Do you think that the wind, which could have cooled the earth a little, was intercepted to generate electricity, resulting in the earth not being able to dissipate heat enough and warming?
This is impossible, not the greater the wind, the lower the temperature, the atmosphere from the troposphere to the fugitive layer, the greater the wind speed is the outward, but the temperature is not always dropping, the principle of wind formation upstairs is a very large scale, the landlord you said that the temperature gradient is vertical, and the wind you refer to is blowing horizontally, these are two unrelated phenomena.
To understand this problem, you still need to have a complete understanding of the entire atmosphere and the movement of the earth before you can figure it out.
In addition, typhoons and cold waves are exchanges within the earth system, and have nothing to do with the overall temperature of the earth!
Moreover, typhoons are warm structures that are generated on the surface of the tropical ocean, so they are not ...... heat dissipationThe typhoon is coming, there are many clouds and no sun, and it is raining and the wind is blowing, do you feel cold?
Among the many factors contributing to global warming, this will never happen.

Although the use of wind energy can reduce the generation of heat, the consequence of the work done by using wind energy is also work, which is generally dissipated in the form of heat, but the form has changed, and the total energy is still conserved, so there is no such thing as using wind energy to reduce the temperature of the earth.
However, if we can make full use of wind and solar energy, it means that we will use less other energy sources, unless the scale of renewable energy is large enough to use only a small amount of non-renewable energy, which means that the earth does not produce additional energy, which will also help to reduce the temperature.

We can protect the environment, we can not litter, we can not burn garbage, etc.
-
We should try to avoid environmental damage, and when using some things, we should be environmentally friendly and energy-saving, do not emit some toxic gases into the air, and try to take some public transportation and travel green.
-
We usually don't litter, we must do a good job of garbage classification, usually try to drive as little as possible, and reduce exhaust emissions.
-
We can start from the small things around us, don't waste food, take care of some animals and plants, separate garbage, and reduce carbon emissions.

1) Sea level rise.
History proves that in the 20th century the global sea level rose by 10 15 cm. Based on the current rate of greenhouse gas emissions from human activities, it is estimated that sea levels will be higher by mid-century than they are today. The direct impact of sea level rise is as follows:
The lowlands are flooded; Coasts are eroded; poor flood drainage; land salinization; seawater inflow, etc.
Currently, about 1 3 of the world's population lives within 60km of the coastline, and 20 of the world's 35 largest cities are located along the coast.
2) Effects on flora and fauna.
Plants and animals have responded to historically slow climate change, either adapting to or becoming obsolete. Those who exist are adaptors, but they only adapt to the slow changes that have occurred in the past over many centuries. For example, since the late Quaternary Ice Age, the surface ice retreated northward, and the temperature rose for thousands of years5, and the oak forests of the southeastern United States gradually migrated northward.
Due to anthropogenic CO2
The scale of climate warming due to increased emissions is similar to the above, but it has occurred in a century. During this period, the climate zone warms and moves hundreds to thousands of kilometers to higher latitudes. However, the flora and fauna of nature, especially plant communities, may be doomed by the inability to adapt and transfer at a commensurate rate.
Climate scenarios at CO2 doubling estimate that the southern boundary of North American forests will retreat 600 700 km to the north. However, based on the historical rate of forest migration, even if it were doubled, the northern edge of the forest would only move north by 100 km in 100 years. Future climate change will cause some species to disappear in some areas, while others benefit from warming, with more habitat and fewer competitors and predators.
and 3) the impact on agriculture.
Preliminary studies suggest that global warming will cause a northward shift in the temperature zone, which in turn will lead to a corresponding change in atmospheric motion, and a consequent change in global precipitation. In general, such an increase in temperature leads to an increase in potential evaporation and a weakening of the meridional circulation, with increased precipitation in the existing rain bands at lower latitudes, more snowfall in winter at higher latitudes, and less precipitation in summer in mid-latitudes. Increased precipitation is beneficial for most dry and semi-arid regions, but for areas with reduced precipitation, such as central North America and inland northwest China, it will become more arid due to reduced summer rainfall, leading to desertification.
In addition to this, global warming will also exacerbate natural disasters such as high temperatures, heat waves, tropical storms, and tornadoes. As a result, the stability and distribution of world food production will change significantly as global temperatures rise. Warming temperatures have caused changes in the structure of agriculture, which will lead to corresponding changes in the patterns of many agricultural products.
4) Effects on human health.
Global warming will cause increased morbidity and mortality in humans, and infectious diseases such as schistosomiasis and dengue fever will endanger many areas.

