Louise Sime

Biography

My research is primarily concerned with developing a better understanding changes in the ice sheets, sea ice, and climate in polar regions over the last 800 000 years. Much of my effort goes into understanding ice core observations of stable water isotopes by using climate models. Water isotopes (deuterium and oxygen-18) in ice are a key long-term record of past changes in the polar environmental and global climate. Water isotope enabled simulations, from climate models, help us understand how changes in ice sheets, sea ice, and climate imprint themselves on measurements from polar ice cores.
 

I have worked for the British Antarctic Survey since 2006. Before this, I had a two year stint as a senior research associate at UEA (2003-2006), and obtained a PhD from the University of Sheffield (in 2004). And before all that, I gained a BSc Hons degree from the University of Glasgow (in 1999).

Research interests

One of the key questions which has motivated my recent work is the question of how can we best use ice and marine core evidence from the Last Interglacial, 130 000 to 116 000 years ago, to help better predict likely polar change over the coming centuries.  Last Interglacial global temperature was quite similar to that predicted over the coming 50 years; but polar regions were substantially warmer than they are today. Reconstructing and modelling polar ice sheets and sea ice changes during the Last Interglacial provides a unique means to evaluate future predictions of critical changes in both polar climate and global sea level.
