Ummmm you'll note that it stopped completely in 1993-1997 and 1998-2000 and 2006-2009.

No, that's the La Nina signal. If you take the sea level rise curve, remove the seasonal cycle, remove the +3.1mm/yr trend, you are left with significant interannual variations. These variations correlate with the Multivariate ENSO Index.

The recent lower sea level values do not represent a change in the long-term trend of sea level rise. It's just the the large interannual variations we've observed over the whole length of the altimeter sea level record.

You may also note that rate of sea level rise over recent years has been less than the long-term average. This is believed to be due to the recent La Nina's we have been experiencing, though research on this is continuing. We will soon add a plot to the web site illustrating this effect.

Quoting from the above reference

The current temperature anomaly for March 2011 has just come in at -0.1C. That's MINUS 0.1C which is below the freezing point of water, so how can the arctic be melting?

Ijit! The Arctic ice sits on water. If the water is above freezing it will melt the ice. Water holds from 2000 to 4000 times as much heat as air for a given volume depending on its temperature so water will melt ice quicker than air.

The total temperature drop highlighted by the green line is almost as great as the entire warming that occurred since 1900! So much for global warming then! If this continues we will enter an ice age next year!

The drop shows the temperature drop from summer to winter and similar drops are shown elsewhere on the graph. We will have to see what the graph does when they publish the summer temperatures. Every one here knows we've had record cold this winter and record warmth this April. All that says is that we've had huge variations in climate which is what has been predicted with Climate Change.

Also, the graph he's published clearly shows a warming trend despite some major variations, probably inter seasonal, in temperatures. I didn't bother reading past the above quote. Even from my limited knowledge I can see that the bloke doesn't know what he's talking about.

Here's another graph from the same source



This clearly shows that the sudden drop at the end of the graph is last winter's reading and that anomaly is still +0.18 deg C. This graph also clearly shows a rising trend.

I wouldn't rely on that blog as a source of reliable information on anything. Either the bloke's an ijit or he thinks his audience is.

This is a post about the rate of rise of sea level and its use as a proxy.

clv101 in another post claimed:

Conclusions about the future can't be drawn from the 20th C. data set as both ice sheets were in balance until the mid 90s, today they are contributing 1.3mm/yr between them with unequivocal acceleration.

Clearly, the uneqivocal acceleration is equivocal!

I don't follow you? The 1.3mm from the ice sheets is based on their mass balance - it is unequivocal that they are losing mass at an accelerating rate. Don't confuse steric sea level rise with eustatic sea level rise.

Methinks the sea has already risen enough for the Inspector to find himself completely out of his depth. Arguing the topic with someone who does sea level for the day job is a bad move.

The point being that you can't claim that sea level rise is slowing down from a couple of years of data.

I should have realised that the ijit is 'merican. It's the stupid talking to the stupid.

Please send this to your senators and congressmen so they will have true information to base decisions on. Perhaps just as they are about to pass some Death Taxes they will see this graph and realize "hang on a second! we're being lied to!"

The last sentence is probably the only truth in the whole blog and the blogger is doing the lying.

I apologise. Having read a bit more, the bloke isn't an ijit, he's a comedian and it's a piss take. I didn't realise ,mericans had a sense of humour. Actually, they don't they have a sense of humor!

It's very well done. The comments are brilliant too.
