“What may be” are the key words here...since they indicate that it may NOT be as well. Will be is one thing; maybe is quite another.
The ocean cannot warm the atmosphere without cooling itself.
So are the Paris accords going to address the PDO? When El Nino goes away this Summer watch the temperatures start to go sown. What percentage of Scientists attribute GW to the PDO? Notice that the article admits to the 15 tear lull in GW.
You have been pinged because of your interest in environmentalism, alarmist wackos, mainstream media doomsday hype, and other issues pertaining to global warming.

Great point.
I love when writers prove they know nothing by statements like that. The reason that negative PDO is called "cool" is it results in temporarily cooler temperatures in much of North America. But there are two other things negative PDO causes:
1. Global warming (for the most part)
2. Large amounts of heat transferred through the Bering Strait and via teleconnections into the Arctic where it melts the ice.
Since we have seen only modest warming, we can pretty much say that manmade warming is pretty minor since there was also potential added warming from negative PDO to some unknowable extent.
The important thing to remember is that the effects are not linear or constant. At first negative PDO delivers some global cooling. But that turns into global warming over the longer run of negative PDO. The reason is pictured above, mainly surface warming effects for the planet as a whole.
Anecdotes mean very little. In my area, we are at record heat levels. We are hitting the 80's this week. It hasn't been this warm here at this time of year, definitely warmer than usual. Does this have anything to do with AGW? Maybe not, but anecdotes in either direction dont mean anything.
