They continue to lie and give away your money.  Recently the UN IPCC published more scary statements about the increasing CO2 trend and predicted future global warming that they say will result.  Their predictions included dire warnings about damage to the food supply in the near future.  President Obama, his science advisor John Holdren, the EPA, the Department of Interior, SOS John Kerry and many others have echoed the UN warnings and they have spent hundreds of billions in US dollars under the banner of reducing CO2, and they have caused mines and power plants to shut down.  But none of these people provide real world data to validate their claimed climate crisis, the money is being spread around to cronies and many of these crony companies are going bankrupt.  

What if CO2 continues rising and the planet begins warming again and precipitation declines as the UN IPCC predicts?  How might this warmer, drier, CO2-enriched future world affect global wheat production? According to the authors of this 2014 study, which is a meta-analysis of 90 scientific papers, the outlook for the future of wheat production is positive thanks to the projected concurrent rise in atmospheric CO2.  “…the effects of high CO2 concentrations (>640 ppm) outweighed the effects of increasing temperature (up to +2°C) and moderate declines in precipitation (up to -20%), leading to increasing yields.”  In concluding their study, Wilcox and Makowski say their results “provide an overall positive outlook for the future of wheat production.”  http://www.co2science.org/articles/V17/N16/B2.php
