How much is earth emitting and how much can earth absorb. Without this important detail then it's worthless making assumptions.
But much more importantly we have no idea what effect it will have, but the chances are that it will not affect is in any major way.
Climate is clearly extremely complex system with lot of built in feedbacks which make small changes in something able to cause big unpredictable changes in the end. (chaos theory was born from climate study)
Change in ocean currents/weather patterns could cause formation of more ice and snow leading to negative feedback...
Melting of ice sheets again lowers Earth's albedo meaning more of suns energy is absorbed causing positive feedback...
Warm arctic enough and you suddenly have massive increase in methane (much stronger greenhouse gas) concentration...
Disturb oceans enough and methane hydrates might release their methane to atmosphere...
Also particle emissions block some sunlight from getting to surface so full effects of CO2 increase might be masked by them...
So you're basically saying that it's safe to point handgun to own head and start pulling trigger without having no idea is there cartridge in chamber and when trigger would release hammer.
Only major wrong thing is name, it should be global climate disturbance.
Do you have any idea what the sensitivity and resolution of the vostok ice core data is... Here's a hint, previous short term spikes like this one (say several hundred years) simply wouldn't show up in it....
One of the few possible source for that level fast CO2 concentration jumps would be massive volcanic activity or something equally major which would have significant effects to planet.
But no geological evidence of anything such and massive volcanic activity would leave its other signs to ice cores.
Of course ice layers in cores don't come with year sticker and from this data it's impossible to tell which one is causing which effect but it's extremely clear that changes in temperature and CO2 concentration are closely related.
Anyone else having "
SMOCE and SPIL" stocks under his pillow?
Or are you trying to be evidence for that human could survive bullet through head because there's "nothing critical for operation" in there?
