The forecast arrival of El Niño may mean the east coast of Australia will experience an exceptionally hot and dry summer, but does this mean there will be fewer mosquitoes buzzing about?
Maximum temperatures for January to September were the warmest on record for the Murray–Darling Basin and New South Wales.

Engineering practice assumes that floods are randomly distributed but science suggests they are not. This raises questions about the reliability of flood infrastructure and management strategies.
Climate change is raising global sea levels. Now research shows that ‘hot spots’ where seas rise another 4 to 5 inches in five years can occur along the Atlantic and Gulf coasts, further magnifying floods.
The growth in global carbon emissions has resumed after a three-year pause.

After three years in which global carbon emissions scarcely rose, 2017 has seen them climb by 2%, as the long-anticipated peak in global emissions remains elusive.
Cape Town’s drought and associated water shortage has escalated disaster level.

Cape Town promised alternative water sources with the ongoing drought being declared a disaster. Its main strategy is water rationing but climate models are also being used.
The dolphin population in parts of Western Australia more than halved one year, just as an El Niño event hit over in the Pacific. So what’s the connection?
The extent of future coral bleaching is likely to vary from place to place.

Regional variations in sea temperature can make all the difference between a coral reef suffering major bleaching or surviving as a refuge for corals, new research shows.
There have been successive large scale droughts in East Africa.

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.
