Back in 1985, Carl Sagan told Congress that continuing to burn fossil fuels will increase global temperature, cause climate change, melt glaciers and ice sheets, and cause sea level rise.

His solution: Fewer government subsidies for fossil fuels and use of renewable energy.

This may have influenced the script of the 1991 movie "Naked Gun 2 1/2" which beside all the jokes covers a lot of environmental issues.
Unfortunately the movie seems to be one of the more serious reactions to Sagan's speech.
