The Climate Commission is leading the way on climate change communication with its latest report providing scientific context for extreme weather events. Climate Commission

And now to the weather: climate science on the front foot

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…

Europe’s rollercoaster carbon prices set to hit Australia

Australia’s key strategy to tackle climate change is looking shaky, after another price drop on the world’s biggest carbon market raised fresh doubts about the future of emissions trading schemes. In Europe…
Every which way but forward. Are biofuels an answer to aviation emissions we can agree on? pearsongraphics/Flickr

Not even Nobel prize winners can fix aviation emissions

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…
Air pollution has been found to have affected coral growth in the Caribbean over many decades. Lester Kwiatkowski, University of Exeter

Air pollution casts a cloud over coral reef growth

Tiny particles of air pollution can stunt the growth of coral reefs, according to a [new study in Nature Geoscience](http://dx.doi.org/10.1038/ngeo1780](http://dx.doi.org/10.1038/ngeo1780). Using coral…

Warning bells: what Antarctica can teach us about 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. Candle in the dark image from www.shutterstock.com/Ronen

Save now, pay later: the hidden costs of lower electricity bills

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…

Another link between CO2 and mass extinctions of species

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?

Can super investors really bank on ethical investment?

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…

Warmer climate boosts northern crops but the bad soon outweighs the good

Climate change is creating warmer growing conditions in parts of the Earth’s northern regions, a new study has found, but experts warn that drought and heat wil soon cancel out the agricultural benefits…

Current temperatures hotter than history

Today’s temperatures are nearly unprecedented in the past 11 000 years, a new study from Oregon State University has found…

Weather extremes: atmospheric waves and climate change

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. Community Eye Health

Jumps in ocean acidity put coral in more peril

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…

Angry summer shaped by a shifting climate

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…
