1. WHAT IF? Changes in Earth’s climate at the end of the last ice age happened gradually, taking centuries to thousands of years. If the current global warming happens very quickly, as predicted, how may this rapid climate change affect the evolution of long-lived trees compared with that of annual plants, which have much shorter generation times?   2. Focusing just on the effects of temperature, would you expect the global distribution of C4 plants to expand or contract as Earth becomes warmer? Why? Plants with C4 photosynthesis are likely to expand their range globally as Earth's climate warms. C4 photosynthesis minimizes photorespiration and enhances sugar production, an advantage that is especially useful in warmer regions where C4 plants are found today.

1. WHAT IF? Changes in Earth’s climate at the end of
the last ice age happened gradually, taking centuries
to thousands of years. If the current global warming
happens very quickly, as predicted, how may this rapid
climate change affect the evolution of long-lived trees
compared with that of annual plants, which have much
shorter generation times?
