Hi John,  Enjoyed your comments. Mauna Loa Observatory,  CO2 emissions @ 405 ppm.  Man has not existed when CO2 was higher than 350ppm.  Will events happen quickly?  No.  But they are moving quickly.  Therein lies the problems.  Heat cannot escape the earths atmosphere efficiently... warms the water and melts glacier's.  Warm water expands in volume (boil a kettle on your stove) and is helped along by steady and faster glacial melting. The dark oceans are warmer, acidic , absorbing more heat, and rising while the corals are dying from heat stroke often referred to as "bleaching".  Oceans retaining heat affects large weather events and ocean current patterns such as the "gulf stream" and el Niño's. Very complex.  Simple answer is ask the real Hawaiian fishermen about the conditions of the reefs.  The reefs are the blood of the planet. But no transfusion is on the way.  Looping effect....unstoppable.  I this anthropogenic (cause by man)?  The cake has already been baked.  Does it matter.
