"Surface temperatures in the Sargasso Sea, a 2 million square mile
region of the Atlantic Ocean, with time resolution of 50 to 100 years and
ending in 1975, as determined by isotope ratios of marine organism remains
in sediment at the bottom of the sea. The horizontal line is the average
temperature for this 3,000-year period. The Little Ice Age and Medieval Climate
Optimum were naturally occurring, extended intervals of climate departures
from the mean. A value of 0.25 °C, which is the change in Sargasso
Sea temperature between 1975 and 2006, has been added to the 1975 data in
order to provide a 2006 temperature value." -Arthur Robinson, Noah Robinson, and Willie Soon

"The average temperature of the Earth has varied within a range of
about 3°C during the past 3,000 years. It is currently increasing as the
Earth recovers from a period that is known as the Little Ice Age, as
shown above. George Washington and his army were at Valley
Forge during the coldest era in 1,500 years, but even then the temperature
was only about 1° Centigrade below the 3,000-year average."



"Atmospheric temperature is regulated by the sun, which fluctuates
in activity as shown above; by the greenhouse effect, largely
caused by atmospheric water vapor (H2O); and by other phenomena
that are more poorly understood."
