Sea levels could be up to 4.9 feet (1.5 metres) higher than scientists previously thought, a new study has warned, putting millions more people at risk from rising oceans. By comparison, 11 inches of increase is greater than the total sea level rise that has occurred since the beginning of the 20th century. Scientists say that global sea levels could rise up to 3.2 feet (one metre) higher than scientists previously thought, putting millions more homes underwater. Previous research has underestimated how high sea levels already are in the UK by at least 11.8 inches (30 cm). This means sea level rise will lead to more damage than previously thought.
