"Recent polls have shown that belief in global warming is waning.
Last month, Cardiff University found an increasing number of Britons are becoming more sceptical about climate change.
It found that 29 per cent believe the threat has been exaggerated - compared to just 15 per cent five years ago. One in five are hardened sceptics who believe manmade global warming is a myth.
In the U.S. polls have shown that nearly half of Americans no longer believe in global warming.
Only 57 per cent of Americans agree that world temperatures are rising, while just one in three believes humans are causing climate change, the survey carried out by the Pew Research Centre based in Washington showed."
90% argumenten voor + 10% argumenten tegen = twijfel = "we weten het niet" = "het kan net zo wel waar zijn, als niet waar" = "laten we voorlopig nog maar niks doen en afwachten".
