On the other hand, many of the more common carbon compounds exhibit strong toxicological effects, such as inhaling coal dust for extended periods of time. Unless you are a coal miner it should not feel like such a threat.
Yet our media cannot quit saying this word. There are two parts to a carbon footprint. The primary footprint is our direct use of fossil fuels, such as when you use your car or ride in an airplane.
The secondary footprint is a measure of the indirect CO2 emissions from the whole life cycle of products we use. Why has this suddenly become a reoccurring trend word in Google search and in our daily news? Wanting to save the earth is trendy. Global Warming is the name of the theory of the phenomena that is the world heating up due to the greenhouse effect and excess amounts of greenhouse gas produced by humans.
Information of the global temperature rising over the past twenty years is abundant and shows evidence of global warming's possibility. Global surface temperatures have increased about.
Seven of the eight warmest years on record have occurred since and the 10 warmest years in history -have occurred since Pre-industrial levels of carbon dioxide prior to the start of the Industrial Revolution were about parts per million by volume ppmv , and current levels are greater than ppmv and increasing at a rate of 1.
The global concentration of CO2 in our atmosphere today far exceeds the natural range over the last , years of to ppmv. The combustion of burning coal, oil and gas produce carbon dioxide which floats into our atmosphere and is creating an atmospheric blanket around the world. The Arctic is feeling the effects of global warming the most.
Average temperatures in Alaska, western Canada, and eastern Russia have risen at twice the global average, according to the multinational Arctic Climate Impact Assessment report compiled between and Glaciers and mountain snows are rapidly melting, for example, Montana's Glacier National Park now has only 27 glaciers, versus in Coral reefs, which are highly sensitive to small changes in water temperature, suffered the worst bleaching ever recorded in , with some areas seeing bleach rates of 70 percent.
Experts expect these sorts of events to increase in frequency and intensity in the next 50 years as sea temperatures rise. Tell me if you use my essay, it would make my day. Posted by Panic at Savage Nugget October 18, at Anonymous January 7, at 8: When an area becomes covered in smog, people feel the effects immediately.
But there are many different kinds of pollution, some visible, some invisible — that contribute to global warming. Generally, any substance that people bring into the atmosphere that has damaging effects on living things and the environment is considered air pollution.
Another pollutant associated with climate change is sulfur dioxide, a component of smog. Sulfur dioxide and closely related chemicals are known primarily as a cause of acid rain. But they also reflect light when released in the atmosphere, which keeps sunlight out and causes Earth to cool. Volcanic eruptions can spew massive amounts of sulfur dioxide into the atmosphere, sometimes causing cooling that lasts for years.
In fact, volcanoes used to be the main source of atmospheric sulfur dioxide; today people are. But a result, not predicted until recently, is that the lower sulfur dioxide levels may actually make global warming worse. Just as sulfur dioxide from volcanoes can cool the planet by blocking sunlight, cutting the amount of the compound in the atmosphere lets more sunlight through, warming the Earth.
This effect is exaggerated when elevated levels of other greenhouse gases in the atmosphere trap the additional heat. Some recent estimates indicate a rise of about 12 per cent in the atmospheric CO 2 content during the period to The present level of CO 2 in the atmosphere is about ppm and this content is rising every year at the rate of about 1. Many persons have implicated the increased C0 2 content of the atmosphere, as a significant contributing factor, to global climatic changes. An increase in the average global temperature by about 3K can potentially induce significant climatic changes of serious concern to farmers.
According to Hansen et al. Some recent estimates suggest that at an annual rate of increase in world fuel use of about 4. Likewise, the value of the missing carbon fraction for the biological budget of the global CO 2 cycle has been estimated to be 1. According to Walsh et al.
In the case of carbon footprint it is the amount of Carbon Dioxide or other carbon compounds (green house gases) emitted into the atmosphere by human activities. By simply going about our daily lives of driving to work or running home appliances we are producing more CO2 because each is powered by energy that rely on the combustion .

A carbon footprint is the amount of carbon dioxide (CO2) emitted as a direct or indirect result of an activity (Yarrow, Joanna. How to Reduce Your Carbon Footprint: ). Earth’s biological cycle produces carbon dioxide and supports plants and other microorganisms to grow (Walser, Maggie L. " Carbon Footprint.").
