Human activities have altered the chemical composition of the atmosphere through the buildup of greenhouse gases?primarily carbon dioxide, methane, and nitrous oxide (Wezp.com Politics category). The heat-trapping property of these gases is undisputed although uncertainties exist about exactly how earth's climate responds to them.
Energy from the sun drives the earth's weather and climate, and heats the earth's surface; in turn, the earth radiates energy back into space. Atmospheric greenhouse gases (water vapor, carbon dioxide, and other gases) trap some of the outgoing energy, retaining heat somewhat like the glass panels of a greenhouse.
Without this natural ?greenhouse effect,? temperatures would be much lower than they are now, and life as known today would not be possible. Instead, thanks to greenhouse gases, the earth's average temperature is a more hospitable 60'F. However, problems may arise when the atmospheric concentration of greenhouse gases increases.
Since the beginning of the industrial revolution, atmospheric concentrations of carbon dioxide have increased nearly 30%, methane concentrations have more than doubled, and nitrous oxide concentrations have risen by about 15%. These increases have enhanced the heat-trapping capability of the earth's atmosphere. Consequently, the temperature of the planet earth is rising.
Fossil fuels burned to run cars and trucks, heat homes and businesses, and power factories are responsible for about 98% of world carbon dioxide emissions, 24% of methane emissions, and 18% of nitrous oxide emissions. Increased agriculture, deforestation, landfills, industrial production, and mining also contribute a significant share of emissions. All these have dramatically reduce the lifespan of living earth.
The quest for efficient energy affects every country on the planet. Worldwide there is an increasing interest in developing clean, reliable alternatives to petroleum fuels. Many smart, safe, and clean alternative power sources are available in the market.
People can easily install these clean power sources at their home as alternative energy to help reducing carbon dioxide emission as well as reducing their utilities bill.
In recent year, people has come up with alternative power sources run their cars in order to reduce the spending on petrol gas and of course, reduce the carbon dioxide emission.
Please play your part on global warming. It is easy and at the same time, you could save money!
The Earth’s surface temperature has risen by about 1 degree Fahrenheit in the past century, with accelerated warming during the past two decades. There is new and stronger evidence that most of the warming over the last 50 years is attributable to human activities. Human activities have altered the chemical composition of the atmosphere through the buildup of greenhouse gases�"primarily carbon dioxide, methane, and nitrous oxide. The heat-trapping property of these gases is undisputed although uncertainties exist about exactly how earth’s climate responds to them.
