Greenhouse gases and aerosols

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.

Climate modelling increases our understanding of the impacts of climate change including risk of fire, flood and cyclones. But can we rely on climate projections to manage future risk?

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.

Meat consumption has been on the increase with improved standards of living and growing populations around the world. But how do you quantify the environmental cost of feeding the stock feeding that increase?
