Water vapor is a natural component of the Earth's atmosphere and is not considered a greenhouse gas in the context of climate change.

Human activities, particularly the burning of fossil fuels, are the primary cause of climate change.

The transportation sector is the largest contributor to global greenhouse gas emissions, accounting for approximately 23% of total emissions.

Climate change refers to the long-term shift in weather patterns and average temperatures over an extended period of time.

Improved crop yields are not a potential impact of climate change, but rather a potential benefit of certain adaptation strategies.

The primary goal of climate change mitigation is to reduce greenhouse gas emissions in order to limit the effects of climate change.

Geoengineering is not a research priority in the field of climate change, as it involves large-scale interventions in the Earth's systems that are not fully understood and may have unintended consequences.

Resilience refers to the ability of ecosystems to adapt to the impacts of climate change and maintain their structure and function.

Business leaders are not typically considered key stakeholders in climate change research and policy, although they can play a role in implementing mitigation and adaptation strategies.

Climate mainstreaming refers to the process of integrating climate change considerations into decision-making across all sectors and levels of government.

Increasing economic growth is not a potential benefit of climate change research, as the primary focus of climate change research is to mitigate and adapt to the negative impacts of climate change.

Energy efficiency refers to the process of reducing greenhouse gas emissions from existing sources by using energy more efficiently.

Increased food production is not a potential impact of climate change on human health, as climate change is generally expected to have negative impacts on agricultural yields.

Carbon capture and storage refers to the process of capturing carbon dioxide from the atmosphere and storing it underground or in other geological formations.

Public apathy is not a key challenge in climate change research, as there is generally a high level of public concern and awareness about climate change.
