plural, so the problem disappears.

But I fear there'll be objections to the sentence in this form, since one may ask, "What does it mean for a disaster to rise?" Technically, it's the number that rises.

If you say "Smallpox is on the rise again," you probably mean the number of cases, but you could also mean "the threat of smalpox" is on the rise.
