P2U2 02The Enhanced Greenhouse Effect and Global Warming

Front

What is the Enhanced Greenhouse Effect?

Back

The Enhanced Greenhouse Effect refers to the observed increase in global temperatures since the Industrial Revolution, attributed to human activities and increased greenhouse gas emissions.

Front

What human activities contribute to the Enhanced Greenhouse Effect?

Back

Burning fossil fuels, deforestation, cattle ranching, rice farming, using artificial fertilizers, and cement production.

Front

How do greenhouse gases affect Earth's temperature?

Back

An increase in greenhouse gases leads to more heat being retained, causing Earth's temperature to rise.

Front

Which countries are the largest contributors to CO2 emissions?

Back

In 2014, China and the United States were the largest contributors, accounting for 30% and 15% of global CO2 emissions respectively.

Front

What are the main sources of CO2 emissions?

Back

Burning fossil fuels, deforestation, agriculture, and cement production.

Front

What is the significance of the Industrial Revolution in global warming?

Back

The Industrial Revolution marked the beginning of a significant rise in global temperatures due to increased carbon dioxide emissions from burning fossil fuels.

Front

What percentage of atmospheric gases do greenhouse gases constitute?

Back

Greenhouse gases make up less than 1% of atmospheric gases.

Front

Why is the increase in greenhouse gases significant despite their small percentage?

Back

Changes in their concentration have a huge effect on the balance of natural processes.

Front

What sectors are dominant in CO2 emissions for major emitting countries?

Back

The 'Energy' sector is dominant in CO2 emissions for most major emitting countries.
