Briefly: The UN IPCC Report did not say "the world won't cool without chemtrails" It said: the world won't cool "except if net anthropogenic CO2 emissions were strongly negative over a sustained period." That means we would have to remove CO2 from the air. Some people consider that a form of geoengineering but it's nothing like Solar Radiation Management (SRM), which is what people are referring to when they talk about "chemtrails" for geoenginering. All the mentions of SRM in the IPCC report are about possible future use. In Depth: The claim that the UN says "the world won't cool without chemtrails" comes from this Daily Sheeple article by Melissa Melton, repeated in Before It's News http://www.thedailysheeple.com/un-the-world-wont-cool-without-chemtrails_092013 http://beforeitsnews.com/alternative/2013/09/un-the-world-wont-cool-without-chemtrails-2776026.html The actual New Scientist Article is at: http://www.newscientist.com/article...geoengineering-warns-report.html#.UkRoS2RwrMQ The mistake that Melton makes here is that the geoengineering referred to in the article is carbon removal, not Solar Radiation Management (SRM - blocking the sun in some way). When they say "except if net anthropogenic CO2 emissions were strongly negative over a sustained period", they simply mean that we need to remove more CO2 than we add. Nothing at all is mentioned about spraying things from planes, and it actually does matter if you buy that Hummer, because the entire argument here is about reducing the amount of CO2 in the atmosphere, which we have to do be reducing carbon emissions, and possibly by actually removing CO2 as well. And this quote: Is a quote from Fred Pearce of New Scientist, not from the IPCC. It's so obviously wrong, one can only concluded that Melissa Melton has deliberately created an inflammatory headline to drive traffic to her site - which is filled with the usual array of fear-based ads. Lastly, even if this was about SRM (which it is not), why would an article about doing SRM in the future indicate in any way that we are doing SRM now?
