A. 2. we have the record of sunspots back to 1600s no sunspots for 80 years during the 17th century (maunder minimum) - weaker sun: more volcanoes. Laki eruption in iceland in 1783 cause unusual cold. 1816 year without a summer- mount tamboura indonesia - largest eruption in recorded history. Driver of northern hemisphere for last 1000 years. B. 3. a) big dips in solar energy occur after volcanic eruptions: little ice age does not mean we are not causing the warming or that climate is not sensi- tive to forcing. Considerable regional variability until the last 50 years. C. 1. a) now its getting warmer everywhere: global temperature has not done much for the last 10,000 years.
