Global warming is real

Telegraph
""The planet has been warming," says a new study of temperature records, conducted by Berkeley professor Richard Muller. I wonder what he'll be telling us next: that night follows day? That water is wet? That great white sharks have nasty pointy teeth? That sheep go "baaaa"?

No, the only surprising part of the results of the Berkeley Earth Surface Temperature Project is the good professor's chutzpah in trying to present them as new or surprising – let alone any kind of blow to the people he calls "skeptics" (or, when speaking to his friends at the Guardian, "deniers").

....... It has been a truth long acknowledged by climate sceptics, deniers and realists of every conceivable hue that since the mid-19th century, the planet has been on a warming trend – emerging, as it has been, from a widely known phenomenon known as the Little Ice Age. A period which in turn was preceded by the even better known Medieval Warming Period.

This is why the standard rebuttal to the term "climate change denier" is: "But I don't deny that climate changes. I recognise that it has done so since the dawn of time. What I question is not the process of climate change, but what causes is it, whether it represents a problem and whether there's anything we can do about it other than sensible mitigation."
