During interglacial periods - we are enjoying one now, East Coast blizzards notwithstanding - the ice sheets retreat, the glaciers melt and sea level rises. The expansive but quickly melting ice sheets of Greenland, the North Pole and Antarctica are all that is left of our last glacial period, which reached its peak about 20,000 years...
...about 1 m higher than they are now - which suggests that global temperatures were at least as high, or higher than they are now, even though CO2 concentrations in the atmosphere were much lower then. The study also indicates that the sea level was changing rapidly around this time period, rising as much as 1 m the century before, as ice melted, and then falling afterward at around the same speed, as ice began to freeze once more. Rather than forming steadily and melting steadily, the process of glacier freezing and receding may be more more unstable, reflected in sudden...
