Greenhouse effect
The so-called greenhouse effect is short wave solar radiation through the atmosphere into the ground, and warming the ground after the length of radiation being released in the atmosphere by absorbing carbon dioxide and other substances, thereby creating the effect of atmospheric warming.

in sea levels worldwide
Scientists predict an increase in sea levels worldwide due to the melting of two massive ice sheets in Antarctica and Greenland, especially on the East coast of the US. However, many nations around the world will experience the effects of rising sea , which could displace millions of people.
Increase in usage of chemical fertilizers on croplands
Carbon dioxide emissions from fossil fuel burning power plants
Every day, more electric gadgets flood the market, and without widespread alternative energy sources, we are highly dependent on burning coal for our personal and commercial electrical supply.
Deforestation , especially tropical forests for wood, pulp, and farmland
The use of forests for fuel is one cause of deforestation. Forests remove and store carbon dioxide from the atmosphere, and this deforestation releases large amounts of carbon, as well as reducing the amount of carbon capture on the planet.

要点二
Metal emissions
Investing in technologies and practices to reduce metal emissions from agriculture, landfills, and natural gas production
要点三
Nitrous oxide emissions
Glacier melting
Glaciers are retreating at an increasing rate, losing mass and shrinking in size This is due to warming temperatures, which is due to ice to melt and glaciers to receive
exacerbation of the greenhouse effect and ultimately causing global warming.
The impact of global warming
Global warming has a wide-ranging impact on natural ecosystems and human society.
Ecosystems are also experiencing shifts in specifications composition, range, and background This can lead to a loss of biodiversity and disrupt ecological balance The loss of specifications and ecosystems has negative implications for human well being and sustainable development

The Prall Global Warming
The figure shows the combined land-surface air and sea surface temperatures (degrees Centigrade) 1861 to 1998, relative to the average temperature between 1961 and 1990.The mean global surface temperature has increased by about 0.3 to 0.6°C since the late 19th century and by about 0.2 to 0.3°C over the last 40 years, which is the period with most reliable data. Recent years have been among the warmest since 1860 the period for which instrumental records are available. Warming is evident in both sea surface and land-based surface air temperatures. Urbanization in general and desertification could have contributed only a small fraction of the overall global warming, although urbanization may have been an important influence in some regions. Indirect indicators such as borehole temperatures and glacier shrinkage provide independent support for the observed warming. It should also be noted that the warming has not been globally uniform. The recent warming has been greatest between 40°N and 70°N latitude, though some areas such as the North Atlantic Ocean have cooled in the recent decades.

Mechanism of green house gases: Greenhouse gases are those gases that trap the heat in the atmosphere of the earth. The gases that are responsible for anthropogenic global warming overlap with the gases that make the earth warm in order to support life. The important green house gases include carbon dioxide, methane, water vapor and nitrous oxide. These gases may be needed fro sustenance of life. However, an excess of the gas can cause the temperatures to increase. When the rays of the sun enter the atmosphere of the earth, they reach the ground, oceans, and ice caps of the polar regions. Most of these rays are absorbed as heat, light, and energy. Some of the rays are reflected back to the atmosphere. Some of it escapes into space, while a small percentage gets trapped by the greenhouse gases. The amount of green house gases is directly proportional to the heat present in the atmosphere. Greenhouse gases such as nitrous oxide and nitrogen are processed by the atmosphere. However, this process is slow. As long as these gases are present in the atmosphere, they will trap heat.

Global warming due to Human activities: There is a plethora of human activities that cause the release of greenhouse gases. Factories, electricity production, air travel, large-scale farming, and running of vehicles all depend on fossil fuels for their energy. The burning of coal, gasoline, and oil releases large amounts of carbon dioxide in the atmosphere. Nitrous oxide is the byproduct of farming. This gas may be present in small quantities but beats carbon dioxide in the trapping of heat. Industrial activity releases chemicals and toxins which cause water vapor to develop. This contributes to acid rain and smog. Besides the climate and wildlife species, humans are also affected byanthropogenic global warming. Pollution causes respiratory diseases, asthma, and potential health problems.

Anthropogenic Global Warming: The Facts
The formation of greenhouse gases by humans has caused an environmental problem known as anthropogenic global warming. This causes massive climate change. Anthropological global warming is also known as global climate change or, simply, global warming. The term refers to a rise in the earth’s temperature. The temperature of the earth is going to increase by some degrees due to anthropogenic global warming. This temperature change can have disastrous effects. Anthropogenic global warming is the result of burning fossil fuels that create the greenhouse effect.
