Greenhouse gases and aerosols

The recent, rapid rise in levels of methane in our atmosphere is causing concern among scientists. So why is it happening?

CSIRO scientists have developed a new way to account for ozone in computer simulations of the climate. This latest modelling shows that the oceans take much less ozone out of the atmosphere than previously thought. This has implications not only for our understanding of future global warming, but also on human health, plant productivity and the economy.

For several years, emissions of CFCs have been rising, in apparent defiance of a global ban in place since 2010. A new global detective effort has traced the source to two eastern Chinese provinces.

ACCURATE, reliable and comprehensive information about what is happening in our atmosphere is a critical piece of the puzzle if we are to mitigate and adapt to our changing climate.

To mitigate climate change we might have to re-examine the rules which define carbon credit-worthy sequestration actions – that might include renting, rather than buying.

Accounting for emissions savings in producing biofuels compared to fossil fuels is about to get harder. Australia's got an interest in proving the worth of canola.

Contrary to popular belief, the ozone hole does not reach Australia. But its effects are felt the world over. CSIRO scientists are creating a climate-chemistry model that will lead global science on the ozone hole recovery.

Understanding potential greenhouse gas impacts of the coal seam gas industry can help inform future decisions, including better understanding of methane.

Before the RV Investigator came along, the atmosphere of the Southern Ocean had been measured only a handful of times. With regular monitoring, this pristine and critical environment may now reveal the real role of atmospheric aerosols in global warming.
