Global Climate Change: The Immediate Past

Chapter

Abstract

The climate changes during the last deglaciation were very large. Conditions for the growth of trees often changed faster than the plants could migrate resulting in forest types with no modern analog. Ice cores from Greenland show sudden short-term temperature changes called ‘Dansgaard-Oeschger events’ that affected the northern North Atlantic. Massive iceberg discharges into the North Atlantic through the Labrador Sea, ‘Heinrich events’ occurred periodically. Attempts to reconstruct the Earth’s temperature history over the past two millennia that showed the warming taking place in the last century were greeted with skepticism by politicians, as exemplified by the ‘hockey stick controversy’ which bore uncanny resemblance to the trial of Galileo Galilei.
