 2021 has been dominated by disasters and climate change. Sea level rise, droughts, tropical storms, earthquakes and flooding, having severe impacts on people's lives. In 2020, over 30 million people were forced to leave their homes due to disasters. If we do not take any meaningful climate action, over 200 million people could become internal climate migrants by 2050. Ahead of the 2021 UN Climate Change Conference COP26, we need to govern international action to minimize the impacts of disasters and climate change on human mobility. On the International Day for Disaster Risk Reduction, I join with other UN leaders to underline that only together can we achieve our common goals. The solution to the climate challenge is international cooperation. Building on three decades of operational and policy work, IOM works with humanitarian development and climate partners to respond to the mobility dimensions of disasters and climate change. This includes global, national and local partnerships, such as the Capacity for Disaster Risk Initiative and the Platform for Disaster Displacement. We must continue to cooperate to reduce socioeconomic losses from disasters and climate change. Resilience can only be built with communities to ensure that really no one is left behind.
