Global Warming?That's my question,Global Warming?

Question

Just the usual global warming questions.Can we stop?Fix it?What are we suppose to do?Is the world comignt o a slow end?Those questions.

Answer 1

global warming, the gradual increase of the temperature of the earth's lower atmosphere as a result of the increase in greenhouse gases since the Industrial Revolution.
The temperature of the atmosphere near the earth's surface is warmed through a natural process called the greenhouse effect. Visible, shortwave light comes from the sun to the earth, passing unimpeded through a blanket of thermal, or greenhouse, gases composed largely of water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Infrared radiation reflects off the planet's surface toward space but does not easily pass through the thermal blanket. Some of it is trapped and reflected downward, keeping the planet at an average temperature suitable to life, about 60°F (16°C).

Growth in industry, agriculture, and transportation since the Industrial Revolution has produced additional quantities of the natural greenhouse gases plus chlorofluorocarbons and other gases, augmenting the thermal blanket. It is generally accepted that this increase in the quantity of greenhouse gases is trapping more heat and increasing global temperatures, making a process that has been beneficial to life potentially disruptive and harmful. During the 20th cent., the atmospheric temperature rose 1.1°F (0.6°C), and sea level rose several inches. Some projected, longer-term results of global warming include melting of polar ice, with a resulting rise in sea level and coastal flooding; disruption of drinking water supplies dependent on snow melts; profound changes in agriculture due to climate change; extinction of species as ecological niches disappear; more frequent tropical storms; and an increased incidence of tropical diseases.

Among factors that may be contributing to global warming are the burning of coal and petroleum products (sources of carbon dioxide, methane, nitrous oxide, ozone); deforestation, which increases the amount of carbon dioxide in the atmosphere; methane gas released in animal waste; and increased cattle production, which contributes to deforestation, methane production, and use of fossil fuels.

Much of the debate surrounding global warming has centered on the accuracy of scientific predictions concerning future warming. To predict global climatic trends, climatologists accumulate large historical databases and use them to create computerized models that simulate the earth's climate. The validity of these models has been a subject of controversy. Skeptics say that the climate is too complicated to be accurately modeled, and that there are too many unknowns. Some also question whether the observed climate changes might simply represent normal fluctuations in global temperature. Nonetheless, for some time there has been general agreement that at least part of the observed warming is the result of human activity, and that the problem needs to be addressed. In 1992, at the United Nations Conference on Environment and Development, over 150 nations signed a binding declaration on the need to reduce global warming.

In 1994, however, a UN scientific advisory panel, the Intergovernmental Panel on Climate Change, concluded that reductions beyond those envisioned by the treaty would be needed to avoid global warming. The following year, the advisory panel forecast a rise in global temperature of from 1.44 to 6.3°F (0.8–3.5°C) by 2100 if no action is taken to cut down on the production of greenhouse gases, and a rise of from 1 to 3.6°F (0.5–2°C) even if action is taken (because of already released gases that will persist in the atmosphere).

A UN Conference on Climate Change, held in Kyoto, Japan, in 1997 resulted in an international agreement to fight global warming, which called for reductions in emissions of greenhouse gases by industrialized nations. Not all industrial countries, however, immediately signed or ratified the accord. In 2001 the G. W. Bush administration announced it would abandon the Kyoto Protocol; because the United States produces about one quarter of the world's greenhouse gases, this was regarded as a severe blow to the effort to slow global warming. Despite the American move, most other nations agreed later in the year (in Bonn, Germany, and in Marrakech, Morocco) on the details necessary to convert the agreement into a binding international treaty, which came into force in 2005 after ratification by more than 125 nations.

Improved automobile mileage, reforestation projects, energy efficiency in construction, and national support for mass transit are among relatively simpler adjustments that could significantly lower U.S. production of greenhouse gases. More aggressive adjustments include a gradual worldwide shift away from the use of fossil fuels, the elimination of chlorofluorocarbons, and the slowing of deforestation by restructuring the economies of developing nations. In 2002 the Bush administration proposed several voluntary measures for slowing the increase in, instead of reducing, emissions of greenhouses gases.

Answer 2

Yes, it exists. The big question seems to be whether or not human activity (specifically the production of greenhouse gases such as carbon dioxide) is creating the problem, accelerating a natural cycle, or if the change in global climate is entirely natural.

To me, this sounds like arguing about whether or not the fire in your house was deliberately set or an accident rather than actually dealing with the fire.

Natural or man-made, we'll be just as dead.

I'm thinking it's well past time we started actually making plans for what we're going to do when glaciers and ice caps melt, raising ocean levels and inundating the incredibly populous coastal cities we've gone and built all over the map.

We also might want to take a look at what effects it might have on crop production, fishery stocks and other climate dependent processes that we use to feed ourselves. What exactly do we do if droughts and warm weather cause global failures of rice and wheat crops three years in a row?

Disease proliferation is another major concern. Malaria was once common all the way up the Ohio river valley and up into Canada. It won't take much to allow it to spread north again, just a two day extension of the development season that will allow the Plasmodium parasite to conquer North America again. Other diseases could also easily spread with warmer climates.

Sure, it's a good idea to cut down on our greenhouse gas emissions. I don't think anyone rational can possibly argue that their actually doing anyone or anything any good. However, I think it's more important that we start planning on what we're gonna do if things really start to heat up.

Answer 3

We can stop it and we must. The Americans should (this time around) lead the way. At the moment they have taken a back seat and are towing the other way against the EU. They have enough influence and resources to make a real difference. This is not about oil revenues and oil consumption, it is about disruptions of life on earth. Where we live and the options of relocating with all these visa and political boundaries we have created. We need sustainable development i.e. our actions today should not hinder life on earth in two or three hundred years time.

Answer 4

Global Warming is going to ruin this earth for the present humans. It will stop at some point, either because current trends in dumping garabage into our atmosphere changes or we are all destroyed and a new world emerges. The choice is ours!

Answer 5

Personally, I do not believe it exsists. Not in the political sense anyways. It's not what they force down our throats to try and believe. In my personal opinion I'd like to try and give you something to think about. Take a glass of water, make sure a third of the water is solid ice (as cold as you can get) Leave it out for a while. You can even cover it up if you'd like (just to make sure there is no outside interference) Wait.....wait a little more...ok, now check it, What do you know, the ice melted. Guess what....The earth, has ice....ok, right, we're on the same page here right? ok. Over time, that ice is going to melt, regardless of what happens. Even if there was no humans on earth, no machines, no factories...that ice is still going to melt. It happens, its science. There is nothing you can do to stop it. We aren't even the number one cause of the heat either. Not even close to number one for that matter. Even if the world reaches a high average temp (in the 100's at least) It's going to take time. Why worry? It's going to take A LOT of time. That's where evolution comes into play. We'll all be fine.

Answer 6

there have been many global warming and global cooling cycles in the earth's history, we have been in a global warming trend for at least 10,000 years

this trend seems to be accelerating lately due to human activity

it may bring us to our destruction, it may not

it will certainly cause us problems

it may be that Earth created us to warm her surface or to bring unstable fossil fuels to the surface for oxidation, in which case we are serving our purpose

Answer 7

part of it is normal cycle of warming and cooling, but it has been found that there is an increase of CO2 in the atmosphere and a corresponding increase in temperature

Answer 8

I agree. This is just another version of the big lie.

Answer 9

**** global warming i beat the **** out of it when it gets here

Answer 10

well it probally never be fixed so i think we are as screwed as a screwdriver. and for all the non believers. "LOOK OUTSIDE D**KS" like u "shqiptare" and you "bmwgirl" and also "Houston-Norm"
