UPDATE: Sea-level rise near the coasts where people actually live is found to be 1.69 mm/yr.
But when crunching the data for the entire ocean, as Willis Eschenbach has shown, a figure of just 1.52 mm/year is computed.
Hotshot data analyst Zoe Phin at her site examines sea level rise.
There she notes, “Climate alarmists are worried that the sea level is rising too fast and flooding is coming soon. You can find many data images like this on the net:”
Lately, the sea level has been rising 3.2 mm/year and some scientists say the rise is accelerating.
At her blog, Zoe points out that this is the rate measured by satellite for the entire ocean. She says what’s really important is the rate of rising along the coasts where it really matters for humans.
Examined data for grids adjacent to the coast
So she crunched the massive data volume for the surfaces near the coasts, downloading over a gigabyte of 720×361 gridded data covering 1950 to 2009.
She wrote: “I only examine those grid cells that are adjacent to land (2808 out of 259920).”
From her analysis, she produced the following table and computed the rise for the seas near land.
Thus the coastal trend is thus just half the total ocean trend claimed by scientists and the media.
Zoe’s findings agree nicely with tidal gauge measurements, which also show sea level along the coasts rising only about half as quickly as the satellite altimetry suggests.
But Willis Eschenbach here commented that he had downloaded the same file – but for the entire ocean – and found an average rise of 1.52 mm/year.
Which begs the question: How are scientists coming up with 3.2 mm/year?
Less than 1% of global tidal gauges agree with IPCC 2100 projection
US coastal sea-level rise “slowing down”
Moreover, a recent study of 53 long-term tide gauges scattered on the US east and west coasts found that sea-level rise has in fact slowed down.
In a nutshell: All the claims that we’re all going to drown seem to be flat out contradicted by data from along the coast.
