Extinction Rebellion have floated a small house down the River Thames to draw attention to rising sea levels.
The group's latest demonstration, called 'Our house is flooding', featured a suburban house appearing to sink in the water near Tower Bridge, with one of the climate change activists positioned on top of it.
The climate activism group said it represented “the disastrous realities of projected sea level rises” and described it as an “attempt to send an SOS to the government on climate inaction”.
Katy Burak and Rob Higgs, who came up with the sinking house stunt, said: "We want to respectfully raise awareness of the severity of the impending human-made disaster”.
It comes after much of northern England was hit by major flooding caused by heavy downpours and burst river banks.
The body of a woman was recovered in Derbyshire last week, having apparently been swept away by the torrents of water.
At its worst, more than 100 flood warnings were in place with six labelled severe “danger to life”.
Extinction Rebellion said the extreme weather “starkly illustrated, our homes, businesses and families are at very real risk”.
It added: “We are watching, in real-time, as people’s lives are destroyed around the world and in the UK.”
Last month, the organisation took to the streets of the capital to demand immediate action on environmental issues.
The “Autumn Uprising” brought the capital to a standstill, with roads and bridges being blocked, as well as demonstrations on the London Underground and at City airport.
The Metropolitan Police attempted to curb the disruption by enforcing a London-wide ban on the demonstrations; however, a High Court last week ruled that this was unlawful.
