Coastal News: Connemara 'Disappearing', Landfill Erodes Into Irish Sea, Plastic Pollutes Oceans

#CoastalNotes - Is Connemara at risk of disappearing into the sea? According to one geologist, that's a distinct possibility.

As the Irish Mirror reports, Jonathon Wilkins noticed that the tide was flooding channels in a peat bog near NUI Galway – a tell-tale sign of 'post-glacial rebound'.

That's the process of the land recovering from the weight of glaciers during the Ice Age, and in most cases it means the level of the earth is rising, such as northern parts of the island of Ireland.

But Connemara is one of those that's dropping, and slowing slipping below sea level as the seawater effectively dissolves the bogs and granite bedrock.

Wales-based geological expert Wilkins described what he saw as "very powerful evidence that sea level, to my surprise, is rising in this area, and demonstrably over quite a short time scale."

Disappearing even faster into the sea is an old landfill site in Bray – and it's raised the ire of environmentalists.

According to the Belfast Telegraph, the disused rubbish tip north of the Co Wicklow seaside town continues to lose some of its 200,000 tonnes of refuse into the Irish Sea due to coastal erosion.

And that's despite the problem being identified more than 20 years ago, according to Coastwatch – which says some 200 metres of the face of the landfill site has been exposed by weathering, littering the cliffs below.

The pollution only adds to the 8.8 millions tonnes of plastic that's dumped into the world's oceans every year, according to the journal Science.

The Irish Times reports on these latest findings, which show that one third of this plastic waste is produced by China alone.
