Sea level rise will become unmanageable at just 1.5C of global heating and lead to “catastrophic inland migration”, the scientists behind a new study have warned. The melting of those ice sheets would lead to a “really dire” 12 metres of sea level rise. Today, about 230 million people live within 1 metre above current sea level, and 1 billion live within 10 metres above sea level. Sea level rise of at least 1-2 metres was now inevitable, the scientists said. In the UK, just 1 metre of sea level rise would see large parts of the Fens and Humberside below sea level.
