Change of any kind should be described in terms of the time over which the change takes place. Describe global climate change on these time scales:
 
  (a) during the last 180 million years, (b) during the Cenozoic, (c) during the Quaternary, (d) during the last 21,000 years, (e) during the last 1000 years, (f) during the last century, (g) during the last decade.
  What will be an ideal response?

Question 2

Why is it that London, England, is relatively warm even though it is located at the same high, cold latitude as Hudson Bay, Canada?
 
  What will be an ideal response?

Answer to Question 1

a) Overall temperature has cooled over the last 180 million years, with many fluctuations.
b) Overall temperature has cooled during the Cenozoic, especially since about 40 million years ago.
c) Temperatures have fluctuated strongly during the Quaternary between very cold (ice age) and very warm times.
d) During the last 21,000 years, the overall temperature has warmed, because the peak of the last ice age was at 21,000 years ago.
e) There have been some ups and downs in temperature over the last 1000 years but the overall trend has been toward warmer conditions.
f) The overall trend over the last century has been warming, with some short-lived cooling spells (e.g., 19301940).
g) Temperatures have increased over the last decade.

Answer to Question 2

London, England, is close to the North Atlantic Ocean where a conveyor-belt circulation pattern brings warm water northward from the equator. This warm water radiates heat into the atmosphere, maintaining warmer air temperatures than would otherwise be expected at this latitude.

YES! Correct, THANKS for helping me on my review
