Línte na Farraige – Imagining Future Sea Levels in Dublin

Clara Clark from Cycling Without Age has sent us this report on the recent launch of the Línte na Farraige installation in Blackrock, County Dublin. This launch follows an equivalent launch at the Spanish Arch in Galway in December 2022. 

Línte na Farraige is a series of LED light installations across Irish coastal sites that represent the impact of future sea level rise and storm surges. This installation at the Martello Tower in Blackrock Park Co. Dublin was launched on 21st February 2023. 

This postcard image is the calculated sea level in the year 2100, at normal (not surge) height. Surges and easterly winds will drive wave heights to multiples of this height. 

Speakers at the launch included DLR Cathaoirleach Mary Hanafin, Minister Catherine Martin, Minister for Tourism, Culture, Arts, Gaeltacht, Sport and Media and Deputy Leader of the Green Party, DLR Council CEO Frank Curran, and Finnish Ambassador to Ireland Ms Raili Lahnalampi. Ms. Lahnalampi is a keen and regular cyclist, who arrived on her bike!

This installation was designed by a Finnish design group. Attendees included a team from CARO, the The Dublin Metropolitan Climate Action Regional Office (CARO) which supports and coordinates climate action undertaken by the four Local Authorities of South Dublin, Fingal, Dun Laoghaire‐Rathdown, Dublin City Council (DCC). DCC is the lead authority in the region. Dublin CARO is based in the Civic Offices. 

This CARO project is headed by David Dodd. The scientists are from Maynooth University and emeritus Professor of Geography John Sweeney attended. Their work is guided by the work of the IPCC, the Intergovernmental Panel on Climate Change (see https://www.ipcc.ch/). 

These art / science installations are designed to create awareness of the impending sea level rise from now on. By 2050 the level will be up by 0.4m on today’s level. Solar-powered, the LED light lights up at dusk. The cycle path and walkway through Blackrock Park is busy all day and evening, as commuters pass by the tower. This should imprint on people the impact of climate change and our need to do something about it. 

More details are on this signboard beside the tower:

If you want to imagine just how significant the sea level rise will be for this small child in his lifetime, this picture tells its own story (the DART line is in the background).
