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.

CLEX researchers and colleagues discovered which species are most important in transferring climate change impacts through the ecosystem using a model that simulated the southeast Australian ecosystem through to 2050.

A new framework for cyclone jet interaction improve our understanding of how the turbulent atmosphere is organised in coherent motions via the jet stream

This work examines how climate projections are affected by using different subsets of available climate models. The researchers find several variables need to be optimised independently to get the best results.

An improved Tropical Pacific Observing System that is responsive to user needs will provide for better understanding and prediction of the climate system, which will reduce climate uncertainty for society.

We can expect more occurrences of extreme weather associated with eastern Pacific El Niño events (the strongest and most destructive of the two types of El Niño events), which will have pronounced implications for the twenty-first century climate, extreme weather and ecosystems.

CLEX researchers propose that 21% of the heat carried across the Subantarctic Front south of Tasmania is achieved by long-lived, cold-core eddies entering the Subantarctic Zone.

The ocean plays a critical role in the climate system by transferring heat from the tropics toward the poles, helping to regulate regional climates. How this heat transport may change in the future remains a first order question in climate science.

Antarctic sea ice extent underwent a rapid decline in the spring of 2016 and is still well below average now. CLEX researchers have tied the decline to natural variability of both the atmosphere and ocean in two articles published in Nature Communications this month.

In 2016, Centre of Excellence for Climate Extremes researchers and colleagues measured Southern Ocean INPs for the first time in over four decades. The numbers of these particles were extremely low compared to other oceans and 100 times lower than the previous Southern Ocean measurement program conducted in the 1970s.

Deep ocean reefs are likely to transform with global warming bringing together species from temperate and tropical waters that may have never coexisted before, according to new research published in Nature Climate Change.
