Climate change can be caused by both human and natural factors and affects the environment in several ways. It is causing glaciers to melt and recede. Warmer temperatures allow pine beetles to destroy more forests as they can survive winters and move further north. Valuable Antarctic and Arctic habitats are threatened as temperatures rise. Rising sea levels from melting ice could flood coastal areas, causing deaths, land loss, and environmental damage. Individual actions like reducing carbon emissions, recycling, and conserving energy can help address climate change.
