This is a surface temps anomaly chart, compared to "mean values" for this time of the year and latitude... so I think it just shows areas colder and warmer than expected (deviation). One question I have -to whoever better knows- is whether these Large areas or warmer waters in the North Atlantic could be explained by a weak and late hurricane season so far? Could that mean a wetter automn in NH as colder air builds up and expand next months ahead? (I wonder)

There are no rise in global temperatures...it's going down

Right. So now more and more evidence is coming in that Arctic warming is real!

Artic Warming + Antartic Cooling = Global Cooling?

Artic Warming + Antartic Cooling = Global Cooling? Yes Karlox, unless you believe that the heat jumps 700 meters to deep water, that the temp hasn't been measured in.

So now we are supposed to believe you have not been an advocate for northern hemisphere cooling for years and now you are happy to embrace the USA is getting hotter story! And if I point out how funny that is I have a problem with maths! As ever you can be relied upon to obfuscate and cause trouble and twist and turn regardless of facts or reason

Take a deep breath.....and try again. You aren't making any sense.

I was trying to make it simple -if only for my level- and was just saying that -perhaps- a warmer Artic but cooler Antartica might be a clear sign of mean global cooling. I also have questions like whether HEAT entering the Artic is more likely-easily radiated to space given the characteristics of the tropopause wi Polar Circles closer to the poles, and placement-displacement of Polar Vortex themselves. That is a simple lay-man question I have...

Some advice for Andrew: Please engage brain before opening mouth.

Ratty: Dang if I know about the USA getting hotter. When did that start?

The Arctic is not the Northern Hemisphere and what is "the USA is getting hotter" story? Some advice for Andrew: Please engage brain before opening mouth. Right. A warmer arctic for perhaps thousands of years but North America cannot be getting warmer? I thought it was a proven fact on this board that the USA was not getting warmer, warming was all lies, and it is a proven fact it was warmer a few decades ago? I must have got muddled up though, because now Arctic warming is the new cooling. It sounds just like the AGW crowd where cooling is always warming.

www.wsl.ch/fe/landschaftsdynamik/dendroclimatology/Publikationen/Esper_etal.2012_GPCPalaeoclimatic evidence revealed synchronous temperature variations among Northern Hemisphere regions over the past millennium. The range of these variations (in degrees Celsius) is, however, largely unknown. We here present a 2000-year summer temperature reconstruction from northern Scandinavia and compare this timeseries with existing proxy records to assess the range of reconstructed temperatures at a regional scale. The new reconstruction is based on 578 maximum latewood density pro fi les from living and sub-fossil Pinus sylvestris samples from northern Sweden and Finland. The record provides evidence for sub- stantial warmth during Roman and Medieval times, larger in extent and longer in duration than 20th century warmth. The fi rst century AD was the warmest 100-year period (+0.60 °C on average relative to the 1951 – 1980 mean) of the Common Era, more than 1 °C warmer than the coldest 14th century AD ( ? 0.51 °C). The warmest and coldest reconstructed 30-year periods (AD 21 – 50=+1.05 °C, and AD 1451 – 80= ? 1.19 °C) differ by more than 2 °C, and the range between the fi ve warmest and coldest recon- structed summers in the context of the past 2000 years is estimated to exceed 5 °C. Comparison of the new timeseries with fi ve existing tree-ring based reconstructions from northern Scandinavia revealed synchro- nized climate fl uctuations but substantially different absolute temperatures. Level offset among the various reconstructions in extremely cold and warm years (up to 3 °C) and cold and warm 30-year periods (up to 1.5 °C) are in the order of the total temperature variance of each individual reconstruction over the past 1500 to 2000 years. These fi ndings demonstrate our poor understanding of the absolute temperature vari- ance in a region where high-resolution proxy coverage is denser than in any other area of the world

A warmer arctic for perhaps thousands of years but North America cannot be getting warmer? A warmer Arctic for perhaps thousands of years that is now cooling? Is that what you are talking about Andrew? I am still lost. Oh.......and a hint..... North America is getting colder! At least for the past 150 years.

Ah i see, its the glaciation bi-polar seesaw theory where the Arctic had already warmed and now it is getting colder and the whole of the NH and SH is already heading into glaciation. Silly me.
