SHOULD WE USE THE RAW DATA? We are familiar with the land temperature data,?

But the adjusted data for the ocean, and thus for the total globe shows LESS warming than the raw data. That is right, raw data shows MORE warming.

No, use the adjusted data, because it is the best estimate after correction for errors.
But note that over land and sea, overall, the supposedly "biased" scientists use LESS global warming than the raw data. If AGW is a hoax, I would have expected them to make the data show MORE warming.
