Sea rise greatest in 6,000 years

Guardian - The rise in sea levels seen over the past century is unmatched by any period in the past 6,000 years, according to a lengthy analysis of historical sea level trends.

The reconstruction of 35,000 years of sea level fluctuations finds that there is no evidence that levels changed by more than 20cm in a relatively steady period that lasted between 6,000 years ago and about 150 years ago.

This makes the past century extremely unusual in the historical record, with about a 20cm rise in global sea levels since the start of the 20th century. Scientists have identified rising temperatures, which have caused polar ice to melt and thermal expansion of the sea, as a primary cause of the sea level increase.

Not true.

1000 years ago the vikings were sailing
south of Greenland in ice free waters.

Their camps and defense systems were
at 2-3 meter higher grounds from the
sea water due to much warmer climate.

Making sense of senseless sea level scares in Norfolk Virginia – 60% of the rise is from subsidence, the remainder from landfill settling
