Analyses and maps of sea-level rise impact

Colleagues at Climate Central have run US and global analyses putting the projected 6m of eventual sea level rise in a meaningful context.

Figure 1: Small increases in global average temperature may eventually lead to sea-level rise of 6 metres or more according to evidence from past warm periods in Earth’s history. Temperatures shown are relative to preindustrial levels. Present day temperature is around 0.8°C higher than preindustrial levels.
