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.

Dun Laoghaire to Dingle Yacht Race Information

The biennial Dun Laoghaire to Dingle race is a 320-miles race down to the east coast of Ireland, across the south coast and into Dingle harbour in County Kerry.

The race is organised by the National Yacht Club.

It never fails to offer a full range of weather, wind and tide to the intrepid entrants, ranging from a 32ft cruiser to a 79ft all-out racer.

Three divisions are available to enter: cruiser (boats equipped with furlers), racing (the bulk of the fleet) and also two-handed.

D2D Course change overruled

In 2019, the organisers considered changing the course to allow boats to select routes close to shore by removing the requirement to go outside Islands and Lighthouses en route, but following input from regular participants, the National Yacht Club decided to stick with the tried and tested course route in order to be fair to large and smaller boats and to keep race records intact.

RORC Points Calendar

The 2019 race was the first edition to form part of the Royal Ocean Racing Club “RORC” calendar for the season. This is in addition to the race continuing as part of the ISORA programme. 

D2D Course record time

Mick Cotter’s 78ft Whisper established the 1 day and 48 minutes course record for the Dun Laoghaire to Dingle Race in 2009 and that time stood until 2019 when Cotter returned to beat his own record but only just, the Dun Laoghaire helmsman crossing the line in Kerry to shave just 20 seconds off his 2009 time.
