B Correct answer
Explanation

Even with a 50% reduction in greenhouse gas emissions, global temperatures are still projected to rise by approximately 2°C by 2050 due to the cumulative effect of greenhouse gases already in the atmosphere. This is based on climate modeling studies. The warming wouldn't stop or reverse immediately due to climate inertia.
