Atmospheric cooling theory

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. Greenland ice core published by Dansgaard et al. in 197 1

The results of oxygen isotope spectrum analysis show that the orbital period of the earth's climate is 654.38 million+years, of which 90,000 years is a cold period and 654.38 million+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]. But in the mid-1970s,

Since then, the temperature has not continued to decline, but has increased, which has promoted the development of artificial greenhouse effect research.

Kellogy's climate model in 1977 predicts that under the background of natural climate change, due to human pollution to the atmosphere, by 2050,

The global average temperature is higher than 4 degrees Celsius, and some people call it "super interglacial period" [3]. In the United States, the Department of Energy takes the lead.

And support some universities, national laboratories, industry and other system research institutions to carry out research on carbon dioxide. United States of America

The National Academy of Sciences organized two special groups to conduct research. They estimate that doubling carbon dioxide will make the average temperature of the earth at least.

1.5 degrees Celsius, but not more than 4.5 degrees Celsius. The United Nations Shanghai Communiqué and Geneva Communiqué of 200 1 further affirmed this change.

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 thought that artificial compounds

Freon destroyed the Antarctic ozone layer. Various international plans limit the emission of carbon dioxide and freon and transfer them to developed countries with advanced technology.

The export of new technologies and new products has brought rich economic benefits, added vitality to the new economy of the United States, and made the sustained growth of the American economy exceed.

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 global temperature changes and

Not entirely dependent on carbon dioxide content. In addition, historically, there are many factors that affect the content of carbon dioxide in the atmosphere, including human factors.

Vegetarianism also has natural factors. Whether the current changes are entirely caused by man-made greenhouse gases needs further study. About the greenhouse

The study of natural gas involves the adjustment of energy structure and the bearing capacity of developing countries caused by it, including scientific issues.

There are also 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 cause more intense

Natural greenhouse effect [5, 6]. Human activities can't change the laws of nature, only accelerate or decelerate. global climate

Cold and warm changes are mainly dominated by nature.

The natural cycle of climate change

Looking back on the data of the past 100 years, it shows that the Pacific Ocean experienced a warm "sardine period" to a cold "anchovy period" every 25 years.

Period "periodic changes. At present, it is in the stage of abundant anchovies around 1990. In the cold stage, the east

Strong ocean currents and the increase of nutrients in the Pacific Ocean have greatly increased the number of anchovies, salmon, groupers and seabirds. Western Pacific situation

On the contrary. At the same time, there are different patterns of air temperature, atmospheric circulation and carbon dioxide release. In the warm period, the eastern and western parts of the Pacific Ocean are two.

Some physical conditions 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 annual average change 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 changes lead to Antarctic continental sea ice.

The same trend changes. According to the statistical analysis results of observation data from 1973 to 1993, the Antarctic region is from 1973 to 1989,

The sea ice range has a decreasing trend of about 0. 16 latitude/10 year. From the late 1980s to the early 1990s, the Antarctic sea ice area has been gradually increasing.

The trend of increasing gradually, therefore, since 1973, the overall Antarctic sea ice still shows a weak decreasing trend [8].

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 a high altitude area.

Barometric flow, also known as 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. Second cycle

The "cold phase" appears in 1947 to 1976, and the "warm phase" appears in 1977 to 2000. If the "warm phase" of Ramadan

The encounter between "thunder" and "El Nino" will make it stronger and appear more frequently; If the "cold phase" of "La Madre" and

When the phenomenon of "La Nina" meets, then "La Nina" will show 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. Two Warming Periods in the 20th Century

(1925- 1944, 1978-2000) correspond to the "warm phase" of "la madre", but they all lag behind the eastern Pacific Ocean obviously.

Changes of sea surface temperature of sea ice in the Pacific Ocean 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. La madre phenomenon

Cyclic alternation repeatedly proves the existence of natural forces. It is worth learning that the cold phase of 1947- 1976 has made a lot of meteorology.

Economists exclaimed the arrival of the Little Ice Age. In 2000, "Ramad" entered a "cold period", once again reminding people that the momentum of global warming will gradually weaken.

