It’s not just ocean temperatures that determine whether we have El Niño or La Niña. Air circulation also plays a role, and it’s changing in unexpected ways.
A natural weather event known as El Niño is underway in the Pacific Ocean.
An El Niño weather-warming phase is underway in the Pacific – but what does this mean for the weather in Europe?
The Indian Ocean’s heat is having effects on land, too.

Drought in Europe, dwindling Arctic sea ice, a slow start to the Indian monsoon – unusually hot ocean temperatures can disrupt climate patterns around the world, as an ocean scientist explains.
2016 was the world’s warmest year on record, due in part to a very strong El Niño event. But 2023 (and 2024) could beat that record – what should we expect?
Potatoes are profitable and in demand. But wet weather and hard-to-control diseases have caused havoc for our growers.
The research help us understand how El Niño and La Niña will change as the world warms in the future.
There’s a 98% chance of a record hot year by 2028, and a 66% chance of exceeding the 1.5°C threshold for at least that year, according to the latest World Meteorological Organization update.
Black Summer smoke.
Where there’s fire, there’s smoke – could plumes from the Black Summer of fire have cooled regions of the Pacific and triggered a La Niña? New research suggests it’s possible.
Marine heat waves can reach the ocean floor as well as surface waters.

El Niño can trigger intense and widespread periods of extreme ocean warming known as marine heat waves. They can devastate marine life.
Last year was great for plant growth and river flows. But Australia is still on the brink of losing a slew of plant and animal species.
Not all La Niñas are wet, nor El Niños dry – especially if you live in Sydney. So here’s how to interpret what an El Niño forecast means for you.
After three long years of rainy weather, La Niña is over. But that doesn’t mean El Niño is a certainty. Here’s why.
El Niño was given its name by Peruvian fishermen.

The Pacific Ocean climate pattern is the opposite of El Niño.
Not all El Niño events lead to drought in Australia. Other factors are involved and it will take some time for drought to develop now catchments are wet and most dams are full.
The UK had its first storm in a year last weekend.

An expert explains why the UK’s winter has been relatively calm.
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.
As with so many staples and foods in the past two years – lettuce, milk and eggs to name a few – the problem is a temporary imbalance between supply and demand. Here’s what’s happening with potatoes.

The latest Bureau of Meteorology forecast offers relief from record rain and floods brought about by La Niña. A longer-term outlook for El Niño is still up in the air – but its arrival would be disastrous.
Globally, the air is getting hotter and drier, which means flash droughts and risky fire conditions are developing faster and more frequently.
England may flood in February.
The Met Office has predicted that England is to be affected by flooding this February.
