Global warming slowdown 'could last another decade'

The hiatus in the rise in global temperatures could last for another 10 years, according to new research.

Scientists have struggled to explain the so-called pause that began in 1999, despite ever increasing levels of CO2 in the atmosphere.

The latest theory says that a naturally occurring 30-year cycle in the Atlantic Ocean is behind the slowdown.

The researchers says this slow-moving current could continue to divert heat into the deep seas for another decade.

However, they caution that global temperatures are likely to increase rapidly when the cycle flips to a warmer phase.

According to the Intergovernmental Panel on Climate Change (IPCC), global average temperatures have increased by around 0.05C per decade in the period between 1998 and 2012.

This compares with a decadal average of 0.12 between 1951 and 2012.

More than a dozen theories have been put forward on the cause of this pause in temperature growth that occurred while emissions of carbon dioxide were at record highs.

Whatever happened to all the climate refugees?

A couple of hydrogen bombs ought to calm Big Red down! /s;)

OK, I'll repost. ;-)

Incidentally, the umm, article which is the subject of this thread, gives a whole new meaning to the phrase "Hide the decline" doesn't it?

Cheers!

Umm, water below 39 degrees F or so, *is* less dense than slightly warmer water. It has to do with hydrogen bonding, and is why ice floats.

Of course, I don't think that's quite what they had in mind... Cheers!

The planet is 5 billion years old. We have reliable weather records for, oh let’s be generous- 150 years. trying to tell what the weather will be like in the future with that dataset is like trying to figure out what will happen all of next month by figuring what happened just last tuesday at 6:32 Pm and 20 seconds ONLY.

True enough!

That general issue did come to mind after I made my original post.

But, when contemplating whether that’s relevant or not the question “What percentage of the world’s oceans have a surface temperature below 39F and for what percentage of the year?” has to be answered.

This new excuse is based on condition that warm water sinks.

“The researchers says this slow-moving current could continue to divert heat into the deep seas for another decade.”

Secondly, with the west-to-east weather in the northern hemisphere the Atlantic current does not affect US temperatures. So US land temperatures should not reflect the Atlantic’s ‘sinking warm water’.

Most of all they’re mum on the upper-atmospheric temperature readings which, coincidentally, are also lower.

So they’re just grasping at whatever they can to rationalize lower temperatures within their AGW modeling.

They’re crooks and should be subject to civil and criminal prosecution for dishonesty.

Computer modeling is their gold mine. They can always claim their models were wrong rather admit they were wrong and lied. It provides them cover for scientific and professional dishonesty.

I hope not, but unfortunately it does.

The BIGGEST determinator of global warming is the Pacific thermocline.

And, AFAIK, it has changed little (maybe 7 feet) since 1900.
