Global Warming
What is it?
Global warming is when the average global temperature increases. The global temperature has increased to the fastest ever recorded rate in history in the past half century. Climate changes like global warming is the result of human practices like the emission of Greenhouse gases. Global warming leads to rising temperatures of the ground and oceans causing melting of polar ice caps, a rise in sea levels as well as unnatural patterns of precipitation such as flash floods, excessive snow or desertification.
Why does it occur?
The main cause of global warming is due to greenhouse gases as well as other air pollutants that collect in the atmosphere. Sunlight and solar radiation that should have bounced off the earth’s surface is absorbed by these pollutants. If the pollutants weren’t in the atmosphere, radiation would escape into space. Pollutants are known to last as long as centuries within the atmosphere, they trap heat and in turn cause the planet to overheat. This is the greenhouse effect; the greenhouse effect is the cause of global warming.
How do you know Global warming occurs?
There are 10 main indicators of Global Warming, these indicators are; land surface temperature, sea surface temperature, air temperature over the oceans, lower troposphere temperature, ocean heat content, sea level, humidity, glaciers, the Northern Hemisphere snow cover and sea ice. Temperatures (Land, sea, air, lower troposphere) have all rose to the highest recorded in history in the last decade. This has caused the humidity to increase as well as the ocean heat content, because of the increase in humidity, glaciers and snow covers have been melting and due to ocean heat content sea ice levels have decreased.
Who it affects and negative effects.
Global warming affects everyone. It affects our environment, the place we call home, and in turn it affects us. Humans can’t function without the environment, we rely on the environment for food, for water, and as our home.
An increase in temperature can cause serious issues in agriculture, there has been a struggle to maintain the specific conditions crops need in order to survive. A study that was published by Stanford University showed that global wheat
Global warming refers to the rise in temperature in the Earth's atmosphere and oceans. Each year the temperature of the Earth increases gradually with an insignificant amount; however, with pollution produced by humans, the rate has increased even more compared to pre-industrial levels. According to NOAA, "Global surface temperature in 2016 was the warmest since official records began in 1880. It was the third year in a row to set a new heat record, and the fifth time the record has been broken since the start of the 21st century.” The earth is getting warmer every day and is starting to become a real problem, especially when it is approaching the threshold. The rise in temperature is so rapid that it could influence and change the composition of the world's population. In fact, the consequences of global warming are unnoticed in our daily lives because they are affecting us slowly. The rising average temperature of Earth is changing our lives for little things. There is much evidence that the Earth is warming as a result of the increased concentration of greenhouse gases in the atmosphere. Perhaps the most notable signs of global warming are the natural catastrophes like hurricanes and winter storms. The effects of global warming are different all over the world, and they affect people's lives differently. People should be concerned about global warming and its effects because we only have one planet where we can
Global warming is the rise of average temperature in the earth’s atmosphere since the late 19th century. Since the beginning of the early 20th century, the earths mean surface temperature had increased by around 0.8 degrees. Warming of the climate system had become more obvious and scientists are 90% sure that the main cause of the increase in temperature in due to the increasing concentrations of greenhouse gases due to human activities such as deforestation and burning of fossil fuels.
Global warming is a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants. (What is global warming, google.com). Scientists have stated that the rise in average temperatures worldwide since the late 1800s. Earth's temperature has gone up by 1.4 degrees over the past century, according to the Environmental Protection Agency. Temperatures are to rise another 2 to 11.5 degrees over the next 100 years (what is global warming, livescience.com). Human are one of the main causes for global warming, all of the cars, factors and electricity production they have created. They have also created Greenhouse which gases
Global Warming is an increase in the average temperature around the world. Scientists have been able to trace the global climate and concluded that over the last ten thousand years, the climate of the earth has been relatively constant. In the twentieth century, the global temperature increased 0.740°C. The change in the warming, and cooling, of average global temperatures cause climate change, a change related to climate patterns such as temperatures, rainfall, wind and humidity. This flux in temperature is affected by multiple factors making it hard to determine the true source of problem. Evidence supports that the earth's warming is natural; however, some data indicates that the warming trend has increased due to human activity.
