- Climate scientists use the Stefan-Boltzmann Law R=oT4 to estimate the change in the earth's average temperature T (in kelvins) that results from a change in the radiation R (in joules per square meter per second) that the earth receives from the sun. Here, o = 5.67 x 10-8 Js-'m-²K-4. Calculate d R/dt, assuming that T = 283 and 4 = 0.05 K/year.

Second, its thick clouds reflect 77% of all incident sunlight. Finally, its atmosphere is much more opaque to infrared light.

- The best solar panels currently available are about 19% efficient in converting sunlight to electricity. A typical home will use about 40. kWh of electricity per day (1 kWh=1 kilowatt hour; 1kW=1000J/s). Assuming 8.1 hours of useful sunlight per day, calculate the minimum solar panel surface area necessary to provide all of a typical home’s electricity.
