From Climate Change Indicators: Sea Level
Quote:
After a period of approximately 2,000 years of little change (not shown here), global average sea level rose throughout the 20th century, and the rate of change has accelerated in recent years.
If not discussing climate change, then why did you cite an article about climate change and how it affects oceans?

A sudden change in climate created by mankind also explains a sudden change in ocean levels. For 2000 years; no change. Suddenly mankind is massively burning fossil fuels. Climate change started. And oceans began rising.

Climate was stable for 2000 years. Ocean levels were stable for 2000 years. Suddenly both changed drastically when mankind started changing climate. Somehow that ia a normal event because such changes once took many thousands of years? Conclusion by ignoring numbers is disingenuous.

Naysaying is not a productive answer. Ignoring relevant facts from your citation further demonstrates denial of well proven science. Where are facts that dispute well proven science. Naysaying does not prove anything.

Climate and ocean level changes happened over tens and hundred of thousands of years. That proves so much change in only 100 years is normal? Show me those numbers.

If the sea is compressing the floor down from the weight of the water above it, does that mean that the seas can hold more water and cancel the volume increase from glacier ice melting?

If the scientist comes to this conclusion they will surely be shifted from scientific research to managing a Cinnabon somewhere in Nebraska.

Killing the narrative isn't good for a scientific career.

Ocean level was 400 FEET lower 16,000 years ago! That's a rate of change of 30 inches increase per century.

It's true that the rate has increased in recent years. That's odd because it came during the hiatus in warming. A lot of sea level rise is due to thermal expansion. I wonder if that's one reason why AR5 says it can't attribute recent high sea levels to AGW.

Do you believe in AR5, tw, or are you a science denier?

What is AR5? Never saw (remember) that abbreviation in science articles.

AR5 is the Fifth Assessment Report of the Intergovernmental Panel on Climate Change.

I read that the land once covered with ice, which is an awful lot of it, is slowly rebounding from the compression. Wouldn't that mess with the ancient sea level calculations?

Read an interesting article today about why some islands are disappearing and why sea level rise isn't the main problem, or reason to panic yet.

tw, AR5 is the IPCC Fifth Assessment Report. The IPCC is the Intergovernmental Panel on Climate Change-- "an intergovernmental body of the United Nations, dedicated to providing the world with an objective, scientific view of climate change, its natural, political and economic impacts and risks, and possible response options." And concluding that:
Quote:
*Warming of the atmosphere and ocean system is unequivocal. Many of the associated impacts such as sea level change (among other metrics) have occurred since 1950 at rates unprecedented in the historical record.
*There is a clear human influence on the climate
*It is extremely likely that human influence has been the dominant cause of observed warming since 1950, with the level of confidence having increased since the fourth report.
I'm not a climate scientist, so I'll take their word for it.
