The good doctor is not wrong but it may already be irreversible. Every day we wait takes the world perilously closer to global extinction. Humans are really newcomers to this planet. Man seems to think that we have always been here and that population growth and misuse of the natural resources have no limit on a finite planet. Wrong.  Man may not always be here nor does he own this planet.  The warmer the planet the closer to extinction we get. CO2 emissions (a green house gas) roaring at 406-407 ppm and are accelerating at an unsustainably rapid pace .  These are NOAA's numbers from Moana Loa. This cake has been baked, the ingredients gathered and the product cooked. The party has started and could end in 40 or so years.  Take this doctors diagnosis very seriously and hope that there is medication to heal an ailing planet. We cannot pray ourselves out of this situation.  Thanks Dr. Chip... hope there is time left to make the difference.  More than serious....... fatal
