Is West Vancouver really bracing? Is this where you live ? Were is this in relation to Vancouver?


From this link by NOAA - this for Vancouver Canada-
https://tidesandcurrents.noaa.gov/sl...tml?id=822-071

"The relative sea level trend is 0.53 millimeters/year with a 95% confidence
interval of +/- 0.21 mm/yr based on monthly mean sea level data from
1909 to 2018 which is equivalent to a change of 0.17 feet in 100 years."

Where do you think the melt water from retreating glaciers to going?

A small fraction went into the three gorges dam in china. Raising 39 trillion kilograms of water 175 meters above sea level which changed the location of the pole by 2 cm, and slows the rotation speed of the earth decreasing the time in a day by 2.68 microseconds.

Does anyone know how the length of a day or the location of the pole has changed from melting glaciers? How much will it change if greenland melts completely? Some rough estimates claim 2 milliseconds. Others claim 0.43 seconds.

Back on the glacier where do you think the hundreds of billion tons of new ice each year come from ? Greenland has been gaining for near a decade now do the math .

Greenland to Three Gorges. Amazing. Just wow.

You really need to relearn the water cycle

The location I dont recall but the main time I recall being banded about was 3.45ms

I’m so sick of this “sky is falling” BS. 30 years ago we were predicted to be destroyed, drowned, devastated & done by 2010. The goal post keep moving, the fear keeps growing, and the BS gets piled higher and deeper.
After this last fiasco of Covid - being the 2nd coming of the Black Death - I’m done. My entire family got Covid after have been backed twice. My brother and his family got it after having no vac at all. For all of us it was just a prolonged version f the seasonal flu.
I do t trust anything the government tells me anymore. I don’t trust anything the press tells me anymore. I just listen to what my own common sense tells me from my own observations.
BTW. If someone like Obama really believed in Global warming and rising sea levels ( and had access to all the best and latest intelligence) would he build houses on the beach front coast of Martha’s Vinyard ? And no so hear of a beach front house in California as well ?
I’m done with all the fear mongering.

It's the same problem as the whole climate change "debate", really. "Alarmists" have been telling us that complete disaster is 5 years away for decades. I'd bet that every 5 years or so the number of people who believe this declines. Eventually we will reach the point of no return. But I wouldn't be surprised if no one believes it.

Greenland is losing ice extensively along its margins, where fast flowing ice streams are pushing more ice into the ocean, than is gained in the center of the ice sheet.

According to Cap Allon, at one of newhaul’s favourite CONSPIRACY- PSEUDOSCIENCE [fake] news and [wacko] opinion website, “Electroverse”:
“Data from the Danish Meteorological Institute (DMI) shows that Greenland ice melt slowed significantly during the past decade, and that the trend has now swung to one of growth.”
In fact: It does not.


But, satellite observations confirm Greenland continues to lose ice. There has been no reversal in the trend, according to experts.

The institute's Greenland ice sheet mass change data [2] shows substantial losses around the margins of the ice sheet, since 2002. It also shows small increases in mass, at high elevation areas, near the center of the ice sheet, due to increased precipitation in those areas.

However, even with these gains, the Greenland ice sheet has lost [5?] trillions of metric tons of ice.
The glacial growth is not keeping up with glacial loss.

Accounting for both surface melting and discharge of icebergs, the Greenland ice sheet lost around 166 billion tonnes of ice, over the 12-month period ending in August.
This means that 2021 is the 25th year in a row where Greenland has lost more ice than it gained.

While the ice sheet's decline has been well-documented, over the past two decades, this study [3], led by Michalea King, of the Byrd Polar and Climate Research Center, found that widespread glacier retreat helped push the ice sheet from a balanced, to an imbalanced state. This work suggests that even if the oceans and atmosphere were to stop warming today, the ice sheet will continue to lose more ice than it will gain.

“Managed Retreat”

The City of Grand Forks, British Columbia, has spent $16.5 million in a flood mitigation program, buying approximately 90 properties [1] most at risk of damage, as extreme weather events become more common. A combination of river water and sewage swamped the suburb of Ruckle, in Grand Forks, B.C. in 2018. Now, the city is demolishing dozens of homes, in the area, to mitigate future impacts from extreme weather events.
The program is an example of managed retreat, which refers to the co-ordinated movement of people, and sometimes infrastructure, away from natural hazards, often brought about by extreme weather events.
Grand Forks plans to demolish most homes in the neighbourhood, by the end of April 2022, allowing much of the area to return to natural floodplain and wetland. The city says it will also build a dyke, to protect homes in the surrounding area.

In Canada, different levels of government have spent hundreds of millions of dollars, on managed retreat buyout programs; including Calgary [2], and High River, Alberta, where residents were devastated by flooding, in 2013.

But the decision to abandon, rather than protect, homes can be controversial, as the City of Surrey learned, when it proposed looking into moving or abandoning 400 homes, in the Crescent Beach community, in order to avoid the effects of sea level rise, over the next century [3]. Public backlash, and vocal opposition, soon had the city back away from managed retreat.
Crescent Beach, along with 20 per cent of Surrey's land area, lies on a coastal floodplain, and is just a few metres above sea level, which is expected to rise one metre by 2100, and two metres by 2200.

I will start to worry about sea level rise when Barack Obama and Al Gore sell their ocean front mansions......until then, not so much.
