Read here. Death. Destruction. Devastation. North America and the United States have experienced all sorts of severe weather events that have caused significant mayhem. As the figure below indicates, many of the 'worst-of-the-worst' weather incidents took place decades before the infamous "global warming" climate change of the last two decades.
It now appears that low atmospheric CO2 levels cause extreme climate change, based on the actual "causation" evidence. Many experts are now wondering if the UN-IPCC's and MIT-favored precautionary principle should be invoked globally in order to avoid future low CO2 levels. It would require pumping vast amounts of CO2 into atmosphere to mitigate low-CO2 climate change weather events. ;-)
