Detailed explanation-1: -So, the correct answer is ‘Temperature rise leads to odd climatic changes’.
Detailed explanation-2: -El Niño causes the Pacific jet stream to move south and spread further east. During winter, this leads to wetter conditions than usual in the Southern U.S. and warmer and drier conditions in the North. El Niño also has a strong effect on marine life off the Pacific coast.
Detailed explanation-3: -For example, in the Southern United States, during the fall through spring, El Niño usually causes increased rainfall and sometimes destructive flooding. La Niña, however, usually causes drier weather in the South, but the Northwest tends to be colder and wetter than average.
Detailed explanation-4: -El Niño impacts weather systems around the globe, triggering predictable disruptions in temperature, rainfall and winds. La Niña is the opposite – a cooling phase of ENSO that tends to have global climate impacts opposite to those of El Niño.
Detailed explanation-5: -El-Nino is a warm ocean current that sometimes appears off the coast of Peru in South America during the month of December. It increases the surface temperature of the sea and affects the movement of monsoon winds in the Indian Ocean and causes a drought-like situation in the Indian sub-continent.
