The 0.8 metre sea-level rise value is based primarily on the median value of the RCP 8.5 greenhouse gas emission scenario which is ‘business as usual’ where the current rate in the growth of greenhouse gas emissions remains the same. Scientists are forecasting sea levels will rise between 0.4–1.1m over the remainder of this century depending on how rapidly the world reduces emissions of greenhouse gases.

This data has shown a more-or-less steady increase in Global Mean Sea Level (GMSL) of around 3.2 ± 0.4 mm/year over that period. The LiDAR data is being used to monitor shoreline change, beach erosion and accretion, and vegetation changes. It also considers the projected variation in the local sea-level rise rate of northern Australia. At a 60-metre rise, most of the USA's east coast appears to disappear underwater Credit: The Sun. Sea level is measured by two main methods: tide gauges and satellite altimeters. The LiDAR data has significantly improved the accuracy of sea level rise modeling in these countries and the ability to understand current and future risk to infrastructure and communities.
