«That's the other remarkable thing about this research,» said Osterberg, «not only are we seeing strong agreement
between the two Denali cores, we are finding the same story of intensified
storminess recorded in ice cores collected 13 years and 400 miles apart.»
If it is true, as some studies suggest for example, that El Nino events become more frequent and greater in magnitude due to anthropogenic forcing (this is not yet a settled issue), then, given the established relationship
between the El Nino / Southern Oscillation (ENSO) and the extratropical Pacific / North American atmospheric circulation, we might expect increased baroclinicity and greater
storminess over a substantial region of the mid-latitude North Pacific ocean and neighboring western U.S..
The missing sea ice
between Russia and Alaska has also brought unusual
storminess and low pressure to the region during November and December.
There is also low confidence for a clear trend in
storminess proxies over the last century due to inconsistencies
between studies or lack of long - term data in some parts of the world (particularly in the SH).
A possible connection
between cosmic rays and clouds was already established at the end of the 19th century by the inventor of the cloud chamber, Wilson (1899); it was admittedly «speculation» that ionization in the upper troposphere affected
storminess.
As MIT Emeritus Professor Richard Lindzen has explained, the decline in
storminess is a consequence of reduced temperature differentials
between the tropics and exo - tropics that arise when global average temperatures are warmer.
