We keeop hearing that "sea levels are rising".

Can anyone point me to a proper scientific study or set of facts which shows that sea levels have actually risen and if so, by how much and over how long a stretch of time.

Graphs fairly linear.... about 40mm/decade? something like that?

Rising for sure, but not to the apocalyptic extent we keep being told.

Coastal erosion is a fact. Sea level rise is a probability. The impacts of sea level rise on coastal erosion is likely to make the current situation worse.

A lot of the media reporting is of a worst case which is extensively modelled to try and analyse potential risk to property. It us likely to be not as bad as this. However it is important to get that data to make an informed decision about future developments on the coastline and more importantly in estuary areas.

I had been led to believe that the earth is still coming out of the last mini ice-age, and this is the reason that sea levels are rising. Have I heard wrong?

Or you could ask Al Gore. He has an affinity for beach-front property...

'fraid so.

The website www.skepticalscience.com has a long list of common 'arguments' and this is number 47. I like the concluding bit 'This argument is akin to saying that when you drop a ball off a cliff, it falls because it used to be higher. There is a physical mechanism for these changes.'. Don't take my word for it; visit the site, read the article and the papers in cites to support it, and come to your own conclusion.

No, you heard right.



As the graphic shows, any recent sea level rise is very minor in the wider scheme of things and has been tailing off to near zero for some while, choosing the last few decades and a scale that magnifies the small change exaggerates its appearance.

The very recent fall in global sea level is continuing.

Also, in certain parts of the world - IIRC the south cost of England is one such example - geological changes, tectonic plates and other such stuff that I have not a clue about (I'm not making this up - no mention of Muslamic Ray Guns here) mean the ground levels are also dropping.

That's written on the City Limits board of Atlantis.

So, between 25,000 and 10,000 years ago it rose dramatically but in more recent times,(the last few thousands of years) it has continued to rise but at a much lower rate.

How do they distingusih between coastlines which are sinking, due to crustal movement, and actual waters rising.

Is the volume of liquid water in the oceans greater now than at any point since 25,000 years ago?

You know, I love history, especially Ancient history – I love reading about how man and civilisation have progressed, and at times, made the occasional step in the wrong direction with disastrous consequences – all the warning signs are there before the disaster happens, but they happen anyway. I also know that geological history is part of our history – it has to be.

I say this because I genuinely feel that, for the past decade or so, we have had to endure an age of ‘anti-enlightenment’, where we are expected to suspend disbelief, rip up everything we have learnt before and swallow what the new age ‘scientists’ preach (and preach is the correct word in this context) Everything before year zero is supposed to be forgotten about, and the new doctrines embraced - -anyone who disagrees are non-believers who have no interest in man’s future apart from their own.

‘Real’ periods of ‘real’ enlightenment throughout our history have brought about positive change, along with an increase in population, general well-being and advances in technology. I truly believe that the new faith want to take us into civilisation’s third Dark Age, using the same tactics that have been implemented since the dawn of time. I always hope that we, as a civilisation are too canny to allow this to happen – but I’m not so sure anymore. I find it scary how useless our ‘betters’ are and how gullible we still seem to be.

Ask the powers thta be what the sea level rise in Scotland are like?

oh wait a minute, the sea level is dropping scotland, but rising in Dorset

COuld it possible be that the UK is recovering from the last ice age. THe uk is like a big see saw at the moment- the weight of ice pusched SCotland under water and pushed up southern england. Now the ice has gone, the oppposite is happening.

Presumably you were listening to Radio 4 this morning?

Almost as good as the single woman with three kids who only lives on £67/week. Obviously no housing allowance, child allowance, council tax payments, free laptops, free food etc etc . just £67/week.

Of course if you have a bread winner in the family then this ins't such a huge problem.

+1 and it's nice to hear someone echo my own feelings on the matter.

(I will keep my ill-informed opinions about the exodus of fat, mobility-scotter-bound pensioners to coastal retirement being the cause of land elevation changes to myself.)
