Australia is facing an above-average cyclone season, with at least 11 cyclones likely in the region.
China may be undertaking more cyber attacks than the Australian government has admitted.
It's no surprise that China represents a cyber threat to Australia. But the government has been reluctant to state this fact and needs to respond more decisively.
Galileo was right, but that doesn’t mean his fans are.

One Nation Senator-elect Malcolm Roberts lauds Galileo as a hero who turned scientific consensus on its head. But the 'Galileo gambit' is just one weapon in the climate conspiracists' arsenal.

Australia is surrounded by ocean, so is not immune to the effects of tsunamis. But how significant is the risk?
Tasmania’s Cape Grim monitoring station passed a crucial carbon dioxide threshold this month.

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.

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.

The summer of 2015-2016 was the hottest on record for Australia's oceans.
Nice day for the beach. In fact there have been rather a lot of those in Sydney lately.

Sydney is in the process of smashing the record for the longest run of days above 26℃. Weather, El Nino and climate change are all playing their part.
CSIRO’s decision a decade ago to merge its marine and atmospheric research set the stage for a national climate research plan.
CSIRO was instrumental in creating a unified plan for all of Australia's climate research. The latest round of cuts would see that collaboration fall apart.
It’s all a matter of perspective.

Former PM's business advisor Maurice Newman recently claimed that satellite temperature data tell a different story to data collected on the ground. He's right - but that's how it's meant to be.
Rural southern Australia has been drying out over the past several decades. Pictured here, Burra in South Australia.
Australia is the land of drought of flooding rains, driven by events such as El Nino. But despite this variability, some parts of Australia are clearly drying out.
Despite a decade of drought and declining rainfall in parts of Australia, there’s still plenty of water to go around.

The Millennium Drought ended more than five years ago, but several years of below-average rainfall and El Niño have brought drought back to many parts of Australia. Our latest report on water in Australia shows rainfall is continuing to decline in eastern Australia and increase in the north.

With El Niño upon us and the prospect of water scarcity ahead, how well positioned are we to make accurate and timely decisions about water resources?
This doesn’t happen very often. But the Bureau of Meteorology is getting much better at predicting when it will.

Moaning about weather forecasts is almost an Australian national pastime. But weather predictions have improved a lot, and with a new satellite and supercomputer, they are about to get even more reliable.

El Niño is officially here according to the Bureau of Meteorology.
Adjusted data from Australian weather stations has been peer-reviewed before. But the government’s new technical panel could still offer useful advice.
The federal government’s new “Technical Advisory Forum” on weather data, announced by parliamentary environment secretary Bob Baldwin last week, will “review and provide advice on Australia’s official…
What does Paraguay have to do with the global temperature record?
An article in The Australian today has once again raised the question of why scientists, in trying to estimate how the global and regional surface temperatures of Earth may have changed over the past century…

2014 has been confirmed as Australia’s third-hottest year, capping off a record-breaking decade, according to the Bureau of Meteorology’s annual climate statement, released today. Seven of Australia’s…
Nationals MP George Christensen told Parliament that the hot temperatures of 1896 have been “wiped from the official record”. It’s a bit more complicated than that.

“How could it be getting hotter … if it was really hotter 118 years ago? It’s relatively simple: the early years are simply wiped from the official record.” – Nationals MP George Christensen, House of…
