Earth's Changing Climate Review

Front

What is the primary reason for the increase in carbon dioxide levels in the atmosphere today?

Back

The primary reason is the increase in fossil fuel combustion due to a growing population.

Front

What is a significant source of methane emissions in the atmosphere?

Back

A significant source of methane emissions is livestock, particularly from cows.

Front

What constitutes weak evidence in climate change studies?

Back

Data from a glacier for only the last 2 years is considered weak evidence.

Front

What does an increasing trend in climate data typically indicate?

Back

An increasing trend in climate data typically indicates a rise in temperature or greenhouse gas concentrations.

Front

Can human actions influence the rate of climate change?

Back

Yes, human actions can significantly influence the rate of climate change.

Front

What are fossil fuels, and why are they important in climate change?

Back

Fossil fuels are natural substances like coal, oil, and natural gas that release carbon dioxide when burned, contributing to climate change.

Front

What role do greenhouse gases play in Earth's climate?

Back

Greenhouse gases trap heat in the atmosphere, leading to a warming effect known as the greenhouse effect.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in Earth's atmosphere trap heat, keeping the planet warm.

Front

What are some human activities that contribute to climate change?

Back

Human activities such as burning fossil fuels, deforestation, and industrial processes contribute to climate change.

Front

What is the significance of long-term climate data?

Back

Long-term climate data is crucial for identifying trends and making predictions about future climate conditions.
