Deforestation, Land- Usie Changes, andCoastal Development

Deforestation indirectly akcelerates sea level rise reducing thee Earth 's capacity to absorb atmosferic CO comexyb, thereby intensifying global warming.

Natural Processes Influencing Sea Level Changes

Beyond 2100, sea levels will continue rising for century s due to te inertia of ocean warming and ice sheet melting. Even experate cessation of emissions would nott halt thermal expansion and ice loss, which operate on multi- decadal to millennial timesclesles. This long-term commissiment to rising seas highlighs the urgent need for both emissions compationiation and adaptiva planning.
