Intelligent machines are getting better at understanding our conversation.
Human communication is complex, rich in nuances and frequently includes non-verbal signs. That's a challenge if you want an intelligent machine to be part of the conversation.
Tasmania’s Cape Grim monitoring station passed a crucial carbon dioxide threshold this month.
Bureau of Meteorology
Atmospheric carbon dioxide measurements at Tasmania's Cape Grim and Antarctica's Casy Station have now officially passed 400 parts per million and are likely to stay above that for decades to come.
Moo-ve along: livestock are one of many threats to Australian freshwater ecosystems.
Freshwater covers only 0.5% of the Earth's surface but is home to 10% of the world's lifeforms.
The Solomon Islands are low-lying and vulnerable to changes in sea level.
Sea levels are rising faster in the Solomon Islands – and send a warning for the rest of the world.
Green planet: tropical rainforests have produced more growth in response to rising carbon dioxide.

Half of the world's vegetated land has got greener in the past 30 years, mostly driven by rising CO2.
Data about farms' financial situation as well as the weather could help identify those most vulnerable to drought.
Forecasting drought should be about more than weather – to help those likely to be hit hardest, we need financial and even health data too.
Tasmania’s bushfires damaged pristine bushland and stretched emergency services to the limit.

This summer has seen Tasmania suffer through drought, bushfires, floods and the worst marine heatwave on record. Is this what life under a climate-changed future will be like?
Glacier melt is one of the major contributors to global sea level rise.

Global average sea level has risen by about 17 cm between 1900 and 2005, but we didn't know how much of that was due to us, until now.

A proposal for the Bureau of Meteorology to take on CSIRO climate scientists is a good idea - but CSIRO needs to make sure nothing is lost.
Glaciers have been a major contributor to sea-level rise.
Could sea levels really rise by several metres this century. Probably not, although this century's greenhouse emissions could potentially set the stage for large rises in centuries to come.
Farming land in New South Wales.
Growing population, growing demand for food, climate change: Australia's rural lands are facing a number of pressures. So how can we sustainably use them in the future?
A diet like this isn’t particularly good for your waistline – or the planet.

Climate change will make it harder to eat healthily.
Livestock ‘digestion’ produces nearly 3 billion tonnes of greenhouse gases each year.

Eating less meat isn't the only solution to reducing greenhouse gas emissions from livestock.
Rice cultivation is one of the ways food production pumps methane into the atmosphere.

Fossil fuel emissions are slowing, but another major climate problem is becoming clear: food production.
A study in resilience.

Markets have been on a rocky ride all year on concerns another recession looms. Here are a few lessons we can learn from the last one.
The southern black-throated finch could be brought to the brink by coal-mining developments.
More than half of the remaining habitat for Queensland's southern black-throated finches is potentially subject to mining development. If these mines go ahead, it will be bad news for these birds.
Fungus gnats are one the many arthropods that find their way into our homes.

Our homes harbour hundreds of species of insects and their relatives.
We still don’t know enough about questions such as where the tipping points are for Arctic ice melt.

The Paris agreement has given us some solid targets to aim for in terms of limiting global warming. But that in turn begs a whole range of new scientific questions.
Leatherwood flowers give Tasmanian honey its unique taste.
Tasmania's bushfires have hurt not only the state's forests, but also the honey industry that depends on access to the region's unique trees.
Plastic fragments found in dissected fish.

Dave West from the environmental group Boomerang Alliance told Fairfax that if you've got an average seafood diet in Australia, you're probably ingesting about 11,000 plastic pieces a year. Is that right?
