Scientists warn of irreversible climate impacts threatening coastlines and oceans

A new study warns that despite climate initiatives, the melting of Greenland and Antarctic ice sheets is accelerating, leading to rising sea levels that threaten coastal communities worldwide, with potential irreversible impacts on human timescales. The study emphasizes that even a 1.5°C temperature increase could cause several meters of sea-level rise over centuries, and current efforts may not be enough to prevent catastrophic consequences.
