New research shows that older people are especially at risk during and after natural disasters, and may need medical help or other support well after relief operations end.
Analysis of flood gauge data suggest that floods are becoming less frequent in many parts of the world. Despite that, more people and property are at risk, particularly in developing countries.
Global warming of 2℃, the higher of the two Paris targets, would see current record-breaking temperatures become the norm in the future, potentially bringing heatwaves to both land and sea.
The record floods of 1954 and 1974 still stand as Lismore's high-water marks. But Tropical Cyclone Debbie delivered her deluge far more abruptly than the rains that triggered those historic floods.
Research based on palaeological flood records suggests floods as big as those that hit Brisbane in 2011 may be more common than we think.
2016 was Australia's fourth warmest year on record, capping off the hottest decade.
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.
Floods are often seen as a force of destruction. But as river ecologists, we find it hard not to rejoice at the flooding.
The current climate talks in Morocco are a golden opportunity for making strides on the adaptation of African agriculture. African countries need the tools necessary to do so.
Floods are a costly part of Australian life, which means we need to get better at predicting exactly when - and how severely - they are likely to strike in the future.
Researchers have found a disaster "hotspot" in northern New South Wales, where nearly half of the state's most disadvantaged communities are found.
There are ticking time bombs, high up in the mountains.
A comprehensive analysis of Tasmania's natural disaster risks has identified bushfire as the biggest threat, alongside emerging issues such as disease epidemics and heatwaves.
The Grampians, like much of Australia, has swung from Millennium Drought to Big Wet and back again, putting animal populations on a rollercoaster that could get worse as climate change bites.
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.
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.
Storms like those that lashed Australia's east coast flush pollution out to sea.
A total of 1,859 people have died in floods in Australia in the past 115 years.
