The table shows information about sea level rise due to human-induced climate change.

(mm = millimetres).

Sea level rise in 2006 (mm)

Sea level rise in 2016 (mm)

40

80

Liam claims, “From 2016 to 2026 the sea level rise will increase by the same percentage as from 2006 to 2016.” He works out, 

Increase in sea level rise from 2006 to 2016 = 80 – 40

= 40

Sea level rise in 2026 = 80 + 40

= 120

Does the sea level rise of 120mm match his claim? Show your working.
