1.1 I am familiar with the vocabulary

What is the main cause of current climate change according to the IPCC?

• Natural variations in the solar cycle

• Volcanic activity

• Changes in the Earth’s orbit

• Human activities, especially the burning of fossil fuels

What is the greenhouse effect?

• A mechanism that cools the Earth naturally

• A natural phenomenon where certain gases trap heat in the atmosphere

• process caused only by human-made gases

• A system that blocks sunlight from reaching the Earth

1. What global temperature increase limit is targeted by the Paris Agreement?

• Below 3°C

• Exactly 2°C

• Well below 2°C, ideally 1.5°C

• Below 1°C

Which planetary boundary was most recently crossed (May 2022)?

• Ocean acidification

• Biosphere integrity

• Aerosols load

• Freshwater cycle

What makes planetary boundaries critical for climate policy?

• They are mostly political concepts

• Once crossed, they may lead to irreversible environmental change

• They change every year

• They only apply to high-income countries

What is the IPCC?

• An organization that conducts its own experiments

• A think tank led by private companies

• A lobbying group for green technologies

• A UN scientific body assessing climate research

What does the Paris Agreement’s 5-year cycle mean?

• Countries revise their emissions annually

• Countries must submit more ambitious climate plans every five years

• Targets are fixed permanently

• Rich countries must update targets only every 10 years

Why should climate, biodiversity, and human systems be studied together according to the IPCC?

• To simplify reporting

• Because climate acts independently from ecosystems

• To avoid double counting emissions

• Because they form integrated, interdependent systems
