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 Baths Renovation

Afloat has been reporting on the new plans for the publically owned Dun Laoghaire Baths site located at the back of the East Pier since 2011 when plans for its development first went on display by Dun Laoghaire Rathdown County Council. 

Foreshore consent was applied for in 2013.

Last used 30 years ago as the 'Rainbow Rapids' before falling into dereliction – the new site does not include a public pool.

The refurbished Dun Laoghaire Baths include the existing Baths Pavilion for use as artist workspaces, a gallery café and for the provision of public toilet facilities. 

Work finally got underway at Dún Laoghaire on the €9 million redevelopments of the old Dún Laoghaire Baths site in June 2018 under a contract with SIAC-Mantovani.

The works have removed dilapidated structures to the rear of the Pavilion to permit the creation of a new route and landscaping that will connect the walkway at Newtownsmith to both the East Pier and the Peoples Park. 

Original saltwater pools have been filled in and new enhanced facilities for swimming and greater access to the water’s edge by means of a short jetty have also been provided.

The works included the delivery of rock armour to protect the new buildings from storm damage especially during easterly gales. 

It hasn't all been plain sailing during the construction phase with plastic fibres used in construction washing into the sea in November 2018

Work continues on the project in Spring 2020 with the new pier structure clearly visible from the shoreline.

A plinth at the end of the pier will be used to mount a statue of Roger Casement, a former Sandycove resident and Irish nationalist.
