Climate Change - Page 27

Climate change refers to significant and lasting alterations in the Earth's climate and weather patterns over extended periods, typically decades to millions of years. It primarily concerns the increase in average global temperatures due to human activities, particularly the emissions of greenhouse gases such as carbon dioxide and methane. These gases trap heat in the atmosphere, leading to a greenhouse effect that causes warming. Climate change encompasses various impacts, including rising sea levels, increased frequency and intensity of extreme weather events, shifts in wildlife populations and habitats, and changes in agricultural productivity. It is a global issue that affects ecosystems, human health, economy, and society, necessitating coordinated international efforts for mitigation and adaptation strategies.
