Hi guys, this is my entry into the @Upmewhale climate change Contest. Upmewhale touched on a very important topic that requires a very interesting discussion, if you want to participate in the discussion of this topic you should read the first article first and this is a Link
So
Global warming is originally a natural phenomenon as there is a group of gases in addition to water vapor present in the atmosphere as essential components, and its concentration in the atmosphere is weak as these gases keep the planet at its temperature.

As a result of the increased emission of these gases due to the increased human activities since the beginning of the industrial age, this increased their protective effect in the atmosphere, which led to the occurrence of one of the largest and most dangerous negative environmental phenomena of our time, which was called the phenomenon of climate change, And global warming is a phenomenon very similar to that in greenhouses.
In the glass greenhouse, sunlight enters the heat into the greenhouse, and then the heat does not seep out at the same rate, resulting in a higher temperature within the greenhouse. Harmful gases emitted from the fumes of factories, oil refineries and car exhausts, for example, cause the same phenomenon, causing the earth's warming from the effects of global warming, melting ice at the poles. . Scientists estimate that if it continues, it will flood many coastal cities around the world. Rising global temperatures will also lead to global climate change and desertification of large areas of the earth.

By increasing human activity and accelerating development, the climate changes because human activity affects the composition of the components of the Earth's atmosphere through the accumulation of gases, especially Carbon Dioxide, Methane and Nitrous Oxide, gases known as Greenhouse Gases and have the property of attracting heat and therefore the Its accumulation causes global warming and although the Earth's interaction with changes in the atmosphere and the planet's attempt to modify its climate, the warming of the Earth is clear, the solar energy emitted by the sun shocks the Earth, which absorbs part of it and reverses the other part to spread in the atmosphere and thus Heating the atmosphere above the ground and without this process, the temperature above the ground will be very low, making life impossible, but by increasing the concentration and accumulation of these heat-trapping gases, the heat will increase more than possible, which may cause problems for life above ground.

As scientific reports indicate that the concentration of Carbon Dioxide in the atmosphere has increased by 30%, that the concentration of Methane has doubled and that the concentration of Nitrous Oxide has increased by about 15%, which has increased the warming retention in the Earth's atmosphere. Although Aerosols are air pollutants, they help to reduce the temperature of the atmosphere by reversing the light to the upper atmosphere, but the lifetime of the Aerosols is short and their concentration varies from place to place and therefore their hypothermia is not sufficient to adjust the temperature in the atmosphere layers.

Scientists believe that the use of hydrocarbons and other human activities is the main cause of the increase in greenhouse gases such as carbon dioxide, and although photosynthesis in plants and the decomposition of organic matter release ten times as much carbon dioxide into the atmosphere, All this is in harmony with the ecosystems on earth before the Industrial Revolution and what happened in recent centuries is the increase in co2 production from human activities, burning energy to run cars and trailers, heating houses, workplaces and the operation of various factories is responsible for 80% of the increase in CO2. The increase in methane and nitrous oxide is due to increased desertification, landfills, various industries, mining and some other gases such as Chlorine, Fluorocarbons and Hydrofluorocarbons, which are produced due to the Foam industry, air conditioning, refrigeration and freezing, and as a result, The temperature above ground is increasing.
Over the past century, the temperature has increased, and this expected increase will increase evaporation speed, reduce the earth's humidity and increase arctic ice melt, as well as ice floating over the Arctic Ocean, causing sea level rise and may flood part of the land. It refers it to a part of the sea, where many people lose their shelters, food sources and measurements of sea level rise, indicating that sea level has risen by about 1,520 cm over the past century.
All this is due to human intervention and unregulated activity that strain ecosystems, which may affect forests, various crops, water sources and threaten human health, wildlife, marine and other ecosystems, while in the past, when life was primitive, the temperature above the Earth is determined by quantity. Solar energy falling on the ground, the amount of sunlight reflected from the Earth to the atmosphere and the amount of atmospheric confinement of heat. Today and in the future, it will determine the temperature of the Earth, mainly how much man and his activities will increase the production of heat-trapping gases, greenhouse gases and release them into the atmosphere.
Thus, global warming is today considered one of the worst threats to the sustainability of the environment above the Earth and thus life above it humans and other neighborhoods and environmental regulations, and since the most advanced countries, the industrialized countries, are the most harmful to the environment and the most causing the rise in temperature above the earth, Its duty is to start by reducing the use of hydrocarbons and follow the foundations of agriculture and clean industry and preserve forests and ecosystems that absorb carbon from the atmosphere and everyone must apply the Agreement on Climate Change issued (UNFCCC) in 1992, which is centered on reducing the production of greenhouse gases. The Kyoto Protocol was also signed, which obliged the industrialized countries to reach specific targets in order to make the agreement and protocol a success.

Global warming and overheating above the Earth have a major impact on life on our planet and may make it impossible. The effect of high temperature on humans is divided into a direct effect may lead to death and many diseases are increasingly prevalent with high temperature, and in general indirectly high temperature strained the circulatory system and respiratory system in humans and high temperature increases ozone gas which is useful in The upper atmosphere where life is protected from UV radiation but in the lower atmosphere polluted the risk of spoiling the human lung and increases the problems of patients with asthma and other lung diseases and statistical information today reports that the mortality rate increases on the days when the temperature rises When the temperature rises throughout the year as well as the warming of the earth may increase the communicable diseases transmitted by mosquitoes and other insects malaria, yellow fever and meningitis as well as cholera diseases and food poisoning diseases such as Salmonella and Shigellae as well as increased temperature increases The incidence of so-called sunstroke. It causes the loss of much fish, and fish diseases and other natural resources are increasing and are the source of life and food for the human species.
