This is the title of a documentary that I'll be watching tonight (ch4 - 9.pm). I've always been very sceptical about the concept of global warming/climate change: is it really happening, and, if so, is it caused by human activities?
This is the preview in my TV guide:
Are carbon dioxide emissions caused by human activities really heating up the Earth, or could there be another explanation? This film challenges the consensus on global warming, with scientists arguing that the Earth's climate has always been changing, and that the effect of the sun's radiation may be to blame.
I can remember when I was at school in the 1970s everyone was worried about the approaching Ice Age...how soon things change.
