Question

Explain why the greenhouse effect leads to increased average global temperatures ​

Answer 1

Global warming is the unusually rapid increase in Earth's average surface temperature over the past century primarily due to the greenhouse gases released as people burn fossil fuels. ... Temperatures are certain to go up further. Despite ups and downs from year to year, global average surface temperature is rising.

Answer 2

The increase in trapped energy leads to higher temperatures at the earth's surface. ... Then the ground, clouds, and other earthly surfaces absorb this energy and release it back towards space as longwave radiation. As the longwave radiation goes up into the atmosphere, it is absorbed by the greenhouse gases.
