The consequences of global warming, and what are the harms of global warming

According to Xinhua News Agency, researchers at the Worldwatch Institute in the United States recently warned that global warming will reduce global agricultural production, and food scarcity may occur in the next century. The researchers came to this conclusion after analysing information released by the United Nations and the National Academy of Sciences, as well as trends in the world rice market.

According to the Worldwatch study, global warming and declining groundwater levels will be the direct cause of the global food shortage, and the global rice trend reflects this.

Global warming will also cause sea levels to rise, and coastal areas will be inundated, as was the case with the previously known Great Western Continent.

Statistics released by the United States show that even in the face of last year's bumper global grain harvest and a decline in wheat and corn, rice was still up 30 percent to $260 per tonne.

A study published last year by the National Academy of Sciences showed that an abnormally high temperature rise during the rice growing season would reduce the harvest. In addition, declining groundwater levels and depleted wells in many parts of the world will also have an impact on food production.

Global warming is on the verge of a topless South Pacific island.

Global warming is causing the ice to melt rapidly in the Arctic and Antarctic, and sea levels are rising, with a World Bank report showing that even a small rise of 1 metre in sea level could be enough to turn 56 million people in developing countries into refugees. The world's first inhabited island, Cathari Island, located in the South Pacific country of Papua New Guinea, is about to be created, and the main roads on the island are waist-deep, and all the farmland is turned into mud.

Malaria is rampant in the accumulation of water in agricultural land.

The Cathari Islanders, who have always been happy in traditional costumes, have been independent for centuries and have always maintained their traditional lifestyles, but they are facing the fate of being submerged by the sea due to global warming caused by the destruction of the environment by humans. Paul Tabassi, an environmental activist on Cartery Island, said: "They have been attacked by the sea, and there have been constant floods, and the original areas have been altered, destroyed, and almost all places have been submerged by the sea.

At present, the main road on the island is waist-deep, and the farmland where coconut trees were planted is completely muddy. What's worse is that it causes mosquitoes and flies to overfestation and malaria to rage.

Expert**, in a few years, Cathari Island will be completely submerged in the sea, and it is imperative that the entire island residents move to the village.

The Amazon rainforest is fading away.

The Amazon rainforest, the world's largest tropical rainforest in South America, is disappearing, adding to the global warming crisis.

Known as the lungs of the earth, the Amazon rainforest covers 5% of the earth's surface, producing 20% of the world's oxygen and 30% of biological species, due to illegal logging and reclamation, the Amazon rainforest is retreating in an area of 7,700 square miles per year, equivalent to the size of a New Jersey, the loss of the rainforest will not only intensify global warming, but also make many organisms that can only survive in the rainforest face the danger of extinction, in the past 40 years, the rainforest has disappeared by half.

melting glaciers; sea level rise; El Niño and La Niña occur frequently.

The temperature balance of the whole earth after the warming of the earth then"Antarctica"Arctic"If the temperature rises, the icebergs will melt and the earth will become an ocean, so let's defend our home together.

1. The heat energy brought by the rise in temperature will provide huge kinetic energy to the air and the ocean, resulting in the formation of large-scale or even super-large typhoons, hurricanes, tsunamis and other disasters.

2. Grain production is reduced.

3. The sea level is rising and freshwater resources are scarce.

4. The rise in temperature has caused the extinction of organisms and the gradual breakage of the food chain in nature.

Extended Materials. 1. The heat energy brought by the rise in temperature will provide huge kinetic energy to the air and the ocean, resulting in the formation of large-scale or even super-large typhoons, hurricanes, tsunamis and other disasters.

Every year, more and more disasters are being struck and faced, and the number of lives and money lost is increasing and becoming more and more unacceptable. Disasters such as typhoons and tsunamis not only directly damage buildings and threaten human life, but also bring secondary disasters, especially the large rainfall caused by disasters such as typhoons and hurricanes, which will lead to mudslides and landslides, which seriously threaten traffic safety and residents' lives.

2. Grain production is reduced.

Rising temperatures absorb water not only directly from the ocean, but also from the land, causing widespread drought in inland areas, reducing food production and feed production. Food and meat products will be scarce, a direct threat to national stability. Panic and fighting over food will no longer be the only thing that happens in backward villages.

