Question

Which of the following is not a cause of global warming by enhanced greenhouse effect?

• A. carbon dioxide gas
• B. other green house gases
• C. additional heat entrapment
• D. all of these

Answer 1

The correct option is D all of these

Greenhouse gases (carbon dioxide, methane, water vapour, etc) trap the Sun's heat inside the atmosphere. Forests and trees produce food by photosynthesis which uses carbon dioxide as one of the raw materials. Thus, they do not contribute to an enhanced greenhouse effect. The percentage of greenhouse gases increase in our atmosphere due to excessive usage of fossil fuels. This is the main cause for global warming and climate change.
