Think politics is frustrating? Welcome to climate negotiations

The latest climate negotiations in Bonn have been stalled for two full weeks and climate multilateralism is in crisis mode leading up to the next major gathering in 2015. So, what is the problem? There…
The IEA thinks we can get a lot more mitigation mileage out of energy efficient vehicles. Shell Eco-marathon

International Energy Agency report hopeful, but is it unrealistic?

The International Energy Agency’s (IEA) latest report repeats the message we’ve heard from many sources - we’re heading for a temperature rise of much more than 2°C. But given its international reach and…
We need to models to understand complex systems: intuition won’t get us there. Kevin H./Flickr

Common sense won’t help you understand climate

Most of us understand the world by using common sense and intuition. To a large extent, this means assuming that most things behave in a roughly linear way: small changes in inputs lead to small changes…
A recent report says CFCs, not carbon dioxide, are the culprit in climate change. weegeeboard/Flickr

Are CFCs responsible for global warming?

On Monday, a report appeared in the Australian claiming a link between chlorofluorocarbons (CFC) in the atmosphere and global warming. The report claimed “banned aerosols” and not carbon dioxide were “responsible…
McKibben has calculated that the world can emit 565 more gigatons of carbon dioxide and stay below 2°C of warming — anything more than that risks catastrophe for life on earth, he says. http://maths.350.org/

Q+A: Bill McKibben crunches Australia’s climate numbers

US environmentalist and scholar, Bill McKibben, has crunched the numbers: we can emit 565 more gigatons of carbon dioxide worldwide if we want to stay below 2°C of warming, he says. However, the world…
Your MP may accept climate change is a problem, but is he or she doing enough to fix it? AAP Image/Alan Porritt

Your MP won’t act on climate change? Ask the tough questions

Politicians are in the unique position of being able to enact climate policies that can prevent or minimise great harm to millions, if not billions, of people. They have an ethical responsibility to understand…
Rising temperatures may have drastic impacts on the world’s wine regions but Tasmania is using climate variability as a driver for innovation. Flickr/santheo

Australia’s farming future: Tasmania

Wine grapes are a sensitive bunch. As Australia’s climate changes, the future of Australia’s viticulture will depend on the adaptability of its wine-growers. Tasmania produces wine with unique, cool-climate…
Climate change is just another variable for Queensland farmers. Lock the Gate Alliance

Australia’s farming future: Queensland

Queensland farmers are used to dealing with variable seasons, but the long-term shifts of climate change are expected to create new challenges. Queensland farmers already do a good job of managing a variable…

Australia’s farming future: Western Australia

Climate change, and its associated variability, is posing a challenge for farm businesses in Western Australia. The grainbelt has experienced a 20% decline in rainfall over the last several decades, more…

Global warming range narrowed

Research from the University of Melbourne and Victoria University has generated more reliable global warming estimates at…

Another budget in massive deficit

Now that the federal budget is out of the way, it’s time to look at another budget soon to be massively in deficit – Australia’s greenhouse emissions budget. Last week, atmospheric concentrations of carbon…
We’ll never know how much the globe will warm, but we have a pretty good idea: what are we waiting for? Luis Ramirez

Uncertainty no excuse for procrastinating on climate change

Today we released research which reduces the range of uncertainty in future global warming. It does not alter the fact we will never be certain about how, exactly, the climate will change. We always have…
Cut from the sea bed this 20m long core contains 100,000 years of climate history. Ian Hall

Humans have a long history of coming together to solve a climate crisis

Responding to a crisis often brings out the best in people. Certainly it has in the past, when sudden changes in climate during the Middle Stone Age sparked off surges of cultural evolution and innovation…

Mapping methane across America

Researchers in the US have done the first ever whole-country study of methane emissions. In some cases they found higher…
You can blink, you won’t miss it. Climate change is here for good. rudecactus

Global warming is here to stay, whichever way you look at it

Has global warming stalled? This question is increasingly being asked because the local weather seems cool and wet, or because the global mean temperature is not increasing at its earlier rate or the long-term…
