International cooperation is critical for developing countries and vulnerable regions to achieve the challenging target of limiting global warming to 1.5 degrees Celsius. Before this, the capacities for climate action of national and sub-national authorities, civil society, the private sector, indigenous peoples and local communities need to be strengthened. Poverty, inequality and disadvantage are expected to increase with global warming. Impacts on ecosystems will be mitigated at the 1.5 mark. This would also slow down the rate of sea level rise. Meaning, there would be greater opportunities for adaptation in the human and ecological systems of small islands, low-lying coastal areas and deltas. The world is already being affected by global warming. Climate change has already begun to cause destruction. Given this, long-term planning and implementation of national policies that mitigate and factor in the adverse effects of global warming and potential human displacement, are urgently required. Southeast Asian states are no exception. The more unprepared states are, the more the human displacement!
