What is the main cause for global warming?

Question

as it is increasing rapidly

Answer 1

Hello brother,
The main reason for increasing global warming is the extensive usage of perfumes. The another reason is the usage of refrigirators at a wide range. The gases which it emits severly damage the ozone layer. Due to this, the UV rays and the other harmfull rays from sun reach out the earth, causing the problem at verge of increasing. Alongwith this, pollution, smoking, human ignorance, etc are also the causes of global warming.

Answer 2

the main cause is the use of an substance like fuel which gives off CO2 on burning. CO2 makes a layer around the atmosphere thereby trapping the infra red (IR) waves which reflect from the surface of the earth and increases the temperature at the earth's surface. This is increasing the temperature and casusing global warming

Answer 3

visit www.dmns.com , go to on line activities and look at the dinosaur period when global warming is first mentioned.
Then think back to the Ice age and what it took to get us out of the Ice age.
Volcanic activity like Mt. Vesuvius cause global warming.
Fires cause global warming. Carbon dioxide causes global warming.

Trees use carbon dioxide and produce oxygen.
Yet our forest are being used so rapidly to keep up with the housing market, paper and toilet paper and napkin sales.

The very thing we need is being destroyed rapidly.
Laws are being set for replacement of forest but not enforced.
When they go in to log an area, they are leaving all the leftovers scattered on the ground making it difficult for light to reach the new trees that should grow.

We must get the laws that are set enforced.
Other than that we must accept the natural process of global warming and adapt as we are capable of doing.

We must embrace change, but use care in our doings.

Global warming has begun since the industrial revolution and it is getting worse recently. Even though the increase of greenhouse gases such as CO2 is thought to be the main cause for global warming, its impact on global climate has not been revealed clearly in rather quantitative manners. However, researches using General Circulation Models(GCMs) have shown the accumulation of greenhouse gases increasing the global mean temperature, which in turn impacts on the global water circulation pattern. This changes in global water circulation pattern result in abnormal and more frequent meteorological events such as severe floods and droughts, generally more severe than the normal ones, which are now common around the world and is referred as an indirect proof of global warming. Korean peninsula also cannot be an exception and have had several extremes recently. The objective of this research is to predict the hydrological environment changes in the Korea peninsular due to the global warming.

In this research, we have used the mesoscale atmospheric/hydrologic model (IRSHAM96) for distributing boundary conditions(that is GCM output according to the increasing scenarios of CO2 concentration by IPCC) into inner domain considering its topography, land use and soil characteristics to predict the changes in precipitation, evapotranspiration and temperature in the Geum River Basin, one of the four large river basins in Korea peninsular.

From the simulation results for 1CO2 and 2CO2 situations, it has been known that daily mean precipitation is decreased, but daily mean evapotranspiration and air temperatures are increased due to the increasing of CO2. Therefore, we can predict that the frequency of drought occurrence in the Geum River Basin will be increased due to the global warming.-

Answer 5

Because people are letting deadly gasses into the air and it is making horrible things happen to the planet such as glaciers are melting and that is making the water flow WAY over what it should be. And if you want to fight it, go to the webdite called fightglobawarming.com. And if you want to save about 10 animals, turn of the ights when you leave th room. I might only be 8, but I'm smart.

Answer 6

Stefan's law states that all bodies above zero kelvin emit thermal radiations.

Earth emits thermal radiations and earth also absorbs thermal radiations emitted by the sun.

Had there been no atmosphere ,the earth would become very cold at night due to emission at night (sun is not present at night)

Carbon dioxide, water vapor, methane present in the lower atmosphere absorb the heat radiations emitted by the earth at night, Lower atmosphere is kept warm at night.

The warm lower atmosphere re radiates thermal radiations back to earth at night and this keeps the earth warm at night,

As the concentration of carbon dioxide, methane increases in atmosphere ,the absorption and re radiation increases which increases temperature and leads to global warming

Answer 7

A punishment for played with nature. By the way have read the warning issued by UNESCO, yesterday in Bangkok meeting, attended by Scientists from 105 Nations. If we can not control now. The Earth's average temperature in 2015, will rice by 2* C. Which results in melting of All ice in Himalayas, and at polar regions. Resulting in rise in average Sea level and expected damage to all coastal region, including the submersion of Metros. They have warned all Countries to take immediate action, in next 8 years. If this happens, the consequences are unpredictable.

Answer 8

Carbon dioxide and other air pollution that is collecting in the atmosphere like a thickening blanket, trapping the sun's heat and causing the planet to warm up. Coal-burning power plants are the largest U.S. source of carbon dioxide pollution -- they produce 2.5 billion tons every year. Automobiles, the second largest source, create nearly 1.5 billion tons of CO2 annually.

Here's the good news: technologies exist today to make cars that run cleaner and burn less gas, modernize power plants and generate electricity from nonpolluting sources, and cut our electricity use through energy efficiency. The challenge is to be sure these solutions are put to use.

Answer 9

only bcoz of pollution level increasing
the co2, co level & other dangerous gases level increase in such a way that ozone layer bcoms thin. This increases the incoming of uv radiations leading to global warming

Answer 10

As told by the real scientists not owned by interest groups - increased carbon dioxide is trapping heat and reflecting it back to earth.

Increased burning of fossil fuels is emitting more CO2 than can be absorbed by plants or oceans.

The world needs to act soon - America, as the worlds biggest emissions vandal needs to do much more to cut this unsustainable, greedy habit.
