Metropolitan Police officers prepare to arrest a climate activist from Extinction Rebellion who had occupied a road around Parliament Square during a Back The Bill rally on 1st September 2020 in London, United Kingdom. Extinction Rebellion activists are attending a series of September Rebellion protests around the UK to call on politicians to back the Climate and Ecological Emergency Bill (CEE Bill) which requires, among other measures, a serious plan to deal with the UK’s share of emissions and to halt critical rises in global temperatures and for ordinary people to be involved in future environmental planning by means of a Citizens’ Assembly.
