    Australia's leading science body has reissued its climate change booklet in a bid to improve public understanding of the contentious subject.
    The Australian Academy of Science was prompted to update the information based on new research and public questions since its original release in 2010.

    • For Australia, a warmer future will likely mean that extreme precipitation is more intense and more frequent, interspersed with longer dry spells
    • By the end of the century, a high temperature event that would now occur only once in every 20 years would be occurring annually or once every two years on our current emissions trajectory, the academy says
    • average surface warming had slowed since 2001 despite rising carbon emissions but said decadal variability in how oceans and the atmosphere exchange heat meant extra warmth had been absorbed by the seas. Other changes such as the increasing incidence of heat extremes, shrinking Arctic sea ice – its thickness dropping 30 per cent in 30 years – and rising sea levels had all continued unabated.
    • global carbon dioxide emissions rose at an average annual rate of 3.2 per cent between 2000 and 2012, at the top end of previous projections. These emissions, though, will have to start falling at a pace between 5.5 and 8 per cent for the planet to have a 50-50 chance of keeping temperature increases to within 2 degrees of pre-industrial levels.
