- 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 ?
