Agree with Nick..... learn some science
So, is the average heat flow on Iceland 200W/m^2???
Here are a few simple thought experiments:
1. Iceland has glaciers. It is not hard to find photos of Iceland showing snow on the ground, apparently somewhat stable. How do these facts relate to the hypothesis of 200W/m2 heat flow?
2. A queen-size electric blanket apparently draws about 200W when heating. So about 50W/m^2. Think about how warm an electric blanket gets if you have it set to "MAX". Think about how much warmer it would be if you piled four such blankets on top of each other. Do you think it is likely the ground over the entire island of Iceland is that warm. Refer to thought experiment #1 if needed.
