Climatologists (scientists who study climate) have analyzed the global warming that has occurred since the late 1800's. A majority of climatologists have concluded that human activities are responsible for most of the warming. Human activities contribute to global warming by enhancing Earth's natural greenhouse effect. The greenhouse effect warms Earth's surface through a complex process involving sunlight, gases, and particles in the atmosphere. Gases that trap heat in the atmosphere are known as greenhouse gases.

The main human activities that contribute to global warming are the burning of fossil fuels (coal, oil, and natural gas) and the clearing of land. Most of the burning occurs in automobiles, in factories, and in electric power plants that provide energy for houses and office buildings. The burning of fossil fuels creates carbon dioxide, whose chemical formula is CO2. CO2 is a greenhouse gas that slows the escape of heat into space. Trees and other plants remove CO2 from the air during photosynthesis, the process they use to produce food. The clearing of land contributes to the buildup of CO2 by reducing the rate at which the gas is removed from the atmosphere or by the decomposition of dead vegetation.

A small number of scientists argue that the increase in greenhouse gases has not made a measurable difference in the temperature. They say that natural processes could have caused global warming. Those processes include increases in the energy emitted (given off) by the sun. But the vast majority of climatologists believe that increases in the sun's energy have contributed only slightly to recent warming.

Steps To Stop Global Warming

• Drive an energy-efficient car. For instance, hybrid cars run on gas and electricity. The average hybrid can save 16,000 pounds of carbon dioxide (which is considered a greenhouse gas emission) a year! And $3,750 in gas money! Pay attention to the MPG (miles per gallon) of a car you may want to buy. No SUVs! Read consumer reports about which vehicles are most energy-efficient.


• While on the subject of cars, make sure that tires are properly inflated or else you can release as much as 250 extra pounds of carbon dioxide annually. If you have an old air filter, that can also cost an extra 800 pounds of CO2 and $130 a year. Check these monthly.

• Check your water heater (or don’t use it at all). Keeping it at less than 120 degrees F can save money and emissions. An extra two degrees can save 2,000 pounds of carbon dioxide and $98 a year! If you go tankless, you can save 300 pounds of CO2 and $390 a year.

• Also, don’t use hot water if you don’t need to, like when doing laundry. There are special detergents formulated for use with cold water. You don’t need to take cold baths or anything, but a few minutes early out of the shower helps. Showers account for 2/3 of water heating costs and shorter showers can mean reducing 350 pounds of carbon dioxide a year. Try using low-flow showerheads too.

• Speaking of laundry, try air-drying your clothes instead of using a dryer… this can save 700 pounds and $75 a year.

• Take care with your appliances. Unplug them when you don’t use them; this saves 1,000 pounds and $256 a year because appliances still use energy if they’re plugged in, even when not in use. You can get a power strip with an on-off switch so you can keep plugs in but they don’t all have to be used. Also try going with blue Energy Star label products.

• Look at your light bulbs! Get energy-saving ones. Compact fluorescent bulbs use 66 percent less energy and replacing just 3 regular bulbs can mean saving 300 pounds and $60 each year.

• Buy recycled products. Also try donating or selling instead of throwing away… craigslist.com is a great way to do that!

• As far as consumerism, try buying products with less packaging! It kills me going through all the layers of plastic covering and plastic wrap and paper wrapping and ties and such! Buying in bulk can mean less packaging and less money being spent. Plus more food is just better to have around.

• Ceiling fans are a pretty harmless way to cool down a room without using an air conditioner. It uses less energy and can be considered a comfort.

• Plant trees! Not only do they suck up carbon dioxide, provide cleaner air and save 2,000 pounds of CO2 a year, but you can strategize where you place them so they can shade your home. Deciduous trees lose their leaves in the winter so sun can warm your home as well.

• Install blinds in your windows and keep windows and doors shut during the day to keep it cooler.

• Buy organic. Large agricultural sources use chemicals, which pollute water and require energy to produce. And use cloth bags while you’re at it instead of those plastic bags!

Climate change means change of climat,attributed directly or indirectly by human activites that alter d composition of global atmosphere, and which is in addition to natural climate variability,observed over considerable time periods.
There r multiple reasons 4 global warming;carbon di oxide-50 to 60%, CFCs[chloro floro carbons]-20 to 25%, nitrogen oxides[NOx]-5 to 10%, methane gas[CH4]-14% ,water vapours[H2O] n to some extent ozone[O3] present in d atmosphere as a pollutant. Sources of all these pollutants r both anthropogenic[human activites] n natural.
Various strategies could b adopted against global warming; relay on alternate enviromental frindly fuels, scrubbing of stack gases[gases which cause glogal warming] with silicates,more forestation n plantation[bcoz plants act as sink for CO2 n 2 use machies both industrial n domestic of formal n informal enviromental regulations.
