Carbon sinks have generally matched the addition of carbon dioxide to the atmosphere until ________.
A) the end of the last ice age,approximately 16,000 years ago
B) the Little Ice Age,approximately 400 years ago
C) the onset of intensive industry and fossil fuel burning by humans,around the year 1850
D) the Eocene Epoch,approximately 50 million years ago

Question

Quizplus · Accepted Answer

The onset of intensive industry and fossil fuel burning by humans, around the year 1850, marked the accelerated addition of carbon dioxide to the atmosphere. This addition has exceeded the capacity of carbon sinks to absorb and store carbon, leading to an increase in atmospheric carbon dioxide levels and contributing to climate change. The other options mentioned in the question do not correspond with the historical timing of human industrial activities and increased carbon emissions.
