Transient climate simulations of the deglaciation 21-9 thousand years before present (version 1) - PMIP4 Core experiment design and boundary conditions
Ruza F. Ivanovic is funded by a NERC Independent Research Fellowship (no. NE/K008536/1). The last deglaciation, which marked the transition between the last glacial and present 23 interglacial periods, was punctuated by a series of rapid (centennial and decadal) climate 24 changes. Numerical climate...

Ruza F. Ivanovic is funded by a NERC Independent Research Fellowship (no. NE/K008536/1). The last deglaciation, which marked the transition between the last glacial and present 23 interglacial periods, was punctuated by a series of rapid (centennial and decadal) climate 24 changes. Numerical climate models are useful for investigating mechanisms that underpin the climate change events, especially now that some of the complex models can be run for multiple millennia. We have set up a Paleoclimate Modelling Intercomparison Project (PMIP) working group to coordinate efforts to run transient simulations of the last deglaciation, and to facilitate the dissemination of expertise between modellers and those engaged with reconstructing the climate of the last 21 thousand years.
