How could increases in the carbon dioxide in the air affect world temperatures?

Answer 1

Carbon dioxide raises Earth's temperature because it is a greenhouse gas. The greenhouse effect is basically when gases, like carbon dioxide, trap in heat from the sun that would usually be released back into space. Too many of these greenhouse gases traps in too much heat, which then creates problems like melting glaciers and even effects the migration of animals. But without these gases the Earth wouldn't be able to retain any heat so it wouldn't be suitable for life, therefore it is important to maintain a certain amount of greenhouse gases in the atmosphere.

A:Due to carbon dioxide sunlight get trapped in earth's atmosphere, increases the temperature and results in global warming. Due to this glaciers melt and sea level increases and hence coastal areas may flood. A:The sun's rays reach us in the form of visible light, and raise the temperature of earth. This heat energy warms the earth then goes back into space, and so the temperature remains in balance.

When we burn fossil fuels for electricity and transport, much more CO2 is produced in the atmosphere. About half of it is utilized by plants and the carbon dioxide remaining goes on accumulating in the lower areas of atmosphere, forming a thick dense layer of greenhouse gas.

This thick layer slows down the re-radiation of heat energy back to the space and adds more temperature to the surface of earth.

This additional warming of the earth's surface is called the enhanced greenhouse effect and is responsible for global warming.

Answer 2

CO2 is transparent to "visible light" (sunlight), but opaque to infra-red (heat radiation).

Thus heat gets in from the sun normally, but is retarded when it is time to re-radiate it back into space (at night).

Answer 3

it contributes as co2 traps heat and makes the environment warmer.

Answer 4

Carbon dioxide traps heat in the Earth's atmosphere, causing global temperatures to rise.
