Could the cause of global warming be ocean water temperature rising?
It is a very real possibility. Why? Because ...
I have not (yet) found evidence of atmospheric warming over Canada (see here).
My research forces me to conclude that we cannot be experiencing "global" warming ... if Canada has somehow been spared!
In fact, I have found that the atmosphere has actually grown cooler over Canada! (see here).
To better understand how the atmosphere works, and its interaction with the earth's surface and oceans, I highly recommend...
What If ...
So. What if there is no global atmospheric warming? Instead, what if we are experiencing a global ocean warming?
Could it be that the phenomena we are observing ...
... are the direct result of sea surface temperature rising?
Ocean Temperature Graphs
The two sea surface temperature charts below clearly show that the Pacific Ocean water temperature was warmer, from the mid twenties to the mid forties and, again, warmer since the seventies!
The Pacific Decadal Oscillation (PDO) Index is defined as the leading principal component of North Pacific monthly sea surface temperature variability.
Quoting the JISAO (Joint Institute for the Study of the Atmosphere and Ocean):
What To Conclude?
We can see on the graphs that the Pacific Ocean temperature rose, and has only just begun to cool back down in recent years.
That would explain the warmer temperatures I found on Canada's Pacific west coast, in my recent research (see here). Port Hardy, British Columbia (and most other stations on the west coast), have reported a distinct warming trend that began in the seventies.
Further Investigation Required
It all began when I could not find evidence of global atmospheric warming over Canada. Then I discovered that the world's scientific community was torn in half on, whether or not, there is global atmospheric warming!
So, after my two first studies, I decided to change course. Instead of looking for the cause of global warming, I began looking for the cause behind some of the climatic changes that have been observed in parts of Canada.
That is how I stumbled on the above research results on the Pacific Ocean temperature. Interesting, to say the least.
But, what has caused the Pacific Ocean waters to warm up?
That is the question ... that the scientific community is still trying to answer!
This important find has had an impact on the efforts to find the cause of global warming.
Keep a sharp weather watch and an open mind.
