Which impact is associated with high levels of greenhouse gas emissions?

High levels of greenhouse gas emissions are predominantly associated with climate impact. Greenhouse gases, such as carbon dioxide, methane, and nitrous oxide, trap heat in the atmosphere, leading to an increase in global temperatures and resulting in various climate-related changes. This phenomenon brings about severe weather patterns, melting glaciers, rising sea levels, and shifts in ecosystems and wildlife habitats.

Understanding climate impact is crucial as it affects not only the environment but also socio-economic factors like agriculture, health, infrastructure, and water resources. Other impacts such as water eutrophication, aquatic toxicity, and soil acidification, although important environmental concerns, are not directly driven by greenhouse gas emissions but rather stem from other factors, such as nutrient runoff, pollutants, and chemical imbalances in soils and water bodies. Therefore, the correct association of high levels of greenhouse gas emissions is with climate impact.
