Very powerful, try to avoid.
Lightning strikes are powerful – but we haven't had solid estimates of their energy until now. Researchers turned to the hollow stone tubes they create by vaporizing sand for more precise calculations.
Dry period in semi-arid central Australia.
Extreme wet years are getting wetter and more common. This means Australia's terrestrial ecosystems will play a larger role in the global carbon cycle.
Climate change can cause higher pollen counts.
Irrespective of whether climate change contributed to the thunderstorm in Melbourne last week, we can be sure Australia’s climate projections herald new risks to health that cannot be ignored.
The higher the plume, the bigger the problem.

When a bushfire rages so high it creates its own thunderstorm, it becomes a 'firestorm' - and makes life much more difficult for firefighters. We still have a lot to learn about what triggers them.
More heatwaves in store, but the exact effects on people are harder to predict.

Heatwaves are Australia's deadliest type of natural disaster. But while we know a lot about the weather patterns behind them, more research is needed to forecast accurately their impacts on people.
When New South Wales burned in 2013, Tony Abbott was quick to point out that individual events can’t be attributed to climate change. But they can.

The science of attributing extreme weather events to human-induced climate change has evolved rapidly in recent years. But how we communicate it to the public has not kept pace with this advance.
Australia’s oceans are heating up.
The new State of the Climate report outlines Australia's rising temperatures and its regional rainfall declines - and the trends that are locked in for the coming few decades due to greenhouse emissions.
Hurricane Wilma in 2005 was the last major storm to rock Florida – and its insurance market.
Even though Hurricane Matthew has been downgraded to category 3, it's expected to cause substantial damage to Florida and other states in the region. The question is, who pays.
Atmospheric, marine, environmental, biological and medical scientists join in calling for more focus on the damage being wrought by climate change.
Half a degree could make all the difference for the Great Barrier Reef.
A new report published by the Climate Institute says Australia could avoid lengthy heatwaves and help save the Great Barrier Reef by meeting the Paris Agreement's 1.5C global warming goal.
Victoria was one of several states to suffer bushfires as temperatures soared in late 2015.

2015 was the world's hottest year on record. The US State of the Climate report has rounded up the litany of temperature and other records that were broken all over the globe.
Flooding in Houston, April 18, 2016.
Extreme weather has an outsized impact on everyday life. Focusing on average weather patterns may make Americans dangerously complacent about how climate change is already affecting our lives.
Some materials and surfaces radiate much more heat (red areas) than others, as can be seen in this thermal image of Arncliffe Street in Wolli Creek, Sydney.
Hot spots occur at the scale of where people live – the building, the street, the block – which means urban design and building materials have profound implications for our health and well-being.
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.
Extreme weather could trigger ecosystem collapse, including mass tree deaths.

Extreme weather will affect people and animals, as well as whole ecosystems. Research using satellites shows that ecosystems worldwide are vulnerable to collapse.
Hurricane Sandy was a turning point on views about climate change, but the effect doesn’t trump political views.
Despite what some climate advocates think, extreme weather events do little to sway Americans' political views on climate change.
CSIRO has contributed to surprising discoveries in climate science. Pictured here is the research ship RV Investigator.

CSIRO's climate science has contributed a number of important, and unexpected, findings.
Changes in ocean temperatures are driving unusual weather patterns across Europe.
Hurricane Pali churns over the eastern Pacific on January 11.
NASA Earth Observatory
January hurricanes are rare events, but two have already formed this month. Atmospheric scientist Adam Sobel explains the conditions that generated Pali and Alex.
Hurricane Patricia as it made landfall on the Pacific coast of Mexico.
False complacency: Hurricane Patricia didn't devastate Mexico as feared, but provides more evidence that warming waters raise the chances of more intense storms.
