because they do not help to reduce the amount of co2 in the atmosphere
the reason is that certain gases, dubbed greenhouse gases by us scientists have the ability to trap heat radiation from the suns rays in our atmosphere, heat that would normally dissipate into the vacuum of space. those gases include methane and carbon dioxide. when in suitable amounts those gases are actually beneficial to life on earth as without them the earth would be far too cold to support any interesting life. unfortunately human activities are releasing huge amounts of said greenhouse gases into the air, meaning that more heat rays are trapped and hey presto, the world heats up
Greenhouse gases help keep the earth's temperature at a comfortable level suitable for human existence. When we increase the atmospheric concentration of greenhouse gases above their natural level, this leads to global warming, in other words higher average temperatures across the globe.
The greenhouse effect is simply the atmosphere's ability to retain heat. This is caused by gases, which we call greenhouse gases. These gases trap heat, rather like greenhouses trap heat to help grow plants in cold climates.
The atmospheric gases carbon dioxide, methane and nitrous oxide are all greenhouse gases that help to heat the Earth.

No help. Greenhouse gases break down the ozone layer and allow harmful UV rays to hit the earth. The planet is getting hotter and we are seeing the results of it now.
A decrease in the amount of greenhouse gases in Earth's atmosphere would result in Cooler global temperatures. This would help decrease the impact of global warming.

Because the "greenhouse gases" act similarly to a greenhouse. The heat goes through the gases (glass panes) and is stored on Earth (greenhouse) and is unable to exit back into the atmosphere (sky). Google "greenhouse effect" and go look at the images, the pictures on the first page will help you to understand my analogy.
Generally, it is radiation from the sun and geothermal energy that warm the planet. Greenhouse gases help regulate the temperature on the surface though. A gas which is important is carbon dioxide. There are others too, such as water vapour and methane.
Greenhouse gases absorb infra red radiation (heat) coming back up from the warmed earth. They hold this heat, and in turn warm up the air around them, as well as warming the earth's surface again.
The greenhouse effect is capturing heat in the atmosphere. It does this with the help of various greenhouse gases, especially carbon dioxide and methane. Because human activities are putting much more of these gases into the atmosphere without any signs of slowing, the atmosphere now has too much heat trapped in it.

the names of green house gases are :- water vapour carbon dioxide methane ozone Any gas with three or more atomes is considered a green house gas. Water vapor makes up about 80% of all green house gas.
Greenhouse gases in the atmosphere help trap heat emitted from the Earth, otherwise the temperature of Earth's surface would be below zero.
There are several gases that are classed as greenhouse gases.They are:water vaporcarbon dioxideozonemethanenitrous oxideCFCsEnergy from the sun heats the earth's surface and atmosphere, which drives the earth's weather and climate. The earth's surface radiates some of this solar energy back into space. These atmospheric gases are called greenhouse gases because they help trap some of the outgoing energy, retaining heat somewhat like the glass panels of a greenhouse.
