Climate change refers to long-term alterations in temperature, precipitation, wind patterns, and other aspects of the Earth's climate system. These changes are primarily driven by human activities, particularly the burning of fossil fuels, deforestation, and industrial processes, which increase concentrations of greenhouse gases in the atmosphere. Climate change is a significant concern because it leads to severe environmental impacts, such as rising sea levels, more frequent and intense weather events, loss of biodiversity, and disruptions to ecosystems. These effects pose serious risks to human health, food and water security, economic stability, and overall quality of life, making it imperative to address and mitigate the drivers of climate change.
