Several hundred school children dressed in blue are expected to take part in a 'die-in' today (April 12) in King's Parade.
The protesters will dress in blue to highlight the impacts of flooding and rises in sea level on future generations and marginalised communities in the developing world.
Protesters will be joined by University students, parents and adults in the themed demonstration, with the bells of Great St Mary's set to sound the alarm to signal the start of the die-in.
Demonstrators will lay on the ground for a total of 11 minutes, which represents the findings of a recent IPCC report, stressing that we have just 11 years left to avoid catastrophic climate change if we carry on with current emission levels.
The protest will be the third Friday's for Future protest that Cambridge has seen in the last three months, demanding urgent action be taken on climate change.
The movement, inspired by Greta Thunberg, has gathered worldwide momentum, as more than 1.6 million children took to the UK's streets on March 15, including hundreds here in Cambridge .
Cambridge Schools Eco-Council, the local children's organisation behind the strikes, said: "We have inherited a system which fuels the climate crisis that is threatening our future.
"We have done little to contribute to climate change, and yet we are going to suffer the consequences of it. Equally, the poorest children on Earth are nowadays suffering the worst impacts of a climate crisis that has been fuelled by the economy of the richest countries."
They went on to say: "This is a climate emergency. Our Youth Strikes will continue until government takes notice and urgently acts to stop funding, subsidising and promoting fossil fuels, invests in community-owned renewable energy and includes the environmental crisis in our schools curricula.
"We demand system change, we demand climate justice."
The day of action started at Shire Hall, where students were joined by Rowan Williams, former archbishop of Canterbury and Master of Magdalene College, for a lesson on different aspects of climate change.
Protesters are set to march down Castle Hill and Trinity Street at 11am before arriving at King's Parade for the die-in and speeches.
