What is the El Nino phenomenon? Will this year be the hottest year in history?

"El Nino phenomenon", also known as El Nino phenomenon, mainly refers to a situation that "the temperature of tropical ocean water in the eastern and central Pacific Ocean continues to warm abnormally, changing the global climate pattern, causing drought in some areas and excessive rainfall in some areas".

Recently, the US Climate Prediction Center announced: "The possibility of El Ni? o (Pacific Warm Period) in August this year is over 90%. The National Oceanic and Atmospheric Administration (NOAA) estimates that 2023 has a 50% chance of becoming the hottest year on record. "

In addition, according to the report of Global Climate released by WMO, "20 16 became the warmest year on record because of the' double critical strike' caused by a very powerful El Ni? o event and the climate warming caused by human activities.

This shows that this year is expected to become the hottest year in history. In addition, looking at the temperature data in recent 60 years, the hottest year at present is 1966 Anhui drought. In the drought, the temperature in Huoshan, Anhui Province reached 43.3 degrees Celsius, making it the highest temperature on record. (Of course, some people will say that the hottest year is eight years of Qianlong, which is 1743. It is said that the temperature in that year was as high as 45 degrees Celsius, but after all, the history is too long, and there is no accurate evidence to prove it, so I won't say it. )

So what effect will El Nino have? In my opinion, it is mainly the following two aspects:

On the one hand, extreme weather conditions such as drought and flood will occur frequently, resulting in reduced grain production. According to past experience, in the El Ni? o year, "there may be dry weather in Southeast Asia, Australia, South Asia subcontinent and other regions, while the rainfall from the equatorial region in the central Pacific Ocean to the west coast of South America continent may increase, which means that floods may occur in Latin America (especially Brazil and Argentina)." Not long ago, the relevant authoritative agricultural personnel in the Philippines said that El Ni? o would affect the country's rice supply.

On the other hand, it will endanger people's health. Excessive temperature can lead to heatstroke, nausea and fatigue. At the same time, the intensification of solar radiation may also cause dizziness, skin burns, retinitis, and even cataracts and other symptoms or diseases. I remember 20 16 (El Nino year), when I was still in college and went out to work part-time on weekends. Because of the hot weather, I didn't do a good job in heatstroke prevention, so I got heatstroke.

Whether this year will become the hottest year in history is still inconclusive, but in any case, according to the current situation, it will definitely be hot, so I would like to remind everyone that we must do a good job in heatstroke prevention and cooling when going out. In addition, although the weather changes beyond our own ability, we must protect the environment from ourselves and contribute our own strength.
