As the world warms, Antarctica's melting ice will likely reach the point of no return.
Ice cores tell us vital information about how the world's climate has changed - and how it will change in the future.
Use of methamphetamines has increased significantly in young people already at risk of other drug and alcohol related dependence and harm.
With use of drugs such as ice on the rise, drug consumption rooms are now being set up in Europe to provide supervised inhalation.
To tackle the ice problem, the government must learn from experience and avoid adopting a blinkered law enforcement approach.
The ice taskforce's report sends a clear message about the importance of focusing on drug use as a health issue. This signals an important shift in thinking.

Are addicts sick and helpless victims with little control over their own behaviour, or brazen criminals who deserve to be punished accordingly?
There is no evidence to suggest mandatory treatment outside of the criminal justice system would work. Instead, we need to increase funding for treatment programs, including early intervention.
To create accurate models that predict how ice sheets and oceans will react to changing climate, modelers need precise current data. One researcher heads to the ends of the earth to collect just that.
Today's organised crime occurs through loose and undefined networks made up of criminal entrepreneurs and freelancers with little concern for group branding or loyalty.
Much media attention is being given to the rising toll of methamphetamine-related harm in Australia, fuelled by the increased availability and use of high purity crystalline meth.
