Carbon Dioxide (CO2) is the primary greenhouse gas emitted by human activities, primarily through the burning of fossil fuels for energy production and transportation.

Flying on an airplane is generally the most carbon-intensive activity an individual can engage in, due to the high emissions produced by jet engines and the altitude at which planes fly.

Global Warming refers to the long-term increase in global average temperatures, primarily caused by the accumulation of greenhouse gases in the atmosphere.

Oxygen (O2) is not a greenhouse gas because it does not absorb and trap heat in the atmosphere like other greenhouse gases.

Carbon Footprint refers to the amount of greenhouse gases produced to directly and indirectly support human activities, usually expressed in terms of carbon dioxide equivalents (CO2e).

Natural Gas is a fossil fuel and therefore not a renewable energy source.

Agriculture, particularly the expansion of large-scale farming and cattle ranching, is the primary cause of deforestation in tropical rainforests.

Increased agricultural productivity is not a consequence of climate change, but rather a potential impact of certain climate change mitigation strategies.

The primary objective of the Paris Agreement is to limit global temperature rise to 1.5 degrees Celsius above pre-industrial levels, with efforts to limit it to 2 degrees Celsius.

Increasing the use of fossil fuels would increase greenhouse gas emissions, not reduce them.

Carbon Sequestration refers to the process of capturing and storing carbon dioxide from the atmosphere, typically through natural or technological means.

Enhanced marine biodiversity is not a potential consequence of ocean acidification, but rather a potential impact of certain ocean acidification mitigation strategies.

Carbon Neutrality refers to the process of reducing greenhouse gas emissions to net zero, typically achieved through a combination of emissions reductions and carbon sequestration.

Geographic location is not a key factor in determining an individual's carbon footprint, as it is more influenced by personal choices and behaviors.

Climate Adaptation refers to the process of adjusting to the impacts of climate change, typically through measures that reduce vulnerability and increase resilience.
