Greenhouse gases and aerosols
Should I eat more or less dairy if I want a low emission diet?
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.
Climate mitigation: Science-backed solutions to reduce emissions
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?
Capturing fugitive methane emissions
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 intel for the future
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?
Ozone uptake in oceans much lower than previously thought
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.
Eastern China pinpointed as source of rogue ozone-depleting emissions
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.
Watching the world’s atmosphere
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.
Why renting, rather than buying, carbon might help mitigate climate change
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.
How do you measure the environmental footprint of grazing cattle?
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?
