The State of the Climate November 2015 report noted that in order for 2015 to not become the
warmest year in the 136 - year period of record, the December
global temperature would have to be at least 0.81 °C (1.46 °F) below the 20th century average — or 0.24 °C (0.43 °F)
colder than the
current record low December temperature of 1916.
If in practice a
warmer (less
cold) Arctic coincides with cooling in the world's main population centres (NE USA, NW Europe, N India, N China), as appears to have happened in the early part of the
current NH winter, it is not clear to me why a
warming Arctic should be cause for AGW alarm (although it could perhaps in a crude / tabloid sense be used as cause for
Global Cooling alarm).
Ocean oscillations and
currents could (and do) cause local effects as
warm and
cold water interchanges, but they can not cause a
global effect as they just move energy around rather than increasing it.
In a recent CNN panel debate,
global warming critic Marc Morano of Climate Depot responded to a question suggesting that
current record
cold temperatures are a harbinger of «climate change.»

leading scientist has hit out at misleading newspaper reports that linked his research to claims that the
current cold weather undermines the scientific case for manmade
global warming.
Current global climate models suggest that the water vapor feedback to
global warming due to carbon dioxide increases is weak but these models do not fully resolve the tropopause or the
cold point, nor do they completely represent the QBO [Quasi Biennial Oscillation], deep convective transport and its linkages to SSTs, or the impact of aerosol heating on water input to the stratosphere.
That envelope is not just a matter of
global - average surface temperature (to which the misleadingly innocuous term «
global warming» applies) but of averages and extremes of hot and
cold, wet and dry, snowpack and snowmelt, wind and storm tracks, and ocean
currents and upwellings; and not just the magnitude and geographic distribution of all of these, but also the timing.
As unusual as the
current cold is for the U.S., the
global picture shows that January is not on course to break that 28 - year
warm streak, either.
