Earth’s Surface Gaining Coastal Land Area, Despite Sea Level Rise

Watts Up With That?

Guest post by David Middleton


Earth’s surface gained 115,000 km2 of water and 173,000 km2 of land over the past 30 years, including 20,135 km2 of water and 33,700 km2 of land in coastal areas.

Nature Climate Change

173,000 km2 – 115,000km2  = 58,000 km2

33,700 km2 – 20,135 km2 = 13,565 km2

If sea level is rising, how did Earth gain 58,000 km2  of net land surface area, including 13,565 km2 of net coastal land surface area?  I’m sure that there is an obvious logical answer.    The Cretaceous sea level was about 50 m higher than today and land comprised only 23-26% of Earth’s surface area (vs 29% today).

This BBC article goes into a bit more detail and sort of answers my question…
