Yet another analysis exposes the huge discrepancy between satellite measured sea level rise in the middle of the ocean (3,2 mm/yr) and the rise measured along the coasts where people actually live (1.68 mm/yr).
Not shot 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.
But 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 rise along the coasts where it really matters for humans.
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).”
Thus the coastal trend is thus just half the total ocean trend!
Zoe’s findings agree nicely with tide gauges measurements, which also show sea level along the coasts rising only about half as quickly as the satellite altimetry suggests.
Also 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.
Less than 1% of global tide 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 are flat out contradicted by measurements made along the coast.
