Should n't sea levels be visible by now????

@ArishMell Don't be silly

@ArishMell We are seeing it islands are sinking, land is being flooded ,coastal erosion is getting worse , storm waves are getting larger how much more do you want to see its bad enough as it is .

@Rhode57 @Rhode57 you are delusional if you think that.

@wildbill83 good evidence

@wildbill83 very good

what the greenies call rising sea levels, people with common sense call erosion...

plate tectonics account for more movement than any claimed sea rise, the earths crust literally moves 2-4 inches per year...

@wildbill83 that makes sense

@wildbill83 cool photo, and very convincing for those who want to be convinced. For those who prefer truth to convenience:

Some key points:
"Plymouth Rock has not remained in its original location over the centuries, and sea level rise has been well-documented in the surrounding region, experts say. In addition, the photo also does not take account of regular tidal fluctuations."
"The rock has been broken, split, and relocated multiple times over the past two and a half centuries...The rock is regularly underwater at high tide in its present location underneath a granite portico built in 1921" Donna D. Curtin, executive director of the Pilgrim Hall Museum in Plymouth

@wildbill83 an article regarding Ft. Denison and a study conducted about the very real concern the government has about protecting this historical site:

https://www.climatechange.environment.nsw.gov.au/sites/default/files/2021-06/Fort%20Denison%20sea%20level%20rise%20study.pdf

" ...recent climate change induced sea level rise projections ranging between 20 and 100cm by the year 2100 will have a significant bearing on the management and utilisation of this iconic facility into the future and are examined in detail within the study...to address outstanding maintenance and repair issues on the Fort and to undertake research into key threatening processes, including the process of sea level rise."

(based on data, rather than ego based emotional reactions)

@Dust057 A rise of even half-way between those estimates (so 600mm - I surprised the writers used the centimetre) would have far more serious effects on huge numbers of people and buildings such as their homes, than on this one disused fort. Even just locally, the potential effects on the rest of Sydney and Sydney Harbour might be more to the point!

(Fort Denison, long disused as that, and its island now form a tourist attraction, and do hold tide-gauges.)
