BTW you guys have had as cold or worse before.
In your case this is something like the third or forth year straight of record highs for summer. It could be part of a long term tend, or. As you say it could just be a spot of warm weather. Only way to tell is to wait for next summer and see if the weathercontinues to get warmer or for it to get cooler and break the trend

In our case this could just be a random cold snap, but if next winter and the winter after that are as cold or colder then we have a trend. The thing to really watch for is if such trends last more than five to ten years, which would be firm evidence of climate change.

A professional gardener told me recently that our gardening zone has shifted from a 7b to an 8a but it isn't really being talked about ...

Chard we've had droughts of 15 years or more... it aint unusual.

OH BTW a global warming trend is not a cooling trend.... that's heading for an Ice Age...

It is warmer in Alaska this winter than Atlanta. That ain't normal.

So the Polar thingy jumped over Alaska eh?
Mind you weather is not the same thing as climate AIA.
Apparently the highest recorded temp for Alaska was back in 1915.

Now the story moves on. Where does all that head go. There is going to be a long term effect. To those that think we should do nothing.... what is the contingency plan when the energy in the ocean starts to re-emit of it reaches it's capacity.

Do we continue do SFA when the evidence is growing that we are building up a energy/heat time bomb. What a fucking stupid species (colectively) we are.

....They add that the warm water won’t hide below the surface forever.....

Global warming hasn’t stopped, the heat’s just HIDING deep within the Pacific Ocean, claim scientists
IPCC report last year said temperatures have barely risen in past 15 years
This is despite more greenhouse gases being pumped into atmosphere
New study claims winds in Pacific have driven heat deep underwater

This has had a net effect of cooling surface temperatures by 0.1°C and 0.2°C


Read more here as the full article has many graphics: http://www.dailymail.co.uk/sciencetech/ ... z2szrCW2Tf

Powerful winds in the Pacific Ocean, which have driven surface heat deep underwater, could be the reason behind the current ‘pause’ in global warming.

This is according to a joint Australian and U.S. study which has looked at why there has been a slowdown in the planet’s global average surface temperature over the past decade.

Their research shows that trade winds in central and eastern parts of the Pacific have caused warm surface water to sink to the ocean's depths, reducing the amount of heat in the atmosphere.

This is despite the fact concentrations of CO2 and other greenhouse gases in the atmosphere have increased to levels that are unprecedented in at least 800,000 years

The latest study, published in the journal Nature Climate Change, said stronger Pacific trade winds- had made ocean circulation at the Equator speed up.

Colour shading shows observed temperature trends (°C per decade) during 1992-2011 at the sea surface. The bold and thin arrows show an overall acceleration of the Pacific Ocean moving warm, surface waters (indicated by the blue arrow) to below 700 metres beneath the surface
....
The IPCC does not expect the hiatus to last and has said temperatures from 2016-35 were likely to be 0.3-0.7°C warmer than in 1986-2005.

‘More than 93 per cent of the warming of the planet since 1970 is found in the ocean,’ said Steve Rintoul at Australia's CSIRO Marine and Atmospheric Research and lead author of the chapter on oceans in the IPCC's latest climate report.

‘If we want to understand and track the evolution of climate change we need to look in the oceans. The oceans have continued to warm unabated, even during the recent 'hiatus' in warming of surface temperature.’

Climate scientists say such pauses in warming occur regularly throughout history and can last for up to 20 years – but cannot be predicted.

They add that the warm water won’t hide below the surface forever. Scientists believe that it may re-emerge later or affect other climate indicators, such as sea level or ocean circulation.

No.

It's part of the way the planet deals with energy increases. It is more complex than we thought. The oceans are acting like a heat sink. When it cannot absorb anymore, in 20 years or so we will see the heating on the surface accelerate....

Yes... it isn't new knowledge, it's not more complex than we thought... the oceans have always acted like a heat sink, etc, etc, etc.

2009...

http://www.abc.net.au/unleashed/29320.html
Today the Australian Senate voted on the government's Carbon Pollution Reduction Scheme. Even the name of this bill should have rung warning bells as carbon is the foundation of life and is not a pollutant.
It is claimed that there is a scientific consensus about human-induced climate change. There is no consensus and consensus is a process of politics not science. Science is married to evidence no matter how uncomfortable.
At present, atmospheric temperature is decreasing and CO2 is increasing again showing that CO2 is not the principal driver of climate change. Planet Earth is a warm wet greenhouse volcanic planet. The planet is dynamic, change is normal.
Five of the six major ice ages occurred when the atmospheric CO2 content was up to 1,000 times higher than at present and for half of Earth history CO2 has been sequestered naturally into algal reefs, coral reefs, sediments, altered rocks, bacteria, plants, soils and oceans. This process is still taking place.

The hypothesis that high atmospheric CO2 drives global warming is therefore invalid. The Earth's atmospheric CO2 initially derived from volcanic degassing. Much of it still does and the rest is recycled CO2 from the oceans, rocks and life.
Another claim is that climate cannot be reversed. This invokes a non-dynamic planet. The fact that previous warmings with an atmospheric temperature some five degrees Celcius higher than now (eg Minoan, Roman, Medieval) were reversed is conveniently ignored as are the great climate cycles driven by the Sun, the Earth's orbit, tectonics and tides seen on modern, archaeological and geological time scales.

'Tipping points' are another sensationalist unsubstantiated claim. In past times when atmospheric CO2 and temperature were far higher, there were no tipping points, climate disasters or runaway greenhouse. The climate catastrophists attempt to create fear by mentioning the carbon cycle but just happen to omit that significant oxygenation of the atmosphere took place when the planet was in middle age and this process of photosynthesis resulted the recycling and sequestration of carbon.
The fear mongering suggestion that oceans will become acid is also misleading. The oceans are buffered by sediments and volcanic rocks on the sea floor and even in past times when atmospheric temperature and CO2 were far higher than at present, there were no acid oceans. If there had been, there would be no fossils with calcium carbonate shells.
