Is the greenhouse effect good or bad? The dangers of the greenhouse effect

Consequence. 1) an increase in pests and diseases on the planet;

2) sea level rise;

3) abnormal weather and an increase in ocean storms;

4) The land is arid and the area of desertification is increasing.

Scientist**: If the increase in the temperature of the Earth's surface continues at the current rate, by 2050 the global temperature will rise by 2.4 degrees Celsius, the icebergs of the Arctic and Antarctic regions will melt significantly, causing a significant rise in sea levels and the flooding of some island countries and coastal cities, including several well-known international cities: New York, Shanghai, Tokyo and Sydney.

The harms of the greenhouse effect include: global warming, increasing pests and diseases on the earth, rising sea levels, desertification, lack of oxygen, disappearance of tropical rainforests, and the arrival of new ice ages. Humanity should do everything in its power to reduce carbon dioxide emissions and curb the rising trend of the greenhouse effect.

The dangers of the greenhouse effect

The greenhouse effect, also known as the "flower house effect", is a common name for the atmospheric insulation effect.

The most direct cause of the greenhouse effect is that human beings burn too much coal, oil, natural gas, etc., which produces and emits a large amount of carbon dioxide.

The greenhouse effect has two characteristics, one is that the indoor temperature is high, and the other is that it does not dissipate heat.

The fundamental reason for the greenhouse effect is that the earth will emit a longer electromagnetic wavelength, and these ground long-wave radiation will be strongly absorbed by the earth's atmosphere when it passes through the earth's atmosphere, and at the same time of absorption, the earth's atmosphere will radiate outward longer radiation than long-wave radiation, and then part of it will go down to the ground to become inverse radiation, and the ground will heat up after receiving this inverse radiation. Carbon dioxide prevents surface heat from radiating into space and has the function of regulating the earth's air temperature. Without carbon dioxide, the Earth's average annual temperature would be 20 percent lower than it is today.

However, if the carbon dioxide content is too high, the earth will feel like it is in a pot, and the temperature will gradually rise, forming a "greenhouse effect".

Nowadays, due to the gradual modernization and industrialization of our society, a large amount of carbon dioxide gas is emitted into the atmosphere, causing the greenhouse effect to become more and more serious.

The greenhouse effect can make prehistoric deadly viruses threaten humanity.

Scientists in the United States recently warned that due to the melting of the Arctic ice due to the rise in global temperatures, the deadly prehistoric virus that has been frozen for more than 100,000 years may resurface, causing the world to fall into epidemic panic and seriously threaten human life.

Scientists from Syracuse University in New York pointed out in the latest issue of the Journal of Scientists that they have earlier discovered a plant virus, TOMV, which is also presumed to be found in the Arctic ice due to its widespread spread in the atmosphere. Researchers then took four blocks of ice from Greenland, ranging in age from 500 to 140,000 years, and found the Tomv virus in the ice. Researchers say the virus is surrounded by strong proteins on its surface, so it can survive adversity.

The new findings have led researchers to believe that a series of epidemic viruses, such as polio, polio and smallpox, may be hiding deep in the ice, and that humans are currently incapable of protecting themselves against these primitive viruses, and that when the ice melts due to rising global temperatures, these viruses buried in the ice for thousands of years or more may resurrect and form epidemics.

It can get especially hot in the house.

Hazards and consequences of the greenhouse effect:

The consequence: the Earth's glaciers are receding, sea levels are rising, and climate zones are shifting northward, causing ecological problems.

The hazards are: it will cause sharp weather changes in local areas in a short period of time, resulting in abnormal climate, resulting in high temperatures, heat waves, tropical storms, tornadoes and other natural burial disasters; It will also lead to an increase in the frequency of extremely hot weather, while also accelerating the spread and spread of epidemic diseases, which directly threatens human health.

Causes of the greenhouse effect:

1. The concentration of carbon dioxide increases.

The amount of carbon dioxide in the air is increasing day by day, because the increase in carbon dioxide is causing the earth's climate to rise in temperature. The main reason for the increase in carbon dioxide is the use of a large amount of resources such as coal, oil, and natural gas. Collapse of the town.

2. Forest harvesting.

Trees absorb carbon dioxide from the air, reducing carbon dioxide concentrations and releasing oxygen. And because humans around the world are cutting down a large number of trees, the number of trees that can absorb carbon dioxide has greatly decreased, and the concentration of carbon dioxide has increased.

3. Population increase.

The population is increasing too fast and the resources are insufficient, which will also lead to serious environmental pollution. Trees are also cut down to provide space and daily necessities for a growing population, so population growth is the primary cause of global warming.
