Topic: Little Ice Age

Geologist Ian Plimer's arguments against catastrophic global warming are presented, focusing on the historical context of temperature measurements. Plimer argues that the planet has been cooling for 4,000 years and that recent warming is merely a recovery from the "Little Ice Age" that ended in 1850.

A geologist argues that climate has always changed, citing the Medieval Warm Period (1000 AD) as a time of prosperity that was later "erased" by Michael Mann's hockey stick graph. The speaker claims he was denied an NPR interview because he refused to attribute warming to human activity. He asserts that the current "irrational hysteria" in the media ignores 100 previous studies confirming that historical warming was global and natural.

Severe winter weather across Europe and the UK prompted warnings from the NHS regarding a "perfect storm" of freezing temperatures, norovirus, and flu. Reports of snow in Rome and Ireland are cited as evidence for a potential "little ice age" or global cooling trend.

Researchers reporting in Nature Geoscience acknowledge an unexplained standstill in global warming since 1998. The late climatologist Reid Bryson is cited for his view that current warming is a natural recovery from the Little Ice Age rather than a result of human activity.
