Surprisingly accurate nautical maps created the 17th to 19th centuries strongly suggest coastal land area in both hemispheres were quite similar to today’s. There is even evidence relative sea levels were higher than now back then.
Globally, coasts have grown since the 1980s
Between 1985 and 2015, satellite observations indicate the world’s coasts gained 13,565 km² more land area than they had lost to the seas (Donchyts et al., 2016).
This means more coastal land area is above sea level today than in the 1980s.
This surprises scientists, as they “expected the coast would start to retreat due to sea level rise,†but instead they observed “coasts are growing all over the world.â€
Duvat (2019) also identified a global trend in island shoreline net growth since the 1980s despite recent sea level rise, as none of the globe’s islands larger than 10 ha – and just 1.2% of the 334 islands larger than 5 ha – have decreased in size since the 1980s.
These recent trends would appear to be the opposite of what would be expected with modern global warming.
