The natural greenhouse effect is a process where certain gases in the atmosphere trap heat, warming the Earth's surface to a habitable temperature. The enhanced, or anthropogenic, greenhouse effect refers to the additional warming of the Earth's surface and lower atmosphere due to the increase in greenhouse gas concentrations caused by human activities, primarily the burning of fossil fuels, deforestation, and industrial processes. D. Maintenance of ecosystem Ans: D Biodiversity contributes to ecosystem services such as pollination, soil formation, climate regulation, nutrient cycling, and pest control, which are vital for human survival and well-being.
As compared to natural greenhouse effect, the enhanced greenhouse effect refers to increase in average surface temperature of the Earth due to

- Read the following statements about the climate change. Identify the correct ones. 1. As per the latest report of IPCC, Climate Change is happening at a rapid pace. 2. The role of anthropogenic activities are extremely likely responsible for the climate change. 3. Change in Climate would promote insect-borne diseases and lead to shift in climatic boundaries.
- IPCC reports consistently indicate that climate change is occurring at an unprecedented and accelerating rate, making statement 1 correct. 2. The Intergovernmental Panel on Climate Change (IPCC) reports unequivocally state that human activities, primarily the emission of greenhouse gases, are the dominant cause of observed warming since the mid-20th century, making statement 2 correct. The language used in the latest reports is very strong ("unequivocal" or "extremely likely"). 3. Climate change is projected to alter temperature and precipitation patterns, which can expand the geographical range and seasonality of many disease vectors (like mosquitoes and ticks), thus potentially promoting insect-borne diseases (e.g., malaria, dengue). It also causes shifts in climatic zones and biomes, leading to shifts in climatic boundaries, making statement 3 correct. 3. At present which country is the maximum emitter of carbon dioxide ?
