To the above I could reiterate the economist's caveat: Correlation oes not
necessarily imply causation. In any case my understanding is that the CO2
concentration lags the temperature, so why don't we say that increasing
temperature has resulted in release of CO2 from the oceans?

It would be better to reread Glenn's blog than to rely on my explanation.
However, in explanation Glenn postulated that October is a month when air
conditioners are shut down, so the surface stations located near air
conditioner exhausts are registering the true temperature. There are a lot
of surface stations located near air conditioner exhausts, as you will find
from looking at

The same criticism can be leveled at the AGW advocates. When they are
advocating the expenditure of trillions of dollars to alleviate a condition
that does not show up uniformly, and when it is suspected by some that they
have cooked their data, they should be willing to respond to criticisms.
