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.

The Half Ton Class was created by the Offshore Racing Council for boats within the racing band not exceeding 22'-0". The ORC decided that the rule should "....permit the development of seaworthy offshore racing yachts...The Council will endeavour to protect the majority of the existing IOR fleet from rapid obsolescence caused by ....developments which produce increased performance without corresponding changes in ratings..."

When first introduced the IOR rule was perfectly adequate for rating boats in existence at that time. However yacht designers naturally examined the rule to seize upon any advantage they could find, the most noticeable of which has been a reduction in displacement and a return to fractional rigs.

After 1993, when the IOR Mk.III rule reached it termination due to lack of people building new boats, the rule was replaced by the CHS (Channel) Handicap system which in turn developed into the IRC system now used.

The IRC handicap system operates by a secret formula which tries to develop boats which are 'Cruising type' of relatively heavy boats with good internal accommodation. It tends to penalise boats with excessive stability or excessive sail area.

Competitions

The most significant events for the Half Ton Class has been the annual Half Ton Cup which was sailed under the IOR rules until 1993. More recently this has been replaced with the Half Ton Classics Cup. The venue of the event moved from continent to continent with over-representation on French or British ports. In later years the event is held biennially. Initially, it was proposed to hold events in Ireland, Britain and France by rotation. However, it was the Belgians who took the ball and ran with it. The Class is now managed from Belgium.
