| Zusammenfassung |
| In the next century, the anthropogenic CO2 release is expected to deeply impact the Earth
climate system. This climate changes will result in a different wind and current distribution,
as well as a variation of the mass distribution at the Earth surface. Those changes will in
return affect the main geodetic observables: the Earth rotation, the gravity field and the shape
of the Earth. Our presentation will be dedicated to those changes, estimated from the outputs
of the Coupled Model Intercomparison Project (CMIP), in which a large number of Climate
models have been run under the hypothesis of a doubling concentration of CO2 in
a 70 years. We will analyse how and why the Earth rotation will be affected by
climate changes, and what will be its impact on the stability of the reference frame. |
