Recently, the global average temperature has continuously set new records, and many parts of the world have experienced extreme high temperatures, severely impacting industrial and agricultural production, economic activities, and public health. Experts say that in the context of global warming, the superposition of moderate or above intensity El Ni ñ o events may lead to more frequent, wider, and stronger extreme weather events such as high temperatures, which will have a lasting and far-reaching impact on the economies of various countries around the world. Since the beginning of summer, Asia, Europe, North America and other regions have continued to experience high temperatures, with temperatures around the world, especially in the northern hemisphere, constantly breaking records. The preliminary research results released by the World Meteorological Organization show that early July this year was the hottest week on record on Earth. Extreme weather and related disasters caused by high temperatures have emerged in many parts of the world, causing varying degrees of life and property damage. Many countries in Europe have been hit by heatwaves. Small scale wildfires have occurred in Norway, Sweden, Denmark, Finland, and other regions. Forest fires have also occurred in some parts of France, and groundwater levels in many countries are below normal. The European Environment Agency said that under the influence of global climate change, extreme weather disasters such as heatwaves, floods and droughts occurred frequently or became the "New normal" of European summer. North America is also plagued by extreme weather. Recently, several states in the United States have experienced continuous high temperatures, affecting approximately 110 million Americans due to adverse weather conditions. The US emergency management department predicts that the heat wave may cause severe weather such as rainstorm, gale and tornado in the south. Canada, on the other hand, continues to be affected by wildfires, making this year the most severe year for wildfires in the 21st century. In Asia, large areas of India continue to suffer from extreme heat waves, with an increasing number of deaths due to the heat waves. Lahore, a city in the east of Pakistan, has seen record rainfall for 30 years, triggering large-scale floods. Bangladesh has suffered record breaking floods, affecting millions of people to varying degrees, while other regions have experienced droughts. Other regions of the world are also facing the threat of extreme weather. In Malawi, southeastern Africa, floods and mudslides caused by tropical cyclones have resulted in over 1000 deaths and 660000 displacement. Uruguay in South America is experiencing its worst drought in 44 years. Under the impact of extreme high temperatures and weather disasters, the economies of multiple countries have been impacted. For example, according to CBS, overheating weather causes $100 billion in annual losses to the US economy. Reuters quoted the climate Transparency report issued by environmental protection organizations as saying that by 2050, extreme high temperatures in India may eventually lead to a 15% decline in "outdoor work capacity", a reduction in the quality of life of up to 480 million people, and a loss of 2.8% of GDP. According to a recent study published in Science, the Washington Post reported that El Ni ñ o phenomenon may cause the Domino effect of extreme weather worldwide, trigger large-scale floods, droughts, wildfires, etc., cause crop deaths, tropical diseases and fish populations to plummet. This year's El Ni ñ o phenomenon may cause a loss of $3 trillion to the global economy in the next five years. Given that climate change may exacerbate the frequency and intensity of the El Ni ñ o phenomenon, even if countries fulfill their commitments to reduce carbon emissions