3. The sea level is rising and freshwater resources are scarce.

The melting of icebergs by rising temperatures is the main source of fresh water we rely on for survival. A large proportion of our groundwater reserves come from iceberg meltwater. When the temperature balance is normal, the iceberg's ice and snow cycle, that is, the iceberg melts in the summer, flows down the mountain, and flows underground, accumulating fresh water in the plain area and acting as a filter.

In winter, the water returns to the mountains in the form of water vapor, and the snow and ice are reaccumulated through a large amount of snowfall, which is also a filtration process. The whole cycle ensures that our fresh water has a stable balance. Today, global warming has caused icebergs to accumulate much less rapidly than they are melting, and some icebergs are no longer accumulating, cutting off local drinking water and causing sea levels to rise.

This will lead to conflicts and wars due to water scarcity.

4. The rise in temperature has caused the extinction of organisms and the gradual breakage of the food chain in nature.

With the gradual advancement of industrialization, atmospheric carbon dioxide emissions have increased, causing the global greenhouse effect. The persistence of global temperatures** has caused significant changes in the climate.

In our region, for example, the number of typhoons has become less and less in a year, but the wind has become stronger and stronger. There is also the sea level, which makes low-lying areas more threatened.

Impacts and harms caused by global warming:

1. Cause sea level to rise.

Global warming is caused by an increase in the amount of greenhouse gases, carbon dioxide and other components in the air, resulting in an increase in the global surface temperature and an increase in the greenhouse effect. When global warming, glaciers will melt, and all the water melted by glaciers will enter the sea, and the sea level will definitely be ** at this time, and many seaside countries and cities are likely to be submerged.

2. There are storms, floods, and droughts.

This warming will certainly lead to a rise in global temperatures, so there will also be some impact on precipitation, with more and more megastorms sweeping over cities, and more hurricanes and tsunamis engulfing inland cities. Because the heat energy brought by the rising temperature will provide huge kinetic energy to the air and the ocean, it will form large and large typhoons and hurricanes, which will pose a great threat to human buildings and life.

In addition, heavy rainfall can also lead to mudslides and landslides in the interior, which seriously affect people's safety and livelihood. When the temperature rises, it will not only draw water from the ocean, but also from the land, so many areas in the interior will have a large area of drought, and the grain production will be reduced, and the feed production will also be reduced, which will directly affect people's lives, and people may fight for food.

3. The food chain will break.

If global warming occurs, the carbon dioxide content in the air will also rise, so the ocean will carbonate and kill many microorganisms in it, and the temperature of the ocean will also rise, and many coral-centered organisms will completely disappear, so there will be a fault in this amount, and a large number of organisms will die and pollute the ocean will also accelerate the death of other organisms, forming a vicious circle.

Scientists have found that the world emits as much as 12 billion tons of carbon dioxide into the sky every year. Carbon dioxide has a peculiar effect, that is, it can absorb a large amount of heat from the surface and lower layers of the atmosphere, and prevent them from being lost into the air, just like the glass of a greenhouse, so scientists use the term "greenhouse effect" to explain the role of carbon dioxide. The higher the amount of carbon dioxide in the atmosphere, the more pronounced the trend towards climate warming.

To make matters worse, the "greenhouse effect" of certain trace gases in the atmosphere is far greater than that of carbon dioxide. These trace gases include methane from the decay of organic matter, exhaust gases from automobiles, and nitrous oxide released from nitrogen fertilizers in the soil.

Although these gases are not present in large quantities, they have a strong ability to absorb heat and amplify the greenhouse effect of carbon dioxide. In addition to this, there is the effect of more and more artificial heat in the city. It is the combination of these factors that our planet is getting "warmer" day by day.

People are constantly cutting down vegetation for money and profit, resulting in an imbalance of atmospheric carbon dioxide (i.e., too much carbon dioxide) so the planet is warming.

With the development of industry, humans are emitting more and more greenhouse gases, such as carbon dioxide, into the atmosphere. These gases are like a thick quilt that prevents the earth's heat from escaping, causing the planet to warm.

Because the earth's biosphere has been destroyed and the atmosphere has suffered, the earth has begun to warm without a "protective umbrella"!

Because we humans emit a lot of harmful gases, disrupting the natural order, we are warming.

There are many theories in the scientific community about the causes of global warming, the main ones are as follows:

1. The Earth's own climate change law.

2. Large amounts of greenhouse gases emitted by human activities.
