Read here. As the IPCC's quest for the holy grail of reduced CO2 has assumed the feeling of a Monty Python movie, the UN is now turning its focus on other human factors that likely affect global temperatures, including black soot. Besides changing the focus, this new UN study makes an amazing admission of CO2-mitigation futility:
"A fairly aggressive strategy to reduce carbon dioxide emissions under current reduction scenarios "does little to mitigate warming over the next 20 to 30 years," the study said. With carbon dioxide reductions alone, global temperatures are still projected to rise by more than 2 degrees Celsius by 2050 over pre-industrial levels."
It would appear the UN's 'killer CO2' has now officially become the new 'killer bunny'..."runaway, runaway, runaway!"...To where though? Hollywood? Perfect.
Although it has taken the UN several decades and hundreds of billions of wasted CO2 climate research funding, at least they are now turning their sights on human climate influences, such as black soot, that have a legitimate expectation of being controlled and reduced, without devastating the global economy.
