Get the high score of global climate cooling information!

Just when the evidence of global warming was overwhelming, the information of global cooling came quietly. Looking at the essence through superficial phenomena, the dynamic mechanism of global climate change has undergone major changes, which indicates that a cooling process similar to that in the 1950s and 1970s is coming.

Historical lessons: from lamenting the Little Ice Age to misinterpreting the greenhouse effect.

People may still remember the climate "cooling theory" that appeared in the early 1970s. 197 1 year The results of oxygen isotope spectrum analysis of Greenland ice core published by Dansgaard et al. show that the earth's climate has an orbital period of 1 10,000 years, of which 90,000 years is a cold period and 1 10,000 years is a warm period. According to this law, the warm period of the current climate is coming to an end, and the theory of climate "cooling" once became the mainstream [1, 2]. However, since the mid-1970s, the temperature has not continued to decrease, but has increased, which is helpful for the development of artificial greenhouse effect research.

Kellogy's 1977 climate model predicts that under the background of natural climate change, due to human pollution to the atmosphere, the global average temperature will rise by 4 degrees Celsius by 2050, which is called "super interglacial period" [3]. In the United States, the Department of Energy takes the lead in guiding and supporting some universities, national laboratories, industrial and other system research institutions to carry out research on carbon dioxide. The National Academy of Sciences organized two special groups to conduct research. They estimate that doubling carbon dioxide will increase the average temperature of the earth by at least 65438 0.5 degrees Celsius, but not more than 4.5 degrees Celsius. The United Nations Shanghai Communiqué and 200 1 Geneva Communiqué further affirmed this trend.

The Antarctic ozone hole, which is as famous as the greenhouse effect, once triggered a global ozone hole panic. At that time, most scientists believed that the artificial compound Freon destroyed the Antarctic ozone layer. Various international schemes to limit the emission of carbon dioxide and freon have brought rich economic benefits to developed countries with advanced technology. The export of new technologies and new products has added vitality to the new economy of the United States, which has made the American economy grow continuously for more than 8 years. Backward developing countries are facing enormous economic pressure.

Academician Zhou pointed out that the climate on the earth has fluctuated greatly recently, but the carbon dioxide content has been rising, which shows that the global temperature change does not depend entirely on the carbon dioxide content. In addition, historically, there are many factors that affect the content of carbon dioxide in the atmosphere, including human factors and natural factors. Whether the current changes are entirely caused by man-made greenhouse gases needs further study. The study of greenhouse gases involves the adjustment of energy structure and the affordability of developing countries, including scientific, economic and political issues. We shouldn't jump to conclusions easily until it is scientifically clear [4].

Recent observations show that the destruction of ozone by solar wind is much greater than that by Freon. The release of methane hydrate from the seabed will lead to a stronger natural greenhouse effect [5, 6]. Human activities can't change the laws of nature, only accelerate or decelerate. The change of global climate is mainly controlled by nature.

The natural cycle of climate change

Looking back on the data of the past 100 years, it is shown that the Pacific Ocean undergoes a periodic change from a warm "sardine period" to a cold "anchovy period" every 25 years. At present, it is in the stage of abundant anchovies around 1990. In the cold stage, the strong ocean currents and the increase of nutrients in the East Pacific greatly increased the number of anchovies, salmon, groupers and seabirds. The situation in the western Pacific is just the opposite. At the same time, there are different patterns of air temperature, atmospheric circulation and carbon dioxide release. In the warm period, the physical conditions in the east and west of the Pacific Ocean are just the opposite, which makes sardines multiply in the Pacific Ocean [7].

Antarctic sea ice has almost exactly the same change. In the past 30 years, all areas south of 50 degrees south latitude have been warming. The average annual variation trend of1957 ~199310 is 0.20 degrees Celsius, and the warming range is 0.3~0.6 degrees Celsius higher than the global average every hundred years. Among them, in the Antarctic Peninsula in recent 30 years, especially in recent 10 years, the temperature rise is the most significant. Temperature change leads to the same trend change of Antarctic continental sea ice. According to the statistical analysis results of the observation data of 1973 ~ 1993, the Antarctic sea ice area has a decreasing trend of about 0. 16 latitude/10 years from19, and since the 1980s,

Similar to the periodic change of temperature in the Pacific Ocean, the air flow over the Pacific Ocean also has an approximate periodic change. "la madre" is an upper air pressure flow, also known as the Pacific Decadal Oscillation (PDO). In the past 100 years, "la madre" experienced two complete cycles. The "cold phase" of the first cycle occurs from 1890 to 1924, while the "warm phase" occurs from 1925 to 1946. The "cold phase" of the second cycle appeared in 1947 ~ 1976, and the "warm phase" appeared in 1977 ~ 2000. If the "la madre" of "warm phase" meets "El Nino", it will be stronger and appear more frequently; If "la madre" and "La Nina" in the "cold phase" meet, then "La Nina" will show a strong momentum and appear frequently [9]. In the climate records of the 20th century, there are two periods of global warming: 1925 to 1944, 1978 to 2000. The two warming periods in the 20th century (1925- 1944, 1978-2000) correspond to the "warm phase" of la madre, but both lag behind the changes of sea ice temperature in the East Pacific and Antarctica.

