I've been producing documentaries on global warming for 20 years and have seen the early warnings of extreme weather events come true.

The most frightening interview I've ever done was with Dr. Lonnie Thompson of The Ohio State University on the subject of global warming.

Global warming isn't a prediction. It is happening.

What we know now as extreme heat will be considered normal if global warming continues.

Esso has been the main one in America spreading the disinformation that there is no global warming problem.

How lazy are we getting?! Just throw it in the recycling bin already!
