Does the observed acceleration of globally averaged abyssal ocean warming support the idea that it's a natural, rather than anthropogenic event?

A new study suggests a faster rate of warming in deep oceans since 2000 compared to previous decades.

• Option 1: Yes, this supports a natural cause
• Option 2: No, it likely results from human activities
• Option 3: The data is still too early to determine the exact nature of the warming
• Option 4: Uncertain
