The man is most likely suffering from chromoblasomycosis, which is a long-term fungal infection of the skin and subcutaneous tissue. Hope this helps!

The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. The absorbed energy warms the atmosphere and the surface of the Earth.
