Coverage from increased rainfall causes micro climates
Towns which get no rain for years can be inundated with water and this erodes buildings. The reliefs are particularly vulnerable to rain and as sea temperatures rise the impacts of El Niño become more severe. Heavier rain has also resulted in a rise to the water table affecting foundation.
