What is the connection between the greenhouse effect and global warming

First, the reasons are different

1. Greenhouse effect.

Of the energy delivered from the sun to the Earth, about 1 3 of the energy is reflected back into space through the clouds and the Earth's surface. The rest is absorbed by the land and the sea, and then emitted in the form of infrared rays, which are then absorbed by polluting gases (trace gases) in the atmosphere, which in turn release infrared rays upward.

The lower side is released to the surface of the earth.

2. Global warming.

Global warming is due to carbon dioxide in the atmosphere.

It is caused by a sharp increase in greenhouse gases and a large amount of infrared long-wave radiation from the ground, which in turn enhances the greenhouse effect.

Second, the harm is different

1. Greenhouse effect: Global warming will lead to more and more extreme weather such as droughts and typhoons. Global warming will lead to an increase in ozone concentrations in low air, affecting human health.

2. Global warming: global warming, the increase of pests and diseases on the earth, and the rise of sea level.

Land desertification, lack of oxygen, tropical rainforest.

Disappearing, new glacial periods.

coming, etc. Humanity should do everything in its power to reduce carbon dioxide emissions and curb the rising trend of the greenhouse effect.

Mitigations:

Unless humanity's current efforts to reduce emissions are successful, the only way to cool the planet in the future is to adopt a geoengineering approach. Geoengineering technology is considered the ultimate solution to global warming, but some people are in favor of its idea because it is too "crazy", and many more are firmly opposed because of the "difficult consequences" it may have.

When the global temperature reaches the warning value and cooling measures have to be taken immediately, solar radiation management technology can be used; But it is not a substitute for decarbonization technologies when it comes to reducing greenhouse gases.

Global warming. It will change the entire ecosystem.

The destruction of the natural laws of the biological chain and the food chain has made the competitiveness of different populations within the original ecology disappear. For example, the hibernation time of rural animals will be shortened and extended.

Global warming will increase the global average temperature, and the contour line will move towards higher latitudes. This has allowed crops to grow in larger areas, allowing some crops that would not have been available in winter to grow today. In this area, the countryside should have been able to sow seeds in previous years, but due to the influence of the weather, the frozen soil or drought period has become longer, and the temperature may be high.

The inability to cultivate land in a timely manner makes it difficult for farmers to have land and cannot plant. High temperatures can also cause pests and diseases, affecting yields.

This has led to widespread drought in land-based areas, which has reduced food production, as well as fodder production. Grain and meat will be scarce, which is not conducive to the accumulation of sugar and the slow expansion of fruiting, and also means the best altitude for cultivation.

Change. Extreme weather events are on the rise, floods and droughts are frequent, and pests and diseases are on the rise. Internationally, the polar ecosystems have been disturbed and sea levels have risen.

Some lower countries are in danger of being submerged by the sea.

<> from the news in recent days, it can be seen that the temperature in Antarctica exceeds 20 degrees Celsius.

Climate warming will cause glaciers to melt, and at the same time, large numbers of "glacial viruses" will be released. Global warming.

This has led to a rise in sea levels and a redistribution of precipitation, altering the current world climate pattern; This also indirectly brings more serious natural consequences to the biological chain and the food chain.

The impact of global warming on agriculture is huge and far-reaching, although there are advantages and disadvantages, but the disadvantages always outweigh the advantages, and if the climate temperature gradually rises, agriculture will take more risks, and global food production will be reduced. In conclusion, the impact of climate change on agriculture cannot be ignored. In fact, the measures are very simple, do not destroy the existing forests and return farmland to forests, return grazing to forests, etc., with more plant photosynthesis, more greenhouse gases can naturally be processed.

Global warming affects the growth quality and yield of crops. Because climate warming will have a significant impact on the growth period of crops, under the conditions of climate warming, without new adaptation technologies, the growth period of crops will be shortened, and the growth will be reduced, which will offset the effect of the extension of the growth period of crops throughout the year, and due to the shortening of the growth period, the time for crops to accumulate dry matter through photosynthesis will be reduced, and the quality will also be reduced, which will have an impact on crop yields.

There are pros and cons to the impact of a warming climate on agriculture. The warming of winter makes some crop diseases and pests easy to overwinter, and the number of reproductive generations increases. Warming will also exacerbate the prevalence of pests and diseases and the spread of weeds, expand the geographical distribution of some pests and diseases, and increase the input of agricultural costs such as pesticides. Climate warming also shortens the growth period of crops, which may reduce yields; Climate warming may also lead to an increase in crop water demand and an increase in the likelihood of drought; The increased frequency of extreme weather events caused by climate change will further increase and intensify the impact of drought and flood disasters on agricultural production. In addition, climate warming will increase the amount of fertilizer, which will not only increase farmers' input, but also cause harm to the soil and the environment due to the increase of volatilization, decomposition and leaching loss.

The output of the three major staple crops, rice, wheat and maize, continued to decline; Any further increase in temperature will hinder or even interrupt photosynthesis, which will have a fatal impact on crop production.

The global climate is not simply warming, but a chaotic climate, with abnormal temperatures, high and low, moving to two extremes, which is the key issue in determining the causes of global climate change. Cause global climate chaos, the temperature is abnormal is drought, not the greenhouse effect, arid areas absorb and release the heat of the lead sun is very strong, constantly produce hot air masses to impact the atmosphere, in addition to causing the temperature of the atmosphere to rise, but also cause atmospheric circulation disorder, the extreme year of the chaotic end of the weather increases, the surrounding water vapor can not pass to the arid areas, resulting in uneven drought and flood, which is the impact of reality. The rise in global temperature will accelerate the melting of polar and inland glaciers, leading to a shift in the position of the Earth's center of gravity, causing a shift in the position of the Earth's axis, a deflection of the Earth's rotation, and an increase in the frequency of volcanic eruptions.

With the deterioration of the global climate, the shift of the position of the earth's axis, the polar and inland glaciers will further accelerate the melting, the polar glaciers will all melt, the position of the earth's center of gravity will be greatly shifted, the position of the earth's axis will be redetermined, the earth will be overturned, the global latitude and longitude will change, the direction of the earth's crustal movement will change dramatically, super ** and large-scale volcanic eruptions, the redistribution of sea and land, the change of ocean current circulation and atmospheric circulation pathways, and the global environment and climate will change dramatically, bringing extinction disasters to human beings.
