Earth's greenhouse gases
Greenhouse gases (ghgs) refer to gaseous components that exist naturally in the atmosphere and are produced by human activities that can absorb and emit radiation from the earth's surface, atmosphere, and clouds. Common greenhouse gases include water vapor, carbon dioxide (CO2), and methane (CH). However, because the concentration of water vapor is not directly affected by human activities and is not the main driver of climate change, the so-called greenhouse gases mainly refer to carbon dioxide, methane, nitrogen dioxide (N O), fluorides (HF), perfluorides (PVP), sulfur hexafluoride (CHF), and so on. In 1896, the Swedish physicist Svante Arsenius first studied the relationship between greenhouse gases and temperature. Since then, people's research on greenhouse gases has gradually begun. The main greenhouse gases in the atmosphere are carbon dioxide, methane, and nitrogen dioxide, which contribute 25%, 15%, and 4%, respectively, to the greenhouse effect. Since the industrial revolution in the 19th century, with the acceleration of the process of industrialization, human activities have greatly increased the concentration of greenhouse gases such as methane and carbon dioxide in the atmosphere. For example, the global atmospheric carbon dioxide concentration observed by the World Meteorology Organization's Global Atmospheric Observation Program reached 417.9 + 0.2 parts per million in 2022. The release of greenhouse gases would lead to extreme weather, global sea level rise, ocean fermentation, accelerated iceberg melting, and other problems, which would have a great impact on human life and production. In order to reduce greenhouse gas pollution, countries around the world have taken a series of measures, such as establishing a sound accounting and monitoring system, formulating greenhouse gas pollution regulations, and optimization of energy structure. On December 10, 1997, the third Conference of the States parties to the United Nations framework convention on climate change adopted the Paris Agreement of the United Nations framework convention on climate change. The outline formally stipulated the reduction of carbon dioxide, methane, nitrogen dioxide, fluorides, fluorides, and sulfur hexa.

