The Warming surface of our Planet

The Intergovernmental Panel on Climate Change having read and deliberated over the findings and analyses of a vast body of scientific opinion reached the conclusion that since 180 the surface of this planet has warmed by two degrees Celsius. I could put the figures differently and take a starting point of 1800, when the planet would have warmed by only 1.5 degrees. Since 1960 the surface warming has been by one degree.
