Ireland is not a particularly cold country, mainly due to the Gulf Stream. Places further south than Ireland, such as parts of Canada and the USA get worse winter weather than Ireland does. You will get ice at times, but not very much and it is' not a permanent feature, like in countries closer to the north or south poles. Ireland can get bad winters, as it did in the winters of 2009/2010 and 2010/2011. Some winters are not bad, like the winter of 2011/2012 has been. So Ireland would not be regarded as being an icy country.
