Simple explanation of greenhouse effect - right or wrong?

AI Thread Summary
The discussion centers on the greenhouse effect, emphasizing that greenhouse gases (GHGs) warm the Earth's atmosphere by absorbing and re-emitting thermal radiation. The basic mechanism involves solar radiation being absorbed by the Earth's surface, which then warms the atmosphere through contact and radiation. While some participants argue about the role of back radiation, the consensus is that GHGs contribute to increased atmospheric temperatures by trapping heat. The analogy of a greenhouse is used to illustrate how GHGs allow sunlight in while preventing some heat from escaping. Overall, the conversation highlights the complexity of the greenhouse effect while acknowledging its fundamental principles.

I have studied the data myself and the warming trend detected has stopped

You forgot to tell the ice caps. Please tell them soon.
