what do scientific models predict will happen to earths oceans if current trends continue unmitigated?

a. the acidity of ocean water will remain near a neutral ph.
b. polar ice will continue to melt and refreeze in a natural cycle.
c. sea level will rise between 2.5 and 6.5 feet.
d. coral bleaching will stop, and coral reefs will slowly recover.

Explanation:

• Option A: Ocean acidification is occurring due to increased carbon dioxide absorption, so ocean water acidity will not remain neutral.
• Option B: Polar ice is melting at an accelerated rate due to global warming, not just in a natural cycle.
• Option C: Scientific models predict sea - level rise if current trends (like global warming causing ice melt) continue.
• Option D: Coral bleaching is likely to continue or worsen with ongoing stressors like warming waters and ocean acidification.

Answer:

C. Sea level will rise between 2.5 and 6.5 feet.
