'The United Nation's Intergovernmental Panel on Climate Change faces a fresh challenge with scientists casting doubt on its claim that the evidence for global warming is 'unequivocal'.In its most recent report, the panel said there was no doubt that temperatures are rising and that man is largely to blame.
But some researchers, including a former IPCC report author, say that widespread and systematic tampering of the data mean the case for global warming has been grossly overstated.
Hot debate: ice caps such as this one in Greenland are melting at an alarming rate but the evidence that the world is warming continues to attract doubt
The claim will further erode trust in the panel, which has been caught making unfounded claims several times in recent weeks.
These include using a student's essay and an article from a climbing magazine to make claims about reductions in ice on mountains around the world in a report used by governments around the world to set environmental policy.'
QUESTION: If the evidence for man-made global warming is so conclusive - why is there so much fabricated evidence out there?
