ScienceDaily (Oct. 2, 2012) — Greenhouse gas emissions up to now have triggered an irreversible warming of Earth that will cause sea levels to rise for thousands of years to come, new research has shown.

The results come from a study, published today (Oct. 2) in IOP Publishing's journal Environmental Research Letters, which sought to model sea-level changes over millennial timescales, taking into account all of Earth's land ice and the warming of the oceans -- something which has not been done before.

The research showed that we have already committed ourselves to a sea-level rise of 1.1 metres by the year 3000 as a result of our greenhouse gas emissions up to now. This irreversible damage could be worse, depending on the route we take to mitigating our emissions.
