The consequences of global warming are:

Answer] B Answer Analysis] Question Analysis: Global warming will cause glaciers to melt, causing sea levels to rise, causing coastal lowlands to be flooded; Global warming will increase precipitation in most areas of the middle and high latitudes of the Northern Hemisphere, which will extend the cultivation areas of the northern temperate zone to the high latitudes, but most of the arid and semi-arid regions will become drier due to enhanced evaporation. Global warming may bring some benefits to local areas, but on a global scale, the cost of adjusting the economic structure of human society to climate change will be higher than the possible benefits.

Test point: This question examines the consequences of global climate change.

Comments: This question is less difficult, and the key to solving this question is to clarify the causes and consequences of global climate change. The impact of sea level rise on the geographical environment and human life of the world's coastal zones is mainly manifested in the following aspects:

Rising sea levels will inundate low-lying tidal flats and wetlands. Seawater intrudes into inland rivers, making the water quality salty and even undrinkable; On the one hand, the discharge of land sewage is blocked, which affects the purification degree of river water, and on the other hand, it will prolong the waterlogging time, so that the flood disaster will be aggravated. intensified storm surge action; intensifying coastal erosion; Sea level rise will cause seawater inflow, and the salinity of groundwater will increase, which will easily cause land salinization. In addition, it will also affect the functions of ports and waterways.

What will be the consequences of continued global warming? The answer is unexpected.

causes the Earth's temperature to rise, known as the greenhouse effect. Global warming will redistribute global precipitation, melt glaciers and permafrost, and rise in sea levels, which will not only jeopardize the balance of natural ecosystems, but also affect human health and even threaten human survival.

On the other hand, due to the increase in continental temperature caused by terrestrial greenhouse gas emissions, the temperature difference between the continent and the ocean has become smaller, which in turn has slowed down the air flow, and the haze cannot be blown away in a short time, resulting in an increase in haze weather in many cities, affecting human health. Measures such as restricting the movement of automobiles and suspending production have only short-term and partial effects, and cannot fundamentally change climate warming and smog pollution.

Ecological impacts of global warming.

First, global warming has led to rising sea levels and a redistribution of precipitation, changing the current world climate pattern. Second, global warming has affected and destroyed the biological and food chains, bringing more serious natural consequences.

For example, there is a migratory bird that flies from Australia to Northeast China for the summer every year, but due to global warming, the temperature in Northeast China has increased, and the summer has been extended, and the time for this bird to leave Northeast China is correspondingly delayed, and the time to return to Northeast China is also delayed accordingly.

As a result, a pest that eats migratory birds has flooded and destroyed large areas of forest. In addition, there has been an increase in extreme environmental events, such as droughts and floods.

Harm to the environment:

1. Melting glaciers (mainly the effects of continental glacial melting) have caused global sea levels to rise, threatening countries with lower coastal elevations or more economically developed areas.

2. It may increase the frequency of extreme weather, such as drought, flood, extreme temperature, etc., which will affect the survival of organisms, and the precipitation in low-latitude areas may decrease, which will have a greater impact on agriculture.

3. Affect the global ecosystem, change the ecological environment and accelerate the rate of biological extinction.

Harm to humans:

1. The rise in temperature will provide kinetic energy to the air and the ocean, forming super-large typhoons, tsunamis and other disasters. Every year, more and more disasters will be faced, and at the same time, typhoons and tsunamis will also damage buildings and threaten human life, and will also bring mudslides and landslides, causing huge hidden dangers to human beings.

2. The rise in temperature will also lead to a significant reduction in grain and feed production in inland areas, and the shortage of grain and meat.

3. The accumulation rate of melting icebergs when the temperature rises is not as fast as the melting rate returns, so the icebergs are not accumulating, and we have no fresh water to drink.

4. The rise in temperature has gradually broken the food chain in nature.

5. The increase in the content of carbon dioxide in the atmosphere will also lead to an increase in the content of carbon dioxide in the ocean, which will carbonate the ocean and kill microorganisms, so that the marine food chain will be broken, and a large number of marine organisms will die.

