Based on the provided map and table data, which statement best summarizes the projected impact of climate change on suitable days for plant growth across different nations, particularly considering their economic type and income category?

  • A: Industrial economies, regardless of income level, are projected to experience the most severe decline in suitable days for plant growth.
  • B: Nations with agricultural economies and lower per capita incomes are generally projected to face significant reductions in suitable days for plant growth.
  • C: The projected changes in suitable days for plant growth show no clear correlation with a nation's economic type or per capita income category.
  • D: High-income nations, whether industrial or agricultural, are uniformly projected to experience an increase in suitable days for plant growth.

Explanation

The map clearly shows large areas of tropical and lower-latitude regions where many agricultural and lower-income nations are located, like India, Nigeria, Ethiopia, Vietnam, Egypt experiencing significant negative changes red/orange colors , indicating a substantial decrease in suitable days for plant growth. Conversely, some higher-latitude, industrial, and high-income nations like the US and parts of Russia/Japan show blue colors, indicating an increase or smaller decrease, suggesting a disparity in impact. This aligns with the statement that agricultural economies and lower-income nations are generally more negatively affected.
