Those graphs were done when the new software model was using the IPCC outlook for "3ft. of sea level rise (SLR) by the year 2100."
Today, I want to use that same group to show how the SLR looks under the "20-year-doubling" projection.
That is half of what Dr. James Hansen used when he mentioned the issue in a recent paper:
One of the nation's most recognizable names in climate science, Dr. James Hansen, released a new paper this week warning that even 2 degrees(Former Top NASA Scientist Predicts Catastrophic Rise In Sea Levels). You can read more about the various degrees of "doubling" here.
The paper, which will be published online in the European Geosciences Union journal Atmospheric Chemistry and Physics Discussion later this week, projects sea levels rising as much as 10 feet in the next 50 years.
What I like best about this configuration is that, as planned, it is a continuous flow of history with the future projection taking that into consideration.
Previous models only did the future without consideration of the past in terms of
I put a red dot at the intersection where history ends and the future begins, and I changed the sea level from millimeters to meters.
Which is better than all of them being ground up into the sausage of "global allie samie average" IMO.
We saw how different sea level change (SLC) can be when we took a look at the West
Proof of Concept - 3).
I will do a post on that group again now that the model is doing "doubling" projections, and is closer than the IPCC model to the reality of future SLC on the east coast.
Not only that, the impact that SLF will have on sea ports has been discussed and it is shockingly significant (Peak Sea Level - 2).
That 1m / 3ft. SLC comes around when only 1.14% of the Earth's ice sheets melt (Why Sea Level Rise May Be The Greatest Threat To Civilization - 3).
In The Year 2525" sung by way too many establishment scientists takes our attention away from the looming crisis.
Anyway, if anyone comments to say "these graphs look very much alike Dredd" I will answer "that is because their history is similar."
But to be able to include all the historical years along with the future years, which include a "doubling" acceleration increase, those changes were necessary.
Another factor is that the tide gauge stations began keeping records at different times in the past, and since SLC has been changing since the industrial revolution began to change the chemistry of the atmosphere, oceans, and land, that is to be expected.
You can notice that they tend to be different in the sense of beginning at different sea levels when they begin their record keeping in different years and locations (see how the red dot moves about too).
Note that the historical data is exactly the same, only the future projection data is different.
The future data is different because the switch from the conservative IPCC 2100 model data to the 20-year-doubling model data is a significant change.
