The higher the carbon dioxide concentration, the fewer cumulus clouds in the sky

Generally speaking, in our daily life, the higher the temperature, the more water evaporates. But for the first time, a team of researchers from Germany and the Netherlands found that this was not always the case, using a new atmospheric model: although the climate becomes warmer as the concentration of the greenhouse gas carbon dioxide increases, it can also cause plants with billions of tiny leaf stomata to evaporate very little water, which affects the gas and moisture content of the surrounding air, leading to the formation of fewer cumulus clouds, which exacerbate climate change when sunlight hits the surface.

"We want to know how the predictable rise in carbon dioxide concentrations in temperate regions affects cloud formation, and what role vegetation plays in this," said researchers in chemistry and meteorology at Wageningen University in the Netherlands and the Planck Institute in Germany. This is the first time that geophysicists have considered using computer models to study soil, water cycles, the atmosphere and plant growth.

The model results highlight how localized and everyday variable processes affect the atmosphere on a larger scale through (gas) turbulence. ”

The researchers simulated a climate change scenario: a 2 degree Celsius increase in the average global temperature would double the concentration of carbon dioxide in the atmosphere from the current level. The calculations describe the projected situation up to 2100.

Researchers have established some land-vegetation-atmosphere exchange processes in response to increased carbon dioxide and climate change.

When the concentration of carbon dioxide in the atmosphere increases, it actually initiates a cascade of physiological responses in plants. Plants regulate the exchange of water vapor and carbon dioxide by opening and closing the stomata of the leaves, and at higher carbon dioxide concentrations, the plants close the stomata. When carbon dioxide concentrations double, the stomata close prematurely because the plants absorb the necessary carbon dioxide for optimal photosynthesis, so less water is evaporated by the plants, and less water vapor enters the atmosphere overall.

As a result, fewer cumulus clouds will form. This means that, without the reflection of clouds, direct sunlight will make the Earth's surface warmer, and warmer air will create more turbulence in the surface atmosphere, resulting in more heat production and less moisture transfer. As a result, the response of plants to carbon dioxide concentrations causes the planet and atmosphere to warm, exacerbating climate change.

It seems like there is nothing to do with the two.

Oxygen and carbon dioxide in the atmosphere.

The reason why the amount remains relatively stable is photosynthesis.

In the early days of the Earth's formation, the amount of oxygen in the atmosphere was much lower than it is today, and after the emergence of green plants, the amount of oxygen in the atmosphere gradually increased.

Today, the proportion of gases is relatively stable, which is the result of photosynthesis absorbing large amounts of carbon dioxide from the air and releasing large amounts of oxygen. If photosynthesis stops, the oxygen on Earth will be constantly depleted.

Green plants use the sun's light energy to assimilate carbon dioxide (CO2) and water (H2O in the process of making organic matter and releasing oxygen, known as photosynthesis. The organic matter produced by photosynthesis is mainly carbohydrates.

and release energy.

As the carbon dioxide in the atmosphere increases, the temperature of the atmosphere increases, and at the same time, () Brother Lu.

a.As the surface water temperature increases, the seawater's ability to absorb carbon dioxide decreases.

b.The surface seawater temperature decreases, and the seawater's ability to absorb dioxide and attack carbon decreases.

c.The surface sea temperature decreases, and the seawater's ability to absorb carbon dioxide increases.

d.As the surface water temperature increases, the seawater's ability to absorb carbon dioxide increases.

Correct Answer: a

Answer]: C Answer] C. Analysis:

Carbon dioxide gas has the function of heat absorption and heat insulation. As a result of its increase in the atmosphere, it forms an invisible glass cover, so that the heat radiated by the sun to the earth cannot be reflected into outer space. Carbon dioxide is also known as a greenhouse gas.

The year-on-year increase in carbon dioxide levels leads to the greenhouse effect. Therefore, the answer to this question is C.
