The Glaciers of Greenland

Even in ice-cold Greenland, Holocene temperatures followed much the same temporal pattern observed in other parts of the world, as did the advance and retreat modes of its local glaciers, with maximum glacier extensions occurring during the coldest period of the current interglacial (the Little Ice Age). As a result, it was only to be expected that once the millennial-scale oscillation of temperature bottomed out and began to rise again, the result would be a significant warming and recession of local glaciers, irrespective of anything the air's CO2 content might do concurrently, as the climate rebounded towards its more normal Holocene mid-range. In other words, Greenland would likely have experienced the same degree of warming and glacial recession that it experienced over the course of the 20th century even if the atmosphere's CO2 concentration had remained at the same low value it had maintained throughout most of the Holocene to that point in time.
