Does carbon dating work? And why? Does time, temp, pressure change states? Other elements?
(This is to the above posts prior to this, croc covered this subject pretty well.)
CO2 doesn't dissapate in the ice. It remains trapped for as ong as it takes in air pockets.
Methane dissapates quickly in the atmosphere, not CO2, which takes much longer to be removed from the atmosphere. It is absorbed by the oceans (which acidifies the oceans) but the oceans can only absorb so much.
It doesn't leach out of the air pockets in the ice so that point is mute
Wow. Deforestation is bollocks? Thats a big thing to say. I hope you have masses of evidence that it is. Enough to counter all the evidence that deforestation is not bollocks.
The cows are contributing to this, but that more to do with what they eat. Buffalos (and indeed wild cattle) do not eat the same things and as such there methane release is a lot lower.
There would be a large transitional change from boreal to coniferous forests. Most deciduous trees take decades to grow to the size if the conifers it would replace.
Other (wild) plants do not take place, crops do, crops absorb less CO2 per acre than forest and in the rainforest not only is the forest burnt clear (releasing stored CO2) and then there is only 2 or 3 growing seasons, before they realise that rainforest soil is actually appalling for crop growth and have to abandon it (by clearing the forests again). Now the soil is devoid of nutrients and useless for healthy plant growth.
