ESD Ideas: Why are glaciations slower than deglaciations?

Christine Ramadhin and Chuixiang Yi

Data sets

Interglacial and glacial variability from the last 800 ka in marine, ice and terrestrial archives (http://www.clim-past.net/7/361/2011/cp-7-361-2011-supplement.zip) N. Lang and E. W. Wolff https://doi.org/10.5194/cp-7-361-2011

Short summary

Here we explore ancient climate transitions from warm periods to ice ages and from ice ages to warm periods of the last 400 000 years. The changeovers from warm to ice age conditions are slower than those from ice age to warm conditions. We propose the presence of strong negative sea–ice feedbacks may be responsible for slowing the transition from warm to full ice age conditions. By improving understanding of past abrupt changes, we may have improved knowledge of future system behavior.
