Around 1000, the Earth was warm enough that Greenland was colonized by
Vikings. This was followed by a "little Ice Age" that killed off the
Greenland colony. Earth has gone through many temperature swings -
mostly long before Humans could have had any impact on it.

The variability of the sun's output has more impact on the Earth's
temperature than man's puny efforts. The Chicken Little syndrome that
we are doomed unless (fill in your favorite solution) is not justified
if you look at the last 1000 years, let alone the last 500 million.

When the Earth was formed, and life began it's struggle, the sun put out
70% of the energy it does now. The increase in the sun's output over
billions of years has not prevented nearly freezing the Earth (the
Iceball Earth risk) nor warm periods long ago with higher temperatures
and CO2 than we now have. There have been many such cycles.

There is global warming to worry about. In another 4-8 billion years
the Sun will expand into a red giant. Fortunately, it will be gradual
for most of that time.

The computer models to predict catastrophe due to human impact have been
adjusted many times when the model didn't match the data. That should
give some sketicism about the model; when all the adjustments allow the
model to give the same output.

Has even one peer-reviewed study cast doubt on the whole "humans are
contributing to global warming" scenario? I know that a whole lot of
them support it, but I don't know if any contradict it.

I hear a lot of wailing and gnashing of teeth on both the Left and the
Right about this, but what do the actual honest-to-God living
breathing working *scientists* have to say about it?

Thanks for asking, Xenophile.

The National Climatic Data Center has long served the Nation as a national resource for climate information. NCDC develops national and global data sets used by government and the private sector. NCDC's climate data has been used in agriculture, air quality, construction, education, energy, engineering, forestry, health, insurance, landscape design, livestock management, manufacturing, recreation and tourism, retailing, transportation, and water resources management. The center's data fulfills needs ranging from building codes to power plant and space shuttle design.
