Observations – based on paleoclimate data
Paleoclimate Observations
• The sea levels rose about 30 feet/ oF as the Earth warmed after the last glacial maximum6
• Based on the CO2 emitted to date (the atmosphere is currently at about 400ppm), we should plan for a sea-level rise of at least 45 feet.7
• Temperatures have varied about 1.8 over the last 10,000 years
