Climate change refers to long-term shifts in temperatures and weather patterns, primarily caused by human activities such as burning fossil fuels, deforestation, and industrial emissions. These activities increase the concentration of greenhouse gases like carbon dioxide in the atmosphere, trapping heat and causing the Earth's average temperature to rise. This phenomenon, known as global warming, disrupts natural climate systems and contributes to more frequent and severe weather events, such as hurricanes, droughts, floods, and wildfires.
The global impact of climate change is far-reaching. Melting polar ice and rising sea levels threaten coastal communities and ecosystems. Agricultural systems are under pressure due to changing rainfall patterns and extreme weather, affecting food security worldwide. Additionally, biodiversity is at risk as species struggle to adapt to rapidly changing habitats. Climate change also has social and economic consequences, particularly for vulnerable populations in developing countries. Addressing this crisis requires international cooperation, sustainable practices, and a shift toward renewable energy sources to reduce global greenhouse gas emissions. Shutdown123
