TED-Ed: Is the weather actually becoming more extreme? | R. Saravanan

The video explores the increase in extreme weather events from 2016 to 2019, questioning whether these are due to bad weather or climate change. It explains the differences between weather and climate, how they are predicted, and the challenges in forecasting due to weather's chaotic nature. Climate predictions rely on boundary conditions, which are more stable. The video highlights the impact of climate change, driven by human activity, on increasing extreme weather events.

What years did meteorologists observe record-breaking heat waves and wildfires?

• 2016 to 2019

• 2000 to 2003

• 2010 to 2013

• 2020 to 2023

How do meteorologists define weather?

• Long-term climate patterns

• Average atmospheric conditions over a month

• Random atmospheric changes

• Conditions of the atmosphere at a specific time and place

What is the accuracy of weather predictions for the next week?

• 90%

• 80%

• 60%

• 50%

What are boundary conditions in climate predictions?

• Random atmospheric changes

• Daily temperature variations

• Constraints on climate and weather

• Current weather events

Why is weather considered a chaotic system?

• It is unaffected by small disturbances

• It follows a fixed pattern

• It is sensitive and hard to forecast perfectly

• It is predictable with high accuracy

What has been the impact of a 1-degree Celsius increase in Earth's surface temperature?

• No significant impact

• Decrease in extreme weather events

• Energy equivalent to one million nuclear warheads added to the atmosphere

• Stabilization of climate patterns

What is the scientific consensus on climate change?

• Climate change has no impact on weather

• Climate change is a natural process

• Human activity is accelerating climate change

• Climate is not changing
