Laws on ation. Using the energy model sketched below plus concepts oI energy nservation, consider the impact of a dirty war on the global energy. To start, assume that the pact of this war has created an atmosphere that absorbs 75% of the incoming sunlight, while e albedo is reduced to nearly 20%. Let's assume that Earth's ability to reflect incoming solar diation is negligible. The Earth's surface radiates 240 W/m2, all of which is absorbed by the nosphere. Assuming that Earth can be modeled as a blackbody emitter and incoming/outgoing ergy as shown in the schematic, find the following quantities: a) The "nuclear winter" temperature [°C] of the surface of the Earth b) X, the rate [W/m2] at which radiation is emitted from the atmosphere to space c) Y, the rate [W/m²] of absorption of short-wavelength solar radiation at the Earth's surfac d) Z. the rate [W/m21 at which the atmosphere radiates energy to the Earth's surface
