The impact of global warming on humanity and what is the impact of global warming on humanity?

What are the effects of global warming on humans?

Global warming. Harm to humans.

1.Rising temperatures provide kinetic energy to the air and the ocean, forming super-sized typhoons, tsunamis and other disasters. Every year, more and more disasters are faced, and typhoons and tsunamis can also damage buildings, threaten human life, and bring mudslides.

and landslides, which pose huge hidden dangers to human beings.

2.Rising temperatures will also lead to significant reductions in food and feed production in the interior, leading to food and meat shortages.

3.As the temperature rises, the melting icebergs do not accumulate as fast as they melt, so the icebergs do not accumulate, and we have no fresh water to drink.

4.Rising temperatures have made the natural food chain.

Gradually breaking. 5.Carbon dioxide in the atmosphere.

will also lead to an increase in carbon dioxide levels in the oceans, which will carbonate the oceans and kill microorganisms, so that the marine food chain will be broken, and marine life will die in large numbers.

6.Rising temperatures also make a lot of invertebrates.

Awakening from hibernation, these insects then miss the opportunity to hunt and die in large numbers, eating large quantities of forests and crops due to the insects waking up early.

7.At the same time, the rise in temperature will also affect the human body's functions, the probability of illness will be higher and higher, and various physiological diseases will also spread rapidly.

8.As the temperature rises, glaciers melt and sea levels rise, causing coastal tidal wetlands and mangrove forests.

and the loss of ecological groups such as coral reefs, coastal erosion, seawater intrusion into coastal underground freshwater layers, and salinization of coastal land, etc., resulting in the imbalance of the natural ecological environment of coasts, estuaries, and bays, and bringing disasters to the ecological environment of the coastal zone.

9.The area of water has increased. Water is also evaporating more, the rainy season is longer, and floods are becoming more frequent. Increased exposure to flooding, increased severity and severity of storm impacts, and shortened dam lifespans.

The 1999-2019 global temperature change poor countries were vulnerable before the climate warmed because they were already too weak. The slightest negative impact from the outside world is a heavy burden. For example, a warming climate will make the middle and low latitudes of Africa arid due to intense evaporation.

Researchers at the University of Leeds in the United Kingdom, among others, believe that a warming climate will reduce banana and maize yields by 30 percent and beans by 60 percent in sub-Saharan Africa, both staple foods or important incomes**. In the next 30 years, sub-Saharan Africa's food**, farmland and water resources will be more threatened by climate change. A warming climate will also lead to an increase in extreme weather.

Take typhoons, for example. Developed countries can afford to build safer and stronger homes (e.g., in developed countries such as Japan and New Zealand, which can withstand Level 9**), have better infrastructure and rescue reserves such as search and rescue teams, emergency equipment, hospitals, etc., and have enough savings to cope with disaster reconstruction. But poor countries do not have the capacity to withstand natural disasters.

For example, in March 2019, Hurricane Idai killed more than 1,000 people in Mozambique. In the hardest-hit port of Beira, almost all communication lines have been destroyed, hospitals have been badly damaged, and foreign aid has to be relied upon. Regions such as Bangladesh and Palau lose 2% of their GDP each typhoon season to fight typhoons and provide relief to victims, a figure that could expand to 5% in a more volatile global climate.

Global warming has caused a large number of glaciers to melt gradually, causing sea levels to rise, threatening the lives of people in coastal areas; The cold season will be shortened, and the warm and hot seasons will be extended; This has led to an increase in extreme weather such as droughts and typhoons; This leads to an increase in the concentration of ozone in the low air, which can damage people's lung tissues and cause some lung diseases such as asthma.

Global climate warming also has an impact on people's bodies, mainly in the rise in temperature, which has an impact on the climate, which will cause the melting of snow-capped mountains and the rise of sea levels.

Sea level rise, glacier melting, extreme weather increases, and the cold season is shortened, affecting human health and damaging the ecological environment. Humanity in the Industrial Revolution.

Since then, humans have used a large number of fossil fuels such as coal and oil, thus emitting a large amount of carbon dioxide into the atmosphere.

Humans emit more than 40 billion tonnes of carbon dioxide each year.

The destruction of the earth's vegetation by humans, especially the destruction of a large number of forests that can absorb carbon dioxide through photosynthesis, has reduced the absorption of carbon dioxide by vegetation.

With the massive emission of greenhouse gases, the temperature has risen, which has threatened people's homes. Global warming.

The gradual melting of large quantities of glaciers has caused sea levels to rise, threatening coastal areas. Due to rising global temperatures, the cold season will be shortened and the warm and hot seasons will be extended. Global warming.

This will lead to an increase in extreme weather such as droughts and typhoons. Global warming leads to an increase in low-altitude ozone concentrations, which can damage a person's lung tissue and trigger asthma.

and some other lung diseases. Global warming affects and destroys the biological and food chains, and will bring more serious natural consequences. In order to make our home better in the future, we should minimize greenhouse gas emissions, travel green, and protect our ecological environment.

Global warming is a rapid climate change for the earth, but it is a slow climate change for human beings, which is gradually accumulated year after year, and will have many profound effects imperceptibly, and may eventually reach qualitative change after quantitative change. Specifically, the impact of global warming can be summarized in the following five aspects: First, global warming itself is a change in climate resource conditions, which will lead to the increase or decrease of climate factor temperature and precipitation, and change the spatial distribution pattern of water and heat resources.

Global warming has exacerbated the occurrence of natural disasters, such as the 2% to 4% increase in the frequency of heavy rainfall in the mid- and high-latitude regions of the Northern Hemisphere in the second half of the 20th century, and the occurrence of extreme weather phenomena such as El Niño due to global warming.

