An independent review has recommended that the UN peacekeeping mission in the Democratic Republic of Congo withdraw by 2022. The mission, established 20 years ago, is the UN’s largest field operation. Its remit has been to protect civilians and strengthen state institutions. Although it has brought some stability, violence and internal displacement continue, particularly in Eastern DRC, where over 100 armed groups are still active. Mats Berdal argues that if the withdrawal is rushed it will result in further instability and a recurring crisis.

Mark Maslin explains how to identify the different types of denial and spot the different ways that are being used to convince you to delay action on climate change.
