How does this really work? NASA's website says we can bounce radar off the ocean from a satellite and this shows that the sea level has been rising a couple millimeters per year. But google says the average wave height in the middle of the ocean is anywhere from 1 to 10 meters. Wouldn't the margin of error be like 5000 times the observation? And waves aren't seasonally periodic so how could you even keep measuring the same cycle of a wave at the same part of the ocean? Something doesn't add up
Sea level isn't rising, it sinking. Tropical islands in the Pacific are growing, there isn't anywhere on the planet that sea levels have swamped the land, sea level is dropping dramatically in higher latitudes too. There is no evidence of sea level rising anywhere.

>>16823259>https://science.nasa.gov/kids/earth/how-do-we-measure-sea-level/This is the NASA website I already looked at. It doesn't talk about what assumptions are used to resolve amplitude of the waves. The other website you linked doesn't either.>>16823248Even if that's true how would you know? The global level not level around some island.
>>16823279The key word is average. Try to think what happens to the waves when you measure the same spot dozens of times over months and then dozens of months over years. Also the beams aren't accurate enough to focus on a single wave anyhow, it's all about averages.
Nobody knows exactly what will happen in 10 years and if they claim otherwise I would be skeptical.
I have to pay higher home owners insurance rates because scientists keep on lying about "the world is coming to an end because of cow farts"
