No, the main reason is that the NH is 30% ocean, 70% land, and the SH is 70% ocean and 30% land, and the oceans are warming considerably more slowly than land surfaces. And recently there has been an oceanic shift favoring slightly cooler surface ocean conditions in some regions.
“and the oceans are warming considerably more slowly than land surfaces. And recently there has been an oceanic shift favoring slightly cooler surface ocean conditions in some regions.”
Just create some epicycles in your models to account for the inconvenient facts. That will make everything seem semi-rational.
Seriously, are you one of the people who make a handsome living off the global warming hoax, or do you actually believe in it? Is it your religion? It does seem to be a very popular modern faith.
I think the real reason of this is that there is no such thing as “global temperature”. From a scientific standpoint, can you really get an average temperature from the earth? You run into an infinite boundary when you logically dissect this notion.
The devil is in the details. Climate is not something that can be measured by a thermometer. Think about it. The earth’s atmosphere is better understood today than it has been in our history. But the the fact remains, that we understand more about the interplay between our celestial neighbors in our own solar system than we do about deep ocean currents,the interaction of GHGs in our atmosphere, and know almost nothing about the five bazillion other data sets that make up “climate”.
We may be able to understand what will probably happen in a very precise geographic location in a very restricted time frame and very restricted set of conditions. And even then, we are wrong more than 20% of the time.
You can go on and on for days trying to dissect this absurdity talking about solar winds, recurring weather cycles, non anthropogenic contributors, occean currents and blah de blah de blah. The fact is we know very very little. To think we can draw any reasonable and reliable conclusion about long term climatic trends is just absurd and quite pompous in my own educated opinion. To make policy and restrict modern convenience is mostly suicidal.
The day when they can reverse-test their models, i will listen to them. Until then, its all nonesense being pushed by grant hungry science whores. Albeit sometimes it is dangerous nonesense.
The oceans are not warming.
