Well while everyone has their sights on global warming today on Earth Day 2017 and argue humans are the cause of global warming, let me state a no argument fact we face of equal if not more of importance. Humans can and possess the ability to cool our beloved Mother Earth  globally, Nuclear Winter ring a bell anyone? How many minutes left on the "Doomsday Clock"  on this Earth Day celebration.

As for global warming. 

  Humans do not cause global warming we contribute! Therefore we are limited to just effecting what we are contributing. We can not reverse it, only slow it' s progress. Where as for Nuclear Winter when it begins it is a bend over and kiss your fantails good bye of the last order.
