Modern Spike Outmatches Naturally Driven ‘Medieval Warm
Period'
Summers on the Norwegian archipelago of Svalbard are now
warmer than at any other time in the last 1,800 years, including during
medieval times when parts of the northern hemisphere were as hot as, or hotter,
than today, according to a new study in the journal Geology.
“The Medieval Warm Period was not as uniformly warm as we
once thought--we can start calling it the Medieval Period again,” said the
study’s lead author, William D’Andrea, a climate scientist at Columbia
University’s Lamont-Doherty Earth Observatory. “Our record indicates that
recent summer temperatures on Svalbard are greater than even the warmest
periods at that time.”
