Explanation:
Answer:
Increased global temperatures, leading to a 20% reduction in rainfall
Explanation:
According to this question, forest fires are becoming rampant in tropical rainforests. Although this occurrence is natural, tropical rainforests do not typically undergo this natural process due to the average yearly amount of rainfall. This means that the high amount of rainfall in tropical rainforests help prevent or reduce the high cases of forest fire incidence.
However, the recent increased occurrence of tropical rainforest fires is most likely attributed to an INCREASE IN GLOBAL TEMPERATURES, LEADING TO A 20% REDUCTION IN RAINFALL. This is because an increase in the global atmospheric temperature causes the reduction of the amount of rainfall, which naturally helps curb the occurrence of forest fires.
