If ocean levels are rising, why can’t we see it?
Compare two photos 130 years apart and it looks as though sea levels haven’t moved. So why all the fuss about rising sea levels and evacuating islands? This video closes the yawning gap between internet myths and science.
CORRECTIONS:
1) The shades of blue on the map at 10:58 denote sea level falling, not rising at the lowest rate..
2) I said glaciers cover around 10% or the Earth — I should have said 10% of the land surface of the Earth.
3) Two posters pointed out that Reiss’s question to Hansen could be taken to mean ‘What would the view be like in 40 years’ time if CO2 concentration was NOW double?” In other words, Hansen was predicting sea level 40 years AFTER a doubling of CO2.”
To be fair to Hansen, that’s possible. If so, his prediction will very likely be correct.
But it again stresses the need to have these predictions made in peer-reviewed scientific journals, where such ambiguity is eliminated, rather than books.
