used to define a region's:
A major source of climate Intergovernmental Panel on Climate Change

IPCC whose full name is:
When moist air hits a rain shadow effect
mountain it rises, cools,
and drops its moisture as
rain on one side of the
mountain. As the air moves
over the mountain, the
area it passes over will get
less rain over time than the
other side of the
mountain. This
phenomenon is called the:
The isotopes of oxygen neutrons

_____________ in their nucleus.
,Reliable records of air True
temperature
measurements go back
about 200 years. To
estimate temperatures
older than 200 years we
have to use proxies that
allow us to estimate
temperature from them.
Examples of proxies
include stomata in fossil
leaves and tree rings.
Oxygen isotopes are used More 16O in water is locked up in ice on land.
to estimate temperatures
of the past. The ratio of
18O to 16O (18O/16O) is
measured as a proxy for
temperature. During
colder periods the ratio of
18O/16O in ocean water is
larger than in warmer
periods because:
Approximately 200 to 300 volcanic eruptions that spilled lava over a massive
million years ago the area over a 1 million-year period.
Earth's average
temperature was thought
to be over 10 oC warmer
than today's. Mass
extinctions occurred. One
theory for the warmer
temperature is that the
atmosphere held high
concentrations of CO2
gas. The source for this
gas was:
, When the Earth's rock weathering reactions which took the CO2 out of

These large quantities of

Anomalies are calculated

whole region, but the
changes over time at that
station are likely to track
the changes throughout
