Gathering data at the calving front of the Ilulissat Glacier, Greenland.
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.
Are authorities too focused on the usual suspects and missing the new and emerging markets in organised crime?
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.
Forms of methamphetamines that can be smoked or injected have greater risks.
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.
Could random testing put a dent in the drug market?

It is unlikely that drug testing in workplaces and at nightclubs will have any discernible impact of rates of use.
Prime Minister Tony Abbott is dealing with a very different COAG to the last one he chaired.
Bitter battles about money hang heavily over the Council of Australian Governments meeting, though Tony Abbott wants it to concentrate on the less divisive topics.
Only a small proportion of Australians who use methamphetamines fall into a category of dependent users.
There is no doubt methamphetamine can cause harm. But when politicians hijack drug issues and overplay them for political purposes, that too can cause harm.
The number of people who use methamphetamine has not changed in at least the last ten years.
Prime Minister Tony Abbott today launched a taskforce to tackle the growing problem of ice. But while Australia certainly has a problem with ice, it's hardly an epidemic.
Methylamphetamine, in particular crystal meth or ‘ice’, has been the subject of much scrutiny in Australia in recent times.
How does the ACC report help inform the debate around methylamphetamine, and what practical lessons can Australian society and law enforcement draw from it?
We can’t figure it out.
For several years now climatologists have puzzled over an apparent conundrum: why is Antarctic sea ice continuing to expand, albeit at the relatively slow rate of about one to two percent per decade, while…
Rates of ice use remain stable.
Looking at recent news headlines, you’d be forgiven for thinking Australia was being overrun with methamphetamine, with reports of skyrocketing use. The focus is largely on crystal meth, also known as…
The market for the drug is controlled by criminals recruiting dependent users to act as their agents, who recruit yet more users to keep feeding their addiction.
Recent news of former NSW premier’s daughter Harriet Wran being charged with murder is another illustration of Australia’s growing problem with the drug ice. Wran, who is said to have been battling an…
After long periods of regular use, changes to the dopamine system can mean users appear flat and unmotivated.
If you’ve listened to the news lately, you might think that Australia is overrun with uncontrollably violent people on crystal methamphetamine. This may be true of those in crisis, but the bigger picture…
We need to know more about how ice sheets interact with the warming oceans and warming atmosphere.
Satellite and in situ observations show sea level is continuing to rise. In the last Intergovernmental Panel on Climate Change report, earth system model projections indicated global sea-level rise by…
Melting Arctic Sea ice should be the warning we need about expanding coal exports.
Despite peak global temperatures in 2005 and 2010 (unprecedented in the instrumental record), a recent sharp plunge in volume of the Arctic Sea ice and a spate of extreme weather events, coal mining, coal…
New research from Purdue and Yale Universities suggests that a drop in carbon dioxide was a driving force in the formation…
Around 50% of Canada’s ice shelf has disappeared in the last six years, researchers say.

Half of Canada’s ancient ice shelves have disappeared in the last six years, researchers have said, with new data showing…
Arctic sea ice coverage is at its lowest since observations began in 1972. Ice coverage in the Arctic has declined by 11…
New research indicates that although Arctic sea ice will melt away as the climate continues to warm, it may temporarily stabilise…
For the first time scientists have observed the power of a tsunami to break off large icebergs in Antarctica. The tsunami…
Abuse of methamphetamines like ice are at increased risk of developing Parkinson’s disease, a study has found.
People hospitalised for abuse of methamphetamines like crystal meth or ice have a 76% higher risk of developing Parkinson’s…
