What was the increase in atmospheric CO₂ from 1900 to 2000?

Back

Atmospheric CO₂ levels increased from 290 ppm to 370 ppm.

Front

How do you calculate the rate of change in CO₂ levels?

Back

Rate of change = (Final value - Initial value) / Number of years.

Front

What is the primary purpose of climate models?

Back

Climate models are used to simulate Earth's systems interactions and predict future climate scenarios.

Front

Why are climate models important for scientists?

Back

They help analyze current conditions and make forecasts about future climate trends.

Front

What is the atmosphere?

Back

The atmosphere is the layer of gases surrounding Earth, essential for life and weather.

Front

What role do volcanic eruptions play in climate?

Back

Volcanic eruptions release gases and ash into the atmosphere, which can affect climate patterns.