6. The rise in temperature will also cause many invertebrates to wake up from hibernation, and then these insects will miss the opportunity to hunt and die in large numbers, and eat a large number of forests and crops due to the early awakening of insects.

7. At the same time, the increase in temperature will also affect the functions of the human body, the probability of getting sick will be higher and higher, and various physiological diseases will spread rapidly.

8. The rise of temperature, the melting of glaciers and the rise of sea level have caused the loss of ecological groups such as coastal tidal wetlands, mangroves and coral reefs, coastal erosion, seawater intrusion into coastal underground freshwater layers, and salinization of coastal land, resulting in imbalance in the natural ecological environment of coasts, estuaries and bays, and bringing disasters to the ecological environment of coastal zones.

This is due to the increasing number of people buying cars and the increasing number of industrial emissions, which is causing air pollution and contributing to global warming.

1. The mining and utilization of petroleum and coal produces a large amount of carbon dioxide, sulfur dioxide and other gases, which enter the air without restrictions, thus causing the temperature to rise.

2. Production and application of various chemical raw materials.

3. The development of a large number of breeding industries (cattle, pigs, chickens, ducks, etc.), and the unrestricted use of agricultural fertilizers and pesticides.

4. Mining of a large number of mineral deposits and the use of building materials.

5. The continuous increase in population and the massive consumption of agricultural products.

In industrial production, harmful gases are emitted, which affects the ozone layer. The ozone layer is getting thinner and thinner, and ultraviolet rays hit the ground, unable to filter out too much ultraviolet light. At the same time, after the greenhouse effect, the earth-atmosphere system is unstable, the absorbed energy and the emitted energy cannot reach a balance, and the heat accumulates, which eventually leads to global warming.

Global warming has a variety of effects, starting with the melting of glaciers in the North and South Poles. Many small animals have lost their habitat, sea levels are gradually rising, and coastal residents are affected to a greater or lesser extent.

The climate in the North and South Poles is cold, and humans cannot live in the North and South Poles for long, but penguins and polar bears have lived in the Antarctic and the North Pole for tens of thousands of years. Glaciers not only ensure that penguins and polar bears have proper living space, but also balance the temperature. When global temperatures warm, they will take on a different state.

Large amounts of glaciers are melting into water, and little penguins and polar bears are losing their homes. Have you ever seen a polar bear trapped on a piece of ice, this is actually a typical example.

When large amounts of glaciers melt into water, water flows into the ocean, eventually causing sea levels to rise. For coastal cities or residents of coastal cities, rising sea levels can cause a range of inconveniences. If the sea level rises too much, it will eventually lead to the inundation of some coastal cities.

Urban development is constrained, and people are constantly required to increase the height of their levees.

Overall, with the multiple effects of global warming, many countries have begun to protect the environment, mainly by reducing exhaust emissions. On the other hand, the many effects of global warming have greatly affected the organisms of the North and South Poles. Global warming leads to an increase in the Earth's temperature, especially the rate at which glaciers are melting.

When organisms lose their habitat, nature loses access to food, affecting biodiversity.

Causes of global warming: first, gas changes, the content of carbon dioxide in the gas increases year by year with the destruction of nature by human beings, second, ozone changes, with the progress of human science and technology, the chemical substances used are becoming more and more diversified, such as the fluorochloron used in old air conditioning and refrigeration has a very huge damage to ozone.

The Dangers of Global Warming:

1. Sea level rise. Endangers coastal areas around the world, especially those densely populated and economically developed estuaries and coastal lowlands.

2. Affect agriculture and ecology. It may increase photosynthesis in plants, prolong the growing season, and make some parts of the world more suitable for agricultural farming.

The main reason is that the environment is destroyed, and if global warming, the atmosphere will be destroyed, the ice in Antarctica will melt, the sea level will rise, and cities and farmland in coastal areas will be flooded.

It may be that there is a lot of garbage, but now there is a lot of garbage, and after warming, there will be various diseases.
