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 2024 Vendée Globe Race

A record-sized fleet of 44 skippers are aiming for the tenth edition of the Vendée Globe: the 24,296 nautical miles solo non-stop round-the-world race from Les Sables d’Olonne in France, on Sunday, November 10 2024 and will be expected back in mid-January 2025.

Vendée Globe Race FAQs

Six women (Alexia Barrier, Clarisse Cremer, Isabelle Joschke, Sam Davies, Miranda Merron, Pip Hare).

Nine nations (France, Germany, Japan, Finland, Spain, Switzerland, Australia, and Great Britain)

After much speculation following Galway man Enda O’Coineen’s 2016 race debut for Ireland, there were as many as four campaigns proposed at one point, but unfortunately, none have reached the start line.

The Vendée Globe is a sailing race round the world, solo, non-stop and without assistance. It takes place every four years and it is regarded as the Everest of sailing. The event followed in the wake of the Golden Globe which had initiated the first circumnavigation of this type via the three capes (Good Hope, Leeuwin and Horn) in 1968.

The record to beat is Armel Le Cléac’h 74 days 3h 35 minutes 46s set in 2017. Some pundits are saying the boats could beat a sub-60 day time.

The number of theoretical miles to cover is 24,296 miles (45,000 km).

The IMOCA 60 ("Open 60"), is a development class monohull sailing yacht run by the International Monohull Open Class Association (IMOCA). The class pinnacle events are single or two-person ocean races, such as the Route du Rhum and the Vendée Globe.

Zero past winners are competing but two podiums 2017: Alex Thomson second, Jérémie Beyou third. It is also the fifth participation for Jean Le Cam and Alex Thomson, fourth for Arnaud Boissières and Jérémie Beyou.

The youngest on this ninth edition of the race is Alan Roura, 27 years old.

The oldest on this ninth edition is Jean Le Cam, 61 years old.

Over half the fleet are debutantes, totalling 18 first-timers.

The start procedure begins 8 minutes before the gun fires with the warning signal. At 4 minutes before, for the preparatory signal, the skipper must be alone on board, follow the countdown and take the line at the start signal at 13:02hrs local time. If an IMOCA crosses the line too early, it incurs a penalty of 5 hours which they will have to complete on the course before the latitude 38 ° 40 N (just north of Lisbon latitude). For safety reasons, there is no opportunity to turn back and recross the line. A competitor who has not crossed the starting line 60 minutes after the signal will be considered as not starting. They will have to wait until a time indicated by the race committee to start again. No departure will be given after November 18, 2020, at 1:02 p.m when the line closes.

The first boat could be home in sixty days. Expect the leaders from January 7th 2021 but to beat the 2017 race record they need to finish by January 19 2021.

Today, building a brand new IMOCA generally costs between 4.2 and €4.7million, without the sails but second-hand boats that are in short supply can be got for around €1m.
