Explanation
Natural forcings include changes in solar output and volcanic eruptions (which inject sulphate aerosols into the stratosphere and cool the climate). Increased greenhouse gases, land-use change and tropospheric aerosols are mainly anthropogenic forcings.प्राकृतिक प्रणोदनों में सौर विकिरण में परिवर्तन और ज्वालामुखी विस्फोट (जो समतापमंडल में सल्फेट एरोसोल पहुँचाकर जलवायु को ठंडा करते हैं) शामिल हैं। बढ़ती ग्रीनहाउस गैसें, भूमि उपयोग परिवर्तन और क्षोभमंडलीय एरोसोल मुख्यतः मानवजनित प्रणोदन हैं।More People, Development and Environment questions
