"
Inclement weather" means
unpleasant weather, which is stormy, rainy, or snowy weather. However, the phrase inclimate weather often is mistakenly used when
the speaker really means "inclement" weather.
Amos: This is the coldest summer we have had on record. We need to do something about anthropogenic
climate change.
Ignore Amos: Dude, there ain't no
global warming! It's colder than usual this week, and don't you remember that inclimate weather we had this winter? That was cold, too!
Amos: Anthropogenic climate change does not mean just
global warming. It also includes unseasonably cooler weather due to the melting of the polar ice caps. Furthermore, cold weather in the winter is not inclimate weather. I think "inclement weather" is what you meant to say.
