On the heels of Europe’s remarkable summer of 2003, last autumn and winter were anomalously warm – as much as three standard deviations from normal, likely the warmest in 500 years, according to Luterbacher et. al in GRL.1 The coolest (pardon the pun) part:
Phenological impacts related to this warmth included some plant species having a partial second flowering or extended flowering till the beginning of winter. Species that typically flower in early spring were found to have a distinct earlier flowering after winter 2007.
