Marine cloud brightening: it’s a concept that has been floated in climate engineering discussions for some time. But what are the moral implications of this geoengineering technology, and how likely is…
The Great Barrier Reef has lost half its coral cover in the last 27 years, and it could halve again by 2022 say researchers from the Australian Institute of Marine Science. A study published today in the…
Climate change has been significantly absent from the US presidential election campaign. President Obama, who made climate change a key plank of his 2008 campaign, has not been anywhere near as vocal in…
We have unwittingly hardwired a bushfire ignition source throughout our flammable landscapes – powerlines. Powerlines can fail under any conditions but the risk increases on days of high bushfire risk…
Around the clock solar power could be a reality for Australians in the foreseeable future, but experts say a hostile state government stands in the way of Queensland becoming the solar power leader suggested…
Climate change will lead to significant human displacement. The Intergovernmental Panel on Climate Change (IPCC) and other groups warn that the effects – including rising sea levels, heavier floods, more…
The linear nature of global warming trends projected by the IPCC since 1990 and as late as 2007 (see Figure 1) has given the public and policy makers an impression there is plenty of time for economies…
A combination of 33-year satellite records, measurements made over the past century, and long-term proxy analysis suggests Arctic sea ice may be at its lowest level for more than 1,000 years. According…
Within decades, environments across Australia will be substantially different from those that currently exist. CSIRO research released today suggests that, by 2030, climate change stress on our natural…
One of the ambitions of the United Nations Framework Convention on Climate Change (UNFCCC) is galvanising the international community to avoid dangerous interference with Earth’s climate. To do this, it…
SAVING THE OZONE: Part five in our series exploring the Montreal Protocol on Substances that Deplete the Ozone Layer – dubbed “the world’s most successful environmental agreement” – explores the parallels…
The 2012 northern hemisphere summer, like its two predecessors, has seen a wide range of climate extremes, many involving heat. In most recent summers there has been at least one part of the world with…
The chances of being roared at by a jaguar in a Mexican cloud forest are already low, but that is precisely what happened to me during a recent fieldwork expedition. I was very lucky to see a jaguar close…
I have a challenge for the next time you’re at work. Take a look around at your colleagues. Now look at yourself. What are you wearing? It’s still winter (just), so if you’re in the southern states you…
