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 Threat of Global Warming Through the eyes of most scientists, global warming is seen as a very serious and severe threat. The actions taken by humans, such as industry and consumption of fossil fuels plus the increase in population and agriculture have played a big part in global warming. If something is not done soon the results could be very bad. By the middle of the twenty first century, there is evidence that the Earth will be warmer than it has been at any time in human history, and quite possibly since the end of the dinosaurs, some 65 billion years ago. If we stay at the rate we are now (fossil fuel consumption / growth in population) then within the next two century the Earth's air might not be fit to breath.
The causes and effects of Global Warming The Earth has experienced considerable climate change for the last several centuries. There have been many explanations toward the main causes of the increased warming of the planet, but according to IPCC climate report: human impact is unequivocal. The recent weather events that Canada has experienced in Toronto and Calgary have proven Canada is at great risk from the climate change. A UN panel said it was more certain than ever that humans were the cause of global warming and they also predicted temperatures could rise from 0.3 to 4.8 degrees Celsius in this century. According to the IPCC report it is certain that pollution from burning fossil fuels is changing earth’s climate.
For the past few hundred thousand years the amount of greenhouse gases in the earth’s atmosphere have been at natural and comfortable life sustaining levels. But in just the last one hundred or so years, since the beginning of the industrial revolution, the levels of greenhouse gases, in particular carbon dioxide, have gone through the roof. Global warming can, and will, if not stopped, have devastating effects on our planet; possibilities include rising temperatures, droughts, mass extinctions and much more. Humans are having a strong, negative, impact on the environment. The “greenhouse effect” is the most prominent cause for the rise of global temperatures.
Is global Warming Real? What is Global Warming? Why is it important, or not important? Well, global warming is the gradual increase in the temperature of the earth’s atmosphere generally attributed by the increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants. Global Warming is real and is a current problem that we live with every day.
What is global warming and what does it mean. Global warming is any substantial change in Earth’s climate. Global warming refers to climate change that causes an increase in the average temperature of the lower atmosphere. Global warming can have many different causes, but it is most commonly associated with human interference, specifically the release of excessive amounts of greenhouse gases. Global warming is also known as the greenhouse effects.
100? 1000? year? Global Warming is deteriorating as time goes on and humans are the main cause of it and if we don’t do something to stop it we are endangering our future. Global Warming is the phenomenon of increasing average air temperature near the surface of earth over the past one to two centuries.
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.
Global Warming causes rising sea level from glacier melting, unusual weather, increased temperature, droughts and floods, changes in ocean currents and climate shifts. I believe that global warming is the human fault because humans create more pollution by burning fossil fuels, expanding the greenhouse gases and cutting down and burning trees also release carbon dioxide. Releasing such gases into the atmosphere not only effects the atmosphere itself but also effects the entire earth and its population. Global Warming is the increase of Earth's average surface temperature due to effect of greenhouse gases, such as carbon dioxide emissions from burning fossil fuels or from deforestation, which trap heat that would otherwise escape from Earth. This is a type of greenhouse effect.
Often many small farmers will each clear a few acres to feed their families by cutting down trees and burning them in process known as “ slash and burn” agriculture. Therefore, not all deforestations is intentional. Some is caused by a combination of human and natural factors like wildfires and subsequent overgrazing, which may prevent the growth of young trees. Deforestations has many negative effects on the environment. The most dramatic impact is a loss of habitat for million of species.
