|a The severity of damaging human-induced climate change depends
not only on the magnitude of the change but also on the potential
for irreversibility. This paper shows that the climate change that
takes place due to increases in carbon dioxide concentration is
largely irreversible for 1,000 years after emissions stop. Following
cessation of emissions, removal of atmospheric carbon dioxide
decreases radiative forcing, but is largely compensated by slower
loss of heat to the ocean, so that atmospheric temperatures do not
drop significantly for at least 1,000 years. Among illustrative
irreversible impacts that should be expected if atmospheric carbon
dioxide concentrations increase from current levels near 385 parts
per million by volume (ppmv) to a peak of 450–600 ppmv over the
coming century are irreversible dry-season rainfall reductions in
several regions comparable to those of the ‘‘dust bowl’’ era and
inexorable sea level rise. Thermal expansion of the warming ocean
provides a conservative lower limit to irreversible global average
sea level rise of at least 0.4 –1.0 m if 21st century CO2 concentrations
exceed 600 ppmv and 0.6 –1.9 m for peak CO2 concentrations
exceeding [approximately]1,000 ppmv. Additional contributions from glaciers
and ice sheet contributions to future sea level rise are uncertain but
may equal or exceed several meters over the next millennium or
longer. |
