Global warming is the gradual increase of temperature in Earth’s surface, oceans, and atmosphere. Some people may say that global warming is just a theory that has not been proven scientifically; however, I do believe that global warming is happening and that there is strong evidence about this occurrence. Such evidence includes the increase of carbon dioxide, the rising of sea level, the increase of acid in the ocean, and clearly, the changes in global climate. In fact, mostly all sorts of human activities cause these changes. Ninety-seven percent of climate scientists agree that human actions have changed the Earth’s atmosphere in the past two centuries (Climate.nasa.gov).
The warming of Earth’s surface begins with the greenhouse effect, which is the leading cause of global warming. The greenhouse effect is the exchange of incoming and outgoing energy emission that warms the Earth. A great example of this phenomenon given by Marc Lallanila, writer of “What is the Greenhouse Effect?” is when a car parked in a cold, sunny day. The solar radiation that is coming in warms up the inside of the car, but the solar energy that is going out is trapped inside the car’s closed windows. Greenhouse gases are the gases in the atmosphere that absorb radiation, such as water vapor, carbon dioxide, methane, and nitrous oxide. Out of all these greenhouse gases, carbon dioxide is the primary gas produced due to the combustion of fossil fuels from electricity, transportation, and industrial
What is global warming? It is a problem when too much carbon dioxide in the atmosphere, acts as a blanket and traps in heat which then, ultimately warms the planet. During our
Global warming is a gradual increase in the average temperature of the earth's and its oceans and a change that is believed to permanently changing the earth’s climate.
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.
Greenhouse gases keep heat close to the earth’s surface making it liveable for humans and animals. However, global warming is happening largely due to an over-emittance of these gases and fossil fuels (natural oil, gasoline, coal)
Global Warming is a high rise in the usual climate heat on the Earth's surface. People often use the term climate change to refer mainly to the warming observed since the middle 1800's. Scientists guess that Earth's normal surface temperature rose by about 0.76 Celsius degrees or 1.4 Fahrenheit degrees from the middle 1800's to the 2000's. Researchers have also found that most of the temperature rise happened from the middle 1900's to the 2000's. Normal processes have caused Earth's weather to change in the distant past. But scientists have found big evidence that people activities have caused most of the warming since the middle 1900's.
Global warming is the gradual increase in temperature of the earth’s atmosphere. It is mostly caused by the increased levels of carbon dioxide and other pollutants. Recently, global warming has been rising and is negatively affecting people, animals, and the weather. It is negatively affecting people by increasing health problems such as, cancers, and respiratory problems. It’s causing animals to be put on the endangered list, or even extinct the species as a whole. And it’s affecting the weather by causing an increase in storms such as hurricanes, floods, tornadoes, etc. Global warming is a huge problem that people tend to ignore, and needs to be put to an end.
Global Warming is an increase of the average temperature in the earth's atmosphere. According to some scientists, global warming is caused by carbon dioxide and other air pollutants. It is also caused by the greenhouse gasses in the Earth's atmosphere and the absorbing of the the sunlight. Greenhouse gases is a gas that's in the atmosphere that absorbs the radiation within the thermal range. The first person who apparently discovered global warming was Svante Arrhenius, a Swedish scientist. In 1896, he was the first person to claim that fossil fuel combustion may result in enhanced global warming. People think that global warming is real and that the temperature is rising, but I have reasons why it's not real. Overall, that is all about global warming and its
For the past few years Global Warming has been an issue that continues to worry Scientists from all over the world to this day. Global Warming is a gradual increase in the overall temperature of the Earth’s atmosphere generally attributed to the greenhouse effect caused by higher levels of Carbon Dioxide. Many people believe that Global warming is the one thing that is causing ice to melt on Earth.
