The change in the global surface temperature between 1850 and the end of the 21st Century is likely to exceed 1.5°C, most simulations suggest. The WMO says that if the current warming trend continues, temperatures could rise 3-5°C by the end of this century. Temperature rises of 2°C had long been regarded as the gateway to dangerous warming. More recently, scientists and policymakers have argued that limiting temperature rises to 1.5°C is safer.

An Intergovernmental Panel on Climate Change (IPCC) report in 2018 suggested that keeping to the 1.5°C target would require “rapid, far-reaching and unprecedented changes in all aspects of society”. The UN is leading a political effort to stabilise greenhouse-gas emissions for as long as we continue to emit greenhouse gases, temperatures will continue to rise. China emits more CO2 than any other country. It is followed by the US and the European Union member states, although emissions per person are much greater there. But even if we now cut greenhouse-gas emissions dramatically, scientists say the effects will continue. Large bodies of water and ice can take hundreds of years to respond to changes in temperature. And it takes CO2 decades to be removed from the atmosphere.

As more CO2 is released into the atmosphere, uptake of the gas by the oceans increases, causing the water to become more acidic. This could pose major problems for coral reefs. Global warming will cause further changes that are likely to create further heating. This includes the release of large quantities of methane as permafrost - frozen soil found mainly at high latitudes - melts.

Responding to climate change will be one of the biggest challenges we face this century. As the world warms, more water evaporates, leading to more moisture in the air. This means many areas will experience more intense rainfall - and in some places snowfall. But the risk of drought in inland areas during hot summers will increase. More flooding is expected from storms and rising sea levels. But there are likely to be very strong regional variations in these patterns.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 25 to 29.

Imagine a city that’s steeped in history. Now think of a city that is vibrant and modern. Maybe you think no city can be both, but you’d be wrong. Istanbul, the most well-known city in Turkey, manages to combine both ancient traditions with a lively, contemporary feel.

Being the only city in the world that is situated on two continents, Istanbul is clearly something special. On the legendary Silk Route that once linked Asia and Europe and the capital of many different civilisations in the past, Istanbul has a cultural diversity that few cities can offer. It remains to this day a welcoming place for thousands of people that come to visit it each year.

Before you start thinking the city is touristy, Istanbul has more than just historic monuments. Alongside its fabulous mosques and palaces, you can find cool art galleries and trendy cafes. In fact, there is so much variety that you can always find something that suits your mood. If shopping is more your scene, you can head to the Grand Bazaar with its thousands of stalls, or visit the many shopping centres and fashion stores. At night the streets are bustling with life and you’re spoilt for choice for places to eat and drink.

Quite frankly, Istanbul should be on any list of the world’s most liveable cities for its unique beauty and character. But don’t just take my word for it. Come and see for yourself. You might just end up staying, like many have before!

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 44 to 50. 

   Los Angeles dancer, Brian Perez, was eating out with his friends one evening when suddenly everyone went quiet. To his horror, he saw that the reason for this was that people were checking their phones. Realising he had to do something to stop this, Brian made a rather daring suggestion. What if they all put their gadgets in a pile in the middle of the table until they had finished the meal? If anyone picked up their phone, that person would have to pay the whole bill. And so, it is said, the game of 'phone stacking' was bom.

   The necessity for action like this highlights a major problem in today's society: our inability to disconnect from technology. But while Brian's idea deals with the obsession in a social context, measures also need to be taken at home. Some people drop their smartphones into a box the moment they arrive home, which gives them the chance to interact with the people they live with. The fact that the phone cannot be heard - it is on silent - nor seen - the flashing lights are hidden by the box - means that they are no longer tempted to use it

   A less drastic solution is to ban electronic devices at certain times of day when the whole family is likely to be together, for example at meal times. This can be hard for everyone, from teenagers desperate to text friends to parents unable to switch off from work. On a normal day, however, dinner takes less than an hour, and the benefits of exchanging opinions and anecdotes with the rest of the family certainly makes up for the time spent offline. 

   Taking a break from technology is one thing, but knowing when to turn off a device is another. Time seems to stand still in the virtual world, and before you know it, you find that it is three o'clock in the morning. This is where a digital curfew comes in handy, a set time when all devices must be put away. Evenings without technology are usually nice and peaceful and make a more agreeable end to the day. 

And then it's time for bed. One of the best ways of ensuring you can sleep at night is to ban electronic devices altogether from the bedroom. Lying next to a machine bursting with information is far from relaxing, and the sounds it emits during the night can easily wake you up. With technology out of the room, a line has been drawn between daytime and sleep time, which enables us to switch off ourselves and drift off to sleep.
