Doonbeg Golf Club on August 18, 2010 in Doonbeg, Co Clare, Republic of Ireland.

Authorities in Ireland have given President Donald Trump permission to build a seawall at his golf course on the west coast of the country.

Thirty-meter waves and driving rain have been eroding his coastal golf resort in Doonbeg, west Ireland.

Now The Trump International Golf Links Doonbeg, owned by the Trump Organization, has permission from the local council for two sea barriers of 630 meters and 260 meters in length.

Opponents have four weeks to appeal the decision, said Clare County Council in a statement.

The U.S. president has personally expressed doubts over the effects of climate change but the original application for the wall cited global warming and rising seas as a reason for needing the wall.
