The temperature of the atmosphere goes down with about 6K/km, the further up we rise. Assume a temperature of the Earth Surface of 285K. A) Calculate the infrared radiation intensity if the typical cloud top is at 3km. B) Calculate the infrared radiation intensity if the typical cloud top is at 3.5km. C) Assuming a 70% global cloud cover, what is the warming effect of a rising-cloud-top feedback? Compare it with the ~3W/m2 imbalance due to global warming
