It's long been known that our diet choices help determine our carbon footprint. But do you know which of your favourite foods are the most water-hungry?
A punter photographs a spread of v2food, which is working to provide a wholly Australian plant-based alternative to meat.
Australian supermarkets and fast food chains will soon be stocking a homegrown meat alternative that tastes and feels like meat and even sizzles on the barbecue.

The IPCC report says extreme sea level events that used to hit once a century will occur once a year in many places by 2050. This situation is inevitable, even if emissions are dramatically curbed.

Very rarely, depending on where you are in the world, your compass can actually point to true north.
Recently, magnetic compasses at Greenwich pointed directly at true north for the first time in 360 years. This is currently happening in Western Australia too. But what does it mean?

Growth in demand for healthy and sustainable products could make Australia's food and agribusiness sector more valuable than mining.
Waves in Australia’s southern coasts are likely to get bigger and faster under a warming climate.

A warming climate will affect the way waves hit over 50% of the world's coastlines, increasing erosion and the risk of flooding.
Are veggie burgers the way of the future?
We don't know enough about the carbon footprint of vegan foods, and that needs to change.
Bleached staghorn coral on the Great Barrier Reef. Many species are dependent on corals for food and shelter.
Corals, mangroves and seagrass habitats have been affected by extreme weather events, and some may never recover.
US astronaut Neil Armstrong on the Moon during the Apollo 11 mission.
When Neil Armstrong stepped on to the Moon 50 years ago this month, Australians saw the images first. Australia even defied bad weather to bring the historic images to the world.

For the first time scientists have located the home galaxy of a one-off fast radio burst. Here's how they did it – and what they learned about the galaxy.
Tourists are experiencing ‘Reef grief’.
Severe coral bleaching may have been the crucial factor in bringing home the reality of climate change for many people.
Most new houses being built in Australia do no better than comply with the minimum energy performance required by regulations.
Australia requires a minimum six-star energy rating for new housing. New homes average just 6.2 stars, so builders are doing the bare minimum to comply, even as the costs of this approach are rising.
Australia’s future prosperity will require bold action on a number of fronts and a deliberate commitment to careful and considered long-term thinking.

If the right changes are made today, Australia’s living standards could be up to 36% higher in 2060. This translates into a 90% increase in average wages (in adjusted, real terms) from today.

Sydney's affluent eastern suburbs have raw and untreated sewage from 3,500 people discharged directly into the Tasman Sea.
The Cape Grim observatory, home of the ‘world’s cleanest air’… and rising greenhouse gases.
Carbon dioxide levels in the atmosphere are at 414 parts per million. But thanks to a recalculation of methane's warming power, the total amount of greenhouse gases is now equivalent to more than 500.

Waves occur in all sorts of places, and it's possible that waves you might see breaking at the beach are at the end of a very long journey.
Sunset at Australia’s Cape Grim observatory, one of the key global background monitoring sites for CFC-11.
For several years, emissions of CFCs have been rising, in apparent defiance of a global ban in place since 2010. A new global detective effort has traced the source to two eastern Chinese provinces.
It’s not cows’ fault they fart, but the methane they produce is warming the planet.
Removing human-related methane from the atmosphere could reduce global warming by 15%.
