Skeptic think tank now agree that the globe has warmed over the last 250 years and that carbon is the most likely reason likely reason for this.

THE Earth's land has warmed by 1.5 degrees Celsius in the past 250 years and ''humans are almost entirely the cause'', according to a scientific study set up to address climate sceptic concerns about whether human-induced global warming is occurring.
Richard Muller, a climate sceptic physicist who founded the Berkeley Earth Surface Temperature (BEST) project, said he was ''surprised'' by the findings. ''We were not expecting this, but as scientists, it is our duty to let the evidence change our minds.''
