"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.
