It looks as though everyone will be happy to sign the next global climate agreement, due in 2015. Why? Because there will be very little in the agreement that will force countries to act on climate change…
Sometimes even the clearest signs of change are ignored.

When President Obama last week tweeted that “97% of scientists agree: climate change is real, man-made, and dangerous” it drew the attention of his 31 million followers to the most recent study pointing…
Warming may be slower than we expected, but it’s still happening.

A new study published today suggests that the short-term warming due to increasing greenhouse gases may be less than previously feared. However, when we look at the bigger picture, we still find that climate…
We aren’t irreversibly committed to a warmer world.

There is a commonly held belief among both scientists and the general public that there is a delay between the CO2 emissions we put into the atmosphere, and the resulting climate change. As a consequence…
Both sides of politics need to take the carbon tax fight to the election.

If climate change features prominently in the federal election campaign, it will almost certainly be driven by the Coalition. Under Tony Abbott, the Coalition has long smelled blood in the water on climate…
Despite a promised repeal of the carbon tax, the Coalition’s Direct Action Plan may miss the opportunity to drive energy innovation.

It looks likely that the next Federal Government will be a Tony Abbott-led Coalition Government. Mr Abbott promises, if elected, to repeal the carbon tax. Labor may block that repeal, but if they do Tony…
Giant creatures such as the marsupial ‘lion’ (Thylacoleo carnifex) didn’t die out from hunting.

Throughout the Ice Age that characterised our planet for much of the last two million years or so mainland Australia, Tasmania and New Guinea formed a single landmass — Sahul. It was a strange and often…
The Mountain Pygmy-possum is clinging to existence in its alpine refuges.

The Mountain Pygmy-possum (Burramys parvus) is one of five living species of pygmy-possum, all of which are classified within a single family. It is the largest of the pygmy-possums, and can be easily…
Yes, some parts of Europe used to be warmer. But the world is warmer overall, and the evidence for it being human-induced is mounting up.

Three new studies were published today, each looking at a different aspect of the human impact on climate, each carrying a sobering message on the consequences of human activities on our environment. The…
The body of people and organisations speaking out against fuel and energy subsidies is growing.

More than half of global greenhouse gas emissions come from burning fossil fuels. Reducing and eventually eliminating fossil fuel use is a critical priority. Most of the world’s remaining fossil fuel reserves…
The Climate Commission is leading the way on climate change communication with its latest report providing scientific context for extreme weather events.
Climate Commission
The Climate Commission’s latest report, released recently, and some of the media that arose from it are excellent examples of science and journalists working together to talk about climate change and extreme…
Every which way but forward. Are biofuels an answer to aviation emissions we can agree on?

Aviation is a growing source of greenhouse gas emissions. In other industries emissions are declining, or at least are better regulated. Airline emissions, however, continue to soar. How viable are laws…
Antarctica’s delicate marine ecosystems are under threat from climate change and ocean acidification.

When it comes to climate change, temperature is only part of the story. Climate gases released by human activity are dissolving into the oceans, and the increased levels of CO₂ are making the waters more…
Blackouts remind us what life was like before cheap, readily available electricity - but it’s time to think about the true price of our power.

No lights, no power, no internet - and no easy solutions. Fumbling around in a middle of a blackout, hoping to find a torch or some spare batteries, I was struck by just how utterly dependent most of us…
Even in Tasmania, it’s been hotter than it should be.

Daylight hours are dwindling and our first month of autumn is ending. But in many places, March felt a lot like summer. Get used to it: looking ahead, all indications are that future summers could be just…
Mass extinctions caused by rapidly escalating levels of CO2 have occurred before.

It’s long been known that massive increases in emission of CO2 from volcanoes, associated with the opening of the Atlantic Ocean in the end-Triassic Period, set off a shift in state of the climate which…
A proportion of investors want to avoid controversial asset classes - but would it pay off?
One quarter of Australians would be willing to switch superannuation funds to avoid investing in coal or coal seam gas, according to a recent survey. Not only does this research raise important questions…
People affected by floods move to higher grounds in Khoski, Sindh province, Pakistan, 17 September 2011.

The northern hemisphere has experienced a spate of extreme weather in recent times. In 2012 there were destructive heat waves in the US and southern Europe, accompanied by floods in China. This followed…
Recent research shows an acidifying ocean is more damaging to coral than we’d hoped.

Ocean acidification - where the ocean becomes less alkaline as it absorbs excess CO2 from the atmosphere - has been described as the evil twin of global warming. Yet, remarkably, it is only over the past…
Heat, floods and fire: it’s not just weather.

The hottest summer on record. The hottest month on record. The hottest day ever recorded for the whole of Australia. Heatwaves, bushfires, record rainfall and floods – extreme events across the land. This…
Another summer, not quite like the other summers.

We all know what to expect from summer in Australia. From December through March it will be hot, there will be storms and floods, and there will be bush fires. It’s been like that for as long as history…
Australia’s latest summer has been significant for weather and for climate.

This summer hasn’t just felt hot. It’s been hot. In fact, the summer of 2012-13 is now the hottest on record. Average temperatures beat the record set in the summer of 1997-98, and daytime maximum temperatures…
