Human activity is driving sea levels higher. Australia’s seas are likely to rise by around 70 centimetres by 2100 if nothing is done to combat climate change. But 2100 can seem a long way off. At the moment…

Over 2012 and 2013, parts of New Zealand experienced their worst drought in nearly 70 years. Drought is the costliest climate extreme in New Zealand; the 2012-2013 event depressed the country’s GDP by…
New research shows 2013 would not have been as hot without human-caused climate change.

2013 was Australia’s hottest year on record, but how much of that was due to human-caused climate change? Today scientists publish five research papers that reveal the extent of human influence on Australia’s…
It’s not just protesters: even climate models suggest it’s more sensible to act on climate change now.

When should we act to reduce our greenhouse gas emissions and tackle climate change: now, or later when we know more? One person who thinks we should wait is New York University theoretical physicist…

Antarctic winter sea ice has once again broken the record for maximum extent. On September 12, the coverage measured 19.619 million square kilometres, the highest since satellite records began. The ice…
Temperature data is freely available online - why not investigate.

There has been much media commentary recently about the Bureau of Meteorology’s efforts to use historical weather records to gauge how Australia’s climate is changing. Climate scientists have rejected…
When it comes to arguing about climate science, it would be better to play the science, not the scientists.

You might have heard that 97% of climate scientists agree the world is warming and people are the cause. This level of agreement, known as “consensus”, is often put forward in the climate debate in support…
This isn’t summer: Sydney broke the previous autumn warmth record by 10 days.

The climate system is in a foul mood. From “angry summer” to “abnormal autumn” – we’re running out of words to describe the relentless extreme weather that Australia is experiencing as global temperatures…
Flooding as a result of wetter winters is set to continue.

Climate change is a serious threat to human safety and security according to the latest report from the UN’s International Panel on Climate Change. But also coming through loud and clear is that adaptation…
Ice core samples storing mysteries from bygone eras.

Ice cores are cylinders of ice drilled from glaciers and ice sheets. When snow falls it takes with it a record of many aspects of the atmosphere. As long as no melting takes place, this information is…
The “pause” in global warming since 2001 can be explained by the discovery of unusually strong winds in the Pacific, climatologists have found. Global surface air temperatures have more or less flatlined…
Australia saw extreme heat and bushfires in 2013.

The Bureau of Meteorology has confirmed that 2013 was the hottest year in Australia since records began in 1910. Unusual heat was a persistent feature throughout the year. For the continent as a whole…
Cooling oceans off the coast of Indonesia can create bushfire weather in Australia.

In a study released today in Nature Geoscience, we show that extreme weather events in Australia such as drought and bushfire are linked to temperature changes in the Indian Ocean. Much like El Niño in…
Research is hard, but it’s worth doing properly.