The ground absorbs solar (shortwave) radiation, and the temperature rises, producing terrestrial radiation - longwave radiation (physical knowledge: when the temperature of the object is heated, radiation will be generated; The higher the temperature, the shorter the wavelength and vice versa); Because ground radiation is long-wave radiation, most of it is absorbed by carbon dioxide and water vapor in the atmosphere (lower atmosphere), which warms the atmosphere; Atmospheric warming, the production of atmospheric radiation (long-wave radiation), of which a larger part of the atmospheric radiation is directed to the ground, because this part of the atmospheric radiation is in the opposite direction of the ground radiation, so it is called atmospheric inverse radiation, atmospheric inverse radiation to the ground due to the ground radiation loss of heat to compensate for the ground, so the atmospheric inverse radiation to the ground has played a role in insulating the ground The trend of global temperature in the past hundred years is that the temperature is rising, the climate is warming, and the greenhouse effect is enhanced According to the analysis of the atmospheric heating process in the figure, the figure in It is the weakening effect of the atmosphere, it is the solar radiation, it is the ground radiation, it is the atmospheric inverse radiation, so the trend of global temperature in the past 100 years is that the temperature is rising, the climate is warming, the greenhouse effect is increasing, and the role in the figure is enhanced

Some experts say that due to global warming, once-in-a-century extreme weather may become a once-in-a-decade frequent event, such as a super typhoon, severe drought, and "violent plum" as soon as a typhoon appears.
Judging from the various natural disasters that have occurred frequently in recent years, this topic is indeed very worthy of the attention of the whole people. The frequency of extreme weather events due to global warming is only one of the triggers, and this is the data that many meteorologists have made based on the various types of extreme weather events they have collected. And after compiling the data into graphs, we found that the serious consequences of climate change for human beings were discovered.
The impact can be devastating. This will only increase for a long time to come. The various disasters caused by global warming in the past will have a huge impact on human society.
Therefore, in order to regulate the continuation of global warming, we should work together.
1. Reduce carbon dioxide emissions. Reduce the air pollution caused by the emission of factories and automobiles;
2. Try to save energy in the use of various household appliances;
3. Forests are the most important respiratory organs of the whole earth, and they are of great help to maintain the ecological environment of the earth. It also plays a role in preventing soil erosion, desertification, and air purification.
4. Vigorously develop product recycling and avoid the new energy required for the production of new products.
5. Garbage classification is also a matter that the whole people should pay attention to and actively participate in.
6. Water is one of our indispensable and important resources, and it is urgent to protect water sources and the environment.
7. Eat more vegetarian food and less meat. It avoids the pollution caused by animal husbandry to the environment.
In fact, no matter what kind of call and initiative, everyone should actively participate in the maintenance, after all, there is only one earth. This is the home of all human beings, not the business of one person. Don't hold on to global warming, which is something that future generations will face and bear, and it will affect future generations.
Such a thought is extremely undesirable. The most important thing to do is to work together to create a better home.
-
We should protect the environment, pay attention to garbage classification, try to travel green, and reduce carbon dioxide emissions.
-
Stop littering and protect the environment. Plant more trees. Reduce some CO2 emissions. In this way, the rate of global warming can be reduced.
-
The first thing is to protect the environment, and never litter anywhere, and then don't litter cigarette butts, and be sure to save water and energy.
-
It is still necessary to protect the environment and reduce carbon emissions, so as to effectively alleviate global warming.
-
This requires us to take the bus when we travel daily, not to drive a private car, and not to litter, so as to reduce environmental pollution and reduce carbon dioxide emissions.
-
We must protect the environment, do not litter, and do not use disposable items, do not trample on lawns, cut down trees, and do green travel.
-
Plant more trees, let yourself have more and more green plants around you, don't discharge pollutants into the environment, and make the environment green.
-
We must drive less when we usually travel, because the exhaust fumes emitted by cars have a great impact on air quality, and once the air quality drops, then it will warm the air, thus affecting global warming.