Global warming is an increase in the temperature of the earth's weather. Global warming is also known as the green house effect. Global warming is a very serious world issue. Most humans are trying to do as much as they can to help stop global warming. Global warming has caused many problems to the earth in addition to the humans that live here on the earth. A problem caused by global warming is very hot summers. Some summers have had days that the temperature had reached 30*C. Another Problem that global warming has caused is the melting of polar ice caps. Global warming caused the polar ice caps to melt which will cause the ice to break free as well as melt in the sea, sea levels all over the world will rise. Lastly,
Evidence that Global warming is happening - Major warming and cooling events have happened in the past due to Earth's orbital patterns. In the diagram below, are the three orbital properties of Earth. If all three of the Earth's orbital properties lineup and result in us (the planet) being at maximum distance from the sun (but still in our orbit)… Rapid cooling of the planet will occur. Same goes for the opposite, if all three
Global warming is the escalation of Earth’s average temperatures due to the effect of greenhouse gases. Such as carbon dioxide emissions from burning fossils fuels and the disforestation of our forest and jungles, which trap the heat that would eventually escape from earth back to space. This is a method of greenhouse effect. Global climate change is already beginning to transmute the presence of life on earth. Also, climate change is transforming the landscape, the rising seas, stronger storms, increased risk of floods and droughts, higher temperatures, more heat-related illnesses with in humans and the economy.
Global warming is a gradual increase in the overall temperature of the earth’s atmosphere that is caused by increased levels of carbon dioxide and other pollutants. There are many explanations as to why this happened. Most reasons will relate back to human activities.
What exactly is global warming? According to the Oxford Dictionary, global warming is “a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants.” There are many factors that cause global warming. The main cause of global warming would be the greenhouse effect. The greenhouse effect is “the process in which long wave radiation (infrared) emitted by the earth's surface is absorbed by atmospheric gases only to cause further emission of infrared radiation back to the earth, warming its surface.”(New World Encyclopedia). The noticeable sun powered radiation generally warms the surface, not the environment, though the majority of the infrared radiation getting away to space is transmitted from the upper air, not the surface. "Thirty percent of the solar flux is absorbed by the earth’s surface and transferred to the atmosphere in the form
Global warming is among the major problems that human face today. Today it is among the most widely discussed subjects, with its effects on biodiversity and the climatic state of the environment. Various trends have provided proof that global warming has led to melting of ice cap which in turn leads to increase in sea levels as well as contributing to significant climate changes. In summary global warming is a danger that living things face on earth. During the previous
Global warming is a big problem. An increase in water temperature can result in the death of many aquatic organisms and disrupt many marine habitats. Global warming is a process where the average global temperature increases due to the greenhouse effect. The burning of fossil fuel releases greenhouse gases, such as carbon dioxide, into the atmosphere. This causes heat from the sun to get ‘trapped’ in the Earth’s atmosphere and consequently the global temperature rises.
Global warming is the gradual increase in Earth’s average surface temperature. Between 1906 and 2005, Earth’s temperature rose from 0.6 to 0.9 degrees Fahrenheit, and the rate of increase in temperature has doubled over the past 50 years. Throughout history, climate has changed due to the amount of sunlight absorbed as the planet rotates. However, over the past century, humanity has been another force that has started to influence Earth’s climate. Although there are many causes that severely affect Earth’s temperature, many solutions can help better our environment.
By definition, global warming is the increase in the Earth’s average surface temperature as a result of rising levels of greenhouse gases (Dunbar). In the recent years, studies have been devoted to finding causes for a slowdown in global surface temperatures. However, there has been no slow down. An article in journal of Science disproves this theory. Scientist have concluded that the estimate for the rate of global warming during the first fifteen years of the twenty-first century will be equal, if not greater warming effect as the last half of the twentieth century. Thus, indicating that the proposed slowdown of global warming is false (Karl et. al).
Global warming is a phenomenon that shows an average of the increase in temperature of the Earth's atmosphere and oceans. In the last decades, this phenomenon has caused a lot of damage in several places in the world, those being reflected as floods, fires, and change in the temperature around the world. Therefore it is important to raise awareness to reduce the damage caused, which is mainly due to industrialization and a large number of factories that are around the world, and made by the human hand. Global warming is an increase in the average temperature of the atmosphere over time, which has risen mainly by carbon dioxide emissions, which takes part in the increase of the greenhouse effect. It is a natural phenomenon caused by a series of gases that are in the atmosphere, causing some of the heat of the sun to be trapped in the atmosphere, giving cause to high temperatures to occur.
Global Warming is an important ecological issue and has many negative effects upon our environment. Global Warming, or what has been called the Greenhouse effect, is the result of a fourfold ecological process. 1-Sunlight radiates from the sun, through space, to Earth’s atmosphere. 2- The sunlight enters the atmosphere and hits Earth. Some of it turns into heat energy in the form of infrared light. The heat gets absorbed by surrounding air and land, which in turn makes it warm. 3- Infrared rays, that are remitted into the atmosphere are trapped by greenhouse gases. 4- The gas then absorbs the light and is remitted back to the Earth’s surface and warms it even more. Left on it's own this natural process keeps our
