Question

what potential greenhouse gas emission scenario could cause a 4°c temperature increase? current emission trends significant global emission reductions increased renewable energy use complete cessation of industrial activity

Explanation:

Increased greenhouse - gas emissions lead to global warming and temperature increases. Current emission trends, if not reversed, could result in significant temperature rises. Complete cessation of industrial activity would reduce emissions greatly and likely slow or reverse warming. Increased renewable energy use would lower fossil - fuel based emissions and reduce warming. Significant global emission reductions are needed to limit temperature increases. A continuation of current emission trends is most likely to cause a 4°C temperature increase as it implies no significant action to reduce emissions.

Answer:

Current emission trends