Extreme weather occurs frequently, bringing great disasters to human beings。In Gansu, 21 athletes were killed due to extreme weather. In the north of our country, there are often sandstorms, and the United States also has extremely cold weather, and the occurrence of these extreme events is affected by global warming.
Extreme weather knows no borders, and climate issues are also a severe test for mankind. Extreme weather is happening in many countries, and to reduce the occurrence of extreme weather, it is necessary to slow down global warming. <>
Global warming leads to frequent extreme weather events and delays global warming, not in a day or two, just as global warming is not caused in a single day. As a member of the earth, human beings are becoming more and more concerned about changes in the environment. But global warming is happening beyond imagination, and sea levels are rising.
Little by little, it devours the land of human beings, and if everyone lets it go, it will not only hurt the plants, but also the home for their own survival. <>
To avoid global warming, global warming is closely related to human beings, and if ordinary people want to delay global warming, they must reduce carbon emissions. Many industrial productions produce a large amount of carbon, and arbitrary emissions will accelerate the process of global warming. In ordinary times, everyone should also pay attention to saving in terms of clothing, food, housing and transportation.
For example, if you have old clothes at home, don't throw them away at will, you can donate them to institutions for secondary use. <>
What can the average person do? When buying furniture, you can also buy second-hand ones, which is more environmentally friendly. You can plant more greenery to make our home more beautiful.
It is also necessary to save water resources and use the water used to mop the floor. You can walk more often, or ride a bicycle to reduce the chance of driving a car. When renting a building, you can also take the stairs and avoid taking the elevator.
As long as everyone begins to pay attention to environmental protection and care for the environment, then global warming will be delayed, so that our home will be better and better.
-
As an ordinary person, in fact, you can only save water in your daily life, save the use of electricity, reduce some car exhaust emissions, and often plant trees.
-
What ordinary people should do well is low-carbon travel. You can take the bus to work. In this way, we can reduce carbon dioxide emissions and stop the trend of global warming.
-
Don't litter, be sure to separate the garbage when throwing it, don't trample on the lawn, don't cut down trees, and don't use disposable utensils.
-
Ordinary people should save water resources in normal times, and then don't throw garbage bags everywhere, and be sure to take care of the environment.
-
Ordinary people can be environmentally friendly in all aspects of life, go green, use less disposable plastic bags, save water and electricity, throw garbage in a regular way, and so on.
-
Ordinary people should protect the environment, start from small things, try not to litter, a small step for people is a big step for society.
-
Ordinary people can do some things within their means, such as not wasting food when eating, sorting garbage when throwing garbage, and caring for some plants.
-
We ordinary people must save water, do not litter, and better protect the environment, so as to avoid global warming.
-
Protect our most basic ecological environment, and reduce pollution, try to travel green, low-carbon life, and start from the most basic small things.
The solutions to global warming are as follows: >>>More
Since the end of autumn 2009, heavy snowfall, strong cooling, and cold waves have taken turns, causing the temperature in Beijing and even in North China to drop again and again, and the maximum temperature dropped to January 4, 2010, which is the lowest value of the highest temperature in early January since 1951. From January 2 to 3, 2010, the snowfall at the observatory in the southern suburbs of Beijing reached 10 mm, the largest daily snowfall for the same period since 1951. >>>More
According to scientists' research, if the earth's temperature rises by 1 degree, the United States will become a desert, and the Sahara Desert, the hottest in the world, may become a sea of fertile land. When the temperature rises by 6 degrees, the earth will face a final catastrophe like the prehistoric mass extinction, with 95% of species extinct, and will humans still be there? >>>More
The world has indeed begun to warm, according to experts, in the past it took tens of thousands of years to rise 1 degree Celsius, and now the temperature has risen in just 100 years, which can't help but make people think of the damage caused by the rapid development of human society after the industrial revolution, and now most of the views are that the carbon dioxide emitted by industrial production causes the atmosphere to heat up, because it can cause the atmosphere to heat up, and there is also a view that global warming is a cyclical change of tens of thousands of years or even hundreds of millions of years, not all caused by human beings, And humanity is only speeding up this process of warming. So for us now, since global warming has already happened, we should actively remedy it, instead of arguing about what caused it.
