VOICED : Reducir gases de efecto invernadero mision en cumbre de Ruanda

The video discusses a summit in Kigali where representatives from nearly 200 countries aim to reach an agreement to reduce greenhouse gas emissions, specifically hydrofluorocarbons (HFCs). These gases, used in refrigeration and aerosols, significantly contribute to global warming. The goal is to align with the Paris Agreement to keep global temperature rise below two degrees Celsius. The video also covers the history of HFCs, introduced in the 1990s to protect the ozone layer, but later found to be more harmful than CO2 in trapping heat.

What is the primary objective of the summit held in Kigali?

• To promote the use of aerosols

• To discuss global trade policies

• To reduce greenhouse gas emissions

• To increase the use of hydrofluorocarbons

What is the main goal of the Paris Agreement mentioned in the video?

• To eliminate all greenhouse gases by 2025

• To reduce the use of fossil fuels by 50%

• To keep global temperature rise below two degrees Celsius

• To increase industrial production

What potential impact does the Kigali agreement aim to achieve by the end of the century?

• Increase global temperatures by one degree

• Reduce global warming by half a degree

• Eliminate all carbon emissions

• Double the use of renewable energy

When were hydrofluorocarbons introduced, and for what initial purpose?

• In the 2000s, to improve energy efficiency

• In the 1980s, to reduce air pollution

• In the 1990s, to protect the ozone layer

• In the 1970s, to enhance industrial growth

How do hydrofluorocarbons compare to carbon dioxide in terms of their impact on the atmosphere?

• They are more harmful in trapping heat than carbon dioxide

• They have no impact on the atmosphere

• They are equally harmful as carbon dioxide

• They are less harmful than carbon dioxide
