Climate change is a long-term shift in weather patterns caused by both natural factors and human activities that increase greenhouse gases. It is occurring globally and is evidenced by rising sea levels, melting glaciers and sea ice, and more extreme weather events. Climate change affects all life on Earth by causing droughts, worsening storms, rising ocean temperatures that impact species migration and habitats, ocean acidification, and increased health issues for humans. While some deny the problem, the majority of scientists agree that climate change poses a severe risk and solutions like education, reducing pollution, and further research are needed to address it.
