The above quote is from the UK Met Office (UK Hadley Center for climate research)

The Met Office article continues with:

“The evidence is clear – the long-term trend is that global temperatures are rising, and humans are largely responsible for this rise.”

If you run a Google search using the title of Martin Durkin’s movie “The Great Global Warming Swindle”, my webpage ““The Great Global Warming Swindle” is itself a Fraud and a Swindle” (http://www.durangobill.com/Swindle_Swindle.html ) usually comes up on the first page of the results. Note that the page is recommended by MIT professor Carl Wunsch. It also had over 10,000 hits from the reference/link on Dilbert Blog. (Documentation for both is on the page.)

If “The Deniers” can’t learn via understanding the evidence, then they will learn the hard way that man-made “global warming” / “climate change” is real.
