All data sources agree that positive IOD events are becoming stronger and occur more often and that the mean-state of the Indian Ocean is moving towards a more positive IOD-like state due to enhanced warming in the west compared to the east.

CLEX researchers and colleagues find Australia's infrastructure would be unable to deal with past flood events and thus is very likely to be unable to mitigate future flooding under climate change.
New research confirms the long-term cooling over Antarctica during the last millennium and the delayed onset of anthropogenic warming are found in simulations that assimilate palaeoclimate data. This is not evident in simulations without data assimilation.
This study employs a new statistical approach to reconstructing ENSO which enables researchers to identify times in the past when palaeo-ENSO reconstructions are most robust. They found that ENSO reconstructions are most reliable from 1580-1700, and from 1825 to present.
A successful workshop on the science of multi-year drought was recently held at Monash University in Melbourne, where 50 experts from Australia, and small number of experts from the UK and the US, met to discuss what we know about the science of these droughts in Australia.
The selected student will simulate past events of rapid climate change with an Earth System Climate Model and compare the simulated changes in biological productivity with existing data from sediment cores.
Past observations suggest future global warming may eventually be twice as warm as projected by climate models under business-as-usual scenarios and sea levels may rise 6m at 2°C.
