After record heat, could the Atlantic make Britain's weather even more extreme?
Scientists are using robotic probes in the Atlantic Ocean to monitor the Atlantic Meridional Overturning Circulation (AMOC), a system of currents that influences global climate. There is ongoing debate regarding how climate change is weakening this system and the potential impact on weather patterns in the UK and Europe.
Why it matters
The stability of the AMOC is critical for predicting future climate risks and extreme weather events in the Northern Hemisphere.

It is roughly the size of a person, with a tough metal body and an array of sensors packed inside.
The float is part of a global effort to solve one of the great mysteries of the ocean: how its hidden movements help shape the climate above.
There is no crew, no one steering it. Instead, it drifts with the currents, measuring temperature, the amount of salt in the water and pressure as it moves through the waves.
