Human-caused climate change is affecting the boreal forests/taiga and tundra biomes due to rising temperatures, changes in precipitation, and other phenomena such as wildfires. For example, in 2016, a devastating wildfire destroyed about 6,000 square kilometers of forest around Fort McMurray and nearly overwhelmed the city itself. Over time, these effects will bring about changes in the geographic distribution of these biomes and the types of land cover in this region. Based on the temperature change that is predicted to occur according to the worst-case projections of global surface warming, which of the following answer choices best describes how land cover will most likely change along your line from Fort McMurray, Alberta to Repulse Bay, Nunavut by the end of the twenty-first century?

a. Warmer temperatures will result in the evergreen forest changing to a mixed forest.
b. Warmer temperatures will cause the amount of grassland to increase.
c. Warmer temperatures will cause the region Of evergreen forest to shift northward.
d. Warmer temperatures Will result in the grasslands being converted to cropland and natural vegetation.
