What is meant by global warming?

Question

plz share your views

Answer 1

  the depletion of Ozone(O3) due to CFC and other some gases is named as Global warming

Answer 2

global warming is a process in which the temperature of the earth exceeds its normal. this leads to melting of the ice and causes increase in the onean levels. this is a threat to human life.                  

basically global warming is caused due to increase in air pollution and increase in the propartion of CO in the atmosphere. this gas captures the heat and retains it within the earth atmosphere.

i hope this helps u.........

Answer 3

heat coming out from factories, vehicles and water polution, air pollution all becomes and part of global warming..

Answer 4

it is increased trapping of green house gases as co and carbon dioxide which result in trapping of more heat

Answer 5

the total change in atmosphere with extreme conditions means global warming

Answer 6

people are using too much energy

and causing the earth to warm which is melting the icecaps and glaciers so the earth will flood and we will all die unless you can swim

Answer 7

global temp rising due to increase of greenhouse gases like CO,CO2...

Answer 8

'Global Warming' is the term used to describe a gradual increase in the earth's ground and atmospheric temperatures.Now the earth's temperature(average) is 15 °C , it is 14 degrees centigrade 100yrs ago and it is projected that global temperatures will increase by 2-3 degrees centigrade  in the coming decades which is a rapid increase.Even this 2-3 degrees inc can spell a massive destruction...

*as all the low lying regions in the world will get submerged in the waters because of glacier melting,

*there will be change in the climatic patterns and vegetations ,

*there will inc in the frequency and intensity of natural hazards(droughts and floods)

*health hazards

*adverse impact on economy and othr cascading effects.......................

This rise in the temperatures is because of green house effect caused by green house gases (co,co2,ch4,cfc's - carbon emissions-mainly because of burning of fossil fuels).These gases which stay for a long period in the atmosphere  after being released ,obstruct or prevent the terrestrial radiation(radiation from the earth) to escape into the space. But these gases are transparent to the solar radiation(radiation from sun,absorbed by the earth surface and clouds).......so the balance between the incoming heat energy and the outgoing heat energy is disturbed causing rise in the global temperatures.The Global Warming.

The exact reason behind the changes in the earth's climatic conditions (at different geological periods - from different ice ages to warm periods) is still not known.But according to IPCC and other researches it is established that the  present climatic change/global warming is because of increased Carbon emissions.

Answer 9

global warming is abt coooling of earth rather than warming in green  house due to biger exclusion of gases like co2 ,so2 etc ..they usually block the heat which gets out of the atmospher in the universe and makes earth warm ...and fianlly the upper belt of sea beecmes thiner .. due to..mixing of fresh water frm ..  alantic...ice..and fianlly thre will be an ice age ..for more in formation search global warming on google

Answer 10

the earth's temperature is rising

Answer 11

the greenhouse effect is increasing the temperature of the globe (whole world) & this is leading to several changes in the climatic conditions of the whole world. this is known as 'global warming'.

this global warming is alone responsible for the melting of glaciers which, in the future will lead to the submergence of the coastal areas all over the globe (this is the very true prediction of the geologists).  

Answer 12

Global warming is causing animal extinction along with polluting our earth as well as the atmosphere it is a serious thing to be alarmed for do research you'll find out how much its costing us people  

Answer 13

Some people think they can average the earths temperature . Examine it ,they used old data to show that the world is warming,but no one can give an accuracy of the data.  

Answer 14

The earth is warmer now than it was 10,000 years ago, during the last extensive glaciation, when New York City was buried under one mile of ice.

In addition, the earth is warming out of a "little ice age" that ended a few hundred years ago.

For reasons no one knows, we are currently in an ice age (glaciers in Antarctica and Greenland), and cycle between little glaciation (like now) and very extensive glaciation (like 10,000 years ago).  The geological evidence is compelling that we will enter another extensive glaciation within a few thousand years or so.  The Antarctic plate being at the south pole may be one reason for our ice age.

"Anthropogenic global warming" (AGW) is the theory that:

a. an increase of 1/3 in carbon dioxide in the earth's atmosphere over the past 150 years or so is the result of mankind burning fossil fuels

b. the added CO2 has led to an increase in average global temperature of approx. 0.6C over the past 100 years

c. average global temperature will continue to increase, and a wide range of bad things will happen to the earth's environment and its inhabitants

Satellite data shows no net warming over the past ten years, and some cooling over the past couple of years.  During this time CO2 has increased steadily.

No one who studies the issue (on any side) disagrees with any of the statements above.

Answer 15

I believe the correct term now is "climate change", which is really caused by "global warming", but scientists like to be special.

Global warming in this case refers to the increase in temperature of the earth's atmosphere due to increased green-houses gasses, such as carbon dioxide. These gasses are being wrapped around the planet like a blanket, keeping the heat in.
