climate change theory
The theory of climate change is very new. In fact, scientists don't even call it a theory. But it meets the requirements. These are the things we know: 1 average global temperatures are rising, 2 greenhouse gases trap heat in the atmosphere, 3 CO 2 is released into the atmosphere when fossil fuels are burned, 4 CO 2 is a greenhouse gas, 5 more CO 2 in the atmosphere traps more heat so global temperature is rising. No information contradicts this theory, although some details have not been worked out. The theory is very effective at predicting future events, which are already taking place. This idea will be explored in detail in the chapter Atmospheric Processes .
