Pretty hard to accept 198 inches since NASA's own data shows no more than 250mm or 9.4 inches since 1888. You would have to assume there are no balancing factors. If the earth gets warmer then there is also more evaporation of the oceans which causes more rainfall which helps moderate temperature and moves oceanic water inland. I agree the climate is getting warmer but doubt that trend continues forever. History says it won't. Common sense says that in any closed system, things do not change exponentially forever. I really do need an answer to the question of why in certain years ocean levels were actually lower than the year before like 2010. I honestly want to know why that happens. Steven Naslund Chicago IL
Let's run the math. 1mm/additional per year. So 1 the first year, 2 aditional the second, ... and the century year then adds 100mm or 4 inches *by itself*. But we need to add years 1 to 99's contributions too...
sum(1..100) = 101 * 50 or 5050mm. Divide by 25.4 and you get 198 inches cumulative.
Be glad the actual rate of acceleration is less than 1mm/year.
