WHITE ROOFS FOR A BRIGHT FUTURE!

The effects of global warming are becoming more and more noticeable in years. A high number of floods, storms and heatwaves has resulted from the increasing levels of carbon dioxide (CO₂) and other greenhouse gases that do not allow the sun's heat to escape the Earth's atmosphere. However, a simple and quite promising idea has been suggested to help lessen the consequences of climate change.

Professor Steven Chu, a Nobel prize winner, suggested that painting our rooftops white would help the Earth's temperature to drop. Their idea is that if enough surfaces – rooftops, pavements, roads – are painted white, more sunlight will reflect off these surfaces and go back into space. This will help cool our planet down.

According to scientists, if rooftops and roads were painted white it would reduce the amount of CO₂ by billions of tonnes. Homes with white rooftops and cars that are painted white wouldn't absorb so much heat from the sun. This means that they would be cooler and people wouldn't have to turn on their air conditioners. We would save more energy and reduce the amount of CO₂ released in the atmosphere.

Although the idea of white rooftops has been welcomed by the scientific and environmental communities, there appear to be a few problems. One of these is the fact that the colour white will be too bright if it is painted on too many large surfaces. Another problem is that keeping the white surfaces in good condition for a long period of time would be too expensive.

Some people feel that though painting rooftops and pavements in light colours is good in theory, it is just a very small step to take towards reducing the Earth's temperature. What we must remember though is that there is not one solution to global warming. It's the combination of different methods that will protect the planet we live on.

Прочитайте следующий текст и решите, какие утверждения являются истинными (1 — Правда), ложными (2 — Ложь) или не указанными (3 — Не указано).

Ответ:

36

1) True

(С течением времени произошло увеличение количества углекислого газа.)

37

3) Not stated

(В тексте не указано, что покраска достаточного количества поверхностей в белый цвет могла бы охладить нашу планету на 2 °C.)

38

2) False

(Белые машины поглощают меньше тепла от солнца, чем другие машины, согласно тексту.)

39

3) Not stated

(Хотя идея профессора Чу была "встречена с одобрением" научными и экологическими сообществами, в тексте не говорится прямо, что она была "принята многими экспертами" без оговорок, поскольку затем упоминаются "несколько проблем".)

40

1) True

(В тексте говорится: "Некоторые люди считают, что хотя покраска крыш и тротуаров в светлые тона хороша в теории, это лишь очень маленький шаг к снижению температуры Земли... не существует одного решения проблемы глобального потепления.")
