Abstract
One area of consensus among forecasts of potential future climate changes resulting from anthropogenically increased levels of the so-called “greenhouse gases” is the amplification of these changes at higher latitudes, especially in the northern hemisphere and in winter (Houghton et al., 1990, 1992). Arctic and Boreal ecosystems thus may experience the greatest impacts of “global warming.” Palaeoenvironmental evidence, however, suggests that past global changes also may have been rapid in these regions (Dansgaard et al., 1989; GRIP Members, 1993). The palaeoecological record from high northern latitudes can provide invaluable evidence of the response of Arctic and Boreal ecosystems to these past changes; this evidence can help predict the future response of these ecosystems.
