Drivers that accentuate the greenhouse effect Which of the following human activities intensify the greenhouse effect and thereby contribute to global warming?

Introduction / Context:
The greenhouse effect is a natural phenomenon, but human activities have strengthened it by increasing atmospheric greenhouse gases. Recognizing the broad categories of contributing actions is fundamental to environmental engineering and policy.

Given Data / Assumptions:

• We evaluate three activity classes: land-use change, industrialization, and transportation.
• We seek the combination that intensifies greenhouse forcing.

Concept / Approach:
Deforestation reduces carbon sinks and often emits CO₂ via biomass burning and decay. Rapid industrialization generally increases fossil fuel consumption, emitting CO₂ and other greenhouse gases. Transportation growth raises fuel combustion emissions (CO₂, N₂O), and methane can rise from associated supply chains. Together, they elevate atmospheric greenhouse gas concentrations and radiative forcing.

Step-by-Step Solution:

Verification / Alternative check:
Emission inventories attribute large shares of global CO₂ to power/industry and transport; land use change is also a major contributor historically and regionally.

Why Other Options Are Wrong:

Common Pitfalls:
Confusing ozone layer issues with greenhouse forcing; while both are atmospheric topics, their mechanisms and key gases differ.

Final Answer:
all (a), (b) and (c).
