Centre for Ice and Climate is a
centre of excellence at the Niels Bohr Institute, University of Copenhagen. The
main activities of the centre are drilling and analysis of ice cores with the
objective of understanding climate change in the past in order to improve our
understanding of present and future climate change.

The Centre has led the
international drilling projects GRIP, NGRIP, and NEEM that have led to
comprehensive investigations into the climate of the past 128,000 years,
corresponding to the most recent glacial-interglacial cycle. We also drill
ice cores in the Antarctic in cooperation with our partners, and in 2015 we
plan to drill through the Renland ice cap in East Greenland.
By performing measurements
on the ice cores, we have the opportunity to study how climate has changed,
and by measuring the air confined in the small bubbles of the ice, we reveal
changes in the composition of the past atmosphere. We use data from ice core
drillings as well as from radar observations to examine the ice sheet’s
anatomy and flow pattern, and by counting annual layers in the ice sheet we
can precisely date the ice.
