Noah's Heatstroke

In an article critiquing catastrophic plate tectonics, Answers in Creation argues that the amount of carbon released by ocean floor volcanism would have roasted Noah due to global warming. The study which they cite is unfortunately a 404, so I couldn't read it, but it would seem to me that, since there are currently proposals to sequester carbon at the bottom of the ocean, carbon released on the ocean floor would primarily stay there. I don't know if the missing article addresses carbon emissions from underwater volcanoes.

The carbon that reached the surface, however, would act as a heat-stabilizer. The newly warmed oceans would create enormous hurricanes, termed hypercanes, and the resulting cloud cover would increase the earth's albedo tremendously (from approximately 30% to as much as 90%). If the albedo increased to its maximum level, the earth would be absorbing one-seventh as much heat, so the greenhouse effect of the extra carbon would be vital for survival.

So where did the extra carbon go? Much of the pre-flood carbon is currently locked up in coal beds, natural gas, and oil. The new carbon was absorbed by new plant life after the flood. Once the weather started to normalize, the plants would begin absorbing carbon on a massive scale. Furthermore, the proposed post-Flood ice age would provide a longer-term source of increased albedo for the decades while the forests were reaching their maximum carbon levels.
