Summary of your research with embedded links to evidence from your blog posts that supports your thesis.

EL Niño is a very complex topic, but also a very interesting one too, as stated by Encyclopedia Britannica El Niño in oceanography and climatology, the anomalous appearance, every few years, of unusually warm ocean conditions along the tropical west coast of South America. This event is associated with adverse effects on fishing, agriculture, and local weather from Ecuador to Chile and with far-field climatic anomalies in the equatorial Pacific and occasionally in Asia and North America as well.”, and “The intensity of El Niño episodes varies from weak thermal anomalies (2–3 °C [about 4–5 °F]) with only moderate local effects to very strong anomalies (8–10 °C [14–18 °F]) associated with worldwide climatic perturbations.” Also El Universo states some effects of  EL Niño  “Late last month (December), one of the worst rains and floods in decades killed more than 150,000 evacuated in Paraguay, Argentina, Brazil and Uruguay, following the rising rivers.”, “The increased flow of the Paraguay River and caused 130 thousand evacuees four people were killed by falling trees.”,  “ The effects of El Niño are one of the most virulent since 1950, he predicted the World Meteorological Organization (WMO) of the United Nations. (I)”, “ Texas was recovering from unusual tornados in December, after days of storms in a vast region from the southwestern United States to Canada that left at least 43 dead.”, “Texas was recovering from unusual tornados in December, after days of storms in a vast region from the southwestern United States to Canada that left at least 43 dead.”, “On December 28, the National Weather Service said 21 states from New Mexico in the south to Michigan, were under observation by the storms. (I)”.

So if in the next 2 to 7 years weather similar to this happens then you know that it is an El Niño year.
