I think there is like 5,000 Trillion tons of atmosphere and CO2 is 0.038% of it, so that is 190 Trillion tons of CO2 in our atmosphere. Now it is said in here that we have added 1100 Billion or 1.1 Trillion tons of CO2. So 1.1 Trillion divided by 190 Trillion is roughly 0.5% we have added since the start. This is too simple for most people to grasp. Whoever quoted the 1100 Billion has a good estimate based on estimates from current output; and estimating the amount we have put out and are putting out, is not too hard. So can someone now explain how .5 % added to a GHG that is only a very minor one next to water vapour, could be responsible for warming the planet ?
And, if you are someone who thinks that polar ice is what causes cold fronts, and rain to fall in the Northern Hemisphere please give it up and find someone else to waste your time on. What do you think causes polar ice if the ice is responsible for the cold ? Water vapour primarily comes from the tropics and moves North and falls as rain and snow. Has nothing to do with Polar Ice.
Does anyone know that some polar bears are having trouble finding food because there is too much ice? This climate thing gets rather complicated now. Too little, too much oh what are we going to do ? Maybe life is just tough after all.
