I think those Global Warming nuts are a few millenia late. It seems to me that they would have had more to work with back when the last glaciers began retreating - sometime around 20, 000 years ago.

An island made by global warming

Sea level rise is already accelerating. Sea levels are going up around the world by about 3.1mm per year - the average for the period 1993-2003. That is itself sharply up from an average of 1.8mm per year over the longer period 1961-2003. Greenland ice now accounts for about 0.5 millimetre of the total. (Much of the rest of the rise is coming from the expansion of the world's sea water as it warms.)
WTF?!?!? What is that in paranthesis?
MUCH OF THE REST OF THE RISE IS COMING FROM THE EXPANSION OF THE WORLD'S SEA WATER AS IT WARMS.
And what's that at the beginning of the paragraph?
SEA LEVELS ARE GOING UP 3.1MM PER YEAR.
Let's look at what is happening.
We have a sun. We have a moon. The sun heats up the air and surface of the planet. The moon pulls our water towards it as our earth and the moon cha-cha together around the sun.
We agree so far, right?
In light of recent news that Mars is experiencing it's own global warming episode (!), it stands to reason that the same sun that shines so brightly on Mars, also shines brightly on Earth.
Now, let's review some simple math laws.
Equality
The equals sign in an equation is like a scale: both sides, left and right, must be the same in order for the scale to stay in balance and the equation to be true.
The addition property of equality says that if a = b, then a + c = b + c: if you add the same number to (or subtract the same number from) both sides of an equation, the equation continues to be true.
The multiplication property of equality says that if a = b, then a * c = b * c: if you multiply (or divide) by the same number on both sides of an equation, the equation continues to be true.
The reflexive property of equality just says that a = a: anything is congruent to itself: the equals sign is like a mirror, and the image it "reflects" is the same as the original.
The symmetric property of equality says that if a = b, then b = a.
The transitive property of equality says that if a = b and b = c, then a = c.
Why am I boring you with math? Because it's important to remember that there are certain laws that supersede our emotions on this subject.
What I'm trying to say here is that if the sun shines brighter here, it is shining brighter on Mars, and vice versa.
Given that, can you agree with me that more sun shine equals more warm ocean water? Again, we agree on something.
Water covers 75% of the earth's surface, so it stands to reason that some of that is catching a few more rays. Now, do you know about the properties of seawater?
The viscosity (i.e., internal resistance to flow) of seawater, for example, is higher than that of fresh water because of its higher salinity. The density of seawater also is higher. Seawater's freezing point is lower than that of pure water and its boiling point is higher.

There are two things going on here.
One, seawater is denser than fresh - which means to me that deep seawater is has more salinity than the surface of the ocean. And if the upper levels are closer in chemical composition to fresh water, chances are that the properties of this layer would be correspondingly closer to fresh.
Which means, two, the surface of the ocean will act more like fresh water and respond to solar heating.
Go back up that opening quote.
Much of the rest of the rise is coming from the expansion of the world's sea water as it warms.
Rising temps - rising water, and all from our shining sun!
Rising temps? Remember, that same sun is shining over land too, heating it up as well as the air over it.
More tomorrow....and I'll firm up this line of thinking...
