Then there is the widely known fact that there has been no statistically significant warming of the planet for more than 15 years despite 25 percent of all human CO2 emissions occurring during these years. This is accepted by no less than the UN Intergovernmental Panel on Climate Change and the UK Met Office. There is simply no scientific proof that our CO2 emissions are the cause of the slight warming that has occurred over the 300-year period since the peak of the Little Ice Age.
