Read the scenario and answer the accompanying questions.

On some continents, these scientists are predicting forests spreading; however, when it comes to deserts and tropical biomes, they are finding predictions much more challenging, as it is uncertain how warmer temperatures will affect rainfall. -Understanding the basics of global climate change effects, the findings of this research on shifting biomes is most likely to predict________.
