Read here. In a previous post, we discussed the World Climate Report analysis of global warming since 1950. As the latest research has discovered, the 2007 IPCC report's attribution of 100% of global warming to CO2 (greenhouse gases) is drastically wrong. The newest and best research indicates multiple factors are responsible for the 0.702°C increase of global temperatures since 1950.
Below, is a visual representation of the latest scientific estimates of contribution to global warming. Each factor/influence to global warming is identified, including estimated contributions (%). Note that we've added a natural component to Bar #3, which only represents 5% of warming since 1950. Prior to 1950, 100% of the global warming is considered to be natural by most scientists. In addition, Bar #3 includes a 5% factor for 'bogus temperature adjustments' by the major climate agencies due to their desire to overstate global warming. Finally, Bar #3 'Land-Use' percentage has been increased by 5% for an enhanced UHI effect as latest research is showing it to be a strong component of global warming.
As climate research advances, as more scientific evidence is gathered and is analyzed, the GHG contribution to global warming will again be reduced. Within three years, it is highly probable that scientists will reduce the GHG warming contribution to less than 10%. (click on image to enlarge)
