Climate of the last millennia
The role of forced and natural variability over the last millennia is investigated using simulations with the climate model LOVECLIM
General Circulation Models
, and proxy data
(which are indirect measures of past climate variability), using among other tools data assimilation
. A particular attention is paid to the spatial structure of the changes.
The contribution of atmospheric
circulation changes to the temperature (°C) difference between the Medieval Climate
Anomaly (MCA, 950-1250 AD) and the Little Ice Age (LIA, 1400-1700
AD) has been estimated from simulations performed
using LOVECLIM with data assimilation. For more details, see Goosse et al.
