What harm is the increase in the temperature of the earth s surface causing us?

Greenhouse gases make the earth hot. Over the past 200 years, with the deepening of industrialization, it is an indisputable fact that a large number of greenhouse gases, mainly carbon dioxide, have been emitted, resulting in an increase in global temperature and climate change. On December 8, the World Meteorological Organization released the "State of the Global Climate 2009" report, which pointed out that the past 10 years have been the hottest in the world since records began.

In addition, global warming is causing Antarctic glaciers to melt, which in turn is causing sea levels to rise. According to a new survey published by Finnish and German academics, sea levels could rise by the end of the century, far more than previously expected. If this continues, the South Pacific island nation of Tuvalu could be the first island nation to disappear into the ocean.

A study published in the United States on December 5 pointed out that the earth's fever has also caused a huge crisis to human health. First, allergy studies have shown that spring allergies are aggravated by the fact that carbon dioxide levels and temperatures gradually increase and flowering comes on sooner, increasing pollen production. Second, species are becoming more and more "pocket-sized", with organisms becoming smaller as global temperatures rise, as seen in Scottish sheep.

Third, the increase in kidney stones, due to the increase in temperature and dehydration, researchers**, by 2050, there will be 2.2 million new patients with urinary stones. Fourth, the outbreak of foreign infectious diseases, the increase in the temperature of the water environment will lead to the proliferation of mosquitoes and plankton, and the outbreak of dengue fever, malaria and encephalitis will occur from time to time. Fifth, lung infections are aggravated in summer, and the temperature rises and the cool breeze decreases, which will exacerbate ozone pollution, which can easily lead to lung infections.

Sixth, algae overflows cause diseases, and rising water temperatures lead to the rapid growth of cyanobacteria, which can be contaminated from municipal water systems to natural lakes, causing diseases of the digestive system, nervous system, liver, and **. Low-carbon life has become a way of life that human beings urgently need to establish.

It's too troublesome to answer by yourself, so plagiarize it

Rising temperatures on the Earth's surface can cause serious harm:

The melting of ice at the poles and the rise of the water level have caused a decrease in land and the inundation of coastal cities, which directly affects the economic exchanges of countries around the world;

It also brings the occurrence of El Niño and the associated La Niña;

Increasing droughts will reduce crop yields, food shortages, and food crises and even wars.

The laws of biological growth are disrupted, the ecological environment is destroyed, and species become extinct.

Humanity is in the process of warming the climate after the melting of glaciers in the Quaternary period, just like the evolution of life in extinction over hundreds of millions of years, but it is just a cycle. And the development of humanity itself may accelerate this process. Hey hey

The water level will rise so that the country at the bottom of the altitude will be submerged.

The laws of nature can also be affected.

As glaciers melt at the poles and sea levels rise, lower elevations suffer first.

It's not that simple, the temperature of the sun is caused by the nuclear reaction in the inner core, and if the surface temperature increases, then the nuclear reaction in the inner core must be intensified. Then it is a sign that the sun has entered the aging process early. Then it's time to enter the stage of a white dwarf.

At that time, the sun will be extremely expanded, and the extension can completely surround the earth, and the earth will be no different from the current mercury at that time. It is recommended that you look for information about white dwarfs in SOHU, as well as the principle of the sun's nuclear reaction, and the current position of Mercury in the solar system. You will be clearer.

Rising temperatures, melting ice at the poles, and rising water levels will lead to a reduction in land mass, which can cause serious harm and lead to the emergence of El Niño.

Droughts have increased, the law of biological growth has been disrupted, and the ecological environment has been destroyed.

In the early days of the formation of the earth, the geocentric pressure generated by the gravitational pull of the earth's material made the temperature of the earth extremely high, leaving the whole earth in a lava state. As the heat is dissipated, the Earth's outer layers form a crust, but the temperature inside remains high.

Due to the decay of a large number of radioactive elements in the center of the earth, a large amount of heat is released, so that the earth always maintains a high temperature.

Due to the sun's irradiation and the thermal insulation of the atmosphere, the temperature of the earth's surface is much higher than that of the universe. The earth is larger in size and its heat is maintained for a long time.

Due to the rotation of the Earth, the solid and liquid cores of the Earth are in relative motion under the gravitational pull of the Sun and the Moon, and the friction in them constantly generates heat, keeping the Earth's core at all temperatures.

In the early days of the earth's formation, the geocentric pressure due to the gravitational pull of the earth's material made the earth's temperature extremely high, leaving the entire earth in a lava state. As the heat is dissipated, the outer layer of the earth forms the earth's crust, but the temperature inside is still high, while the crust forms as an insulating layer. The decay of a large number of radioactive elements in the center of the earth will release heat, so that the earth will always maintain a high temperature.

Due to the rotation of the Earth, the solid and liquid inner cores of the Earth are in constant relative motion under the gravitational pull of the Sun and the Moon. Motion friction generates a lot of heat. <

1. In the early stage of the formation of the earth, due to the gravitational force of the earth's materials, the temperature of the earth was extremely high, and the whole earth was in a lava state. As the heat is dissipated, the outer layer of the earth forms the earth's crust, but the temperature inside is still high, while the crust forms as an insulating layer.

3. Due to the rotation of the earth, the solid and liquid cores of the earth are in constant relative motion under the gravitational pull of the sun and the moon. Motion friction generates a lot of heat, so the temperature of the center of the earth is high.

The Earth's temperature is high because a lot of the Earth's heat was left over from the Earth's formation 4.5 billion years ago.

For the past billions of years, the Earth has generated heat on its own inside. The current theory generally holds that the Earth was formed by accretion, and that after the Earth was formed, meteorites attracted each other to form larger objects, which in turn attracted larger matter, until it reached its current size.

This process accumulates a lot of heat, just like when two objects collide to produce heat, imagine if both the hammer and the stone get hot when the hammer hits the stone. This heat is enough to heat the Earth to a molten state, and it has not completely dissipated to this day, accounting for about 10% of the total heat in the Earth's interior today.

The Earth's temperature may have dropped a few times over the past few billion years, but now the Earth is close to a stable state of temperature because it generates its own heat internally. It has been losing heat since the Earth was formed billions of years ago, but now it produces almost as much heat as it loses.

Surface temperature**.

Nowadays, the heat generated inside the earth and the heat lost to the outside are basically in a state of equilibrium, so the temperature of the earth is relatively stable, but the surface temperature of the earth is mainly affected by the sun, because the heat obtained by the earth from the sun is thousands of times that of the heat emitted from the interior by the earth itself. So although the interior of the earth is very hot, the heat that life on the surface depends on is still the sun.

1. Decay of radioactive elements. For example, elements such as U, Th, and K have some radioactive isotopes, which produce a lot of heat when decaying. The generation of this energy is mainly concentrated in the continental crust, accounting for about half of the surface heat flow in continental areas.

Although it is now theorized that the mantle and core contain low levels of radioactive elements, due to their large size, heat production is also considerable.

2. Gravitational potential energy. In fact, in the interior of the earth (especially in the lower mantle and core), there has been a downward migration of heavy matter, and its gravitational potential energy is converted into heat energy. This process was even more severe in the early days of the Earth.

Probably, during the early accretion of the Earth, the heat converted by gravity also contributed.

3. Latent heat. The outer core of the Earth is a liquid, but it has been crystallizing and solidifying, and some substances have changed from liquid to solid crystals, which will release some heat.
