What is the greenhouse effect? What are the hazards?

The greenhouse effect, also known as the "greenhouse effect", is a common name for the atmospheric heat preservation effect. The atmosphere can make the short-wave radiation of the sun reach the ground, but a large number of long-wave radiation rays emitted by the ground after heating are absorbed by the atmosphere, which makes the interaction between the ground and the low-level high temperature similar to the greenhouse for cultivating crops, hence the name greenhouse effect.

Danger:

1, global warming

The increase of greenhouse gas concentration will reduce infrared radiation to outer space, so the earth's climate needs to be changed to achieve a new balance between absorbing and releasing radiation.

2. The increase of pests and diseases on the earth.

The greenhouse effect can make prehistoric deadly viruses threaten human beings. American scientists have warned that the prehistoric deadly virus that has been frozen for more than100000 years may reappear, leading to a global epidemic panic and a serious threat to human life.

3. Hypoxia

In a word, the molar mass of greenhouse gases is greater than that of oxygen. Although all the energy on the earth has been safely exploited and utilized by all countries in the world, the final state of the environment on the earth is similar to that of the earth 654.38 billion years ago. At that time, not only wild animals could not breathe oxygen, but even humans could not survive.

Extended data

Countermeasures:

1, encourage the use of natural gas.

Encourage the use of natural gas as the main energy source. Because natural gas emits less carbon dioxide. Japanese cities also generally use natural gas instead of liquefied gas, and this case is to further promote this movement. However, the effect of inhibiting warming is not too great, and only about 1% at most.

2. Exhaust limitation of steam locomotive

Because the tail gas of steam locomotive contains a lot of nitrogen oxides and carbon monoxide, it is hoped to reduce its emissions, and by 2050, it can share about 2% of the inhibitory effect on temperature rise.

3. Encourage the use of solar energy.

For example, promoting the so-called "sunshine plan" and so on. This kind of effort can relatively reduce the consumption of fossil fuels, so it has a direct effect on reducing the greenhouse effect. However, even if this plan is actively promoted, it will only inhibit the temperature rise to about 4% by 2050. Its effect does not seem to be as expected.
