“Eleven of the highest average global annual temperatures
recorded since 1861 have come in the past 12 years.”
By Dr. Courtney:
“Yes, for about 300 years the globe has been warming
as it has recovered from the Little Ice Age (LIA). Of
course the warmest years are near the end of a warming
trend.
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.
Of importance is whether the warming from the LIA has
ended, will continue, or will reverse. As stated above,
mean global temperature has not again reached the high
it did in 1998 (an El Nino year) and it has been stable
for the last 6 years despite atmospheric carbon dioxide
concentration having increased by 4% since 1998.”
