2014 saw more Arctic wildfires than any year since the Ice Age.

Seems like it is talking about "recent decades" prior to 2013 and comparing to periods 500 and more years long.
If you are going to post a link, please try to characterise it reasonably.
During the Medieval Climate Anomaly (MCA; ∼1,000–500 cal B.P.), the period most similar to recent decades, warm and dry climatic conditions resulted in peak biomass burning, but severe fires favored less-flammable deciduous vegetation, such that fire frequency remained relatively stationary. These results suggest that boreal forests can sustain high-severity fire regimes for centuries under warm and dry conditions, with vegetation feedbacks modulating climate–fire linkages. The apparent limit to MCA burning has been surpassed by the regional fire regime of recent decades, which is characterized by exceptionally high fire frequency and biomass burning. This extreme combination suggests a transition to a unique regime of unprecedented fire activity. However, vegetation dynamics similar to feedbacks that occurred during the MCA may stabilize the fire regime, despite additional warming.
seems to be saying we are getting more biomass burning but may well get stabilization of high fire frequency as vegetation responds.
Every occurrence of 'decade' seems to be part of recent decade
s or several decade
s or similar. The shortest period referred to seems to be
The subsequent sharp rise in CHAR to values similar to the MCA peak corresponds to marked warming and increased forest burning in Alaska during the past few decades (32).
Even 'past few decades' seems rather longer than one year.
