Lapdog,
Another unsubstantiated , scaring post "may have already passed the tipping point" beyond which global warming will accelerate uncontrollably.
Seriously!!
Do you really believe that and what date do you think we passed the tipping point?
Where is your global evidence not extreme models?
Was that tipping point1.5 DEg C as the IPCC postulated without any evidence or just any new scary number from models only?
