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 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.

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.

The devastation to Vanuatu left in the wake of Cyclone Pam shows small islands in the Pacific need a climate insurance scheme, similar to what has been achieved in the Caribbean.
The sea level has gone up about half of a foot since the 1960s on the southern Florida coast, making floods after storms more frequent.

Florida’s coastal populations and its economy face serious threats from rising sea levels caused by global climate change. The state’s response could set an example for other nations around the world.
