Coastal cities will fall below sea level if warming hits 3C
Cities with hundreds of millions of inhabitants are at risk of being submerged by rising seawater if the United Nations’ (UN) latest warning on global warming is correct, according to analysis by The Guardian. Earlier this week, the UN disclosed that the world was headed for 3C of global warming. The Guardian has analysed data from the Climate Central group of scientists to show that such a temperature increase would result in irreversible sea-level rises of up to two metres. Cities including Alexandria, Miami, Osaka, Rio and Shanghai would be among the worst affected.
The UNEP Emissions Gap Report (EGR) series tracks our progress in limiting global warming well below 2°C and pursuing 1.5°C in line with the Paris Agreement. Since 2010, it has provided an annual science-based assessment of the gap between estimated future global greenhouse gas (GHG) emissions if countries implement their climate mitigation pledges, and where they should be to avoid the worst impacts of climate change. Each year, the report also highlights key opportunities to bridge the emissions gap, tackling a specific issue of interest. With the aim to inform the climate negotiations among UN Member States, the EGR is launched every year ahead of the UN Climate Change Conference of the Parties (COP). The EGR is co-produced by UNEP, the UNEP Copenhagen Climate Centre (UNEP-CCC) and partners.
