I didn't find anything about uneven sea level rise there. The only thing they didn't take into account was the mass displacement of 50 million climate refugees in their boats raising sea level oh dam that didn't happen either.

Sea level rise is not anything to worry about for a lonnnnnnnnnng lonnnnnnnnng time. When, and if......it accelerates to become a problem, mankind will deal with it. Until that time, it is only arm waving.

Well Sig, you said it a long time ago but it would appear that sea levels are now actually going down "The two-year-long decline is continuing at a rate of 5mm per year
“The latest sea level numbers are out,” says Steven Goddard on Real-Science.com. “Envisat* shows that the two year long decline is continuing, at a rate of 5mm per year.”
“No doubt Al Gore will pass this good news on to all his viewers,” laughs Goddard"Sea Level Continues Inexorable DeclineSo how long before we are told that the drop in sea level was forecast predicted projected by the models and it is an expected effect of Global Warming Climate Change and we need to have more regulation of fossil fuels and higher taxes?

sealevel.colorado.edu/Why does the graph shown in above link suggest that sea levels are still rising? Is there a better source link? Just curious.

sealevel.colorado.edu/Why does the graph shown in above link suggest that sea levels are still rising? Is there a better source link? Just curious. Doug: The 1st graph is not a very good graph. It ignores Envirstat or whatever the European satellite is called. Look down further, you will see that GMSL has not risen for years. And in fact, if using data from last year the trend would be down. However, 5 years does not establish a long term trend. One thing that the flat short term trend shows is that the oceans are not building up heat, as some believers, (can't call them scientists), would have you think. It is well known physics that there is a thermal expansion to water, yes.....even sea salted water. Being glaciers etc are still calfing, the short term trend actually indicates cooling oceans. And lo and behold, this is verified by ARGO data.

After all, isn't Greenland losing Ice Mass at an unprecedented rate?
(Of course, those saying that think we are all stupid. The actual mass loss is within error bars of measurement.)

An example is.....Greenland loses 2 gigaton of ice this year, last year it lost 1 gigaton of ice. So, a 50% increase.....(yes, I know how to use percentages, most folks don't)..... But the total ice mass of Greenland is millions of gigatons. So by virtue of analogy, the beach lost 2 grains of sand this year verses one grain of sand last year.

HOW BIG A RISE?

Sig, it seems the more we learn we continue to find the oceans play a major part in the climatic system. As the AMO transitions to a cold regime it will be an interesting watch...

The sad thing is that so few even contemplate how the cold regime will upset the world.

MEMO TO IPCC: More to Air than N2, O2, and CO2 In the next couple of days, South Americans could get a taste of Africa without even stepping on a plane. That's because powerful winds over the continent are lifting up thousands of tons of dust from the Sahara Desert, and moving it 5,000-or-so miles over the Atlantic Ocean toward northern Brazil, Venezuela, Colombia and other places around the Caribbean Sea.
The plume of particulate matter goes by the tough-to-say-quickly name of the "Saharan Air Layer."
According to University of Wisconsin-Madison Reseachers:
Scientists have discovered a correlation between hurricane activity in the Atlantic and thick clouds of dust that periodically rise from the Sahara Desert and blow off Africa’s northwest coast. They found that during periods of intense hurricane activity, dust was relatively scarce in the atmosphere, while in years when stronger dust storms rose up, fewer hurricanes swept across the Atlantic....
The researchers say that this makes sense, because dry, dust-ridden layers of air probably help to “dampen” brewing hurricanes, which need heat and moisture to fuel them. That effect, Velden adds, could also mean that dust storms have the potential to shift a hurricane’s direction further to the west, which means it would have a higher chance of hitting the United States and Caribbean islands.
This stuff is comprised predominantly of fine silica sand and clay dust, which tends to attract attact H2O molecules, which results in atmospheric humidity that cannot condense large enough to create rainfall, according to NOAA.
As an aerosol, The Sahara Air Layer has a range of effects on the radiation spectrum that are poorly understood and modeled, even by the IPCC AR-4 account in Chapter 8 of that document. Considering that this dirt isn't CO2, poor understanding would not be surprising in any IPCC document. The phenomena doesn't occur all the time, but its intermittant and swirling appearance in the Inter-tropical Convergence Zone (ITCZ) confounds measurement of emissivity and subsequent modeling.
If the Saharan Air Layer can have the effect of dampening hurricane formation, then it can also have some effect on ocean warming or cooling.

The Sahara dust is a very important source of phosphorous in the Amazon basin. Not many people know that.
