Question at position 26 An examination of natural climate change factors reveals that the recently observed climate changes, such as the rate of warming in recent decades, are greater than can be explained by any natural factors. TrueFalse

Question

BlackTom AI · Accepted Answer

The question asks about whether observed climate changes, including the recent rate of warming, can be explained only by natural factors. 
Option 1: True. This choice asserts that natural climate drivers alone cannot account for the observed rapid warming in recent decades. In scientific assessments, natural factors such as solar variability and volcanic activity are considered, but they do not sufficiently explain the magnitude and pattern of recent warming. The large body of evidence points to human activities, especially greenhouse gas emissions and land-use changes, as the dominant influence on the recent trend. This reasoning aligns with consensus findings from major scientific bodies, which show that the warming observed over the last several decades is unlikely to be explained by natural factors alone. 
Option 2: False. This statement would claim that natural factors are enough to explain the observed changes. The contrary view is inconsistent with the extensive attribution studies that separate natural variability from anthropogenic forcing. While natural factors can contribute to fluctuations, the sustained rate and global pattern of warming, including ocean heat uptake and fingerprinting analyses, indicate a substantial human influence; therefore attributing all recent changes to natural factors would be inaccurate. 
In summary, option 1 correctly reflects the understanding that natural factors cannot fully explain the observed climatic changes, whereas option 2 incorrectly minimizes the role of human-caused forcings and overemphasizes natural variability.
