Facts about Global Warming

These days everywhere we are reading about Global Warming it is a hot topic on internet. Everybody wants to know actually what it is, though we know many things about Global Warming but still we don’t know many things about it.

May there are many peoples who doesnt know about Global Warming what actually it is. Given point is for them.

What is Global Warming?

Global Warming refers to a rise in the average temperature of Earth’s atmosphere due to the presence of greenhouse gasses in the atmosphere.

Greenhouse gasses are comprised mainly of Carbon Dioxide, Nitrous Oxide, Methane, and Ozone.

The atmosphere is warmed naturally by the “greenhouse effect” caused by these gasses, which trap the sun’s radiation and act as a sort of “thermal blanket” keeping the Earth within a mostly livable temperature band averaging around 59 degrees Fahrenheit. If the earth had no global warming or blanket of atmospheric gasses keeping us warm, the planet would be about 90 degrees cooler than it is - very cold; you and I would not be here if it weren’t for global warming.

Global Warming Skeptics
The global warming skeptics are of the view that the global warming is a good phenomenon and should not be stopped. There are various benefits of global warming according to them. According to the skeptics, the global warming will increase humidity in tropical deserts. Also the higher levels of carbon dioxide in the atmosphere trigger plant growth. As predicted, due to the global warming the sea levels will rise. But this can be readily adapted. Another argument of global warming skeptics is that earth has been warmer than today as seen in its history. The thought is that global warming is nothing to get afraid of because it just takes us back to a more natural set of environment of the past. Animals and plants appeared to do just fine in those eras of warm climate on the earth. According to few skeptics, the present chilly climate on the earth is an abnormality when judged over the geographical scale. Over geologic time, the earth’s mean temperature is 22 degrees C, as compared to today's 15.5 degrees C.

Here are some points everybody should know about Global Warming.

1. Water vapor is the most important, abundant greenhouse gas. So if we’re going to control a greenhouse gas, why don’t we control it instead of carbon dioxide (CO2)?

water vapor and climate, to fight global warming nations must focus on controlling CO2.
The best way to lower temperature and thus reduce water vapor levels is to reduce CO2 emissions.

2. Global warming and extra CO2 will actually be beneficial — they reduce cold-related deaths and stimulate crop growth.

Any beneficial effects will be far outweighed by damage and disruption

3. Global warming is just part of a natural cycle. The Arctic has warmed up in the past.

The global warming we are experiencing is not natural. People are causing it.
People are causing global warming by burning fossil fuels (like oil, coal and natural gas) and cutting down forests. Scientists have shown that these activities are pumping far more CO2 into the atmosphere than was ever released in hundreds of thousands of years. This buildup of CO2 is the biggest cause of global warming. Since 1895, scientists have known that CO2 and other greenhouse gases trap heat and warm the earth. As the warming has intensified over the past three decades, scientific scrutiny has increased along with it. Scientists have considered and ruled out other, natural explanations such as sunlight, volcanic eruptions and cosmic rays. (IPCC 2001)

4. As the ozone hole shrinks, global warming will no longer be a problem.

Global warming and the ozone hole are two different problems.
The ozone hole is a thinning of the stratosphere's ozone layer, which is roughly 9 to 31 miles above the earth's surface. The depletion of the ozone is due to man-made chemicals like chlorofluorocarbons (CFCs). A thinner ozone layer lets more harmful ultraviolet (UV) radiation to reach the earth's surface.
Global warming, on the other hand, is the increase in the earth's average temperature due to the buildup of CO2 and other greenhouse gases in the atmosphere from human activities.

What you can do to reduce Global Warming.

1.When it is time for a new car, choose a more fuel efficient vehicle

2.Encourage the switch to renewable energy :
Successfully combating global warming requires a national transition to renewable energy sources such as solar, wind and biomass

3. Protect and conserve forest worldwide :
Forests play a critial role in global warming: they store carbon. When forests are burned or cut down, their stored carbon is release into the atmosphere - deforestation now accounts for about 20% of carbon dioxide emissions each year.

4. Switch to green power

5. Reduce waste :
Most products we buy cause greenhouse gas emissions in one or another way, e.g. during production and distribution. By taking your lunch in a reusable lunch box instead of a disposable one, you save the energy needed to produce new lunch boxes.

6.Change Your Lights :
Replacing your old incandescent light bulbs with compact fluorescent light bulbs (CFLs) will help increase your energy efficiency. Replacing one old bulb with a CFL can save you up to $30 over the life of the bulb (generally five years). CFLs use two thirds less energy, give off 70 percent less heat and last up to 10 times as long as conventional bulbs. You'll help stop global warming by reducing air pollution caused by power plants.
