England and France attempted to plant colonies in the Americas in the 16th century, but these failed. England and France succeeded in establishing permanent colonies in the following century, along with the Dutch Republic.
If all of the Earth's ice sheets and glaciers were to melt, sea level could be up to 265 feet (80 meters) above current mean sea level.
This suggests that about 1 foot of global sea level rise by 2100 is probably a realistic low end. On the high end, recent work suggests that 4 feet is plausible. , , , , In the context of risk-based analysis, some decision makers may wish to use a wider range of scenarios, from 8 inches to 6.6 feet by 2100.
