Why is the Climate System Important?
• The climate system determines the weather.
The weather affects many of our daily
decisions.
• Climate affects long-term decisions by
humans.
• Climate affects long-term trends in plants and
animals.
What do you think?
• The following video talks about weather,
climate, and climate change.
• While watching the video, think about
whether the terms weather and climate are
used appropriately given the definitions.

Seven of these indicators would be expected to increase in a warming
world and observations show that they are increasing. Three would be
expected to decrease and they are decreasing.

New Vocabulary
• Köppen classification
system
• Tropical climates are
characterized by constant high
temperature (at sea level and
low elevations) — all twelve
months of the year have
average temperatures
of 18°C (64 °F) or higher.
New Vocabulary
• Köppen classification
system
• Dry (arid and
semiarid)
climates[edit]
• These climates are
characterized by the fact that
actual precipitation is less
than a threshold value.
New Vocabulary
• Mild Temperate/mesothermal climates
• These climates have an average temperature
above 10 °C (50 °F) in their warmest months
(April to September in northern hemisphere), and a
coldest month average between −3 and 18 °C
(27 and 64 °F).
• Dry-summer subtropical or Mediterranean climates San
