Human activities and Natural processes are the cause of Climate change.                           Human activities include 1. Industrial Processes: Emissions from manufacturing and chemical production releases greenhouse gases contributing to the greenhouse effect. 2. Waste management: causes landfills and waste treatment impact as organic waste decomposes anaerobically. 3. Deforestation: clearing forests for agriculture, logging, and urban development reduces the number of trees that can absorb carbon dioxide.                                                                                     Natural Processes: 1. Solar variability changes in solar radiation affect the earth’s climate. 2. Ocean currents change in ocean circulation patterns impact climate variability.  3. Volcanic activity contributes to greenhouse gas emissions over longer periods.                                                                                                                                  Impact on the global Ecosystems; Temperature increase, Sea level rise, ocean acidification, loss of biodiversity, etc..
