After three long years of rainy weather, La Niña is over. But that doesn’t mean El Niño is a certainty. Here’s why.
We can now monitor coastal changes across thousands of beaches over the last 40 years, from Australia, New Zealand and Japan, to Chile, Peru, Mexico and California. Here’s what our new tool uncovered.
On Australia’s rainiest days, more than 30 trillion litres can fall from the skies.

A climate scientist explains the forces behind the summer’s extreme downpours and dangerous heat waves, and why new locations will be at risk in the coming year.
By following moisture from the oceans to the land, researchers worked out exactly how three oceans conspire to deliver deluges of rain to eastern Australia.
After one La Niña, the Pacific sometimes retains cool water which enables a second La Niña to form.

The NSW floods are a textbook example of the theoretical impacts we can expect on Australian rainfall as climate change continues.

A new statistical model predicts the number of tropical cyclones up to four months before the start of the season from November to April.

It’s only happened twice since naming started in 1950, and there’s an unusual twist to where many of the storms formed this year.
Tropical cyclones account for almost four in five natural disasters across Pacific Island nations. But a new forecasting tool now gives up to four months warning for the upcoming cyclone season.
Warmer temperatures could lead to more zones of the country that make good breeding sites for mosquitoes.

Is our changing climate making regions of the US more suitable for ticks and mosquitoes that spread diseases? Or is the climate changing human physiology making us more vulnerable?

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?
Climate change is already delivering more extremes of wet and dry to the Pacific region.

New research shows that global warming has already begun to exacerbate extremes of rainfall in the Pacific region – with more to come.
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?

February 2016 was the hottest month by the biggest margin ever. Does that mean global warming has gone into hyperdrive?

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 land may be dry, but Western Australia’s waters are full of life.
The Great Barrier Reef might get all the attention, but what about our western coral reefs? Warmer waters and human impacts mean these reefs are in trouble.
Australia’s weather is influenced by warm water movements in the Pacific.
We wait in anticipation of droughts and floods when El Niño and La Niña are forecast but what are these climatic events? The simplest way to understand El Niño and La Niña is through the sloshing around…
Whither the weather: the Bureau of Meteorology’s dynamic climate modelling is not the only forecasting method.
Over the last two summers, Eastern Australia has experienced two of the hardest hitting La Niña events since 1974. Widespread floods resulted across great swaths of the country. As expected, the La Niña…
We’re just coming to grips with Interdecadal Pacific Oscillation, one of the many climate modes that cause Australia’s wide and wonderful range of climate variability.
While most people now understand that the enhanced greenhouse effect means a much warmer planet, communicating regional shifts in weather remains a significant challenge. As with most complex science…
