topicclimatechange
Climate change refers to long-term shifts in global or regional climate patterns, including changes in temperature, precipitation, and the frequency or intensity of extreme weather events. It results from natural variability and, to a large extent, from human activities that alter the composition of the atmosphere, especially the rise in greenhouse gases such as carbon dioxide, methane, and nitrous oxide.
Causes include the burning of fossil fuels for electricity, heat, and transportation, which releases substantial amounts
Evidence for climate change is grounded in multiple lines of observation: rising global surface temperatures, warming
Impacts span environmental, economic, and social dimensions. Ecosystems shift and species migrate, while water resources, agriculture,
Responses focus on mitigation and adaptation. Mitigation aims to reduce or remove greenhouse gas emissions through
