The 2022 Hunga Tonga volcanic eruption produced the equivalent of 60,000 Olympic swimming pools of water vapor, which ended up in the stratosphere. Researchers have studied its impact on climate and suggest that it could lead to unusual winter weather for years to come.

Working with Uncertainty in Climate Planning and Adaptation

Climate model simulations offer us information about possible future outcomes with varying degrees of uncertainty. Understanding uncertainty in climate projections is vital for making more informed decisions and planning adaptation responses.

Floating robots reveal just how much airborne dust fertilises the Southern Ocean – a key climate ‘shock absorber’

Researchers have found that windblown dust delivers enough iron to support a third of the Southern Ocean’s phytoplankton growth. This finding sheds light on the vital role that dust-fuelled productivity plays in the ocean's capacity to absorb and store carbon dioxide from the atmosphere.

Why did rainfall increase in the third year of the recent triple-dip La Niña?

It seems counterintuitive that rainfall increases in the later years of a multi-year La Niña event. Yet, this is what occurred during the recent triple-dip La Niña. Even more interestingly, this increase happened despite no strengthening of La Niña in the tropical Pacific. So, what's the reason behind it?

The heat is on: what we know about why ocean temperatures keep smashing records

To us, a warmer ocean might feel pleasant. But the extra heat manifests underwater as an unprecedented series of major marine heatwaves, which can lead to mass death or mass migration for marine mammals, seabirds, fish and invertebrates and cause widespread coral bleaching.
