"it is estimated that Earth as a whole cooled 3.0 ± 0.6 °C during the last glacial maximum (Hoffert and Covey 1992)"

Three degrees? How, then, is it possible that for instance Nordic Countries were covered in ice? If we now have summers of 20-30°C the drop should have been at least 30°C, not 3°C. Criticism, anyone? --Astikain (talk) 21:06, 30 October 2011 (UTC)
