" Snow cover over North America and much of Siberia, Mongolia and China is greater than at any time since 1966. "
Contrary to popular belief in climatic stability during recent times, the Earth's
climate of the past 1000 years has changed significantly.
The Medieval climatic optimum (AD 700-1200) was a time of extremely
favorable climate in northern Europe. Harvests were good, fishing was abundant,
sea ice remained far to the north, vineyards flourished 300 miles north of their
present limits, and famine was rare. This was the period of great Viking expansion
from Scandinavia. Viking settlements were based on cereal grains (wheat and
barley) and dairy herds (goats, sheep, and cattle).
Iceland began settling in AD 874 and soon became an independent republic.
Greenland was colonized in AD 985 by Erik the Red. By the 12th century,
two sizeable communities existed in southwestern Greenland.
During the Medieval climatic optimum, sea level stood at least a half meter
higher in southern Florida than today from the first through tenth centuries.
In other words, sea levels in the Atlantic have fallen at least
19 inches in the last 1,000 years.
Climatic deterioration began in the 1200s; glaciers expanded in Iceland and in
the Alps. Vineyards began declining in Germany and by the 1300s had completely
disappeared in England. Fishing replaced cereal grains as the main source of food
in Iceland, and sea ice expanded southward between Greenland and Iceland.
Around 1340-50 the more northerly of the two Greenland communities was
abandoned to the Inuits. By 1510, only Inuits remained. Cold climate reduced
dairy production, and extensive sea ice hampered essential trade with Europe.
Across the Pacific Islands, during the period AD 1270-1475, sea level fell
by more than a meter and temperatures declined an average 1½EC. El Niño
increased in frequency, and precipitation increased.
Sea levels fell by more than three feet in a thousand years!
And we’re worried about a rise of .03 millimeters (supposedly)
per year?
Please note that "El Niño increased in frequency, and
precipitation increased."
That’s exactly what is happening today!
That’s how ice ages begin!

Earth’s climate during the last 1,000 years
Medieval climatic optimum (AD 700-1200).
Medieval glaciation (AD 1200-1460).
Brief climatic improvement (AD 1460-1560).
Little Ice Age (AD 1560-1890).
Modern climatic optimum (AD 1890-2000).

Hmmmm. Sea levels are falling in the Pacific Ocean,
sea levels are falling in the Indian Ocean, sea levels are
falling in the Atlantic Ocean, and sea levels are falling
in the Arctic Ocean.
I somehow get the feeling that we’re not getting the full
story here.

" Snow cover over North America and much of Siberia, Mongolia and China is greater than at any time since 1966. "
Sea levels falling in the Atlantic Ocean"I believe that 2005 is the warmest year, because the main source of difference is the Arctic, and I believe it is likely that our estimate there is in the right ballpark even though it is based on some extrapolations," Hansen said. "However, I admit that it could be wrong, in which case 2005 might be slightly cooler than 1998."
