Are methane emissions responsible for the greenhouse effect?

Answer 1

Greenhouse gases trap heat in the atmosphere.

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, the warm objects heat the air, the air is trapped by the double layer of insulating glass.

It does not happen that way.

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 layers). When the gases are warm they share their heat with all their gas molecule neighbours and heat the atmosphere generally.

The effect is 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.

Answer 2

That is true. Carbon dioxide (CO2), specifically the CO2 released by burning fossil fuels, and methane from ruminant animals and melting tundra are contributing to climate change.

Answer 3

Almost all of the greenhouse effect is due to water vapor. Even when dealing with the theory of man induced warming, water vapor is used to create the predicted affects. Water vapor makes up about 75% of the total effect.

Answer 4

The carbon and water cycles of the earth are responsible for the normal greenhouse effect which keeps the earth warm enough for life. The greenhouse gases, including carbon dioxide, capture and hold some of the heat being radiated out to space.

Carbon dioxide (from burning fossil fuels) as well as deforestation is largely responsible for the enhancedgreenhouse effect that is causing Global Warming and leading to climate change.

Answer 5

Partly responsible. The main greenhouse gas causing accelerated greenhouse effect and global warming is carbon dioxide. Methane is produced in lesser amounts, from the belchings of cattle, and also from anaerobic degradation of manure. It is also released from melting tundra and frozen lakes, so as the world warms, more methane will be released. Methane is a greenhouse gas twenty-one times more powerful than carbon dioxide.

Answer 6

Greenhouse Gases:

•Ozone

•Methane

•Carbon Dioxide

•(Others)

These gases are B-A-D, BAD. They are contributing to global warming and climate change when we drive gasoline cars, we smoke, or we open a heat-filled room and expose it to open cold outdoor air.

Answer 7

Yes. The reason why we encounter global warming is because of the increase in the "thickness" of the greenhouse gas. The main purpose of the greenhouse gas is to trap heat from the sun so that the Earth is at a suitable temperature. Due to pollution and human-made causes, the thickness of the greenhouse gas is increasing.

With the increasing thickness of greenhouse gas, the heat being trapped also increases. Therefore, the Earth is getting warmer and global warming is occurring.

Answer 8

Yes, both methane and carbon dioxide are greenhouse gases. Methane cause more global warming per molecule then carbon dioxide does.

Answer 9

Carbon dioxide and methane are both greenhouse gasses, along with many, many more times of water vapor.
