What is the most abnormal weather?

At the beginning of the new year, abnormal weather appeared all over the world, highlighting the grim trend of global warming. Scientists predict that 2007 is likely to exceed 65,438+0,998 due to the El Ni? o phenomenon and the greenhouse effect, making it the hottest year on record.

Recently, the warm winter weather broke the world record. In Heilongjiang Province, which has always been extremely cold, the average temperature in early June of 5438+1reached the highest temperature in winter since June of 5438+095 1. However, it was not until June+10/October 10 in 65438 that the first snowfall occurred in new york since winter, which was the latest snowfall since June 1878.

Abnormal weather has brought many serious effects. Russian health official 65438+1October 17 said that due to the increase of rodent food in warm winter, a large number of people in western Russia were infected with rodent-borne diseases. However, the World Cup Men's Skiing Championships scheduled to be held in France in 65438+ year1October 20th and 265438+ year1October 20th were cancelled due to "high temperature" and heavy rain. Due to the bad snow conditions, a series of world-class skiing events were postponed or cancelled.

Scientists have analyzed that there are two main reasons for this warm winter weather, one is the influence of a new round of El Ni? o phenomenon, and the other is the greenhouse effect formed by the long-term accumulation of greenhouse gases.

Therefore, the Global Risk 2007 report released by the World Economic Forum and other institutions in Geneva on June 5438+1October 10 lists climate change as one of the most severe challenges facing the world in the 2 1 century. According to the report, natural disasters caused by global warming may lead to large-scale population migration, energy shortage and economic and political turmoil in some areas in the next few years.

From this perspective, the problem of global warming has reached an extremely serious juncture.
