(Hội nghị về biến đổi khí hậu của Liên hợp quốc)
Work in pairs. Look at the pictures and discuss the environmental problems you see.

Picture A: Deforestation is a significant environmental issue that occurs when forests
are cut down for various reasons. This can result in a loss of plant and animal species,
soil erosion, and climate change. Deforestation can negatively impact human
communities that rely on forests for their livelihoods. It is important to take action to
prevent deforestation and protect our forests for future generations.
Picture B: CO2 emissions are a significant environmental problem that occurs when
large amounts of carbon dioxide are released into the atmosphere from human
activities. This contributes to the greenhouse effect and global warming, which can
have serious consequences such as rising sea levels and more extreme weather events. Bài 2
Read the article and choose the best title for it.
(Đọc bài báo và chọn tiêu đề tốt nhất cho nó.) 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. Gợi ý đáp án

A. Global warming will be limited to 1.5°C.
B. Global CO, emissions will increase.
C. Countries will switch to clean energy.

Work in groups. Discuss the following question.
(Thảo luận câu hỏi sau.)
What should we do to reduce global warming?
(Chúng ta nên làm gì để giảm sự nóng lên toàn cầu?) Gợi ý đáp án
There are several actions that individuals and governments can take to reduce global warming:
● Reduce energy consumption: One of the main sources of greenhouse gas
emissions is the burning of fossil fuels to produce energy. We can reduce
energy consumption by turning off lights and appliances when not in use, using
energy-efficient light bulbs and appliances, and reducing the use of air conditioning and heating.
● Use renewable energy sources: Renewable energy sources such as solar, wind,
and hydropower emit little to no greenhouse gases. Governments can invest in
renewable energy infrastructure, and individuals can install solar panels on
their homes or participate in community solar programs.
● Reduce, reuse, and recycle: The production of goods and the disposal of waste
are also sources of greenhouse gas emissions. By reducing the amount of waste
we generate, reusing products as much as possible, and recycling materials, we
can reduce emissions and conserve resources.
● Plant trees and conserve forests: Trees absorb carbon dioxide from the
atmosphere, so planting trees and conserving forests can help reduce greenhouse gas emissions.
● Support climate-friendly policies and actions: Governments can implement
policies and actions that promote clean energy, reduce emissions, and protect
the environment. As individuals, we can also support these policies and take
action to reduce our own emissions.
