Via The Guardian: El Niño: food shortages, floods, disease and droughts set to put millions at risk. Excerpt:
The UN has warned of months of extreme weather in many of the world’s most vulnerable countries with intense storms, droughts and floods triggered by one of the strongest El Niño weather events recorded in 50 years, which is expected to continue until spring 2016.
El Niño is a natural climatic phenomenon that sees equatorial waters in the eastern Pacific ocean warm every few years. This disrupts regular weather patterns such as monsoons and trade winds, and increases the risk of food shortages, floods, disease and forest fires.
This year, a strong El Niño has been building since March and its effects are already being seen in Ethiopia, Somalia, Kenya, Malawi, Indonesia and across Central America, according to the World Meteorological Organisation. The phenomenon is also being held responsible for uncontrolled fires in forests in Indonesia and in the Amazon rainforest.
The UN’s World Meteorological Organization warned in a report on Monday that the current strong El Niño is expected to strengthen further and peak around the end of the 2015. “Severe droughts and devastating flooding being experienced throughout the tropics and sub-tropical zones bear the hallmarks of this El Niño, which is the strongest in more than 15 years,” said WMO secretary-general Michel Jarraud.
Jarraud said the impact of the naturally occurring El Niño event was being exacerbated by global warming, which had already led to record temperatures this year. “This event is playing out in uncharted territory. Our planet has altered dramatically because of climate change,” he said. “So this El Niño event and human-induced climate change may interact and modify each other in ways which we have never before experienced. El Niño is turning up the heat even further.”
In 1997, the phenomenon led to severe droughts in the Sahel and the Indian subcontinent, followed by devastating floods and storms, which killed thousands of people and caused billions of dollars of damage across Asia, Latin America and and Africa.
The WMO said countries are expected to be much better prepared for a strong El Niño now than they were in 1997, but governments and charities are warning of serious food shortages and floods.
