The Indian Ocean Dipole may be El Nino's less famous cousin, but that hasn't stopped it having a profound effect on Australia's weather since it flipped into a "strong negative phase" two months ago.
When temperatures dipped between 1500 and 1750, the world's landscapes responded by storing more carbon. Now, with temperatures climbing, it's possible they will do the opposite and release even more.
South Australia's electricity price spikes during this month's calm weather have been blamed on its reliance on wind turbines. But a bigger problem is the rising price of gas-fired power.
A new UN report puts Australia in 20th place in the global effort to secure health, security and environmental sustainability across the world. Scandinavian nations lead the way, while Africa trails.
Not all of the world's coral reefs are in dire straits. Reef fisheries tend to do better in areas with strong ownership rights, and where people are closely involved in managing their local reefs.
The world's use of finite resources continues to rise as global development continues. Can we help poorer nations raise their standard of living without exhausting all of our raw materials?
There's a wider trend towards linking the energy and climate portfolios, and not before time – the race is on towards a low-carbon economy, and joined-up policy gets faster results.
For birds migrating to the top of the world, the warming climate could severely contract the available space they have to breed.
Will merging the environment and energy portfolios result in joined-up thinking, or one set of ideas steamrollering the other?
It's not just about finding money for things like solar panels – poorer households can also find it harder to gain access to reliable information about the green energy options they do have.

Nauruans used to be some of the richest people in the world, before their mining industry imploded. Now, as the island aims to develop sustainably, there are signs of the green shoots of recovery.

Malcolm Turnbull returns to the helm with a wafer-thin majority and a significant element in his government who still oppose climate action - can he defy the odds and serve up some credible policy?
Polar ice isn't all the same - it can be divided roughly into "land ice" and "sea ice". What matters most for sea levels is how much ice slides off the land and melts in the sea.
New South Wales' ban on greyhound racing is a response to the high rate of animal deaths in the industry. But what about other states, and other animal industries, where the problem is prevalent too?
As Australia joins a New York summit to discuss the UN Sustainable Development Goals, it still faces questions over whether it is meeting water standards at home.
Australasia's warming in recent decades is unprecedented in the past millennium. But a mistake in the paper reporting this finding took four years to fix, and was viciously attacked by bloggers.
The huge numbers of unwanted dogs killed by the greyhound racing industry has led the New South Wales government to outlaw the sport.
A 10-week surge in ocean temperatures off the Western Australian coast has killed off large patches of kelp forest, the "biological engine" of Australia's southern reefs.
Australia and China both have a keen interest in the frozen continent. And while they don't agree on everything, there is great scope for scientific collaboration.
It's one of the remotest places on Earth and yet is still claimed by six nations – including Australia.