Signal of global cooling and its danger warning

The fact that the global temperature has risen rapidly in the past 30 years is obvious, but human power cannot change the laws of nature. The cyclical alternation of Lamard phenomenon has repeatedly proved the existence of natural forces. It is worth learning that the cold phase of 1947- 1976 made many meteorologists exclaim the arrival of the Little Ice Age. "la madre" entered a "cold period" in 2000, reminding people once again that the momentum of global warming will gradually weaken, and there will be cold and earthquake-prone periods in the next 30 years. Ocean earthquake transfers deep-sea cold water to the surface, absorbs carbon dioxide and weakens the greenhouse effect, which is an amplifier of climate cooling [10]. For the earth, which is increasingly short of energy and resources, this is the biggest threat facing mankind.

There is no evidence that the earth came out of the Quaternary Great Ice Age. However, there is evidence that from the late 1980s to the early 1990s, the Antarctic sea ice area showed a gradual increase trend [8], and the East Pacific entered a low temperature stage around the 1990s, with a large number of anchovies appearing. The turning point of Antarctic sea ice change precedes the turning point of East Pacific SST change, and the turning point of East Pacific SST change precedes the cold-warm phase change of la madre. This not only reflects the energy transfer process of solar activity change in quasi-60-year cycle, but also is the initial information and precursor of global climate cooling. Global warming will soon be a thing of the past, and mankind will be retaliated by the sudden cooling of nature.

According to the history of the development of human society in the global climate change cycle, Xu Jinghua proved that the global microclimate is the most suitable period for the prosperity and development of human society, and the global Little Ice Age led to agricultural production reduction, famine and ethnic migration [1 1]. According to Ren Zhenqiu's research, during the winter solstice, Jupiter, Saturn, Uranus and Neptune make the revolution radius of the earth change quite stably in a quasi-periodic way, which is consistent with the 60-year interval vibration of global temperature change, especially in the northern hemisphere. During the low temperature period in the early 20th century and the relatively cold period in the 1960s and 1970s, the revolution radius of the earth was extended by 94 (equivalent to 0.6% of the distance between the sun and the earth) and 570,000 kilometers (190 1 and 1960) respectively. During the warm periods from 1930s to 1940s and after 1980s, the radius of the earth's revolution was shortened by 760,000 km and 440,000 km respectively during the winter solstice (1940 and 2000). During the winter solstice from 2000 to 2020, the radius of the earth's revolution changed from the minimum to the maximum, and he predicted that the global climate would enter a relatively cold period around 2020 [12]. Han Yanben analyzed the global and northern and southern hemisphere temperature anomaly data published by NASA since the middle of19th century, and obtained the preliminary results that they had quasi-periodic fluctuations for about 60 years. This period is one of the main periodic components of their mid-term fluctuation, which can play an important role in modulating the overall change trend of temperature. The analysis shows that the period component is time-varying. In the19th century, the period length was slightly over 60 years, and then slowly shortened, and the months in the late 20th century were between 55 and 60 years. The so-called intensification of the greenhouse effect caused by human activities does not seem to disturb its weight this week [13].

Academician Wang pointed out that at the end of the "New Fairy Tree Event" about 654.38 billion years ago, the air temperature in Greenland rose by 7 degrees Celsius in the past 50 years, and such rapid changes occurred repeatedly. Historical records show that global climate change is mainly controlled by nature, and greenhouse gas emissions aggravate the global warming process. Therefore, in the period of severe climate fluctuation, human beings must make two preparations to prevent climate warming and cooling [14].

The cold weather began to show its advantages.

News from the website of China Journal: From the afternoon of March 4th, 2004, the biggest snowstorm in March, which has never happened in a century, hit the central region including Seoul, the capital of South Korea. In some areas, the snow was as thick as 30 cm, which caused road traffic paralysis and forced schools to suspend classes. Since June 2003 165438+ 10, snowstorms have occurred all over the world. In 2003,165438+1October 7, the snowstorm in Tianjin was rare for 70 years; At the end of June 5438+ 10, 2004, most parts of Europe were hit by blizzard [15].

Xinhua News Agency, Sofia, February 14 (Reporter Guo Shuang) The Balkan countries were recently hit by a snowstorm, which seriously affected the land, sea and air traffic. The ports of Varna and burgas, Bulgaria's seaports, were forced to close on June 5438+03 due to snowstorm, and Sofia Airport, Bulgaria's capital, was forced to cancel most flights due to strong wind. In Turkey, Bulgaria's southern neighbor, snowstorms blocked the roads leading to towns in 2,700 villages in Turkey, paralyzing the country's railways and airports. 80% of electricity, running water and heating in Istanbul, Turkey's largest city, were interrupted by snowstorms. Athens, the capital of Greece, was also hit by the worst snowstorm in 10 years, and the accumulated snow in the city was as deep as 50 cm. Meteorologists say that the temperature in Athens and Thessaloniki, the second largest city in Greece, has dropped to freezing point. The temperature in Romania has plummeted recently, and the temperature in Chuk, curia, Meiere, a city in central Romania, reached MINUS 32 degrees Celsius [16].

Since the spring of 2000, there have been eight large-scale sandstorms in northern China. Compared with previous years, the frequency and scope of sandstorms have greatly exceeded any year in history [17]. In 2004, sandstorms in China intensified. As of March 2, 2004, there have been six sandstorms.

In 2000, "La Madre" entered the "cold period" to remind people once again: be alert to the rapid global cooling!
