- Scientists see a new problem in the ocean today.
- Tiny microplastics are now found in many ocean places.
- Small plastic pieces mix with organic material in samples.
- When burned, plastics give carbon that looks like natural.
- Lab tests can count plastic carbon as natural carbon.
- This problem can change carbon measurements in ocean water.
- Climate models may be affected by wrong carbon data.
- Scientists say labs should use better sample methods now.
