It can be hard to tell if it is natural or man made, but either way, in 1995 it was the hottest year on record, research shows from the British Meteorological office. Some scientists predict that if green house gasses are not reduced quickly, temperatures could raise the average temperature 1.8 to 6.3 degree Farenheit by 2100. The average temperature rose 1.8-degree Fahrenheit from 1850 to about 1998. This says the temperature is rising faster because of more fossil fuels and Co2 being pumped into the atmosphere. These increases of temperature, scientists predict, could cause sea levels to rise 20 inches and more.
So the co2 and burning gases causes the increase of global warming (http://www.nmsea.org/Curriculum/Primer/Global_Warming/fossil_fuels_and_global_warming.htm) Radiations: Radiations also increase the global warming. Some elements emitted radiations naturally so that the temperature of is increased. : Melting of the ice caps : loss of habitat near the poles. Polar bears are now thought to be greatly endangered by the shortening of their feeding season due to dwindling ice packs. Greenhouse gases: Greenhouse gases are the the gases that block the ultraviolet rays coming from the sun on earth.
Global warming is a war that we should not get involved with because we will lose if changes aren’t made soon. Global warming is the rapid increase in earth’s average surface temperature over the past century due to the fact that greenhouse gases are being released into the atmosphere increasing the earth’s average temperature (EarthObservatory.NASA.org). There are many contributing factors that play a role into the cause of global warming. Greenhouse gasses are gasses such as Carbon Dioxide, Methane, Nitrous Oxide, and F-gasses that trap heat in the atmosphere. The heat that is trapped in the earth’s atmosphere is a slowly melting glaciers, cause sea levels to rise and is messing with the weather patterns.
The hard face is that despite what many nations, companies, cities and people are starting to do to reduce their global warming emission. The world is putting out more carbon dioxide into the air than ever before. The current amount is 385 parts per million (ppm), higher than ever in the past 800,000 years (Gary Braasch, 2005). Global warming is the increase in the average temperature of the Earth's near-surface air and oceans in recent decades and its likely continuation. Rise in global temperature will cause sea level to rise, and is likely to increase the intensity of extreme weather events and to change the amount and pattern of rainfall.
How does Greenhouse effect impact climate change? Kenneth Hare reviews the scientific evidence on the greenhouse effect and explained that warming on global and increased greenhouse gases is the main issue that impact climate change. Human activity is the one who causes the greenhouse effect. The natural greenhouse effect is benefit to our world and become probable to making life on earth, but the temperature is very high nowadays that harm human, plant, and animal life. For example, the natural resource such as petrol for vehicles and electricity for our necessary needs will produce more than billions of carbon to the atmosphere every year that cause climate change every day in our earth.
“The most plentiful human-generated greenhouse gas is carbon dioxide, released by the burning of fossil fuels.”(Global Warming 2001). The growth in population and mass industrialization have put Mother Nature to her knees, begging for the cooperation of human kind and nature to compromise a fair balance of existence. If global warming continues “Planet earth will turn into our sister planet Venus and temperatures will rise to 250 degrees. We are killing it for future generations to come, and eventually it will be too late for anything to be done. We are leaders that are misleading” (11th hour).
Carbon dioxide, water vapor, methane and nitrous oxide are the most common greenhouse gasses. Greenhouse gases cause the radiant heat of the sun to be trapped in the Earths lower atmosphere which causes global warming. If there weren’t any greenhouse gasses, the earth would be really cold due to very little sun rays being absorbed on the earth. Global warming can and will lead to several problems that affect the environment in which we humans live in. These problems can lead to warmer temperatures all around the world, it can endanger animals and the wildlife, and it can lead to widespread flooding from the glaciers melting.
The rise in the temperature results in melting the glaciers. If temperature keeps rising, glaciers will continue melting, and some could disappear completely. As a result, sea levels will rise which will cause risks to many cities especially the ones that are near the ocean. Cities near the sea will wipe out and might completely vanish. According to Brandon Baker, author in Ecowatch , argued that “The rapidly melting section of the West Antarctic Ice Sheet is expected to lead to at least 4 feet of global, sea-level rise over the next two-plus centuries, and at least 10 feet thereafter” ( How Melting Antarctic Glacier Will Make These 14 Coastal U.S. Attractions Look, para.
One main piece of evidence is the global temperature rise. “The 20 warmest years having occurred since 1981 and with all 10 of the warmest years occurring in the past 12 years” (“Climate Change: How do we know?” 1). The temperature increase will hurt the earth’s atmosphere, allowing it to absorb more harmful gases and other pollutants. Not only does it harm the atmosphere it also damages earth’s surface. It will cause the surface to heat up too much and it could crack, split, and in some cases, melt depending on the location.
Global Warming As the world's expanding population burns large quantities of fossil fuels and simultaneously cuts down large expanses of forests worldwide, the concentrations of CO2 and other greenhouse gases are building up in the atmosphere. "The green house effect is the (imperfect) analogy used to explain the atmospheric phenomenon that keeps our planet warm enough to sustain life." There is mounting evidence that this shift in Earth's atmosphere will lead to global changes and potentially major climatic disruptions. The major concern is not that the greenhouse effect is real;"we wouldn't be here if it wasn't." It is that it "may be exacerbated by anthropogenic increases in the effective gasses, threatening a disruption to the equilibrium between incoming and outgoing energy, and a resulting average global warming."
