This is because the amount of sunlight the reaches the equator changes very little, although the temperatures do vary somewhat during the rainy season. Measurement: The average surface temperature on Earth is approximately 14Â°C; but as already noted, this varies.
If there were no greenhouse effect, the Earthâs average surface temperature would be a very chilly -18Â°C (0Â°F) instead of the comfortable 15Â°C (59Â°F) that it is today.lobal warming is the unusually rapid increase in Earthâs average surface temperature over the past century primarily due to the greenhouse gases released as people burn fossil fuels.
