CURSO DE BACHARELADO EM ENGENHARIA AMBIENTAL Componente Curricular: Língua Inglesa Prof. Julio Vila Nova Reading Activity Climate Change This article is about how the world’s climate is changing and the risks we face from more extreme weather. Before you read, look at some of the causes of climate change and extreme weather. Think about the possible effects these could have in the future. Cause 1: The world’s population is getting larger and more people are living in areas affected by extreme weather. Example effect: It may become more difficult to protect these people from the effects of extreme weather. Cause 2: Emissions of CO2 and other greenhouse gases are increasing. Cause 3: The average global temperature is rising. Cause 4: Extreme weather events such as drought and flooding are happening more often. Now, see if your ideas are mentioned in the article… Climate change: what next? The world can no longer say that global warming 'might' happen and climate change 'could' affect our future. A recent report by the Royal Society in the UK tells us that global warming is definitely happening and climate change will affect our future. The report warns that extreme weather events, such as floods, storms, and heatwaves, will happen more often and will affect more people as the earth’s population grows. The report’s main author Professor Georgina Mace said: “This problem is not just about to come… it’s here already." 14 of the 15 warmest years on record have all happened in the 21st century and 2014 was the hottest year ever – both in the UK and globally. But warmer weather does not always mean drier weather. In fact, the opposite is true. Look at the information about extreme weather events around the world in 2014: In September, parts of the Balkans received more than double the average monthly rainfall, and parts of Turkey saw four times more rain than normal. The town of Guelmin in Morocco was hit by more than a year's rain in just four days. Western Japan saw the heaviest August rain since records began. Parts of the western US suffered from long-term drought - as did parts of China and Central and South America. Interestingly, there were fewer tropical storms than usual – 72 were recorded in 2014 but the yearly average is 89. 12 major Atlantic storms struck the UK, bringing nearly double the usual rainfall. So, the world’s climate is changing. We are seeing higher temperatures and weather that directly affects our lives like heatwaves, drought, and flooding. But what effects could these weather events have on our future? And how might we prepare ourselves to face these extreme conditions? Professor Mace says preparation is the most important factor: “It is impossible for us to avoid the worst and most unexpected events. But it is not impossible to be prepared for an ever-changing world. We must organise ourselves right away." The Royal Society report advises all levels of society to prepare – from strategic planning by governments to local schemes by citizens to get ready for floods or heatwaves. To fight rising temperatures, the authors say cutting greenhouse gas emissions is essential. But they argue that it is not enough - governments will also need to do more. The simplest and cheapest way of preventing heatwaves, they say, is to protect existing green space. Other low-cost options are planting new trees, or painting roofs white to reflect the sun’s heat. This could have an important effect in cities which will get bigger as the earth’s population grows. Air-conditioning may help us stay cool but it produces emissions which will actually make our cities hotter. The authors also say generally higher temperatures might be a threat to economies and farming because temperatures could become too high for safe outdoor work. Some areas may experience many weeks when outdoor activity is limited because it will be simply too hot to go outside. Flooding will also increase, the report says. Large-scale engineering solutions like sea walls offer the best protection from coastal flooding - but they are expensive, and when they fail, the results can be disastrous. The ideal answer, the authors think, may be a combination of engineering solutions like walls and environmental solutions like protecting wet areas to allow the ground to absorb water. The authors also say that governments and companies will need to be prepared financially and may need to spend more money on preventing dangers. They say: “We must assess and evaluate risks accurately. If we don’t, companies might not take them seriously and investments will be poorly informed.” One author, Rowan Douglas, from the Willis Research Network, said this might be the most important recommendation of the report. PART 1 – VOCABULARY Number the meaning of the words found in bold in the text: (1) drought ( ) gases which are released into the atmosphere by factories, cars, and other machines. (2) right away ( ) a period of days or weeks when the temperature is very high and is dangerous for people. (3) strategic planning ( ) causing lots of damage or a very dangerous situation (4) schemes ( ) to take something inside, for example: a sponge absorbs water easily (5) heatwave ( ) a long period with no rainfall, which causes the ground to become very dry and can cause living things to die. (6) tropical ( ) making very careful plans so that particular things will happen at particular times or in particular situations. (7) emissions ( ) describes a geographical area where the weather is very hot and wet. (8) disastrous ( ) immediately; now (9) absorb ( ) plans that organisations develop to give a particular service to a group of people PART 2 – Comprehension 1.
