Global Warming: Dire Prediction for the Year 3000
Even if humans stop producing excess carbon dioxide in 2100, the lingering
effects of global warming could span the next millennia. The results? By the
year 3000, global warming would be more than a hot topic - the West
Antarctic ice sheet could collapse, and global sea levels would rise by
about 13 feet (4 meters), according to a new study.
Using a computer model, researchers looked at two scenarios - an end to
humans' industrial carbon dioxide emissions by 2010 and by 2100 - stretched
out to the year 3000.
Even if humans were to stop emitting excess carbon dioxide - or if they
figured out a way to completely capture it - the effects of global warming
would continue to accumulate. That's because previously emitted carbon
dioxide lingers in the atmosphere and the oceans, unlike land, warm only
gradually, according to one of the study researchers, Shawn Marshall, an
associate professor of geography at the University of Calgary. |
