A. History of COPs

B. Main causes of global warming

C. Main goals of this year’s COP

In 1994, the UN decided to bring together world leaders for an annual event, known as COP or ‘Conference of Parties’, to discuss climate change. This year’s conference will review what has been achieved and discuss the key goals.

The first goal is to limit the global temperature rise to 1.5°C. This will require reducing global CO, emissions by 50 per cent by 2030, and by 2050 achieving a balance between the greenhouse gases released into the atmosphere and those removed from it.

The second goal is to reduce the use of coal, whichis the dirtiest fuel and biggest source of planet-warming CO2 emissions. Countries will have to stop building new coal plants and switch to clean sources of energy.

The third goal is to end deforestation. Forests remove CO2 from the atmosphere and slow global warming. But when they are cut down or burnt, they release the carbon stored in the trees into the atmosphere as CO2. Stopping deforestation is, therefore, an effective solution to climate change.

The last key goal is to reduce methane emissions. Methane is a greenhouse gas that is more powerful than CO2 at warming the earth. It is responsible for nearly one-third of current warming from human activities. Methane comes from farming activities and landfill waste. The production and use of coal, oil, and natural gas also release methane.

This conference is very important because this is the best last chance we have to slow global warming. World leaders, climate experts, organisations, and national representatives will carefully discuss these goals and agree on how to make global progress on climate change.

REDUCING THE ENVIRONMENTAL IMPACT OF FARMING

Farming provides us with the food that we eat every day. But farming activities also have a strong warming impact on the global temperature. The good news is that experts have already started thinking about how to reduce it.

Raising farm animals like cows, goats, and sheep makes the planet hotter. There are billions of them and they release methane, a greenhouse gas that is much more dangerous than carbon dioxide. That is why scientists are developing methane-catching face masks for cows. They are intended to reduce methane emissions by up to 50 per cent per cow.

Another farming activity that heats the atmosphere is growing rice. According to research, emissions from rice farms have the same warming effect as about 600 coal plants. Flooded rice fields also make it easier for soil bacteria to produce greenhouse gases. New farming methods have allowed rice to grow well in drier fields, limit the amount of greenhouse gases, use less water, and produce better crops.

In addition, land-use increases the global temperature. Plants and trees use CO2 to grow and store large amounts of carbon underground. Cutting down or burning forests to create farm fields and land for feeding animals releases tonnes of carbon dioxide and other greenhouse gases into the atmosphere every year. Luckily, many countries and world leaders have agreed to protect the forests and end deforestation.

In short, there are some positive signs that farmers can meet the environmental challenges. However, although the impact of farming on the global temperature has been reduced, there is still much to do.

Câu 35 :

What we can do every day to help limit global warming?

(Chúng ta có thể làm gì hàng ngày để giúp hạn chế sự nóng lên toàn cầu?)

Work in groups. Carry out a survey to find out how people in your area are reducing the negative impact of their daily activities on the environment and trying to limit global warming.

(Báo cáo kết quả khảo sát của bạn trước lớp.)

The report should include the following points:

(Báo cáo nên bao gồm các điểm sau)

• what their daily activities used to involve, e.g. driving to work

(những hoạt động hàng ngày của họ từng bao gồm những gì, ví dụ: lái xe đi làm)

• how these activities affect global warming, e.g. releasing carbon dioxide emissions

(những hoạt động này ảnh hưởng như thế nào đến sự nóng lên toàn cầu, v.d. giải phóng khí thải CO2)

• what people do to reduce their environmental impact, e.g. cycling to work

F. Cows, methane, and global warming

Methane-catching masks for cows

1. __________

There are more than one billion cows in the world, and cow farming is a large source of methane emissions. This colourless and odourless gas is much more powerful than CO2 at warming the earth.

2. __________

Farmers and companies are developing solutions for decreasing cows’ methane emissions. In Canada and Brazil, farmers started adding a special ingredient to their animals’ feed to reduce cows’ methane production. In New Zealand, scientists are working on a vaccine that can cut methane emissions. Rather than stopping methane emissions, a UK company has designed face masks to catch the gas before it is released.

3. __________

The masks will allow cows to continue their normal diet, but will turn methane into CO2 and water. They can fit comfortably on the cow’s head and can be adjusted to different head sizes. Sensors on the masks can notice when methane comes out of the cow’s mouth and provide the percentage of the gas. This information can also be useful for farmers who can use it to identify the early signs of disease. For example, if a cow eats less, but produces more methane than usual, it may have a health problem.

4. __________

It is predicted that the need for beef and dairy products will go up in the coming years. The company developing the methane-catching masks hopes that farmers will start using their invention, which will slow down global warming.
