The COP23 climate change summit in Bonn and why it matters

Halting dangerous global warming means putting the landmark Paris agreement into practice - without the US - and tackling the divisive issue of compensation

The world's nations are meeting for the 23rd annual "conference of the parties" (COP) under the UN Framework Convention on Climate Change (UNFCCC) which aims to "prevent dangerous anthropogenic interference with the climate system", ie halt global warming. It is taking place in Bonn, Germany from 6-17 November.
