The video features Dr. Jennifer Francis discussing the polar vortex, a weather phenomenon often misunderstood. She explains its true nature and how climate change, particularly ice loss in the Arctic, may be causing disruptions. The discussion highlights the scientific process of forming hypotheses and the distinction between weather and climate, emphasizing the impact of human activities on climate change.

What is the primary function of the polar vortex?

• To generate heat waves

• To control ocean currents

• To keep cold air contained over the Arctic

• To create hurricanes

How does the loss of Arctic ice contribute to the splitting of the polar vortex?

• It increases ocean salinity

• It absorbs more heat, affecting atmospheric patterns

• It decreases sea levels

• It strengthens the polar vortex

What is the current status of the hypothesis linking climate change to polar vortex disruptions?

• It is widely accepted and proven

• It is a new and developing area of research

• It has been completely disproven

• It is unrelated to climate change

How does the scientific community validate hypotheses about atmospheric phenomena?

• Through historical documents

• By observing animal behavior

• Through public opinion polls

• By conducting experiments and using climate models

What is the main difference between weather and climate?

• Weather is long-term, climate is short-term

• Weather is global, climate is local

• Weather is day-to-day, climate is long-term average

• Weather is predictable, climate is random

What analogy is used to explain the difference between weather and climate?

• Weather is like a river, climate is like an ocean

• Weather is like a mood, climate is like a personality

• Weather is like a storm, climate is like a breeze

• Weather is like a mountain, climate is like a valley

What human activity is primarily responsible for climate change?

• Increasing greenhouse gases

• Deforestation

• Overfishing

• Urbanization
