Type-II Diabetes, or non insulin-dependent diabetes mellitus (NIDDM) involves a disrupted insulin signaling mechanism [broken]. There is usually a problem with insulin receptors on cells, and not so much the insulin itself (or pancreas). Sometimes the cause of type-II is referred to as "insulin resistance."
Global warming is a long-term rise in the average temperature of the Earth's climate system. And the greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without its atmosphere.
