Do read the link provided, and listen to the embedded videos. This summary hits the nail on the head for me.
""Noting the extremely small contribution to greenhouse gases from human activity (just 0.28%), the poor correlation between temperature and CO2, the non-causality between CO2 and temperature, the significant correlation of solar irradiance with temperature, recent global cooling, and unconvincing IPCC climate model predictions - then the alarmist reports from the IPCC appear questionable. And the fact that these reports are accepted by the UN, EU, WTO and national bureaucracies as the basis of long-term political and economic decisions has led many to cry 'conspiracy'. They claim that the flawed concept of anthropogenic warming is being used by climate change talks to raise taxes and to bring about one-world government. Western governments now charge a climate change levy (CCL) (tax) on taxable commodities such as electricity, natural gas, liquid petroleum gas (LPG), coal and coal products. This adds an unnecessary burden on industry, commerce and agriculture:""
