    What is GlobalWarming???

    Global warming is the increase inthe average temperature of the

    Earth's near-surface air andoceans since the mid-20thcentury and its projected

    continuation .

    What are the causes ofGlobal Warming???

    An increase in global temperaturewill cause sea levels to rise and

    will change the amount andpattern of precipitation,

    probably including expansion of

    subtropical deserts. Thecontinuing retreat

    of glaciers, permafrost and sea

    iceis

    expected, with warming

    being strongest in the Arctic.Other likely effects include

    increases in the intensity

    of extremeweather events, speciesextinctions, and changes

    in agricultural yields. Globalwarming could affect seasons,

    sea level and disrupt ecosystems.

    What are the effectsof Global Warming???

    The effects of globalwarming and climate change are

    of concern both forthe environment and human life.

    Evidence of observed climatechange includes the instrumentaltemperature record, rising sea

    levels, and

    concentrations". It is predictedthat future climate changes will

    include further global warming(i.e., an upwardtrend in globalmean temperature), sea level

    rise, and a probable increase inthe frequency of some extremeweather events. Ecosystems are

    seen as being particularlyvulnerable to climate change.Human systems are seen as

    being variable in their capacity to

    adapt to future climate change.To reduce the risk of largechanges in future climate, many

    countries have implementedpolicies designed to reduce theiremissions of greenhouse gases.

    How we can prevent

    it???Step1Drive less. Take bikes, walk or

    carpool whenever possible.Step2

    Consider investing in a hybrid orelectric vehicle to help preventagainst further global warming.

    Replace all the lightbulbs in andaround your home with energy-efficient fluorescents that use

    fewer watts for the sameamount of light.

    Step4Clean or replace your filters

    monthly.Step5Choose energy-efficient appliances

    when it's time to buy new ones.

    Step6

    Decrease your air travel.Step7Wash clothes in cold water and

    line-dry whenever possible.Step8Use a low-flow showerhead, which

    will lessen the hot water usedbut not drop your water pressure

    in the shower.

    Step9

    Cut down on your garbagebuyfewer packaged materials toprevent further global warming.

    Step10Unplug electronics when they arenot in use, because they still take

    up energy. At the very least, turnitems off when theyre not beingused.

    Step11

    Run the dishwasher and clotheswasher only when you have a fullload, and if available, use the

    energy-saving setting.

    Step12Insulate your home better, anddont forget to repair or replace

    worn caulking or weather-stripping. Insulateyour water heater .

    Buy recycled paper products andrecycle as much of your waste aspossible.

    Step14Bring your own reusable canvas

    grocery bags when grocery

    shopping.Step15

    Plant a tree.

    Step16Have an energy audit done on your

    home so you can find the troubleareas and fix them.

    Step17Use nontoxic cleaning products.

    Step18

    Shop locally for food. A farmersmarket is an excellent place tovisit. And choose fresh food over

    frozen foods. Fresh takes less

    energy to produce.

    Step19Keep your car tuned up, and check

    tire pressure often to save gas.Step20Eat less meat and

    more organic foods in your dietto do your part in preventingglobal warming
