A
The increase in global temperatures due to climate change
B
The increase in atmospheric carbon dioxide levels
C
The rise in ocean levels and melting polar ice caps
D

Verified step by step guidance1
Understand the concept of mass extinction: Mass extinction refers to a significant and widespread loss of species in a relatively short period of geological time.
Identify the key indicator of a mass extinction: A rapid decline in biodiversity and species extinction rates is a primary indicator of a mass extinction event.
Consider the impact of human activities: Human activities such as habitat destruction, pollution, and overexploitation contribute to the rapid decline in biodiversity.
Evaluate the evidence: While climate change, increased carbon dioxide levels, and rising ocean levels are environmental concerns, the most direct evidence of a mass extinction is the accelerated rate of species extinction.
Conclude with the correct evidence: The rapid decline in biodiversity and species extinction rates is the most compelling evidence suggesting a potential sixth mass extinction.
