100% of deforestation affects the environment in some ways, whether it is the destruction of native animals' habitats, or the loss of carbon sinks, or the removal of roots and shrubbery that binds the topsoil.

What percentage of green house gases come from deforestation globally?
15%
What reasons are various countries reluctant to make firm commitments to make deep reductions in greenhouse gases?
They believe reducing greenhouse gases will reduce the standard of living in their countries.Most of the emissions come from just a few rich nations.They believe reducing greenhouse gases will not make a difference on climate change.
What are four changes that come from the greenhouse effect?
Additional gases are causing an enhanced (or accelerated) greenhouse effect which is causing global warming.Glaciers and ice caps are melting.Sea levels are rising.Storms are becoming more violent and destructive.
Why does the greenhouse effect cause warmer temperatures near the surface of earth?
The greenhouse gases are in the troposphere, that's the lowest layer of the atmosphere. The sun's rays come in and warm the earth. The warm earth then radiates infrared heat, some of which is trapped by greenhouse gases in the lower atmosphere. These greenhouse gases (water vapor, carbon dioxide, methane, nitrous oxide and CFCs) warm up. They in turn radiate their warmth and some of it goes down again and warms the earth's surface. The heat can continue going up and down like that.
Why are greenhouse gases similar to a Greenhouse?
Like in a greenhouse, greenhouse gasses let radiation from the sun reach Earth (the 'inside' of the greenhouse) but won't let the Earth reflect radiation. This is exactly what greenhouses do. Through the glass walls, the sunlight can come in, but once the rays are inside, the heat is trapped. That causes (intentional) temperature rise in the greenhouse. These gasses also (most likely) cause a temperature rise on Earth.
What is the primary transportation related greenhouse gas?
Electricity generation from coal fired power plants produces the most greenhouse gas. The US & China consume about 2.5 billion tons of coal per year. Gas and diesel engines used in transportation come in a pretty close second.
What are greenhouse gases and where do they come from?
Greenhouse gases are gases which trap infrared radiation from clouds and from the warm earth. Examples are carbon dioxide, and methane. Carbon dioxide occurs naturally through the carbon cycle but it is also now being added by burning fossil fuels and from deforestation, where trees no longer absorb and store the carbon. Methane comes from melting swamps, tundra and lakes, as well as from cattle farming.
Why does the production of carbon dioxide and other greenhouse gases on Earth cause a rise in global temperature?
because its burns off the ozone layers and more of the sun's rays come through.
How much pollution does methane produce?
According to the US Environmental Protection Agency, over 60% of methane emissions come from human activities. The remaining 40% is emitted from other sources such as wetlands, where bacteria decomposes organic materials in anaerobic conditions (oxygen free). Other sources of methane release include termites, oceans, sediments, volcanoes, and wildfires. Carbon dioxide is the main contributor to greenhouse gases, and makes up about two thirds of greenhouse gases produced by human activities. However, weight for weight the contribution of methane to greenhouse gases is comparatively 21 times greater than carbon dioxide over a 100 year period. So although methane 'pollution' is relatively low it is amongst the worst of greenhouse gases.
Where do the gases come from in the acid rain?
the gases come from factories
Where do these main gases come from?
they come from earths atmosphere and gases
How do greenhouse gases modify Earth's temperatures?
If you want to see an example of the greenhouse effect, just go to Venus! (Atmosphere of Venus: 96.5% carbon dioxide. Temperature of Venus: 467°C (872°F))To answer your question, when rays of the sun come through our atmosphere they heat the land, water and such. This heat then radiates out from the warmed earth. Some of the goes back through the atmosphere and out into space, but the greenhouse gases capture and retain some of this heat. This is the natural greenhouse effect that keeps the planet warm. Any extra greenhouse gases (from man's activities of burning fossil fuels and deforestation) are too much for the natural carbon cycle to remove, so they absorb extra reflected heat. This is what is causing global warming.Answer:The popular view is that the atmosphere has some sort of layer of carbon dioxide "up there" that reflects heat back down to Earth rather than letting it escape to space. That would be like the glass on a greenhouse trapping warm air in while letting the sunlight through to increase the heat. In a greenhouse the sunlight warms the benches and floor, he warm objects heat the air, the air is trapped by the double layer of insulating glass.It does not happen that way in our atmosphere.Sunlight comes in and warms the Earth's surface. It warms the gases in the air too, at least some of them with a bond size that gets excited by sunlight. These special gases are greenhouse gases (carbon dioxide, methane, water vapour and a few others). They are mixed evenly through all of the atmosphere (not in layer). When the gases are warm they share their heat with all their gas molecule neighbour and heat the atmosphere generally.The effect i more like wet sand in a microwave. Microwaves do not heat sand. They do heat water. When you microwave wet sand, the water heats up - might even turn to steam. The hot water warms the sand.
