Record #183736:

Fossil-fuel hangover may stall ice ages / Fred Pearce.

Title: Fossil-fuel hangover may stall ice ages / Fred Pearce.
Author(s): Pearce, Fred.
Date: 2007.
In: New Scientist. (2007.), Vol. 195(2618) (2007)
Abstract: Reports use of mathematical models by Toby Tyrell of UK's National Oceanography Centre to examine long-term impact of CO₂ emissions on marine chemistry. Results suggest that as much as one tenth of CO₂ emitted today will remain in atmosphere for at least 100,000 years. Increasing acidity of oceans as more CO₂ is dissolved will allow more calcium carbonate from shells of marine organisms to dissolve and shift equilbrium so that oceans absorb less atmospheric CO₂. Simulations suggest that in IPCC's "business as usual" scenario, effect may prevent atmospheric CO₂ falling to that 560 ppm level that one model suggests may be necessary for next ice age to appear.
