"So has there been much temperature rise in the oceans ?"

But ocean warming is not uniform: http://www.weather.com/news/science/environment/global-warming-hiatus-tied-pacific-ocean-cooldown-20130829

Acidification may have an impact http://phys.org/news/2013-08-science-global-source-sea.html

Joe, I'm all for thorium nuclear for baseload and renewables for top-up, with renewables taking over the bulk domestic load as technology advances.

A long journey begins with a single step. Let's make sure it's in the right direction. "Direct Action" is a step down a dead-end road, including growing trees, paying industry for efficiencies and whatever other action that does not change people's behaviour.

Come off it Luci. The moment someone starts on this ocean acidification, we know they are a con man, or the dupe of a con man.

The ocean is so alkaline that we could not even bring it anywhere neutral with all the CO2 in the solar system.

You are just laying a huge trap for yourself with this bullsh1t. Even not very well educated people, who may be fooled by the greenhouse gas confidence trick, aren't going to fall for this one

Any downward movement on the Ph scale is described as “acidification” (becoming more acidic), regardless of the starting point.
Between 1751 and 1994 surface ocean pH is estimated to have decreased from approximately 8.25 to 8.14, representing an increase of almost 30% in ion concentration in the world's oceans.
Equally, any upward movement in average atmospheric temperatures is still “warming”, regardless of relative speed of change.
IOW, it is NOT generally agreed that there has been any cooling in the last 17 years. The average rate of atmospheric warming has been slightly lower, while ocean temperatures have continued to rise.
Again, 2010 is the hottest year on record. 9 out the 10 hottest years on record have occurred this century.
This decade is hotter than last decade, and that was hotter than the decade before.
Anyone less than 36 years old has NEVER experienced a cooler year than the long term average.
Allowing for the well documented cooling affect of La Nina events -and comparing apples with apples-, 2012 was a hotter La Nina year than 2011; 2010 was a hotter El Nino year than 1998.
Sea surface temperature increased over the 20th century and continues to rise. From 1901 through 2012, temperatures rose at an average rate of 0.13°F per decade.

Hi Grim,

"Between 1751 and 1994 surface ocean pH is estimated to have decreased from approximately 8.25 to 8.14, representing an increase of almost 30% in ion concentration in the world's oceans."

30 % ? An decrease in pH from 8.25 to 8.14 is a change by 30 % ? I may be one of OLO's village idiots - just ask Poirot - but I really can't get my head around that.

Now: if all that extra heat is being trapped in the oceans, at a great depth, and that warmer water is held down there by currents or upswell-downswell or fairies, it still should be locatable and its temperature measurable ?

So how much have oceans warmed by, in the past magic fifteen years ? And why, fifteen years ago, did the globe 'decide' not to keep heating up the atmosphere but 'decided' to heat up the oceans instead ?

Or does global warming go through some sort of oscillation: warming, cooling, warming cooling.... Or what ?

A fool can ask questions that an 'expert' can't readily answer, I suppose :)

Joe

Ph is a logarithmic scale. One unit change in scale represents a 10 fold change in hydrogen ion concentration.
This is very basic chemistry. If you 'can't get your head around that', why should anyone be interested in your opinions on something as complex as climate change?
Thanks for a great excuse to discontinue this -obviously useless- discourse.

Yes, Loudmouth, you're an amateur who thinks he understands more than he does.

Which is why I usually link to more expert commentary.

It's the only thing to do around here, since most scientists trained in the various disciplines of climate science wouldn't touch this forum with a bargepole.
