CLEAN : Greenhouse gas levels reach new record high: UN WMO Secretary-General

The video discusses the ongoing impact of climate change, highlighting the persistence of its effects over centuries. It reports record levels of greenhouse gases like carbon dioxide, methane, and nitrous oxide. Despite political support for climate mitigation, concrete actions are lacking, leading to a projected warming of 2.5 to 3 degrees Celsius. The video emphasizes the importance of choosing a sustainable future to limit warming to 1.5 degrees Celsius.

What is the main theme discussed in the first section of the video?

• The rapid changes in climate factors

• The immediate effects of climate change

• The comparison of climate change with COVID-19

• The role of technology in climate change

Which greenhouse gases have reached record levels according to the video?

• Hydrogen, helium, and oxygen

• Helium, neon, and krypton

• Carbon dioxide, methane, and nitrous oxide

• Oxygen, nitrogen, and argon

What is the current trajectory of global warming mentioned in the video?

• 3.5 to 4 degrees

• 4.5 to 5 degrees

• 2.5 to 3 degrees

• 1.5 to 2 degrees

What could be the potential temperature increase by the end of the century if resources are used without limits?

• 5 degrees

• 2 degrees

• 3 degrees

• 4 degrees

What is the optimistic target for limiting global warming with successful mitigation?

• 2 degrees

• 2.5 degrees

• 1 degree

• 1.5 degrees