Global Warming is the increase of Earth's surface temperature due to effect of greenhouse gases, such as CO2 emissions from burning fossil fuels
Global warming is a process of change in weather or climate, which may be caused by human or natural causes. The specific manifestations that we still hear are the phenomenon of global warming, greenhouse effect, and ice melting phenomenon. Today, people
By definition 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. Our global temperature over the last 50 years has increased at its fastest recorded rate. Experts say they see this trend progressing. (NRDC) The earth’s temperature has has increased by about 2.0 degrees Fahrenheit since the 1900’s. In the last 35 years we have experienced the warmest years ever recorded; 16 years out of 17 since 2001. Global warming occurs when carbon dioxide and other air pollutants and greenhouse gases collect in the atmosphere and absorb sunlight while preventing the sun’s solar rays from escaping back out into space.
a) Greenhouse effect is the direct natural result of Sun powering climate on the Earth. Sun’s radiation is passing through the Earth’s atmosphere which in turn causing the Earth’s surface to warm up. As an estimation, about 30% of the solar energy is bouncing back to the space as a results of the Earth’s atmosphere. The other 70% of solar energy is attracted by the Earth’s surface and atmosphere. In order to create a balance, Earth has to reflect this extra amount of energy back to space but, part of this reflection is absorbs by Earth’s atmosphere and will be sent back to Earth. This process is warming up the Earth’s surface and prevents the temperature on the Earth’s surface to drop below zero Celsius degrees. This is called natural Greenhouse effect but, due to various human activities such as deforestations and fuel burning and other factors have exacerbate this natural process of Greenhouse effect in which created the global warming [1]. The primary greenhouse gases are water vapor (H2O): from the water on the Earth’s surface. Carbon Dioxide (CO2): its increase in the atmosphere is due to the fuel burning process. Methane (CH4): its increase in the atmosphere is due to several reasons such as melting permafrost, landfills generate CH4, and when ocean temperature rises causes release of Methane. Nitrous Oxide (N2O): agriculture and soil cultivating cause increase in the amount of N2O in the atmosphere. Chlorofluorocarbon (CFC): released to the earth’s atmosphere
Global warming is the gradual increase in the overall temperature of the Earth’s atmosphere due to Greenhouse gasses. Greenhouse gasses are a product of the Greenhouse effect, a phenomenon in which particular gasses in the atmosphere trap heat and allow only light to escape, much like the mechanism of the glass on a green house. The term was first coined in the 17th century, around the time of the industrial revolution. Scientist began to notice that the earth was getting hotter, and will continue to get hotter as the years pass by, eventually resulting in immense global climate change. Despite evidence of the phenomenon, the topic has been a debate filled with controversy since its existence. There are those who believe that Global warming is a hoax, but unfortunately there is evidence that proves the legitimacy of global warming and it’s affect on climate change.
Global warming is a phrase that has been used in recent history that describes Earth’s surface temperature being warmed. Throughout history, there has been three global warming’s. They occurred in 1850; from about 1860-1880, 1915-1945, and 1975-1978 (see graph). The current warming was thought to have been generated by the discharge by man of carbon dioxide. All three of these periods of warming were divided into a period of universal cooling. The warming/cooling cycles, and their conjoined change in rain patterns are called climate change. Climate change has been happening for the past 11,000 years since the last ice age. Research has recently shown that this abrupt curve is probably a product of what is known as the “heat island effect” rather than be just called global warming. Overall, at its simplest, “climate change”- is simply known as global warming and “climate disruption.” Reason it is called a climatic disruption is because a phenomenon occurs that cause’s weather arrangement and temperatures too change to quickly and unknowingly on a universal scale. Global Warming is an occurrence of increasing average air temperatures close to the Earth’s exterior for over the past two centuries. Since the 20th century, weather scientists have assembled studies of different weather occurrences such as; temperatures, rain, and different kinds of storms. Also studies on the Earth’s ocean currents and the atmosphere’s overall chemical arrangement. This
Global warming, by definition, is an increase in the temperature of the Earth’s atmosphere and oceans. With the rise in modern technology, the average temperature of the Earth’s surface has increased about 1.4 °F; two-thirds of which has arisen since the early 1980’s. Industrialized countries are major contributors to climate change, due in part to their involvement in deforestation and the burning of fossil fuels. These activities lead to an increase in levels of greenhouse gases, which scientists propose is the number one cause of global warming.
