Climate change refers to significant, long-term changes in the global climate, primarily caused by human activities such as burning fossil fuels, deforestation, and industrial processes. These actions increase greenhouse gases like carbon dioxide in the atmosphere, leading to global warming and altering weather patterns. Current global challenges include rising temperatures, melting polar ice, and more frequent and severe weather events like hurricanes, droughts, and wildfires. These changes threaten biodiversity, disrupt ecosystems, and impact human health and livelihoods. Coastal regions face increased flooding and erosion, while agricultural productivity is affected by altered rainfall patterns. Addressing climate change requires urgent global cooperation to reduce greenhouse gas emissions, transition to renewable energy sources, and implement sustainable practices. Additionally, adaptation strategies are crucial to protect vulnerable communities and ecosystems from the ongoing impacts of climate change.
