Since 1999, Australia has swung between drought and deluge with surprising speed, because El Niño has fallen into sync with similar patterns in the Indian and Southern Oceans.
The odds of being hit again by a large flood are higher for cities that have already been flooded before. Here's why we still don't move away.
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.
Climate change makes extreme weather more likely – but we also have the power to make our flood responses smarter.

CSIRO's climate science has contributed a number of important, and unexpected, findings.
Reflecting on flood insurance
Insuring the most at-risk homes should become easier after April, but the latest deluge makes the new scheme look fragile.
Cumbria 2015 shows how we have failed to learn from two other 'one in 100-year events' in the past 15 years.
We accept the risks of flooding because the costs of making our towns and cities flood-proof are too high.
While firefighters battled widespread fires in New South Wales in October 2013, hundreds of thousands of people turned to social media and smartphone apps for vital updates.

When disaster strikes, more people than ever are turning to social media to find out if they're in danger. But Australian emergency services need to work together more to learn what works to save lives.
People in the Philippines have been warned to brace for wet and wild weather, as this year’s El Nino shapes up to be the strongest since 1998.

The seesaw between El Niño and La Niña is set to get stronger with global warming. Signs are that this year and next will deliver a big swing from one to the other, prompting fires and floods across the world.
Levees in New Orleans were unable to prevent flooding during Hurricane Katrina in 2005.
Delta cities in both rich and poor countries face uphill, and potentially costly, battle in containing risk from flooding.
Go with the flow: scarce water has allowed Outback species to persist for millennia, where otherwise they might have died out.
The Outback covers 70% of Australia, and its water is precious and scarce. Yet there is no joined-up plan to monitor and manage Outback water, despite the wealth of species and communities that depend on it.
There are more resilient ways to build in vulnerable areas.

The climate is changing. Development patterns that have hardly served us well in the past certainly won't serve us well in the future. Now is the time to adapt.
Cars remain submerged on a road in Texas after torrential rains caused massive flooding.
The National Flood Insurance Program – the only source for flood-prone property protection – is drowning in debt.

A new database of UK coastal flooding will help prevent future disasters.
Drought-reduced crop yields could threaten food supply in Australia.
The Australian Academy of Science has warned that sick, older, poor and isolated Australians are at most risk from the health impacts of climate effects such as drought, fires, floods and heatwaves.
Recent extreme rains such as those that hit Sydney recently are actually decreasing, but extreme rain in summer is going up.
