"The oceans act as a "sink" for CO2 and hold 60 times more of it
than does the atmosphere."
That calculation involves quite a large assumption but it is in many way irrelevant.
We have interupted the ice-age cycle.
If you look at how ice ages cycle what occurs is atmospheric CO2 levels rise, causing polar ice to melt, this causes the volume of the sea to increase resulting in increased absorption of CO2, which decreases atmospheric CO2 levels, which causes a decrease in ambient temperature and hence the formation of more polar ice, which decreases the volume of the oceans which increases the amount of atmospheric CO2.......... rinse repeat.
Now instead of the usual decrease in CO2 levels that occurs where we are in the cycle we see an increase,
We have delayed the next ice age but if we keep increasing the amount of CO2 we give out, we will reach the next ice age trigger point, then we will be in trouble.
"And finally, I say to you, our weather forecasters can't even
predict the weather for a few hours ahead of a broadcast with *any*
accuracy-- how do you think _anyone_ can forecast it for the next
centure"
You are mixing two extremely different ideas, accurate local weather predictions are impossible over long periods of time because the weather is chaotic, however large scale climate changes like ice ages etc., follow very repeatable non-chaotic patterns.
