Bushfires cloud air pollution problem
Scientists believe more bushfires generated by rising temperatures and lower rainfall will lead to lower air quality over a greater number of days in Australia, particularly in the south-east.
Climate is warming – despite 'ups and downs'
Periodic short-term cooling in global temperatures should not be misinterpreted as signalling an end to global warming, according to an Honorary Research Fellow with CSIRO Marine and Atmospheric Research, Barrie Hunt.
Deep thinking on the world’s oceans
The world's deep ocean researchers – scientists whose field of interest extends into the uncertain world below about 2000 metres – met in Hobart this week to discuss deep ocean changes, their causes and their implications.
Global warming’s influence on El Niño still unknown
The climate of the Pacific region will undergo significant changes as atmospheric temperatures rise but scientists can not yet identify the influence it will have on the El Niño-Southern Oscillation (ENSO) weather phenomenon.
Marine reserves mend food chains, link by link
Conservation managers need to take a long-term view when assessing the value of marine protected areas, according to a paper in today’s Proceedings of the National Academy of Sciences of the United States of America.
More research into rainfall lows to improve predictions
Factors that influence extra-tropical rainfall depressions near Australia’s east coast need to be given more attention in modelling of both seasonal climate variability and long-term climate to improve rainfall predictions.
New coastal research body to turn science into action
An A$11 million collaboration aimed at helping Australia translate science into practical applications for adapting to climate change, population growth and other coastal pressures will be launched today in Perth.
Scientists question fisheries health test
A measure widely advocated as a means of assessing the health of marine ecosystems is an ineffective guide to trends in biodiversity, and more direct monitoring is needed, a new study has found.
Massive Southern Ocean current discovered
A deep ocean current with a volume equivalent to 40 Amazon Rivers has been discovered by Japanese and Australian scientists near the Kerguelen plateau, in the Indian Ocean sector of the Southern Ocean, 4,200 kilometres south-west of Perth.
Southern Ocean winds open window to the deep sea
Australian and US scientists have discovered how changes in winds blowing on the Southern Ocean drive variations in the depth of the surface layer of sea water responsible for regulating exchanges of heat and carbon dioxide between the ocean and the atmosphere.
We will need to adapt to rising sea levels
The authors of a new book have called for the development of more robust international ocean and ice sheet monitoring and modelling programs designed to help community adaptation planning keep pace with the threat of rising sea levels.
A new leaf turns in carbon science
A new insight into global photosynthesis, the chemical process governing how ocean and land plants absorb and release carbon dioxide, has been revealed in research that will assist scientists to more accurately assess future climate change.
Deep-ocean sentinels on northern climate watch
Three deep-ocean moorings have become the foundation for a new drive to measure change in currents linking the Pacific and Indian Oceans through the Indonesia Archipelago – a key factor influencing Australia's climate.
East Coast gliders yield valuable marine life data
The influence ocean eddies have on marine life in the oceans surrounding Australia’s south-east is expected to become clearer after scientists examine data from new deep-diving research ‘gliders’ patrolling the East Australian Current.
Forests absorb one third our fossil fuel emissions
The world’s established forests remove 2.4 billion tonnes of carbon per year from the atmosphere – equivalent to one third of current annual fossil fuel emissions – according to new research published today in the journal Science.
