Petition: Investigate NOAA impartially
No Whitewash!

Friend,

Did government researchers at the National Oceanic and Atmospheric Administration tamper with temperature data to boost the global warming campaign?

Dr. John Bates, a climate scientist and former official with NOAA, says they did.

This needs to be fully investigated, but we must not allow climate campaigners to turn this investigation into an exercise in whitewashing.

CFACT is petitioning President Trump to ensure the people investigating NOAA are genuine, impartial outsiders.

Please sign this important petition today and forward it to as many friends as possible.

The climate campaign will use its influence to whitewash improper practices at NOAA, but only if we let them.

Sign the petition and tell the President to find out what’s really been going on at NOAA.
For nature and people too,

 

Craig Rucker
Executive Director &
Co-Founder

Oh, darn! Declining Arctic sea ice influences European weather — but isn’t a cause of colder winters

Oh, darn! Declining Arctic sea ice influences European weather — but isn’t a cause of colder winters

via Watts Up With That?http://ift.tt/1Viafi3

From the UNIVERSITY OF EXETER and the “department of dashed alarm hopes”, comes this surprising study, but alas, it’s just another model, so take it with a grain of salt.

Declining Arctic sea ice influences European weather — but isn’t a cause of colder winters

The dramatic loss of Arctic sea ice through climate change is unlikely to lead to more severe winter weather across Northern Europe, new research has shown.

A pioneering new study has explored how Arctic sea-ice loss influences the North Atlantic Oscillation (NAO) weather phenomenon, which affects winter weather conditions in Northern Europe, in places such as the UK, Scandinavia and the Baltic states.

Previous studies have suggested that Arctic sea-ice loss causes the NAO to spend longer in its ‘negative phase’ – generating more easterly winds that bring colder air from Scandinavia and Siberia to the UK. This might be expected to cause more frequent cold winters, such as the deep freeze experienced in the UK in the winter of 2009/2010.

However the new study, carried out by Dr James Screen from the University of Exeter, crucially suggests that Arctic sea-ice loss does not cause colder European winters.

Dr Screen suggests this surprising result is due to a ‘missing’ cooling response – meaning that the expected cooling brought about by more easterly winds is offset by the widespread warming effects of Arctic sea-ice loss.

The study is published in leading science journal, Nature Communications.

Dr Screen, a Senior Lecturer in Mathematics at the University of Exeter said:

“We know that the NAO is an important factor in controlling winter weather over Northern Europe”.

“The negative phase of the NAO is typically associated with colder winters. Because of this it has been reasonable to think that we would experience more severe winter weather if Arctic sea-ice loss intensifies the negative phase of the NAO”.

“This research indicates that although sea-ice loss does intensify the negative NAO, bringing more days of cold easterly winds, it also causes those same winds to be warmer than they used to be. These two competing effects cancel each other out, meaning little change in the average temperature of European winters as a consequence of sea-ice loss”.

The NAO phenomenon describes large-scale changes in atmospheric wind patterns over the North Atlantic. Importantly, the NAO relates to changes in the strength and position of the North Atlantic jet stream – a band of very fast winds high in the atmosphere. The position of the jet stream has a substantial impact on weather in Northern Europe.

Using the sophisticated UK Met Office climate model, Dr Screen conducted computer experiments to study the effects of Arctic sea-ice loss on the NAO and on Northern European winter temperatures.

Dr Screen added:

“Scientists are eager to understand the far-flung effects of Arctic sea-ice loss. On the one hand this study shows that sea-ice loss does influence European wind patterns. But on the other hand, Arctic sea-ice loss does not appear to be a cause of European temperature change, as some scientists have argued.”

Never Mind The Area, Feel The Thickness

Never Mind The Area, Feel The Thickness

For years, discussion of Arctic sea ice has revolved around extent. Indeed NSIDC’s regular monthly Arctic Sea Ice News talks about little else, particularly when there is an unusually low figure.

However, when extents are not so unusually low, the Arctic obsessives switch the goal posts to thickness/volume.

There is one problem however – there is no reliable measurement data around to track it.

 

As the Greenpeace activist, and part time NSIDC scientist, Julienne Stroeve admitted, “satellite measurements [of thickness] are not continuous in time, not continuous in space.” (See BBC interview at 4 mins in here).

To get around this slight problem, the obsessives turn to the PIOMAS Arctic Sea Ice Volume Reanalysis, shown above.

But this is not based on real data, though they seem to delude themselves that it does. Instead, it is a numerical model with components for sea ice and ocean and the capacity for assimilating some kinds of observation.

Or as someone put it, a model to estimate what area and thickness would have been elsewhere had we measured them.

 

Now PIOMAS might have its uses, and it may have some relation to reality. But we need to see what the PIOMAS team themselves say about its accuracy:

 

PIOMAS has been extensively validated through comparisons with observations from US-Navy submarines, oceanographic moorings, and satellites. In addition model runs were performed in which model parameters and assimilation procedures were altered.  From these validation studies we arrive at conservative estimates of the uncertainty in the trend of  ± 1.0 103 km3/decade. The uncertainty of the  monthly averaged ice volume anomaly is estimated as ±0.75  103 km3. Total volume uncertainties are larger than those for the anomaly because model biases are removed when calculating the anomalies. The uncertainty for October total ice volume is estimated to be  ±1.35 103 km3

Last October’s ice volume was 5500 cu km, so the uncertainty is a massive 25%.

It is hard to see how any significance can be read into recent trends, when error margins are so large, even assuming the model is reliable in the first place.
