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 particularcarbon dioxide (CO2). Car emissions are a major problem, but the truth is that more CO2 comes from the energy used at home. Theaverage household creates around five and a half tonnes of CO2 a year, and it is that same CO2 which is changing the climate anddamaging the environment.(2) CO2 and various other gases wrap the earth in an invisible blanket helping to prevent heat from escaping. Without thisgreenhouse 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 theindustrial revolution began around 200 years ago, people have been burning increasing amounts of fossil fuels, thus releasing moreCO2 and other greenhouse gases in the process. This has increased the heating effect of the blanket, trapping more of the sun'senergy inside the Earth's atmosphere. In turn the Earth's temperature has increased more rapidly in a shorter period of time than ithas for thousands of years.(3) In 2008, the total UK CO2 emissions were 533 million tonnes. 27% (144 million tonnes) of those emissions came from theenergy used to heat, light, and power homes. Transport emissions caused by passenger cars, buses, mopeds and motorcyclesaccounted for a further 16% (87 million tonnes) of the UK's CO2 emissions. These figures show that a significant amount of CO2results from ordinary citizens' carbon footprint in their daily activities and lifestyle.(4) The effects of climate change can be seen all around us. Weather patterns are becoming more and more fractured anduncertain, and over the last century trends in warm weather have become increasingly common. In the UK in the last 40 years,winters have grown warmer, with much heavier rainfall. One of the clearest shifts over the last 200 years is towards summers thatare hotter and drier, causing pervasive water shortages. Recent years have been the hottest since records began, and during August2003, the hottest ever outdoor temperature in the UK was recorded - 38.5°C.
