A deadly mudslide that killed hundreds of people in Colombia earlier this month may portend the spread of more extreme weather conditions. Local weather forecasters have blamed the wet weather that has hit the region on the weather phenomenon known as El Niño.
First observed in the 19th century by Peruvian fishermen, the recurring weather phenomenon is known to affect Australasia as well South America. Its climatic effects can reach as far as West Africa triggering downpours or droughts. Previous episodes have had a significant impact on crop yields and the price of agricultural commodities as well as metal and energy prices.
