What is the Earth's mean temperature?

Currently it is 14.6 °C up from 13.9 °C 100 years ago. This is

the average over the whole planet over the entire year.

The average temperature on Earth is about 13oC. Highest recorded

has been 56.7oC and lowest -89oC. These temperatures are dry bulb


Most of the Earth is subject to heating and cooling by the

oceans and the atmosphere. Except for extreme locations on Earth

(deserts, poles), the temperature range is compatible with human

activities, falling in the range between -40° and +40° C (-40° to


Temperatures tend to be hotter near the equator, or when it is

summer at a given location. Ocean and air currents also affect the

range of temperatures. Climate change scientists estimate that

ever-increasing levels of manmade carbon dioxide could raise global

temperatures by up to 6 degrees C over the next 50 years.

Core Temperature

The temperature of the Earth is approximately 5500 degrees

Celsius at its center and heat continuously flows toward the

surface. The temperature of the Earth increased with its increase

in mass because the new size triggered an increase in its

gravitational force of attraction and caused the Earth to compress.

Some of the internal heat comes from radioactive decay.

Very hot in the centre, gradually cooling as you move to the outer

layers, pretty cool on the outside, coldest at the top and bottom

where the polar bears and penguins live, and nicest for sunbathing

right around the fattest part in the middle. Could you be a little

more specific?
