Which of the following statements about climate change is correct?

The statement that climate change is influenced by human activity is correct because extensive scientific research has established a clear link between human actions—such as burning fossil fuels, deforestation, and industrial processes—and the increase in greenhouse gases in the atmosphere. This accumulation of greenhouse gases leads to the greenhouse effect, which raises global temperatures and causes various climatic changes. The overwhelming consensus among climate scientists is that human activities are a significant driver of contemporary climate change, particularly through the substantial rise in carbon dioxide and other greenhouse gas concentrations since the Industrial Revolution.

In contrast, climate change does not solely affect land temperatures; it has widespread effects on ocean temperatures, ice melt, and global weather patterns. Furthermore, climate change tends to make weather more volatile rather than predictable, resulting in more frequent and severe weather events. Lastly, climate change indeed impacts biodiversity, as shifts in climate can alter habitats, food sources, and migration patterns for many species, leading to threats to their survival.