How the greenhouse earth will affect the earth survey report
The greenhouse effect would have a serious impact on the earth in many ways. In terms of the ecological environment, it would lead to a decrease in biological species. As the Earth's temperature rose, the ecosystem changed. Many species found it difficult to adapt to the new environment, so they went extinct or migrated. In terms of climate, changes in atmospheric circulation and ocean currents caused extreme weather events such as droughts, floods, storms, heat waves, etc., which caused huge losses and difficulties to human production and life. The sea level would continue to rise. Due to the melting of glaciers and the expansion of seawater, the sea level had risen by 20 centimeters in the past century and could rise by more than 60 centimeters by the end of the century. This posed a great threat to coastal cities and island countries. Agricultural production had also been severely affected. Soil drought, increased pests and diseases, and shortened crop growth periods affected agricultural production and food security. Agriculture in developing countries was more sensitive and vulnerable to these factors. Human health was also affected. The heat island effect intensified, air pollution worsened, and the spread of infectious diseases expanded. This increased the incidence and mortality of cardiovascular diseases, respiratory diseases, skin cancer, and other diseases. The spread of diseases such as Dengue fever and malaria might expand, and the incidence of diseases such as asthma and chronic obstruction lung disease continued to rise. The stratosphere of the Earth's atmosphere became thinner and thinner due to the influence of greenhouse gases. The universe sucked away the Earth's atmosphere (about 100,000 tons) every year. If the Earth lost its atmosphere, all living things would go extinct within three minutes.
The circulation of ocean currents on the greenhouse earth
In the greenhouse Earth state, the ocean current cycle had its own unique characteristics. ** 1. Formation mechanism ** 1. ** Driven by the wind ** - The wind belts in the atmospheric circulation (such as the trade wind belt, the westerly wind belt, etc.) interacted with the surface of the ocean to drive the flow of seawater to form surface currents. For example, the northeast and southeast trade winds near the equator pushed the seawater westward, forming the North and South Equator Warm Current. Under the continuous effect of the wind, a global ocean circulation system was formed. 2. ** The difference in temperature and salinities ** - The temperature and saltiness of the seawater affected its density, causing the seawater to flow. When he was in the greenhouse, the global rainfall and evaporating were inconsistent, resulting in differences in ocean salinities in different regions. The density difference caused by salinities became the main formation mechanism of deep water. In the high latitudes, the temperature of the sea water was lower, the salinities were higher, and the density was higher; in the low latitudes, the temperature of the sea water was higher, the salinities were lower, and the density was lower. This difference in density caused the sea water to form a circulation in the vertical direction. The cold and heavy sea water sank, and the warm and light sea water rose. The sinking sea water flowed from the bottom of the ocean to the low latitudes, and the rising sea water flowed from the surface to the high latitudes, forming a cycle of deep ocean currents and surface ocean currents. 3. ** The influence of the Earth's rotation ** - The earth's rotation produces a gravitational force that has an important impact on the direction and path of ocean currents. The objects moving in the northern hemisphere were deflected to the right, and the objects moving in the southern hemisphere were deflected to the left, causing the ocean currents in the northern hemisphere to show a clockwise circulation, while the ocean currents in the southern hemisphere showed a counterclockwise circulation. ** 2. Main Ocean Current System ** 1. ** Equator Ocean Current System ** - It was composed of the North Equator Warm Current, the South Equator Warm Current, and the Equator Countercurrent. Driven by the trade winds, the North and South Equator Warm Current flowed westward along the north and south of the equator respectively. When the two met near the equator, they formed an equator current that flowed from west to east due to the accumulation and compensation of seawater. The system was of great significance in terms of heat transport, climate, and ecological environment in the surrounding areas. For example, the tropical rainforest climate in the equator was affected by the tropical warm current, and the warm and humid climate provided a good environment for biological species. 2. ** Drifting in the west wind ** - It was located in the middle and high latitudes of the southern hemisphere. It was a powerful ocean current formed by the prevalent westerly wind. Due to the lack of land in the middle and high latitudes of the southern hemisphere, the west wind could flow around the earth. The water temperature was low, which had a cooling effect on the surrounding climate. For example, the Patagonia Plateau in southern South America was affected by the cold and dry climate, forming large deserts and grasslands. 3. ** Gulfstream and Kuroshio (important ocean currents in the mid-latitudes of the northern hemisphere)** - The Gulf Stream was a powerful warm current in the North Atlantic Ocean. It originated in the Gulf of Mexico and flowed northward along the east coast of the United States. It then transported a large amount of heat and water vapor across the Atlantic Ocean to western Europe. (Although the data did not mention the special situation of the Blacktide under the greenhouse earth, it can be speculated that it has a corresponding role and function in the overall ocean circulation system.) In addition, during the late cretaceous period to the early evolution of the Atlantic Ocean (similar to the greenhouse state), the deep water of the ocean could not be forever flowing. There would inevitably be deep water forming to replace the original deep water positions. The density difference caused by saltiness became the main deep-water formation mechanism, and the thermohaline circulation was strong, which could transfer heat from low latitudes to high latitudes efficiently.

World's biggest greenhouse
There were many large-scale greenhouses in the world. There were 27 greenhouses in the world, one of the largest greenhouses in Denmark; the largest greenhouse agricultural base in the world, covering an area of 26000 hectares, was located 30 kilometers southwest of Almeria in Spain; and the greenhouse in the Royal Botanic Gardens in West London, covering an area of 121 hectares along the River Thames in the United Kingdom, was one of the largest greenhouses in the world.
The reason why gases are easily liquefied
The reason why gases were easily liquefied was mainly related to the intermolecular forces. For some gases, such as Cl2, its melting and boiling point is relatively low, and it is easy to liquify at a pressure of 101kPa and a temperature of-34.6 ° C. The relative molecular mass of Cl2 was relatively small, and the van der Waals force between the molecules was small. This intermolecular force was easily destroyed and liquefied. The reason why the nitrogen gas was easy to liquify was because it contained hydrogen bonds in its molecules, which increased the interaction force between the molecules. Therefore, the nitrogen gas could be liquefied at room temperature. In general, the intermolecular forces (including van der Waals forces, hydrogen bonds, etc.) were weak and easily changed under certain temperature and pressure conditions, which was the main reason why gases were easy to liquify.

Stories about Solids, Liquids and Gases Online
There are many interesting online stories about solids, liquids and gases. For example, there are stories that explain how water (a liquid) can turn into ice (a solid) when the temperature drops. This is a simple yet fascinating transformation that shows the different states of matter. Another type of story might be about how gases like oxygen are essential for life on Earth. These stories can be very educational for students learning about the basic concepts of matter.
