“Global warming” refers to the observed phenomenon of a marked rise in average global temperatures since around 1950. One must hasten to note that the question whether the earth is warming is a separate question from why the earth is warming. Most scientists who study global warming believe that it is due to the increasing release of greenhouse gases (which reflect infrared light radiated from the earth back into the atmosphere, which keeps them it from escaping into space) and increase the net amount of heat on the planet.
In the simplest terms, global warming is just what it sounds like: the worldwide rise in surface temperatures. The cause of global warming is what’s called the "greenhouse effect." That’s shorthand for the ability of gases in the atmosphere to slow down the release of heat into space at night. Some gases are better at this than others. Carbon dioxide, methane and nitrous oxide are the top three "greenhouse gases." They are very good at absorbing sunlight and converting that energy into heat – rather like a rock does just sitting in the sun.
Global warming is an increase in the overall temperature of earth atmosphere. Earth 's climate is changing, temperatures are rising, snow and rainfall are shifting, and more extreme climate like heavy rainstorms and high temperatures are already affecting the society and economy. Scientists are confident that many of the observed changes are happening because of the global warming. Warming and climate are changing and increasing every year. The main Cause are by people burning fuels to generate electricity, heat and cool buildings, and power vehicles. Many cause and effects are happening in the world because of the global warming in the whole environment.
Global warming is defined as the process of gradual growth of average annual temperature of the atmosphere, the Earth, and the oceans. Global warming and climate change threaten the very existence of earths inhabitants. In 2006, former senator Al Gore created an amazing award winning documentary on global warming named “An Inconvenient Truth”. Yet there are still skeptics that can 't decide on whether global warming is actually facts or a theory. People need to wake up and realize that this is real, just look around you. The Glaciers are melting, crazy weather patterns are happening, winters are getting shorter and summers are getting hotter. At the rate we are going we are destroying our Earth. Global warming is a man-made disaster that should be recognized all over the globe. This is an ethical crisis that deserves immediate action.
Global warming is the recent and ongoing rise of temperature on a global scale. Over the past century, the Earth's average temperature has risen 1.4°F (Carlowicz, 2010). Global warming is the effect of an excessive amount of greenhouse gases in the atmosphere. Greenhouse gasses trap heat from escaping back into space to keep the Earth from freezing, this is called the Greenhouse Effect. An excessive amount of greenhouse gases in the atmosphere trap too much heat, thus, causing Earth's temperature to rise.
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 the name given to the increase in the earth’s surface temperature. It is caused by the collection of greenhouse gases, carbon
In “ Think Again: Climate change,” Bill Mckibben addresses the climate change catastrophe. The damage has already begun and it may be too late to save the planet. There has been many debates and controversies on climate change, but that is about to change, and scientists have accepted the fact that humans are warming the planet. In 2007, the Arctic Ocean melted more ice than ever before. Again in 2008, more ice was melted and the Arctic is now open water. In addition, other regions will eventually suffer from crop loss and food shortages. Eventually, climate change will force states to start conflicts and wars over resources.
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 the increase of Earth's average surface temperature due to greenhouse gases that collect in the atmosphere, trapping the sun's heat and causing the planet to warm up
Global warming is concerned with an average increase in the temperature of the atmosphere and the increase in the Earth 's surface temperature primarily due to the emission of greenhouse gases from the burning of fossil fuels. As for the processes of global warming, they can occur from a variety of causes. The causes include the things that are concerned with natural and human factors.
Global warming is the heating of the Earth, as the name implies. It is caused by greenhouse gases, like carbon dioxide, water vapor, and methane, that we have released into our atmosphere through burned fossil fuels and other chemicals
What is global warming? Global warming is the increasing of the average temperature near earth’s surface. It is caused mostly by increasing concentrations of greenhouse gases in the atmosphere. (EPA, 2014) Greenhouse gasses are water vapor, carbon dioxide, methane, nitrous oxide, and fluorocarbons. Some greenhouse gases are
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
Global warming is the increase in the Earth's temperature caused by human activities, such as burning coal, oil and natural gas. This releases gases such as: carbon dioxide, methane, and other greenhouse gases into the atmosphere.