Gradually weaken, and there will be cold and earthquake-prone periods in the next 30 years. Huge ocean earthquakes transfer deep-sea cold water to the surface and absorb carbon dioxide.

Weakening the greenhouse effect is an amplifier for climate cooling [10]. For the earth, which is increasingly short of energy and resources, this is what human beings are facing.

The biggest threat.

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, South China

The area of polar sea ice gradually increased [8], and the East Pacific entered the low temperature stage around the 1990s, with abundant anchovies. south

The turning point of the increase and decrease of polar sea ice is before the turning point of the sea surface temperature change in the eastern Pacific, and the turning point of the sea surface temperature change in the eastern Pacific is ahead.

La madre's cold and warm phase transition. This not only reflects the energy transfer process of solar activity change in quasi-60-year cycle, but also reflects the global climate change.

The first information and precursor of a cold. 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 human society in the global climate change cycle, Xu Jinghua proved that the global microclimate is the most suitable period for the development of human society.

Prosperity and global Little Ice Age led to agricultural production reduction, famine and ethnic migration [1 1]. According to Ren Zhenqiu's research, Jupiter, Saturn and heaven

Wang Xing and Neptune caused a fairly stable quasi-periodic change in the radius of the earth's revolution during the winter solstice, which was consistent with the global temperature change, especially in the northern hemisphere.

The vibration is consistent with the interval of 60 years. In the low temperature period at the beginning of this century and the relatively cold period in the sixties and seventies, at that time (190 1 and 1960), the earth.

The radius of revolution from the winter solstice to the sun is extended by 94 (equivalent to 0.6% of the distance between the sun and the earth) and 570 thousand kilometers respectively; 30-40 s and after 80 s.

During the warm period, the revolution radius of the earth during the winter solstice (1940 and 2000) was shortened by 760,000 km and 440,000 km respectively. Winter Solstice of the Earth from 2000 to 2020

When the revolution radius changed from minimum to maximum, he predicted that the global climate would enter a relatively cold period around 2020 [12].

Academician Wang pointed out that at the end of the "New Fairy Tree Incident" about 654.38 million years ago, the temperature over Greenland has increased in the past 50 years.

7oC, and this rapid change is repeated. Historical records show that global climate change is mainly controlled by nature, greenhouse gases.

Human emissions aggravate the process of global warming. In the period of severe climate fluctuation, human beings must make two preparations to prevent climate warming and cooling.

The cold weather began to show its advantages.

China Journal website news: From the afternoon of March 4th, 2004, the biggest snowstorm in March hit the Korean capital.

In the central region, including Seoul, the snow in some areas is as thick as 30 cm, which has paralyzed road traffic and forced schools to suspend classes. Since 2003,

Since June 165438+ 10, snowstorms have occurred all over the world. In 2003,165438+1October 7, the snowstorm in Tianjin was rare for 70 years; End of June 5438 +2004 10, Europe

Most areas were hit by blizzard [14].

Xinhua News Agency, Sofia, February 14 (Reporter Guo Shuang) The Balkan countries have been hit by a snowstorm recently, which has caused air, sea and peace in these countries.

Land traffic has been seriously affected. The ports in the port cities of Varna and burgas were forced to close due to the snowstorm on June 5438+03, and the capitals were guaranteed.

The Asian-African airport was also forced to cancel most flights due to strong winds. In Turkey, Bulgaria's southern neighbor, a snowstorm blocked Turkey.

Roads connecting 2,700 villages and towns paralyzed the country's railways and airports. Istanbul, Turkey's largest city, 80%

Electricity, running water and heating in this area were cut off by the snowstorm. Athens, the capital of Greece, was also hit by the worst snowstorm in recent 10 years.

The snow in the city is 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. Romani

Recently, the temperature in Asia has plummeted, and the temperature in the central Romanian city of curia Chuk, Meiere has reached MINUS 32 degrees Celsius.

Since the spring of 2000, there have been eight large-scale sandstorms in northern China. Compared with previous years, its frequency, participation degree

The scope greatly exceeds any year in history [16]. In 2004, sandstorms in China intensified. As of March 2004, 12,

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!
