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.

Breathe easy – no 'nasty surprises' in air study

A CSIRO study of the quality of air inside the typical Australian home has not revealed any nasty surprises.

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.

Going high-tech to probe deeper into oceans

Australian scientists are preparing to use the data from a new $22m array of high-tech equipment to help them probe deeper into the nation’s surrounding oceans.

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.

Nationwide sea-floor ecology study starts off WA

The first stage of a long-term observation study of the ecology of Australia’s sea-floor was recently launched off Western Australia’s Rottnest Island.

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.

Climate now: New state of the Climate Snapshot

More extremely hot days, fewer cold ones wetter in the north and drier in the south: this is not a forecast for Australia’s climate but a snapshot of our climate now.

Tasmanian scientists expand their view of the ocean

Tasmanian scientists will soon have unprecedented access to data from high-tech equipment for monitoring coastal and ocean ecosystems.

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.

Animal trackers make tracks for Hobart

King penguins in the Indian Ocean ride ocean currents to eddies rich with fish before making a bee-line back to their chicks.

Auditing the Earths sea-level and energy budgets

An international research team has balanced the sea-level rise budget by showing that the total amount of contributions to sea level rise explains the measured rise over recent decades.

When times are tight, focus on adaptation

Biologists have been advised not to over-commit time and effort establishing broader climate change links to local ecological impacts.

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.

Emission sources identified in Huon Study

Emissions from domestic wood-fired heaters in southern Tasmania's Huon Valley dwarf emissions from forest regeneration burns, according to a new CSIRO study.

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.

Future fire – still a wide open climate question

How the frequency and intensity of wildfires and intentional biomass burning will change in a future climate requires closer scientific attention, according to CSIRO’s Dr Melita Keywood.
