From the BBC:
The Trump International hotel and golf links at Doonbeg on the west coast of County Clare was acquired in 2014.
Storms that year caused significant erosion of sand dunes at the course and the Trump organisation submitted plans to Clare County Council to build a two-mile (2.8km) limestone wall to limit the impact of the seas.
At 4m in height and 20m wide, the 200,000-tonne structure would have required some 200,000 tonnes of rock for construction.
The €10m wall would protect against the wasting impacts of the seas, the original application said.
The documents went on to detail that "the rising sea levels and increased storm frequency and wave energy associated with global warming can increase the rate of erosion".
Climate change is real, as long it is affecting Trump’s property! Oh the irony! Oh, the hypocrisy!
