Answer to Question 1

See Figure 18-17b. While overall global temperature has increased a moderate 1.1F, temperatures in Alaska, Siberia, and northwestern Canada have risen 5F in summer and 10F in winter. Spring comes two weeks earlier in the Arctic than it did at the turn of the 21st century.

Answer to Question 2

Flowing air leads to vertical and convection currents and jet streams that lead to the weather that we experience day to day. Climate is the result of weather patterns that occur over long periods of time (more than 10 years at a time).
