Final answer:
The leaders may face internal pressures and international ambitions, poorer countries argue for economic development, and some political leaders question the need to address climate change.
Step-by-step explanation:
The leaders of the conference where Jack presents his data may not want to make any dramatic changes to reduce emissions for several reasons:
- The leaders may face internal pressures and international ambitions that make it difficult for them to take action on reducing emissions.
- Poorer countries argue that they have the right to continue economic development linked to emissions, while richer countries may be hesitant to break the status quo that favors continued greenhouse gas emissions.
- Some political leaders may question the need to address climate change due to the influence of organizations and companies with a vested interest in maintaining the status quo.
