Periodic Reporting for period 4 - SPACE (Space-time structure of climate change)
Période du rapport: 2022-03-01 au 2023-08-31
By systematically analysing instrumental and paleo-records, we 1) determine the space-time structure of climate changes on annual to millennial time scales. This provides the prerequisite for mapping past climate changes and allow to confront climate models with robust estimates of climate variability across spatial scales; 2) provide a clearer separation of internal and external forced climate variability, by leveraging their distinct space-time structures; 3) examine the past relationship.
By the end of the project, we expect to have estimated the space-time structure of climate changes on annual to millennial time scales; a crucial step for mapping past climate changes. We further expect to leverage the distinct space-time structures of forced versus internal variability and disentangle the origins of climate variability during the Holocene, last millennium and last century. Finally, building on our first results and Individual Foraminifera Data we expect to know how seasonal to millennial climate variability has changed between colder and warmer climate states; test the ability of climate models to reproduce these changes and thus get a clearer picture how variability will change in a warmer future.
