The coral reef of Rarotonga helped scientists create a better climate history.
El Niño events can affect millions of people around the world, causing drought in Australia and floods in the Americas.

A combination of reasons have led to the drying of the Sahel.
Vegetable prices are on the rise. How can Canadians cope?
Canada’s Food Price Report, recently published by Dalhousie University and the University of Guelph, predicts significant price hikes for vegetables this year.

With the dire consequences of climate change looming, archaeologists recognize the importance of communicating their findings on ancient landscapes and the threats that face vulnerable populations.
In Zambia businesses in the food processing sector, are in for a tough time.
Water and power cuts prompted by reduced rainfall and drought in Southern Africa have caused major problems for business.
Queenslanders have taken to the water in the face of record-breaking heat.
The summer forecast from the Bureau of Meteorology predicts a hot, dry summer.
A hot summer will mean wetlands dry out faster than ever, so how will pest mosquitoes respond?

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.
After the warmest month on record, it looks like Australia will have an El Niño event – which means the drought is likely to continue.
Much of Australia is set for a hot April.
Record-breaking April heat is likely to continue for at least another month.
It’s more important to know whether there’ll be any weather than what the weather will be.

The Bureau of Meteorology's climate outlook for April to June is 'neutral', but that doesn't mean we're flying blind, weather-wise.
Floods in South East Queensland follow a 40-year cycle, and planners should take note.
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.
A survey of recent global trends in temperature and rainfall – and a lesson for Mr Trump on the difference between weather and climate.

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.
Leaping bottlenose dolphins.
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.
It's very easy to assume climate change causes droughts, but they are complex extreme events that result from a combination of drivers.
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.
