The value of this information is illustrated by the results of a study published May 19 in the journal Geophysical Research Letters by Oster's group, working with colleagues from the Berkeley Geochronology Center, the Smithsonian Institution National Museum of Natural History and the University of Cambridge titled «Northeast Indian stalagmite records
Pacific decadal climate change: Implications for moisture transport and drought in India.»
While the CERES instruments are the most accurate broadband instruments yet flown, they are still not accurate enough to observe the subtle but
critical decadal climate change signals unless the instruments are overlapped for at least 6 months in orbit according to the GCOS climate - monitoring principles.13 For this reason it is crucial that measurement record gaps are avoided.
Back around 2007/8, two high - profile papers claimed to produce, for the first time, skilful predictions
of decadal climate change, based on new techniques of ocean state initialization in climate models.
Previously the time scale of the oceanic changes has been considered to be too long to be relevant to
decadal climate change.
«Predictions of
decadal climate change and variability, on the other hand, can be assessed in tests for past cases.
The uncertainties in the impacts of rising greenhouse gases on multiple systems are significant: the potential impact on ENSO or the overturning circulation in the North Atlantic, probable feedbacks on atmospheric composition (CO2, CH4, N2O, aerosols), the predictability of
decadal climate change, global climate sensitivity itself, and perhaps most importantly, what will happen to ice sheets and regional rainfall in a warming climate.
