Sentences with phrase «during the interglacials caused»
«The hypothesis that the CO2 rise during the interglacials caused the temperature to rise requires an increase of about 6 °C per 30 % rise in CO2 as seen in the ice core record.

To answer this question, it is necessary to understand what has caused the shifts between ice ages and interglacials during this period.
Vetoretti and Peltier (2004) found that glacial inceptions can be caused either by a strong obliquity forcing or by a combination of eccentricity - precession forcing and low CO2 values, which is in line with results from Berger and Loutre (2001) who found that CO2 is important during times like the MIS - 11, when the insolation variations are too small to drive glacial - interglacial cycles.
-- Even during glacial and interglacial periods — mainly being caused by orbital changes — CO2 content in atmosphere have followed temperature changes.
Even if it has been warmer at times during the current and previous interglacials, showing that the forcing is unprecedented, rising and currently overwhelming natural variation can be seen of itself to be sufficient cause for alarm (that it be overwhelming is not quite what the IPCC report states but the more than half post 1950 claim is similar).
Misconception # 3 — During the interglacial periods changes in CO2 lag behind temperature rises, so are not the cause for warming
Similarly, Demezhko and Gornostaeva (2015) found that the heat energy change in the deep oceans during the climate transition from the last ice age to this current interglacial occurred «2 - 3 thousands of years» before the increases in surface temperature and CO2, and that «the increase of carbon dioxide may be a consequence [rather than a cause] of temperature increasing».
