Climate science is right – but it isn’t winning. NASA

Is it time to take science out of the climate change debate?

Scientists tell us that the world is warming and greenhouse gas emissions are to blame. Yet climate change framed by scientists, politicians and economists as a straightforward pollution problem will neither…
Antarctica has actually been protected from sea ice melt by the ozone hole. Vassil Tzvetanov

The ozone hole leaves a lasting impression on southern climate

Many people think of sunburn and skin cancer when they hear about the ozone hole. But more ultraviolet (UV) radiation isn’t the only problem. The ozone hole has also led to dramatic changes in Southern…

Your coastal town’s climate score? There’s a website for that

Australia’s coastal towns, many built around fisheries and tourism, are particularly vulnerable to climate change. South east and south west Australia are marine hotspots — they are warming much faster…
Science can’t tell us exactly when the rising oceans will swallow up the Maldives, but it can give us a good idea. Hiroyuki-H

Why climate ‘uncertainty’ is no excuse for doing nothing

Former environment minister Owen Paterson has called for the UK to scrap its climate change targets. In a speech to the Global Warming Policy Foundation, he cited “considerable uncertainty” over the impact…

Plants absorb more CO2 than we thought, but …

Through burning fossil fuels, humans are rapidly driving up levels of carbon dioxide in the atmosphere, which in turn is raising global temperatures. But not all the CO2 released from burning coal, oil…

15 years from now, our impact on regional sea level will be clear

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…

New Zealand is drying out, and here’s why

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…

Human hands are all over Australia’s hottest ever year

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. AAP Image/Delta Harpley

‘Wait and see’ on climate? No, the science is clear: act 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…

How to become a citizen climate sleuth

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…

Appeals to the climate consensus can give the wrong impression

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…

‘Abnormal autumn’ shows the climate system is in a foul mood

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…

IPCC report: adapt to cope with climate change

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…

Explainer: what are ice cores?

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…

Australia’s hottest year was no freak event: humans caused it

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…

Indian Ocean linked to bushfires and drought 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…
