Sentences with phrase «triggering past ice ages»

The resulting lower atmospheric CO2, the argument goes, would mean lower temperatures, suggesting that the mechanism was at least partially responsible for triggering past ice ages.

Not exact matches

For example, the ice age — interglacial cycles that we have been locked in for the past few million years seem to be triggered by subtle changes in the earth's orbit around the sun and in its axis of rotation (the Milankovitch cycles) that then cause ice sheets to slowly build up (or melt away)... which changes the albedo (reflectance) of the earth amplifying this effect.
