Do sea levels actually precipitously rise and fall like climate alarmists say? Is there any actual evidence that surface temperature fluctuations lead to immediate sea level change?
Venice's foundations were first laid around 700 AD. And it's been exactly at sea level (for all practical purposes) ever since. Surely the Medieval Warm Period (950-1250 AD) would've flooded the city?? Or?

from what we know, the sea levels are much higher than any previous point in human history, and from direct observation, the amount of millimeters per year the sea level rises has been increasing year over year for decades now.

wrong chart

If it helps to interpret the data, most of the sea level rise is due to water temperature rising, and water expands when it is warm which accounts for more rise than ice melt. The water takes time to absorb heat, when you change the atmospheric temperature it will take a while for the ocean to "catch up", so most of the sea level rise we have locked ourselves into has not yet happened yet since the planet only started warming in the last few decades.

the rising sea levels have caused damage from floods to become more frequent in venice, so they're planning to erect flood barriers to deal with rising high tides of even the most pessimistic estimates.

Much of the east coast of the United States will be gone, along with Florida. These are some of the most heavily populated parts of the country. The economic losses will make the current national debt look like a penny on the street by comparison.

This type of sea level rise won't happen for centuries, before 2100 sea level rise is a much smaller issue compared to other effects.

Venice has always had floods. I'm referring to the fact that it's been *at sea level*.

Where and how was sea level measured at each point along the graph? I need exact sources for every measurement. Thanks.

>the planet is warming and not just densely packed asphalt-covered urban zones
proof?

Would ppm in the air vary depending on your proximity to emissions?

>>16722314 (OP)
the sea level was more than 120m lower about 20k years ago
so yes, sea levels dramatically change

>>16722433
dumbass

tide houses would measure the water level using tide gauges and log it.

>>16722493
depends on streams winds local construction and yes tide (wich is only a few cm the rest is a. swinging system). There wae eay too much influences and way to few measure points to get an global value. So it's modeled to scamdemica needs.

>>16722479
proof?

Do you not care to consider that we have evidence of sea levels being far lower and far higher OUTSIDE of human history? Sea levels varied massively without us even existing yet we jump on this bandwagon that every 'negative' change in the world is our fault? It's completely insane that all of this doom posting about sea level comes from an irrelevant increase of 15cm over 140 years. Really we just draw a fucking fit line out to 2100 and see a big number and predict the end of the world? What a joke. The climate has never been and will never be a constant so we shouldn't treat it like it is one. We need to adapt, not cry and demand we deindustrialize for tenuous claims of industry causing an ever changing climate to change.

Venice is also at sea level and on sinking land and has always had floods. Why are you ignoring all of this and attempting to use it as evidence of human caused sea level rise? Just because it sucks doesn't mean the fault lies with anyone other than the builders of Venice.
