Climate-driven disasters are a driver of global internal displacement, and those who have contributed least to the climate crisis are affected the most. Every second, one person is displaced by an extreme climate disaster such as floods, storms, cyclones, droughts, fires, landslides and extreme temperatures. The number of people in need of humanitarian assistance is expected to grow exponentially in countries threatened by climate change. Those who have contributed least to the climate and environmental crisis are the most affected and the least prepared to respond and adapt to climate shocks and hazards. This is the background to the meeting of 40,000 delegates, including heads of state and world leaders, at COP28 in Dubai between November 30 and December 12. They will be there to build consensus and facilitate progress on climate change mitigation.
