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…
New Jersey was hit hard by the storm surge.

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…
Recent extreme weather doesn’t tell us how the future will be.

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…
Sea levels are rising globally at record-breaking rates and Antarctica is playing an increasing role.
Matt King
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…
In some parts of Queensland, half the plant species may be displaced.
Laura Thorn
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…
Methane locked under the Arctic ice could take climate change to a whole new level.
Antonio Delgado Huertas
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…
Children suffer around 90% of the disease burden from climate change.

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…
Brightening and increasing a cloud’s longevity would help reduce the effects of global warming.

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…
Mitt Romney and the Republicans are openly sceptical of climate change.

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…
The role of powerlines in bushfires is raising some pressing issues of climate change adaptation.
Paul Hocksenar
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…
Humans as well as animals are affected by climate change. A treaty could keep them safe and reduce forced migration.
AAP
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 climate system is highly sensitive to radiative forcing, so it’s no wonder we’re seeing more extreme weather events. Isn’t it time to take notice?
AAP
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…
Will we ultimately see 2012 as triumphant, or as just one step in an emerging global tragedy?
Jenny Varley
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…
We don’t know what the Australian landscape will look like in 50 years, but we know it will change.
Tezza #
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…
We thought we’d set a safe limit on climate change - 450ppm CO2 - but it may be too high for most of the world’s reefs.
Paul Toogood
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…
Is there a relationship between the ozone hole over Antarctica and the global climate?

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…
Over summer, the US has been dry and hot. It’s not alone.
EPA/Larry W Smith
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…
Bumping into a jaguar in Mexico’s cloud forest could soon be a thing of the past.

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…
Office temperature regulations are bad for comfort and the environment.
Kim n Cris Knight
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…
US development of wind energy is lowering emissions without reducing economic growth.
Sam Beebe
Ninety countries representing 90% of the global economy are committed to reducing their greenhouse emissions and are taking action to do so. This is one of the take-home messages from the Climate Commission’s…
Could listening be the way forward for scientists and science?

Want to help fix the science/ society divide? We’re making a documentary looking at how we might do this, and we’re looking for your help. Why? Well … You don’t need to be a rocket sociologist to know…
The news treats nature as a backdrop to the dramas and delights of human life. In the 21st century, our dramas are driving nature’s destruction, and that destruction threatens an end to our delights. But…
Little penguins are among a number of species that are threatened by climate change.

Fish are on the move in Australia’s waters. In southern Australia, scientists, commercial and recreational fishers, divers and beach-goers are reporting the presence of new species. The movement of species…
Coral species Acropora monticulosa is becoming more abundant at the Solitary Islands in northern NSW.
The east coast of Australia is a global hotspot for the effects of climate change, especially in the marine realm, where average water temperatures have increased by almost half a degree over the last…
Many Australians think they have experienced events associated with climate change.

Where one stands on “climate change” has been such a vexed and often confusing issue, at dinner parties, over coffee, with the taxi driver, and in terms of media reporting of where the Australian public…
