Recent floods in southeast Louisiana were the most severe U.S. natural disaster since 2012's Hurricane Sandy. Suburban sprawl and slow execution of flood control projects worsened the damage.

Most people in Australia's southeast are familiar with the stormy weather known as East Coast Lows. But they might not realise how much scientific progress has been made in understanding them.
Cataclysmic natural disasters frame indelible human stories.

New research suggests a mythical flood in China really happened about 4,000 years ago. It's the latest case of scientists matching ancient tales to actual local natural disasters.

Wild seas have left beaches eroded and houses close to collapse.
Stormwater may be a road hazard, but it can also harm marine life when it flows out to sea.

Storms like those that lashed Australia's east coast flush pollution out to sea.
Most people die in floods when they choose to go into the water.

Eastern Australia's massive storms will likely become rarer in a warmer world, but probably more intense.
Could this become a regular occurance?
Cities' metros and subways are threatened by rising flood risks but innovative engineering could protect them.
The past century hasn’t seen the worst drought that Australia’s climate can throw at us.
A new millennium-long record reveals that Australia has suffered longer droughts and wet periods than those recorded in the past century's weather observations.
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?
Things got very wet, very quickly, in Brisbane in 2011.

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.
