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

Carbon dioxide (CO2) is the most significant greenhouse gas contributing to climate change due to its high concentration in the atmosphere and its ability to trap heat.

Climate change refers to the long-term changes in temperature and weather patterns, while global warming is a specific aspect of climate change related to the increase in Earth's average temperature.

Improved agricultural yields are not a potential consequence of climate change, as climate change is generally expected to have negative impacts on agriculture due to changes in temperature, precipitation patterns, and the spread of pests and diseases.

Climate adaptation refers to the process of adjusting to the impacts of climate change, such as by developing new agricultural practices, building sea walls to protect coastal communities, or implementing early warning systems for extreme weather events.

The Paris Agreement is an international agreement that aims to limit global warming to well below 2 degrees Celsius, preferably to 1.5 degrees Celsius, compared to pre-industrial levels.

Climate mitigation refers to the process of reducing greenhouse gas emissions to mitigate climate change, such as by transitioning to renewable energy sources, improving energy efficiency, and reducing deforestation.

Natural gas is a fossil fuel and is not considered a renewable energy source.

Climate resilience refers to the ability of a system or community to withstand and recover from the impacts of climate change.

Increasing the use of fossil fuels is not a potential adaptation strategy to address the impacts of climate change, as it would contribute to greenhouse gas emissions and exacerbate climate change.

Climate engineering refers to the intentional manipulation of the Earth's climate system to mitigate climate change, such as by injecting aerosols into the stratosphere to reflect sunlight or using carbon capture and storage technologies.

Increased energy efficiency is not a potential risk associated with climate engineering.

Climate resilience refers to the process of reducing the vulnerability of a system or community to the impacts of climate change.

Increased greenhouse gas emissions are not a potential benefit of climate adaptation.

Climate mainstreaming refers to the process of integrating climate change considerations into decision-making and planning processes.
