True/False
The Earth radiates as much energy back into space as it receives from the Sun.
Analysis
As water temperatures increase, the solubility of gases in the water decreases, so the oceans release carbon dioxide.
As surface temperatures increase, the rate of plant growth increases, removing carbon dioxide from the atmosphere.
As surface temperatures increase, the amount of the surface covered with snow and ice decreases.
As surface temperatures increase, decay rates for vegetation increases. Decaying plants produce methane.
As surface temperature increases, so does evaporation; increasing the clouds which reflect sunlight
Refer to the figure. The graph shows variations in temperature over the last 400 thousand years. Based on the natural cycles found in the graph, what would you predict the climate will do in the future? 
What do we call a gas which transmits higher energy visible photons but absorbs a large fraction of infrared photons?
Which of the following can be used to estimate temperatures in ancient climates?
Which of the following affects the amount of solar energy absorbed by the Earth?
