Facts are: - the concentrations of CO2 and other greenhouse gases (notably methane) in the atmosphere have increased steadily since the 19th. century and now are on such a high level never seen before for last million years. [1] - higher concentration of CO2 and other greenhouse gases lead to higher earth surface temperature - a shifting of the global average temperature of just a few kelvins can have devastating effect on our climate and environment. Just how much actually is in debate, not the effect itself.