La Niña, cold waves, droughts and other disasters are frequent.

1. The Arctic ice sheet is melting.

As the seasons change, the ice sheet melts and solidifies. But the disappearance of permafrost is a much longer process. The coastal lands of the polar regions are under threat due to a number of factors.

Rising global temperatures have melted mud-rich permafrost sediments, increased the intensity of ocean storms, washed sediments with waves, and caused floods that have eroded large swaths of land. In **, the vanishing coastline of the Pofort Sea in Alaska shows the effects of climate change.

2. Chernobyl nuclear power plant**, leakage.

The largest human-caused nuclear catastrophe occurred in 1968 in Chernobyl, Ukraine. At about one o'clock in the morning on April 26, a reactor occurred**. Along with the flames and nuclear leakage, 50 people died on the spot, thousands of people developed cancer, and all died after that.

The real catastrophe is unfolding in Chernobyl. The radiation spread far away, polluting the air, food, and groundwater, affecting locals for decades. Now the number of nuclear power plants in the United States is more than 60, and many have multiple reactors.

3. The Brazilian Amazon rainforest has been severely damaged by human deforestation.

Deforestation of the Brazilian Amazon rainforest has risen at an alarming rate over the past decade. Ranchers, ranchers and loggers destroy 10,088 square miles of rainforest each year, which is the size of Hampshire, England. More than 50% of the world's wildlife and 40% of the world's oxygen come from the Amazon.

4. Developed countries carry out industrial mining in developing countries.

Both developed and developing countries rely on the mining of rare metals to boost their economies. But there can be a significant environmental cost. People dig pits above ground to extract the minerals they need, and soil erosion affects the surface and disrupts the ecological balance.

The ecology of the mining area is difficult to recover. For example, India's Sukendar Valley, which has 95% of India's chromite reserves, has turned it into one of the most polluted places in the world.

5. Overfishing.

The variety of fish that humans have eaten over the past two decades has actually declined. Rising demand and declining demand have led to the complete extinction of bluefin tuna and cod in the North Atlantic and Mediterranean.

The document documenting overfishing in 2009 was called "The End". In addition to the regret that fish can no longer be cooked, the rupture of the chain of important marine life will affect the survival of human beings. The health and continued development of the ocean is a major driver of the world's climate, and it is the foundation of both marine and terrestrial food**.

Sea level rises.

for agricultural production; Crop yields will decrease at lower latitudes, while crop yields are likely to increase at higher latitudes.

It will affect the whole water cycle, which may increase evaporation, change the regional precipitation and precipitation distribution pattern, increase the occurrence of extreme precipitation events, and lead to the increase in the frequency and intensity of drought and flood disasters, as well as changes in surface runoff. With the decrease of runoff and the increase of evaporation, global warming will exacerbate the instability of water resources and the contradiction between supply and demand.

Summary. Hello dear, for you to inquire: mainly including the following aspects:

Climate change: Global warming leads to abnormal climate, rising temperatures, and frequent occurrence of extreme climate events, such as droughts, floods, storms, etc., which bring serious disasters and losses to human beings. Sea level rises.

Global warming is caused by a combination of factors, the main of which include: Greenhouse gas emissions: A large amount of greenhouse gases such as carbon dioxide and methane are one of the main causes of global warming.

These gases absorb the heat reflected off the Earth's surface and prevent it from being lost into the atmosphere, causing the Earth's temperature to rise. Industrialization, Urbanization, and the Use of Transportation: With the growth of the population and the development of the economy, the use of industrialization, urbanization and transportation has increased dramatically, causing a large amount of greenhouse gas emissions and exacerbating global warming.

Impacts of human activities: Human activities such as deforestation, grassland reclamation, and the use of fossil fuels can lead to the emission of greenhouse gases and have a negative impact on global warming. Natural Factors:

Natural factors such as solar radiation, volcanic eruptions, etc., can also have a certain impact on climate change.

The main causes of global warming are rising sea levels, melting glaciers, heat waves, storms and floods, and droughts.

1. Sea level rise.

The presence of hot weather on the planet does not mean that Miami's lifestyle will be on par with that of Africa, but it does lead to rising sea levels. High temperatures cause icebergs to melt, and sea ice and polar ice sheets are melting, increasing the amount of water in the oceans, which is causing sea levels to rise.

2. Melting glaciers.

Observing whether a glacier is melting does not require special equipment. The permafrost that used to cover the surface of the tundra has thawed due to the increase in surface temperature, and vegetation now grows on it. Montana's National Glacier Park has lost much of its beauty due to rising surface temperatures.

3. Heat waves.

In 2003, a deadly heat wave that swept across Europe killed about 10,000 people, which may have been a harbinger of the trend of extreme heat that scientists began tracking in the early 20th century. Heat waves not only inhibit some of the body's functions, but can also kill people. In the last 50 to 100 years, extreme heat waves have occurred two to four times more frequently than usual.

According to **, in the next 40 years, there will be more than 100 times higher.

4. Storms and floods.

Experts use climate models** to show that rising global temperatures will have a side effect on precipitation. In just 30 years, the frequency of severe Category 4 to 5 hurricanes has nearly doubled, and warm waters have increased the likelihood of severe storms.

5. Drought. While some parts of the world are hit by storms and floods, others are threatened by drought. As the climate warms, experts estimate that drought conditions could increase by at least 66 percent, shrinking water supplies and leading to a decline in the quality of crop production.

This puts global food production and supply at risk, and people are increasingly at risk of starvation.
