  • Essay / Global warming: the biggest challenge facing our planet

    Global warming is the biggest challenge facing our planet. These are current and widely discussed factors. This has a considerable impact on our planet's biodiversity and climate. Global warming constitutes a warning for living beings on this planet. The global average temperature has increased over the past 100 years. According to scientists, most of the increase in temperatures since 1950 is due to increased concentrations of greenhouse gases produced by human activity. Scientists agree that the planet's temperature has increased by 0.5 degrees Celsius since 1900 and will continue to rise. Say no to plagiarism.

Global warming refers to any warming of surface air over the past two centuries that can be traced. Global warming is linked to the general phenomenon of climate change, which refers to changes in the set of factors that define the climate. In addition to changes in air temperature, climate change also involves changes in winds, oceans, and other measures of climate. Climate change can be seen as the combination of many forces occurring over different time scales. Since human civilization, climate change has involved a human-made element and this element has become more important during the industrial period of the last two centuries. The imbalance we have created between our life and the earth is showing signs of disaster in the form of floods, landslides and drought. If the imbalance continues to increase, it will one day pose a question mark on the existence of this planet. Carbon dioxide is an important constituent of the environment and causes a warming effect at the surface. Global warming is the current increase in the temperature of the Earth's surface, both land and water, as well as its atmosphere. When Earth experienced temperature increases, it was the result of natural causes, but today it is due to the buildup of greenhouse gases in the atmosphere produced by human activities. Scientific research has shown with more than 90% certainty that this increase in global temperatures is due to greenhouse gases produced by human activities such as deforestation and the burning of fossil fuels. These results are recognized by the national academies of sciences of all major industrialized countries. Global warming affects many regions of the world. This accelerates the melting of ice sheets and permafrost, leading to a rise in average sea level. This changes weather conditions in different places and makes some regions drier with more intense dry spells. These changes have affected both nature and human society and will continue to have increasingly serious effects if greenhouse gas emissions continue to grow at the same rate. like today. The natural greenhouse effect keeps Earth's temperature at a safe level, allowing humans and other life forms to exist. However, since the introduction of industry, human activities have greatly increased the greenhouse effect, causing the Earth's average temperature to increase. This creates global warmingwhich we are witnessing today. To put this increase in perspective, it is important to understand that during the last ice age, a period of massive climate change, the average temperature change around the globe was 5°C. The Earth's temperature is determined by the Sun. just 29% of sunlight is reflected back into space because of surfaces like clouds or ice. The remaining 71% is mostly captured by the ocean and land, and the rest is absorbed by the environment. The absorbed solar energy heats our planet. When rocks, air or seas heat up, they radiate thermal energy. This energy spreads through the atmosphere where much of it is absorbed by water vapor and greenhouse gases like methane. When they absorb radiant energy from a surface, the water and greenhouse gas molecules turn into a small radiator like the bricks of a fireplace, radiating heat even after the fire has gone out. They radiate in all directions. The energy radiating toward Earth heats both the lower atmosphere and the surface, increasing the heat they receive from sunlight. This absorption and radiation of heat by the atmosphere as well as the natural greenhouse effect are beneficial to life on Earth. If there were no greenhouse effect, the average temperature on Earth's surface would be very cold instead of as comfortable as it is today. Temperatures will certainly rise. It seems the temperature is rising faster than ever. Human activities such as increasing pollution and industrialization are considered to be the factors responsible for increasing global warming. The evidence that humans are causing global warming is strong, but the question of how to fix it remains controversial. Economics and politics are important factors in planning for the future. Even if we stopped emitting greenhouse gases today, the Earth would still warm to another degree. SO. But what we do from today will make a big difference. Governments and NGOs are already working hard to reduce greenhouse gases and everyone can contribute to this noble cause of humanity. Global warming may lead us to immense water and food shortages. This has a potentially fatal impact on wildlife. Droughts, forest fires, extinction of endangered species, storms are some of the effects of global warming. Emissions such as CO2, nitrous oxide and other greenhouse gases will remain in the environment for many years, making it impossible to eliminate global warming for several decades. Global warming, which causes major climate changes, has shown its implications in the form of forest fires or heat waves. A common goal is too stable greenhouse gas concentrations around 460-560 ppm, about twice pre-industrial levels. It is at this point that many believe that the most damaging climate effects from global warming can be avoided. We had to reduce greenhouse gas emissions by 40 to 70 percent of what they are on track to be in the next century to reach this level. Current concentrations are around 378 ppm, meaning there isn't much time to waste. The global warming hypothesis states that increasing atmospheric CO2 will strengthen the greenhouse effect, which is important in increasing global temperatures and will have destructive consequences. An admirer of this hypothesis maintains thatGround-based calculations show that the global average temperature is 0.51°C higher than a century ago and the air temperature above the ocean is also determined. Computer models predict a global temperature increase of up to 8°C by 2100, resulting from a proven increase in atmospheric carbon. It is also hypothesized that this would have different effects, including rising sea levels, increased disease and famine in many areas, extinction of plant and animal species, and more adverse weather conditions. Many went on to argue that we must take strong action to avoid the predicted consequences of catastrophic temperature increases. They project stark limits on energy consumption. To achieve the study of global warming, this research uses a qualitative approach that explores and emphasizes meanings and experiences. It is also considered descriptive research because reasonable knowledge has been gained, but more detailed information still needs to be processed. Therefore, structured interviews, focus groups and questionnaires are more likely to be used for this purpose. This research was carried out using survey information as well as some articles regarding climate change. We carried out this research by analyzing the speeches of world leaders on this issue. Media reports on global warming have also taken this into account. A case study on global warming and a national approach were useful. GHGs will remain in the environment for many years. The consequences that global warming causes on earth are extremely serious. Various consequences will occur in the future if global warming continues. This includes economic consequences and more hurricanes. Additionally, the spread of disease and earthquakes can be a problem. The first effect is the melting of the polar ice caps. As the temperature increases, the ice at the North Pole will melt. Once the ice melts, the effect will increase on sea level, because the part that melts becomes the oceans. It affects low-lying areas such as the Netherlands. The Netherlands will then be surrounded by water. It won't happen that quickly, but sea levels will continue to rise. The second effect is the loss of species habitat. Species that include polar bears and tropical frogs will become extinct due to climate change. Various birds will migrate to certain places because animals are not like humans. They cannot adopt a habitat that changes their lifestyle and temperature. Another effect is that more hurricanes will occur and their economic consequences will also have an impact. The hurricane causes damage to houses and the government has to spend billions of rupees on damages and people demand places to rest or are killed. When a disaster strikes, many people die and illnesses occur. Illnesses are serious because they can spread quickly to other people and more people will get the illness. The disease is usually more severe due to different climatic conditions. RESULTS Global warming affects the Earth's climate as well as the physical atmosphere. The most visible effects of global warming are seen in the Arctic, where glaciers, permafrost and sea ice are melting rapidly, which can lead to sea level rise. Global warming affects the atmosphere.
