Do Green house gasses effect the earths temperatures?

Answer 1

Not really. The green house effect refers to heat trapping gases within the atmosphere. If we were able to reduce concentrations of those gases, we could cool the planet.

50 million years ago there was a fresh water arctic fern called azolla. When it died, it sank to the bottom of the arctic sea. Over a period of several million years this fern dropped global carbon dioxide levels, plunging the earth into its first ice age in eons. We could possibly genetically engineer something of that nature to offset the carbon we've been pumping into the atmosphere. It would be a neat trick if we could pull it off.

Answer 2

well, greenhouse gases are heat-traping gases (such as CO2 and methane)

because they trap heat, the more greenhouse gases in the atmosphere, the more heat is stored in the atmosphere, therefore, over time- it can change the earths climate.

that is not to say that greenhouse gases are not needed. they are naturally occurring, and without their ability to trap these gases, earth would be inhabitable. however, it is now known that the increase in these gases are causing changes, which is why there are attempts at lowering the levels of some of the most influential gases that we put into the atmosphere- most commonly CO2
