Drowned Out?

World sea levels are currently rising faster than at any time in the last 3,000 years. Humans are mainly located around the coasts of land masses. The UN Secretary General is consequently warning that circa one billion people are likely to be endangered by the rising waters of the oceans. (https://www.theguardian.com/environment/2023/feb/14/rising-seas-threaten-mass-exodus-on-a-biblical-scale-un-chief-warns). The UN Secretary General notes that rising sea levels damage lives, economies and infrastructure. Some countries may simply cease to exist, stimulating mass human migrations. Such forced migrations are likely to threaten global peace and security (just consider the current responses to modest human relocations). Yet again, the Secretary General appeals for all countries to slash their 'greenhouse gas' emissions. There seems to be little sign of a positive response to his entreaties?
