I'd look at the hot underwater vents just off the coast...may be the exit flows have increased, became more toxic, hotter?
I am sure these scientists have exhausted all possible alternative causes, especially the more obvious ones, before resorting to Global Warming. /s
The more this continues the more it feels like we are returning to a society as rendered in Gibson's Apocalypto where the "scientists" (the could predict eclipses) acted as priests and used their slightly greater knowledge to control the superstitious and ignorant locals. We are seeing science being attacked by a homocentric myth akin to pre-Kepler astronomy. Fortunately it will take only a few additional solar based empirical findings to blow this nonsense out of the water. Perhaps this time we can maintain the focus on the damage done by the hysteria - most of Africa is still plagues by the banning of DDT courtesy of Rachel Carson and the failure to adequately use the scientific tools we have to control diseases.
