アブストラクトはこれ
The covariation of carbon dioxide (CO2) concentration and temperature
in Antarctic ice-core records suggests a close link between CO2 and climate during the Pleistocene ice ages.
The role and relative importance of CO2 in producing these climate changes remains unclear,
however, in part because the ice-core deuterium record reflects local rather than global temperature.
Here we construct a record of global surface temperature from 80 proxy records and show
that temperature is correlated with and generally lags CO2 during the last (that is, the most recent) deglaciation.
Differences between the respective temperature changes of the Northern Hemisphere and Southern Hemisphere parallel variations
in the strength of the Atlantic meridional overturning circulation recorded in marine sediments.
These observations, together with transient global climate model simulations, support the conclusion
that an antiphased hemispheric temperature response to ocean circulation changes superimposed on
globally in-phase warming driven by increasing CO2 concentrations is an explanation for much of the temperature change
at the end of the most recent ice age.
