Scientists differentiate between the 'current' carbon cycle and 'stored' carbon. Based on the diagram, why does burning coal have a much larger impact on the Earth's atmospheric balance compared to burning modern wood?
A.Coal releases carbon that was safely trapped underground for millions of years, adding 'extra' to the current atmosphere.
B.Modern wood contains no carbon, so it does not release any when it is burned.
C.Coal is an inexhaustible resource, meaning its carbon is automatically recycled by the Earth every day.
D.Wood takes millions of years to grow, while coal can be replaced by nature in just a few decades.
