The Terrors Of Climate Change

Climate Change has already had some adverse effects on the environment from extended drought seasons to increased temperatures in the oceans. In recent years, scientists have embarked on research to assess the effects of climate change on El Ni帽o. The phenomenon is associated with wild environmental conditions such as floods, droughts, and hurricanes and some research have suggested that such conditions will get intense in the context of climate change. El Ni帽o is Spanish word for 鈥渓ittle boy."

What Is The El Ni帽o Phenomenon?

The El Ni帽o climate system disrupts normal weather patterns and brings wild weather to various parts of the 海角社区. The event refers to the period when the Equatorial Pacific records unusually warm ocean temperatures. It occurs in a cycle called the El Ni帽o Southern Oscillation (ENSO) together with La Ni帽a, its opposite. The phenomenon is marked by the eastern Pacific having low air pressure while high air pressure is experienced in the western Pacific. The system occurs in a 2-7 year cycle. El Ni帽o is characterized by the weakening of trade winds in the western and eastern Pacific, the warming up of surface water temperatures on the South American coast, and an eastward shift of clouds and rainstorms.

Wild Weather Associated With El Ni帽o

El Ni帽o brings about changes in regular weather patterns across the 海角社区. The primary effects of the phenomenon are precipitation and temperature changes, variations in the intensity and track of storms, as well as the disruption of ocean currents. The system leads to some negative consequences such as reduced fish populations which frustrate fishing communities such as those in Ecuador and Peru. The fish species migrate north and south in pursuit of cold water. El Ni帽o causes drought spells in regions including Southern Africa, Australia, and Southeast Asia. Drought, in turn, causes fires, low agricultural production, and starvation. Other areas, such as the US and Chile experience increased rainfall which leads to floods and associated destruction. The changing climatic conditions can also facilitate the spread of plagues and diseases. The phenomenon has been blamed, in part, for the recent (2015-2016) Zika virus outbreak in South America. The warmer than usual conditions are conducive for the mosquitoes spreading the virus. Increased snake bites are also reported during an El Ni帽o. The consequences of El Ni帽o affect the economic, political, social, and health landscapes of many countries.

Super El Ni帽os

El Ni帽os are never similar, and no particular ocean and atmosphere patterns can be identified as the standard for the phenomenon. Three unusually intense El Ni帽os have notably gone down in history. The first one occurred between 1982 and 1983, and it was marked by the reversion of trade winds. This El Ni帽o was blamed for disasters ranging from droughts, storms, bushfires, to floods in almost every continent. The second super El Ni帽o happened from 1997 to 1998 and scientists have also called the 2015 to 2016 one as a super El Ni帽o.

Climate Change

The concept of climate change has become popular across the 海角社区 in recent years. The term means changes in normal climatic conditions. In the past, climate conditions such as rainfall, seasons, and temperatures, were predictable and informed activities including agriculture. This situation is no longer the case as climate is becoming more and more unpredictable. Climate change is used interchangeably with global warming to refer to the increasing surface temperatures on Earth. Human beings have been identified as the main contributors to this change. The burning of fossil fuels releases greenhouse gasses including carbon dioxide to the air which in turn trap heat in the atmosphere. Deforestation has also been identified as a major factor leading to global warming. Rising sea level, melting ice caps, intense heat waves, and an overall increase in global temperatures are some of the adverse effects of climate change.

Reasons Of A Potential Connection Between El Ni帽o And Climate Change

Scientists have identified distinct shifts in the behavior of El Ni帽os since the mid-1970s. First is the tendency for more frequent and intense El Ni帽os. The 1990-1995 El Ni帽o, for example, was the longest recorded one in the current century. The past 50 years have been identified as relatively having more frequent El Ni帽os. The two extreme El Ni帽os of 1982-1983 and 1997-1998 have also been singled out as notable events of the century.

The Connection Between El Ni帽o And Climate Change

El Ni帽o is naturally occurring, and scientists are divided on the effects of climate change on the phenomenon. The causes of El Ni帽o are yet to be clearly identified, and ocean temperatures are monitored to forecast the event. Climatologists have developed some models to determine the link between climate change and El Ni帽os, most of which have predicted a high likelihood of El Ni帽os turning into super El Ni帽os. A study undertaken in 2014 predicts that Super El Ni帽os may double in future in the context of climate change. The study was carried out by the use of 20 climatic models, and it concluded that super El Ni帽os might, instead of taking place every 20 years, may occur after ten years. The study鈥檚 findings have however attracted skepticism from some scientists. Although the event has been happening for thousands of years, it was only a few decades ago that observational evidence began to be recorded.

Thus, although scientists know there are lots of variations in El Ni帽os over a long stretched period of time, more data is needed to predict El Ni帽o changes. One aspect that scientists agree on is that the ocean has been absorbing increased heat since the industrial era began on Earth. As to how the ocean heat content will affect El Ni帽o, no study has been conclusive. Some climate models suggest that the ENSO cycle will weaken, while others say it will be more intense, and still others say there will be little effect. Another school of scientists has suggested that El Ni帽o will definitely be modified since it is operating on unchartered territory, i.e., that of climate change. Whereas the phenomenon is naturally occurring, climate change is human induced, and these two events have the potential to interact in ways never seen before.
