Explain various causes for the changes in climate and its effect on both the living and non-living bodies on the Earth.
In short
Climate change today is driven mainly by human greenhouse gas emissions from fossil fuels, deforestation and agriculture, alongside natural factors like solar cycles and volcanoes. It harms living bodies through biodiversity loss, crop stress and disease, and non-living bodies through sea-level rise, stronger cyclones, altered rivers and ocean acidification.

Anthropogenic Greenhouse Gas Emissions
Fossil fuel combustion, deforestation, and agriculture raise greenhouse gases; Andhra Pradesh’s aquaculture and Eastern Ghats deforestation notably increase methane and CO2 locally.
Land Use Changes and Agriculture
Deforestation in Seshachalam Hills reduces carbon sinks; livestock and chilli cultivation in Andhra Pradesh emit methane and nitrous oxide, intensifying warming.
Biodiversity Loss and Agricultural Stress
Rising temperatures disrupt habitats, threatening species like the Indian pangolin in coastal mangroves; drought in Rayalaseema causes crop failures and pest outbreaks.
Human Health and Livelihood Disruption
Heatwaves in Visakhapatnam increase heat-related illnesses; fisheries along Andhra Pradesh’s 974 km coast suffer from ocean warming and acidification.
Sea-Level Rise and Extreme Weather
Thermal expansion and glacial melt cause sea-level rise, leading to salinity ingress and land loss on Andhra Pradesh’s east coast; cyclones Hudhud and Titli exemplify increased storm intensity.
Hydrological Changes and Ocean Warming
Variability in Krishna and Godavari river flows affects irrigation; warming Bay of Bengal waters disrupt marine biodiversity and fisheries.
Forest Conservation and Carbon Sequestration
Strengthen CAMPA implementation in Andhra Pradesh to enhance forest cover and climate regulation.
Climate Resilience Measures
Promote sustainable agriculture and coastal protection to mitigate impacts on livelihoods and ecosystems.
