The question of "Why Seven Meters" is a really good one. And there is a good answer for this. But the answer requires some preliminary work. Sea level changes every century as climate conditions change. After an ice age, sea level will rise as the glaciers shrink. As another ice age grows, sea level will fall as water is captured on the continents. Between ice ages, continents rise as well when released from the weight of thousands of feet of ice. Without human intervention, we would likely see the trend of slow sea level rise continue as it has for centuries.

Speaking of Science: UW scientists offer sea level rise projections, investigate icy uncertainty
Come the year 2100, Washington State’s coastline could be in for some noticeable changes. Coastal cities from Bellingham to Olympia are already planning for the possibility of rising waters over the next 50-100 years.

World sea levels to rise 1.5m by 2100--scientists
As the climate models start to incorporate dynamic ice characteristics a better picture of the extent of projected sea level rise in the middle term (before 2100) is emerging. This time frame would mean that people born today will potentially live long enough to experience the impacts.
The BBC (February 24, 2008) reports on a scientific expedition to the West Antarctic Ice Shelf: Antarctic glaciers surge to ocean
Excerpt below:
"Throughout the 1990s, according to satellite measurements, the glacier was accelerating by around 1% a year. Julian Scott's sensational finding this season is that it now seems to have accelerated by 7% in a single season, sending more and more ice into the ocean.

New data from the NASA GRACE mission satellite shows that ice melt at the edges of the Antarctic is accelerating, and outpacing the build-up of snow in the interior.

"WASHINGTON (AP) -- An already relentless melting of the Arctic greatly accelerated this summer, a warning sign that some scientists worry could mean global warming has passed an ominous tipping point. One even speculated that summer sea ice would be gone in five years.
