How do the predicted climatic changes (IPCC, 2007) for the next century compare in
magnitude and rate to those that Earth has previously encountered? Are there comparable
intervals of rapid rates of temperature change, sea-level rise and levels of atmospheric
CO<sub>2</sub> that can be used as analogues to assess possible biotic responses to
future change? Or are we stepping into the great unknown? This perspective article
focuses on intervals in time in the fossil record when atmospheric CO<sub>2</sub>
concentrations increased up to 1200 ppmv, temperatures in mid- to high-latitudes increased
by greater than 4 ◦C within 60 years, and sea levels rose by up to 3 m higher than
present. For these intervals in time, case studies of past biotic responses are presented
to demonstrate the scale and impact of the magnitude and rate of such climate changes
on biodiversity. We argue that although the underlying mechanisms responsible for
these past changes in climate were very different (i.e. natural processes rather than
anthropogenic), the rates and magnitude of climate change are similar to those predicted
for the future and therefore potentially relevant to understanding future biotic response.
What emerges from these past records is evidence for rapid community turnover, migrations,
development of novel ecosystems and thresholds from one stable ecosystem state to
another, but there is very little evidence for broad-scale extinctions due to a warming
world. Based on this evidence from the fossil record, we make four recommendations
for future climate-change integrated conservation strategies. |
