Human Activities which Contribute to an Increase in Greenhouse gases in the atmosphere 

Some human activities increase the amounts of greenhouse gases, such as carbon dioxide and methane in the atmosphere.

Human activities that increase the amounts of carbon dioxide include the burning of fossil fuels and deforestation. Cattle farming and rice production are significant factors in the increase of methane.

Based on peer-reviewed evidence, many scientists believe that human activities will cause the temperature of the Earth’s atmosphere to increase at the surface and that this will result in global climate change.

However, it is difficult to model such complex systems as global climate change.

This leads to:

- simplified models

- speculation and opinions presented in the media that may be based on only parts of the evidence and which may be biased.
