The following table provides an overview and summary of materials
within the Climate Timeline website.

Climate
Science
Weather
and climate forecasting have improved dramatically in recent years,
yet accurate long-term forecasts remain elusive due to the complexity
of climate systems.
|
Climate
History
Human development and history has occurred since the end of the
last Ice Age, and primarily in the relatively warm Holocene period
of the past 10,000 years or so. Here we explore the relationship
between humans and climate.
|
Resources
Online Resources and Inquiry Ideas for further explorations
in climate processes and the link to human culture.
|
|
Daily
Diurnal Cycle
Weather variability occurs at a scale of minutes, hours, and days,
with the Earth's rotation on it's axis being a primary force for
change.
|
Today
Exploring how environmental systems and human activities are impacted
by daily cycles.
|
Today
Links to resources about today's weather and more.
|
|
Annual
Cycle
The annual orbit of the Earth around the sun and the resulting
seasonal changes in the atmosphere and oceans that dominate annual
climate dynamics.
|
1
Year
Examining how flora and fauna adapt to seasonal
variability through migration and adaptation.
|
1
Year
Inquiry
into annual fluctuations and links to resources.
|
|
Interannual
Scale
The oceans, with their great heat capacity and slow changing properties,
give rise to climate processes like El Niño and La Niña.
|
Past
10 Years
El
Niño Southern Oscillation's
twin pulses of El Niño warming and La Niña cooling
have impacted socio-ecological conditions in many parts of the
world.
|
10
Years
Resources
on ENSO include animations, plus inquiry ideas.
|
|
Decadal
Scale
Internal
ocean variability can be tracked through paleoclimatic data. Processes
like the Pacific Decadal Oscillation and North Atlantic Oscillation
occur on this scale.
|
Past
100 Years
Human
population and carbon dioxide in the atmosphere grew exponentially
during the 20th Century while climate-related events impacted
billions of people.
|
100
Years
The
single most important factor in climate change during the 20th
century may well prove to be human population growth.
|
|
Centennial
Scale
Internal
variability, including ocean and land carbon cycles and external
forces such as solar variability and greenhouse gases that influence
variability at the millennial scale.
|
Past
1,000 Years
Paleoclimatic
records show large volcanic events and multi-decadal droughts
in many parts of the world over the past millennium, contributing
to social stress for people such as the Anasazi in the American
southwest.
|
1,000
Years
What
does the paleo record show about climate during the past 1000
years? Examining the "Little Ice Age" in Europe.
|
|
Millennial
Scale
Data spanning multiple millennia allows scientists to evaluate
the range of natural variability, the occurrence of abrupt climate
change, and assess human influences on climate variations.
|
Past
10,000 Years
Melting
glaciers and ice caps, rising sea levels and the flooding of the
Black Sea are all events of the Holocene period following the
last Ice Age.
|
10,000
Years
Learn
more about climate change, including abrupt events during the
Holocene.
|
|
Glacial
and Interglacial Scale
Milankovitch cycles, that include precession of the equinoxes
(23ky), obliquity (41ky) and eccentricity (100ky and 400ky periods),
influence climate change at larger time scales.
|
Past
100,000 Years
Ice
cores, ocean sediments and other records provide the oldest
evidence of climatic variability over the span of thousands
of years.
