One geoengineering solution to prevent global warming is to increase Earth’s albedo by adding particles to the stratosphere that can reflect sunlight or increasing cloudiness over the oceans. By how much does the albedo have to change to reduce the Earth’s temperature by 1 degree K? What is the corresponding energy difference in W/m2? Assume a one layer atmosphere modelthat is transparent to visible light and opaque to surface emitted IR, a solar constant of 1360W/m2 and an initial albedo of 0.30.

PART 1: Reading: Read the text below. Then answer the questions that follow. (1) Around 45% of the UK's carbon dioxide emissions come from the energy people use every day - at home and when they travel. In order to generate that energy, fossil fuels (coal, oil, and gas) are burnt, and these produce greenhouse gases - in particular carbon dioxide (CO2). Car emissions are a major problem, but the truth is that more CO2 comes from the energy used at home. The average household creates around five and a half tonnes of CO2 a year, and it is that same CO2 which is changing the climate and damaging the environment. (2) CO2 and various other gases wrap the earth in an invisible blanket helping to prevent heat from escaping. Without this greenhouse effect, the average temperature on Earth would be around -18°C, compared with the current average of around +15°C. The composition of this blanket of gases has remained relatively constant for many thousands of years. However, since the industrial…
