"Local" changes. A dirty river pollutes the shores and downstream but it doesn't change the global (worldwide) climate. LA smog effects that area but it doesn't change the climate in New York. An oil spill in the North Pacific doesn't change the climate of Germany.
I thought you didn't want God or religion discussed in this thread?
"Temporary" means no effect on weather or climate patterns of activity, only on present conditions. Today's belching Buick in Baltimore isn't going to cause snow next month in Miami.
