The combination of the two methods is an important way to understand paleoclimate change and long-term water cycle mechanisms.

It is the simultaneity of these properties recorded in the ice that makes ice cores such a powerful tool in paleoclimate research.

In 2007, Loehle published a paleoclimate reconstruction which reconstructed temperatures over the last 2, 000 years, in " Energy & Environment ".
29.
It is unclear whether continental ice sheets existed during the Late Cretaceous because of conflicting ocean temperature estimates and the failure of circulation models to simulate paleoclimate data.
