Global warming is the phenomenon of potential increase in temperature of the earth's atmosphere due to trapping of carbon dioxide and other gases. This is also known as "the green house effect" or the phenomenon of trapping of the sun's warmth in the lower atmosphere.
With the advancement of science man has made countless inventions for human comfort. Many of them prove very useful together to set up and grow an advanced society. But in this process of making the world the better place to live in he started exploiting the nature.
As human-caused biodiversity loss and climate disruption gain ground, we need to keep our sights clear and understand that the measure of a threat is not a matter of whether it is made on purpose, but of how much loss it may cause. It's an ancient habit to go after those we perceive to be evil because they intended to do harm.
It's harder, but more effective, to "go after," meaning to more effectively educate and socialize, those vastly larger numbers of our fellow humans who are not evil, but whose behavior may in fact be far more destructive in the long run.On Earth, the major natural greenhouse gases are water vapor, which causes about 36-70% of the greenhouse effect; carbon dioxide (CO2), causes 9-26%; methane (CH4), which causes 4-9%; and ozone, which causes 3-7%.Some other naturally occurring gases which contribute very small fractions of the greenhouse effect is nitrous oxide, it is increasing in concentration owing to human activity such as agriculture. The atmospheric concentrations of CO2 and CH4 have increased by 31% and 149% respectively above pre-industrial levels since 1750. These levels are considerably higher than at any time during the last 650,000 years, the period for which reliable data has been extracted from ice cores.
From less direct geological evidence it is believed that CO2 values this high were last attained 20 million years ago.About three-quarters of the man-made emissions of CO2 to the atmosphere during the past 20 years are due to fossil fuel burning. The rest of the anthropogenic emissions are predominantly due to land-use change, especially deforestation. Deforestation, burning of forest, use of pollutant emitting vehicles and appliances etc are the major sources of these harmful gases.
Now the effects of these man made hazard can be seen on almost everywhere. The temperature of the earth's atmosphere is rising every year making it difficult for various other creatures to survive. The rising temperatures are causing glaciers to melt which are increasing the level of seawater causing floods and destruction. Rainfall and climate are getting disturbed. The diseases are increasing and the Global warming is expected to extend the favorable zones for vectors conveying infectious disease such as dengue fever and malaria etc.
It isn't surprising that rising carbon-dioxide levels and warming climes will alter the biology, chemistry and geographical distribution of plants. After all, many plants thrive when there's more carbon dioxide in the air, or when it's warmer.
The remedies are to stop or reduce use of all such tools that cause global warming and grow trees. Global warming problem is now developing as the biggest threat to the God's most beautiful creation.. To eradicate or possibly delay it, it requires the continuous and together effort of the whole mankind.its now or never now.
Don't just wait for Not enough people dying yet, and not enough property destroyed. Have will, join the mission and together we can and we will make it different. SAVE EARTH-SAVE NATURE-SAVE MANKIND-SAVE YOURSELF-its our duty now contribute your share to environment.
