2°C is 3.6°F. That is a huge amount of warming. It is absurd for Marburger to claim that that amount of increase "is not actually linked to regional events that affect people's lives." Simply absurd. It is one of the most unscientific statements I have read in a long time.
In its April report, the IPCC outlined a range of environmental impacts that could transpire if temperatures rise 1.8 to 3.6 degrees Fahrenheit above 1980 levels. These include placing between 20 and 30 percent of all species "at increasing risk of extinction" damaging most coral reefs; and "increased morbidity and mortality from heat waves, floods and droughts."Marburger said, "you could have emerging disasters long before you get to two degrees. . . . There is no scientific criterion for establishing numbers like that."
There is no scientific criterion for establishing any number -- such establishment is a question of values, not of science. Marburger looks foolish for even implying otherwise.
In 50 years, the world is going to look back on the climate criminals of the turn of the century. Marburger just established himself as one.
