In his acceptance speech of November 6, Barack Obama at long last reaffirmed the need to address global warming. But unfortunately he also reaffirmed the spurious goal of US oil independence, which can…
Global drought has not increased significantly over the past 60 years, a report in Nature has found. Previous assessments of global drought have relied on the Palmer Drought Severity Index, which only…
What is the oldest debate in Australian science? Probably, the argument over what caused extinction of our Pleistocene megafauna – the diprotodons, giant kangaroos, marsupial tapirs, über-echidnas and…
Market-distorting fossil fuel subsidies rose 30% from 2010 to 2011, stymying efforts to boost the renewables sector and reduce greenhouse emissions worldwide, a new global report has found. The 2012 World…
The Minister for Climate Change and Energy Efficiency, Greg Combet, announced on Friday that Australia is “ready” to join a second commitment period of the Kyoto Protocol to the United Nations Framework…
Ancient Central American rainfall records suggest climate change was linked to the rise and fall of the Maya civilisation between AD 300 and 1000, a new study has found. Giant stone structures throughout…
Why get worked up about our climate responsibilities when Australia’s contribution to global emissions – around 1.5% of the total - is small? Here is the usual reply. Australia’s domestic greenhouse gas…
As Australia gears up for another risky bushfire season this summer, some of its most iconic and valuable forests are at risk. Giant eucalpytus trees rely on fire to regenerate, but an increase in major…
I am writing with Hurricane Sandy having brought devastation to New York and the East coast of the United States. Much has been written on the politics of climate change. But until a few days ago, a severe…
As I write this, the worst coastal flooding effects from Hurricane Sandy’s attack on the densely populated regions of the US northeast are almost over. Even so, the effects have been significant: record…
Are we now experiencing the “new normal” climate? Let’s look at the recent evidence: A storm of historic proportions is moving up the east coast as a Nor’easter without precedent, since no such storm has…
A small slice of Antarctica turns up along your coastline each year. We’re all glad it’s just a small slice, given Antarctica could deliver a total sea-level rise of 59 metres. That’s not going to happen…
Climate change will place increasing pressure on Australia’s natural environments in the future. Queensland is no exception. CSIRO and the Queensland Government recently conducted an in-depth review and…
The risk with climate change is not with the direct effect of humans on the greenhouse capacity of Earth’s atmosphere. The major risk is that the relatively modest human perturbation will unleash much…
Climate change has been widely recognised by leading public health organisations and prestigious peer reviewed journals as the the biggest global health threat of the 21st century. A recently released…
