Unprecedented recent summer warmth in Arctic Canada
Description: The extent to which recent Arctic warming has been anomalous with respect to long-term natural climate variability remains uncertain. In this journal article scientists used 145 radiocarbon dates on rooted tundra plants revealed by receding cold-based ice caps in the Eastern Canadian Arctic to show that 5000 years of regional summertime cooling has been reversed, with average summer temperatures of the last ~100 years now higher than during any century in more than 44,000 years.
