Fewer rain storms across southern Australia

Decreasing autumn and winter rainfall over southern Australia has been attributed to a 50-year decrease in the average intensity of storms in the region – a trend which is forecast to continue for another 50 years.

Redefinition of "seawater" to aid climate research

The science behind understanding the movement of heat through the world’s deep oceans is entering a more exact phase with the adoption of a new thermodynamic definition of what constitutes "seawater".

CO2-chomping microbes battling for ocean iron

Australian, Belgian and New Zealand scientists have expanded our understanding of the way phyoplankton take up scarce iron in the ocean – a process that regulates ocean food chains from the bottom up and helps remove up to 40 per cent of carbon dioxide (CO2) from the atmosphere.

Global CO2 emissions may set a record this year

Global carbon dioxide emissions contributing to atmospheric warming show no sign of abating and may reach record levels in 2010, according to the Global Carbon Project (GCP), supported by CSIRO’s Marine and Atmospheric Research Division.

Ocean salinities show an intensified water cycle

Evidence that the world's water cycle has already intensified is contained in new research to be published in the American Journal of Climate.

Marine scientist wins prestigious Pew Fellowship

One of the world’s most prestigious awards for scientific research into the challenges facing the world’s oceans – a Pew Fellowship in Marine Conservation – has been won by a senior ecosystem modeller with CSIRO’s Wealth from Oceans Flagship, Dr Beth Fulton.

Prince William receives local view of global science

CSIRO today will brief His Royal Highness Prince William of Wales KG on its contribution to international research into climate change, marine biodiversity, and fisheries.

Long-term study to monitor WA’s Burrup rock art

A four-year monitoring project has found no evidence that emissions from industries located on the Burrup Peninsula are damaging the Heritage-listed Burrup rock art.

GREENHOUSE 09: new climate change challenges

Australia’s biennial climate science conference – GREENHOUSE 2009 – opens next week in Perth with a review of the latest Australian and international science contributing towards an understanding of climate change.

Carbon sinks losing the battle with rising emissions

The stabilising influence that land and ocean carbon sinks have on rising carbon emissions is gradually weakening, say scientists attending this week’s international Copenhagen Climate Change Conference.

Algae could fuel cars and jobs

The production of biodiesel from algae could reduce greenhouse gas emissions, help to address future fuel shortages and create jobs in rural Australia.

Aerosols – their part in our rainfall

Aerosols may have a greater impact on patterns of Australian rainfall and future climate change than previously thought, according to leading atmospheric scientist, CSIRO’s Dr Leon Rotstayn.

GREENHOUSE 09: new climate change challenges

New directions in Australian climate research, strategies to adapt to a changing climate and emerging energy options will dominate discussion at Australia’s leading climate change science conference – GREENHOUSE 2009 – in Perth from 23-26 March.

Scientific sub makes deep-sea discoveries

A four-week expedition to explore the deep ocean south-west of Tasmania has revealed new species of animals and more evidence of impacts of increasing carbon dioxide on deep-sea corals.

New ‘seawater’ – the way ahead for ocean science

A proposed new definition of ‘seawater’ is drawing the attention of the world’s oceanographic community in a change that will advance the accuracy of climate science projections.

Air pollution model takes off

Australia’s capabilities in understanding the impact of air pollution have advanced with a new version of software that can predict the direction and concentration of odours and pollutants.

Spring bloom brings ‘jelly balls’ to NSW coast

An unusual abundance of jelly-like creatures has been discovered in waters along the NSW coast from Sydney to Newcastle during a marine survey of the region by a team of scientists from the University of New South Wales (UNSW) and CSIRO.

Global methane levels on the rise again

After eight years of near-zero growth in atmospheric methane concentrations, levels have again started to rise.

CSIRO Melbourne air quality survey volunteer call

Atmospheric scientists at CSIRO are about to undertake an important survey of air quality in private homes – but they need community assistance.

Emissions rising faster this decade than last

The latest figures on the global carbon budget to be released in Washington and Paris today indicate a four-fold increase in growth rate of human-generated carbon dioxide emissions since 2000.

Over 100 new sharks and rays classified

Australian scientists have completed an ambitious 18-month project to name and describe more than 100 new species of sharks and rays.

Permafrost carbon content double the old estimates

New research indicates that the amount of frozen organic carbon locked away in the world’s permafrost regions – a major potential source of atmospheric carbon dioxide (CO2) and methane (CH4) – is double what has been previously estimated.

Australia’s ocean research ship open to Sydneysiders

The Marine National Facility’s Research Vessel, Southern Surveyor, will be open to the public for guided tours at the Australian National Maritime Museum, Darling Harbour, Sydney, from 2-20 September.

Workshop: aerosols’ impact on Australia’s climate?

The impact that human-generated and natural atmospheric particles (aerosols) could be having on Australia’s climate will be discussed next week in Canberra at a workshop involving some of the world’s leading experts in the area.
