Understanding global warming – The greenhouse effect (simple)
Life on Earth would not exist without the natural greenhouse effect. However, the greenhouse gases produced by humans, such as carbon dioxide and methane, adversely intensify the greenhouse effect.
Information and ideas:
An albedo (the capacity of diffusely reflecting surfaces such as ice and snow to radiate back) of approx. 0.30 was assumed for the direct reflection of incident radiation with and without the atmosphere, since Earth is not an ideal black body.
The anthropogenically intensified greenhouse effect and changes in solar activity are the main causes of climate change! There is scientific consensus that both effects influence Earth’s climate.
