East Cork, Waterford, Galway and the Shannon Estuary will be the first to bear the brunt of an “alarming and startling” rise in sea levels, a TD has warned.

As the Irish Examiner reports, David Stanton (Cork East) expressed his fears of a “truly frightening” outcome for many coastal communities in the continued absence of a national coastal risk strategy.

“There is no point waiting until the seawater is up to our knees and then saying we should have planned for this 20 years ago,” he said.

Discovery of the remains of a “drowned” prehistoric house in north Connemara may be further evidence of sea-level rise along the Atlantic coast in the last millennium.

As The Sunday Times reports today, parts of a small prehistoric dwelling covered by sea except at low spring tide have been identified by archaeologist Michael Gibbons and engineer Shane Joyce on the coast south-west of Clifden, Co Galway.

The site is in a sheltered “lagoon-like setting” on the tip of the Faul peninsula, at the junction of Clifden and Ardbear bays.

Gibbons said that the structure is similar in size to early Neolithic houses, and it is protected from tidal surges by Oileán Gearr or Islandagar, a small island on its western side.

Gibbons said it was further evidence of a “drowned prehistoric landscape”, which has been researched and dated by NUI Galway palaeoecologists Prof Michael O’Connell and Dr Karen Molloy.

O’Connell and Molloy have estimated that sea levels rose by as much as four metres on the Atlantic coast in later prehistory - as in 1,000 years ago – with Galway Bay being younger than originally estimated.

Prof O’Connell said that it was “quite reasonable” to suggest the structure identified by Gibbons and Joyce may be early Neolithic, given that sea level rise occurred in the late Neolithic period.

O’Connell and Molloy’s work focused on tree stumps, believed to be bog pine, which have been exposed at low tide by storms dating back to 2010, along with pollen analysis of coastal peat deposits.

Gibbons said that a shell midden dating from 4,000 BC on the Errislannan peninsula, just south-west of the Faul location, was also evidence of Neolithic settlement by early farmers.

Dublin Bay’s sea level seems to be rising faster than forecast — and at twice the global average over the past two decades.

The Irish Times reports on this startling claim from Dun Laoghaire-Rathdown County Council’s (DLRCoCo) climate change action plan, which also notes that weather extremes are “likely to increase in their frequency and intensity”.

The report comes following one of Ireland’s hottest summers on record, itself just months after a first ever Status Red warning for snow was issued by Met Éireann.

Three Dublin local authorities launched their climate action plans on Monday (9 September), with DLRCoCo’s plan pledging to “prioritise nature-based flood defences where possible” over the next five years.

Ferry & Car Ferry News The ferry industry on the Irish Sea, is just like any other sector of the shipping industry, in that it is made up of a myriad of ship operators, owners, managers, charterers all contributing to providing a network of routes carried out by a variety of ships designed for different albeit similar purposes.

All this ferry activity involves conventional ferry tonnage, 'ro-pax', where the vessel's primary design is to carry more freight capacity rather than passengers. This is in some cases though, is in complete variance to the fast ferry craft where they carry many more passengers and charging a premium.

In reporting the ferry scene, we examine the constantly changing trends of this sector, as rival ferry operators are competing in an intensive environment, battling out for market share following the fallout of the economic crisis. All this has consequences some immediately felt, while at times, the effects can be drawn out over time, leading to the expense of others, through reduced competition or takeover or even face complete removal from the marketplace, as witnessed in recent years.

Arising from these challenging times, there are of course winners and losers, as exemplified in the trend to run high-speed ferry craft only during the peak-season summer months and on shorter distance routes. In addition, where fastcraft had once dominated the ferry scene, during the heady days from the mid-90's onwards, they have been replaced by recent newcomers in the form of the 'fast ferry' and with increased levels of luxury, yet seeming to form as a cost-effective alternative.

Irish Sea Ferry Routes

Irrespective of the type of vessel deployed on Irish Sea routes (between 2-9 hours), it is the ferry companies that keep the wheels of industry moving as freight vehicles literally (roll-on and roll-off) ships coupled with motoring tourists and the humble 'foot' passenger transported 363 days a year.

As such the exclusive freight-only operators provide important trading routes between Ireland and the UK, where the freight haulage customer is 'king' to generating year-round revenue to the ferry operator. However, custom built tonnage entering service in recent years has exceeded the level of capacity of the Irish Sea in certain quarters of the freight market.

A prime example of the necessity for trade in which we consumers often expect daily, though arguably question how it reached our shores, is the delivery of just in time perishable products to fill our supermarket shelves.

A visual manifestation of this is the arrival every morning and evening into our main ports, where a combination of ferries, ro-pax vessels and fast-craft all descend at the same time. In essence this a marine version to our road-based rush hour traffic going in and out along the commuter belts.

Across the Celtic Sea, the ferry scene coverage is also about those overnight direct ferry routes from Ireland connecting the north-western French ports in Brittany and Normandy.

Due to the seasonality of these routes to Europe, the ferry scene may be in the majority running between February to November, however by no means does this lessen operator competition.

Noting there have been plans over the years to run a direct Irish –Iberian ferry service, which would open up existing and develop new freight markets. Should a direct service open, it would bring new opportunities also for holidaymakers, where Spain is the most visited country in the EU visited by Irish holidaymakers ... heading for the sun!
