Global warming, by definition, is the increasing average temperature on a global scale. Many scientists agree that the primary cause of this phenomenon is the collection of various “greenhouse gases” and carbon dioxide in the atmosphere. These gases are said to come from the burning of fossil fuels in order to produce electricity, which has been gradually but greatly increasing since approximately 1750. For the most part, global warming, or climate change, is a universally accepted truth – but for some reason, there is a large resistance to the legitimacy of it. As of the year 2016, carbon dioxide in the atmosphere’s concentration had reached a record high of 400 parts per million. This is the highest it’s been in the last three million years. Possibly coincidentally, that same year had the hottest recorded temperatures of all time, with temperatures at an average of 1.78 Fahrenheit warmer than the average of the twentieth century’s. 2016 was, again, record setting for the third year in a row. Now, the planet's glaciers and polar ice sheets are melting due to this warmer atmosphere. As a result, sea levels are rising notably. With this melting ice, dark water is exposed, which absorbs more sunlight than it did previously as ice, which subsequently triggers a cycle of heating and melting. Alongside the raising temperatures and sea level, comes more extreme weather. Heat waves have become even more frequent worldwide than they ever have been, resulting in an exponential
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 average temperature of the earth's and its oceans and a change that is believed to permanently changing the earth’s climate.
Rising temperatures are causing melting glaciers, which cause rising oceans. Rising oceans will envelop entire coastal cities, killing or displacing millions of people. Our food sources will dwindle; entire species of animals will become extinct as we destroy their homes to rebuild; and as our population skyrockets, an unimaginable number of humans will be left homeless, starving, and sick.
Global warming is one of the most tumultuous topics in today’s society. Some believe it is happening as we speak, while others question its very existence, So, is it real, or is merely a hoax? There is no one answer, but evidence does overwhelmingly support the former. Surely we have all heard this word at one time or another, but few individuals actually know its true definition. Justifiably, however, global warming is not that simply explained. In layman’s terms, it is the dramatic increase in the Earth’s average air and ocean temperature since the 20th century. This increase is primarily attributed to two main culprits: the greenhouse effect and human activity, such as fossil fuel burning. In both cases, carbon dioxide (CO2) is the
Climate change is evident throughout the world and is a major issue. It is no secret that our planet is getting warmer. Global warming is now recognized in the scientific community as a real problem. There are multiple aspects that are causing this issue. Majority of the warming is caused by greenhouse gases. Volcanic eruptions and changes in the intensity of solar radiation have offset the warming partially. It is estimated that average annual temperatures will increase 3.5°F-9.5°F by the century’s end.
Global warming has become a world wide issue and an issue that is causing great controversy. It is an increase in the earth's atmospheric and oceanic temperatures widely predicted to occur due to an increase in the greenhouse effect resulting especially from pollution (Dictionary). Global warming is a natural process, but because of increase in certain activities this process is taking a faster and more dangerous route creating global problems. Global warming was first theorized in 1894 by Jean Baptiste Joseph Fourier a French mathematician, who noticed the earth was gradually increasing in temperature. He came to the conclusion that the earth’s atmosphere was trapping solar radiation caused by the sun and reflecting this radiation back to
One impact of climate change is rising seas levels. Sea levels will rise because when the Earth heats up, the warmer water expands shrinking shorelines; a process called thermal expansion. In addition, when glaciers melt the problem is twofold, the glaciers will release fresh water into the oceans, submerging low-lying land, threatening dense coastal populations, eroding shorelines, desecrating property, and exterminating ecosystems
Global warming, or what is now called climate change, is caused by the sunlight coming through the Earth’s atmosphere, containing greenhouse gasses, and becoming cemented between the Earth’s crust and Ozone layer. This causes an uncontrollable heating in the territory between them (“Global Warming Science”). “Even though these greenhouse gases hold the heat from the sun the greenhouse effect is what keeps the Earth’s temperature suitable for life. Without the greenhouse effect Earth would be frozen and no one would be able to live on it” (“Global Warming- Britannica”). Many people believe that climate change is a myth and that it is not true due to the consequences are too harsh for a normal person to think of, the
This thermal expansion and the melting of land-based ice have already caused a rise of about 8 inches (20 centimeters) in the global sea level.
In order to understand the issue of global warming (also referred to as climate change), you must first understand what it means and how it happens. Global warming is a result of a process known as the greenhouse effect, in which the light and heat from the sun are trapped in the Earth’s atmosphere by greenhouse gases; which subsequently raises the average temperature on Earth. The greenhouse gases responsible for this process are carbon dioxide, methane, nitrous oxide, chlorofluorocarbons, and tropospheric ozone, all of which are released into the atmosphere through naturally occurring processes (Warrick, R. & Farmer, G., 1990).
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
Due rise in temperatures, icebergs and ice crust will melt, what by the way will force sea-level rise and flood islands and continents. If Earth’s oceans water levels will continue to rise, it may also influence on the amount of fallouts, which may destroy living environment and habitat of different species.
Global warming, the phenomenon of increasing average air temperatures near the surface of Earth over the past one to two centuries. Climate scientists have since the mid-20th century gathered detailed observations of various weather phenomena (such as temperatures, precipitation, and storms) and of related influences on climate (such as ocean currents and the atmosphere’s chemical composition). These data indicate that Earth’s climate has changed over almost every conceivable timescale since the beginning of geologic time and that the influence of human activities since at least the beginning of the Industrial Revolution has been deeply woven into the very fabric of climate change. Global warming is happening right now and the balance of the
Due to our mass pollution to the atmosphere, humans are the main cause of global warming. “Since the beginning of the 1900s, the average surface temperature of Earth has risen by 1.3 degrees Fahrenheit” (Levete, 11). Global warming leads to temperature change. Iceberg and glaciers are melting at a rapid rate. This will cause sea level to rise. The Greenland and Antarctica ice sheets “lost an average of 571 trillion pounds (259 trillion kilograms) of mass every year during the six-year study period, making the oceans rise 0.03 inches (0.7 mm)
Last but not least, global warming has caused the polar ice caps to melt. The melting of the polar ice caps will cause the sea levels to rise all over the world. If the sea levels rise just a metre
