“Over thousands of years, changes in atmospheric
conditions, such as gas concentrations, and singular
events - volcanic eruptions, for instance - have caused
climate change. Most of those changes have taken hundreds
or thousands of years to play out. But climatologists
now agree that the world appears to be in a sustained,
relatively rapid period of warming.”
By Dr. Courtney:
“It is nonsense to assert that, “Most of those changes
[i.e. from vulcanism and atmospheric gas changes] have
taken hundreds or thousands of years to play out”. The
climate recovers from a volcanic event in less than 5
years. And stomata measurements indicate that atmospheric
carbon dioxide concentrations have varied over decades
throughout recent millennia.
Importantly, it does not matter what some climatologists
may or may not think because the real world’s behaviour
shows nothing unusual. As stated above, two thousand years
ago – in Roman times – the Earth was warmer than now.
After that it was cooler than now throughout the Dark
Ages. That cool period was followed by the so-called Medieval
Warm Period when the Vikings farmed Greenland and an insect
now constrained to the South of France inhabited York.
Then the Earth cooled to the so-called Little Ice Age.
The Earth has been warming out of the Little Ice Age for
the 300 years since then. Around 1700, Londoners used
to have “Ice Fairs” on the frozen Thames each year. The
last Ice Fair was held in 1814, and the Thames has not
frozen solid since.
There is no reason to suppose that recent warming is
not a completely natural recovery from the Little Ice
Age that is similar to the recovery from the Dark Age
cool period to the Medieval Warm Period. And the globe
was warmer than now at the height of the Medieval Warm
Period.”
