Hurricane Matthew approaching the east coast of Florida on Oct. 6, 2016.
Two atmospheric scientists explain how they weigh evidence such as ocean temperatures, wind speeds and other climate patterns to predict how many Atlantic hurricanes are likely to form this year.

Cholera kills thousands every year but is treatable if it is caught early. Understanding how El Niño shifts cholera risks in Africa can help countries prepare for outbreaks and save lives.
The tropical Pacific has a large say in how fast the world warms.
If the Pacific Ocean enters an 'El Tio' phase, it could speed the world towards 1.5 degrees of global warming, one of the crucial benchmarks of the Paris Climate Agreement.
This year’s bleaching has mainly affected the Great Barrier Reef’s central region.
For the first time the Great Barrier Reef has been hit by mass bleaching in consecutive years, with only the reef's southernmost stretches having escaped both events unscathed.

New research shows that global warming has already begun to exacerbate extremes of rainfall in the Pacific region – with more to come.
Firefighters fight forest fire in Indonesia, triggered in part by El Nino.
We’re due to cop a hiding from the Pacific Ocean, but we don’t know when.
Surf’s up: September storms brought waves, wind and flooding to South Australia.

2016 was Australia's fourth warmest year on record, capping off the hottest decade.
In Darwin the wet season usually arrives around Christmas Day.

The Australian monsoon delivers most of northern Australia's rainfall and is a vital feature of life in the region. But why does it occur?
Warmer temperatures are likely to cause heat stress in cattle raised on natural pastures and in feedlots.
Drought is a massive problem for southern Africa. The region requires adaptation and mitigation strategies if it's to cope with the changing climate.
You can only truly understand the weather by flying above the clouds.
Far from being "politicised science", as a Trump advisor has claimed, NASA's satellite monitoring has been a crucial help in understanding the planet we live on.
Residents of Collaroy, NSW, got a painful lesson in the power of the ocean in June.

Many Australians live on the coast, but how much do we know about the risks? While average sea levels are relatively easy to gauge, the risk of flooding also depends on weather, landscape, and climate.
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.
Looks like paradise – but how did the first people get there?
Global Environment Facility
Researchers ran computer simulations that take into account environmental variability and geographical setting to investigate how early explorers made it to these tiny, remote islands in the Pacific.
Australia’s had a cooler and wetter winter, but the rest of the world has been hot.

Since April 2015, each month has been the hottest on record and it's the longest hot streak on record.
Climate change and the current El Niño have left Africans more vulnerable than ever to hunger.
Economic growth alone won't end hunger. Good policies and programmes are needed, too. Scientists and researchers have a role to play in these initiatives.
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.
Fields showing little signs of plant emergence at a late stage of the season, indicating a near total crop loss in Zimbabwe.
Satellite rainfall data can be used to predict harsh climate events – and to identify food-insecure populations before disaster strikes.
Summer stayed into autumn in many parts of Australia.

Autumn 2016 was Australia's hottest, beating the previous record set in 2005.
Eventually reduced rainfall hit much of Australia thanks to El Niño.
From floods to drought, fire to famine, the 2015-16 El Nino has had a global impact.
