Once Greenland's ice sheet gains enough lubrication, it will slide into the north atlantic and disrupt the gulf stream. Odds are, this disruption will have major implications on sea life, but on the other hand, the artic ice sheet will come back.
Im pretty sure ive read that when Panama was open water, there was no arctic ice sheet, and when it closed, it caused major oceanic disruptions.
Global warming and climate change are undeniable; its man's impact that seems to be debated.
I for one think mans ability to stop climate change is laughable. Its awfully ostentatious to think we can make an impact. If a volcano or two goes 'Krakatoa' or worse, what will we do about all those greenhouse gases being given off?
The only way we actually stop carbon is eliminating coal, oil, and natural gas. This could only be accomplished with nuclear energy. Most environmentalists dislike nuclear energy, go figure.
FWIW nuclear fusion power
plants seem pretty safe.
