Shortfacts about Ireland
Geography: A ring of coastal mountains surrounds low central plains. The highest peak is Carrauntoohil, which is 1,038 m. Ireland's least arable land lies in the south-western and western counties. These areas are largely mountainous and rocky, with dramatic green vistas, hence the attributive name "the Emerald Isle".
Climate: Overall, Ireland has a mild, but changeable, Oceanic climate with few extremes. The climate is typically insular, and as a result of the moderating moist winds which ordinarily prevail from the Atlantic, it is of a temperate nature, avoiding the extremes in temperature of many other global areas sharing similar latitudes.
