More Dire Warnings About Global Warming

Our goal was to keep the planet from warming by 2 degrees centigrade.  We have already warmed by .8 degrees, and the amount of carbon that we have put in the atmosphere since will increase temperatures by another .8 degrees.  In other words, we are already at 1.6 degrees of warming. It looks as if the 2 degree increase goal is no longer possible.  One study suggests that we would have to reduce carbon emissions by 5.1% for 40 years in order to prevent temperatures rising above 2%.  We have not been able to reduce emissions by 5% in any year since WW ll.
