Global warming is when the earth heats up (the temperature rises). It happens when greenhouse gases (carbon dioxide, water vapor, nitrous oxide, and methane) trap heat and light from the sun in the earth’s atmosphere, which increases the temperature. This hurts many people, animals, and plants. Many cannot take the change, so they die.

Global warming is caused due to the heating effect in earth. this is mainly due to the sun rays which fall on earth some part of them get absorbed and some reflected by the earth get absorbed by CO2 molecules present in the atmosphere. this leads to global warming. More will be the CO2 concentration more will be global warming.

normally what starts worldwide warming is the top of an ice age. From that factor on the temperature traits upwards with occasional setbacks. the international warming your challenge is approximately is easily Anthropogenic worldwide Warming or AGW, it is brought about via folk burning fossil fuels and liberating the CO2 it is composed of. there are various extra efficient greenhouse gases than CO2, almost each and all of the warming is finished via water vapor interior the ambience, yet CO2 is the single that human activity releases maximum. CO2 is at the instant at approximately 383 areas according to million interior the ambience, or approximately .04% of the completed. If CO2 is the perpetrator then you certainly might say that the present warming began as quickly as we began to apply fossil fuels in earnest, at first of the commercial Revolution. This precedes using petroleum, people used coal long till now they discovered the thank you to apply oil for gas. The chinese language have been applying it approximately 3,000 years in the past even though if it began for use as element of the commercial Revolution in 1678, then as a skill source in steam engines interior the overdue 18th century.

Simple answer.Global warming is caused by trapping solar radiation by the excesive particulate matter, gas emmissions, Chlorofulocarbon and co2 that is caught up in the entire atmosphere of Earth. This happens in two ways. One, when Solar radiation enters the Earth and when the radiation is bounced back by the biospheric film of the Earth into the atmosphere.At the uppermost level it damages the ozone layer, which is meant for maintaining the equilibrium betwen the input and output of solar and even cosmic radiation.

Global warming occurs when the suns heat is trapped in the earth's atmosphere. Excessive use of Green house gases results in the build up of a blanket of gases under the ozone layer
the suns heat which gets reflected back is trapped under this layer

earth is blanketed by ozone which filters the u v radiation and leaves part of it to reach earth and allow the gases from earth to reach atmoshpoere it almost works like a diaphram the green house gases like methane, cfc, clorine, carbon are some of the enemies which weakens ozone layer and now it has almost created a hole because of which u r rays are comming into earth unchecked and also there is drastic change in climatic conditions if there is a marginal change in atlantic region then probably some of the islands in and around india will get submerged that will be the effect

When the CO2 is developed in the air automatically the earth temperature increases that is Global Warming.

Hi,
It is formed from the amount of pollution in the environment. Pollution leads to increased tempratures and hence leads to melting of ice in coldest regions.
It also leads to ozone depletion which again increases the temprture which is called global warming.

Global warming is caused due to the depletion of the Ozone layer in the atmosphere. This occurs due to extensive use of CFC.

the rays of the sun brings the heat to the earth . afraction of this heat is reflected back to space ;this kept the earth warm enought but now this changed as the precentage of the co2 increased .
carbon di-oxide form something like a glass cover around the earth this cover allows the heat to enter but dont allow it to leave the earth atmospher
