Cold? What cold? Most of the globe had a mild winter
The central and eastern USA shivered through a colder-than-average winter, but most of the rest of the globe did not share in the chill, registering the eighth warmest overall winter on record.
Globally, Dec-Feb was actually very close to the median since the 1970’s ice age scare.
Excluding the volcano cooled years, the past Dec-Feb was just above the mean since 1979. There is no global warming story here, but the usual government fraudsters spun it into one.
