For the model in fig. 8.3, the value at = 0.9 yields a temperature t=295 k assuming latex: e_s=235\: \mathrm{w}\: \mathrm{m^{-2}}

(a) calculate the value of at that would increase t by 4latex: ^\circ∘c .

(b) assuming this change in at is driven by increases in atmospheric co2, describe the changes we would see in fig. 7.1b (referring to case ii) and fig. 7.2 referring to wavelengths around 15 latex: \mu m

What is the result of the greenhouse effect? a. heat is deflected from the atmosphere. b. heat is released from the atmosphere. c. heat is kept in the atmosphere. d. plants are able to grow in the tropics where the air is the heaviest.

This map shows the member states of the european union (eu). based on this map, what is the most likely reason the eu was formed? a) to increase trade between european nations b) to protect themselves from foreign enemies c) to begin the process of forming one large nation d) to isolate europe from the rest of the international community j

The great scientist alfred wegener proposed that continents have moved, while other scientists such as t.c.chamberlin argued against wegener. wegener's ideas eventually won, and are now widely accepted, because: a) wegener's ideas were more beautiful, and so were favored by the intellectual elite.b) wegener's ideas did a better job of predicting the results of new observations and experiments.c) wegener's ideas appealed to dead white european males, whereas chamberlin's didn't.d) wegener's ideas appalled dead white european males, and we all know that in this politically correct era,dead white european males cannot get a fair shake.e) wegener won the nobel prize.
