Extinction Rebellion

The UN IPCC 1.5 Special Report published October 2018 says rapid change is needed by 2030 – in other words – by twelve years from now. This is a call to individuals to participate in a coordinated response to the global & ecological climate emergency and International Rebellion this April.

We are inviting you to join an effort to raise the profile of our twelve-year timeline. We want to mark the number ‘12’ to help disseminate information about the timeline.

This is what happens. We will form into groups and arrange meeting points. You bring something to bang or ring, such as a small bell or a cooking pot and a spoon,, or an air-raid siren! A volunteer leads the group to chant from 1 to 12, while chanters simultaneously ring the bells and beat the pots. After number 12 is reached, there is a pause in the beating and chanting, so the group has a short rest, before the leader starts it up again. Members of the group bear signs about the climate emergency and our twelve year timeline, and engage with passers-by, handing out leaflets we will supply.

These group actions will take place during the start of International Rebellion on these days: April 15th – 17th anytime from early morning to late evening.

Wherever you are, please register your interest as soon as possible on this page (just click ‘going’ or post in the discussion). More details will be added about where and when to meet.

This event is part of International Rebellion from 15th April onwards.


“Climate change is now reaching the end-game… The issue is the very survival of our civilisation.” – Prof Hans Joachim Schellnhuber, for 20 years the Head of Potsdam Institute for Climate Impact Research, Senior Advisor to Pope Francis, German Chancellor Angela Merkel and the EU.

“The facts about our ecological crisis are incontrovertible. We must take action” say notable leaders including previous Archbishop of Canterbury, Dr Rowan Williams (Please read this published letter )

2019 is arguably our last chance to drive policy and culture change so as to achieve the ambitious targets set out in the UN’s IPCC 2018 report which describes the enormous harm that anything above a 1.5°C rise in global temperature would cause. It told us that limiting to 1.5°C may still be possible yet requires “rapid, far-reaching and unprecedented changes in all aspects of society”. The problem though: we’re not on track. Carbon emissions haven’t stopped rising and temperatures are heading towards 3°C. If we continue on our current course, future changes in climate could be dramatically abrupt and irreversible, seeing mass migrations, crop failures and unprecedented disasters. This is already putting a raft of other pressures on the ecology, with 200 species going extinct every day due to habitat loss as well as change in climate. In a 2018 study of British mammals it was found that 1 in 5 could be extinct within a decade. This is our time to alert those who do not know, to reinforce the twelve year window of opportunity, and increase ways to shift the global narrative and generate the necessary political will.
