So, in summary; probably no net warming for awhile, and maybe a period of extended cooling as in the mid 20th century. It all depends on whether this current PDO shift is a short term or longer term event such as we saw in the mid 20th century.

This is inline with the article in today’s UK Telegraph, saying:

“Global warming will stop until at least 2015 because of natural variations in the climate, scientists have said. Researchers studying long-term changes in sea temperatures said they now expect a “lull” for up to a decade while natural variations in climate cancel out the increases caused by man-made greenhouse gas emissions.

The average temperature of the sea around Europe and North America is expected to cool slightly over the decade while the tropical Pacific remains unchanged. This would mean that the 0.3°C global average temperature rise which has been predicted for the next decade by the UN’s Intergovernmental Panel on Climate Change may not happen, according to the paper published in the scientific journal Nature.”

That’s not what Al Gore said.
