Good climate models can predict and help us respond to weather events.
Climate and weather models have come far in recent decades, and Australia has one of the best.
Is it getting hotter, Nigel?
Backtracking on climate policy would make achievement of a global climate agreement much more difficult, with disastrous results.
You can’t hide from global warming, Mr Wabbit.
Rabbits and hares will flee towards the poles as global warming changes the places they once called home.
Right to roam?
Ambitious climate targets, but nature policies leave a lot to be desired.
Welcome to your summer holidays, 750m years ago.
More evidence that planet Earth has gone through various frozen phases.
Can Pope Francis spread the idea that protecting nature a moral issue?
The upcoming encyclical from Pope Francis can transform the climate change culture wars in America.
Climate change is affecting gender ratios in fish, and could hamper their ability to return to a 50:50 balance.
Warmer temperatures can throw off the gender balance in some species. But some fish can adjust their offspring's gender to compensate, but only if temperatures don't rise too high.
Climate models show Sydney could get drier or wetter. Which scenario do we choose when making decisions?
Depending on what model you use, climate change could make Sydney a little bit warmer, much hotter, wetter, or drier. Which one should we use? When it comes to planning for climate change, it's important to look at all the possible futures.
Under a high emissions scenario, Melbourne’s climate could end up more like Dubbo’s in New South Wales.

Melbourne to Adelaide, Sydney to Brisbane: climate change could move the climate of Australia's towns and cities, as revealed by a new website.
The US proposes to meet its climate targets through regulation, including reducing carbon emissions from coal power plants by a third below 2005 levels.
The United States' post-2020 climate target raises many questions for this year's global climate talks, and puts pressure on Australia to raise the stakes.
The US has formally submitted its post-2020 climate target to the UN.

The US has made its formal submission of climate targets beyond 2020. But Australia continues to twiddle its thumbs.
BP’s energy outlook would make it difficult to keep warming below 2C.
BP's Energy Outlook report forecast an increase in fossil fuel use by a third. That would make it difficult to keep warming below 2C.
In the Anthropocene, human-driven forces are shaping the planet in ways that may risk the collapse of human civilisation.
The Anthropocene, as an epoch of human-driven planetary change, poses huge environmental and political problems. But it could also force us to develop proper ecological and democratic accountability.
Observations from space have shown the world overall is getting greener despite deforestation and drought.
A new investigation of satellite records reveals that the Earth is getting greener, despite ongoing deforestation in Indonesia and South America.
Antarctica’s Brunt Ice Shelf photographed in October 2011 from NASA’s DC-8 research aircraft during an Operation IceBridge flight.
Researchers find that ice around Antarctica shrank quickly last decade, raising concerns over this buttress against melting land-based ice and future sea-level rise.
Clumps of thunderstorms are driving increases in rain over tropical oceans.

For a long time climate models have forecast increasing rainfall in tropics. Now we know part of the reason: clumpy thunderstorms.
An iconic photo - Earthrise taken by Apollo 8 astronauts in 1968 - reflects how humans must now think of managing the Earth as a whole system.
Rather than impose regulations to limit carbon emissions, policies should focus on innovation and systems change through social sciences.
Tracking the world’s efforts to reduce greenhouse gases.
In the lead up to climate meetings in Paris at the end of the year, countries will release draft targets - the framework of a possible global climate deal. Follow our interactive map as we track these targets.
It’s hard to know for sure what role climate change played in the intensity of Cyclone Pam.

A causal relationship between cyclone behaviour and anthropogenic global warming is a very real possibility. But most climate scientists hesitate to attribute any single event to global warming.
Australian has moved swiftly to fly relief aid and personnel to Vanuatu but has been less responsive to Pacific Islanders' pleas to act on climate change.
While Australia’s leaders express concern for the people of Vanuatu, the welfare of poor states is a commitment from which Australia is walking away.
