Global warming preceded by increasing carbon dioxide concentrations during the last deglaciation
International audience 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, howeve...
