Greenhouse gases and aerosols

A recent CSIRO report commissioned by the Climate Change Authority has provided a comprehensive assessment of Australia’s carbon sequestration potential.

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

Australian adults are not eating enough dairy. Some are concerned dairy products have high greenhouse gas emissions. New research shows healthier diets with lower GHG emissions can include dairy.

Science tells us that anthropogenic climate change is in effect. In order to limit the changes to our environments, economies and lifestyles, we must reduce greenhouse gas emissions from a number of sources. This is a huge task, so where should we concentrate efforts and what tools are at our disposal?

Three technologies that mitigate methane emissions, either by destroying the gas or capturing it, are gaining the attention of miners seeking to reduce their emissions.

Australia’s fire season isn’t over yet, but a significant flux of greenhouse gases have already been released into the atmosphere. Our scientists have been exploring their impact.

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.
