Increase In Earth's Temperature, Is This The Reason?
Averaged over all land and ocean surfaces, temperatures warmed roughly 1.53°F (0.85ºC) from 1880 to 2012, according to the Intergovernmental Panel on Climate Change.
In the Northern Hemisphere, where most of Earth's land mass is located, the three decades from 1983 to 2012 were likely the warmest 30-year period of the last 1400 years, according to the IPCC.

While greenhouse gases are for sure to cause global warming, they alone are not the reason for increase in earth's temperature.
Just curious if the increase in earth's temperature is due of excessive mining (of all sorts) and not due to greenhouse gases.
Imagine boiling water in a container, on a stove, obviously with fire as source.
The container is only as much heated as it should be as long as it has enough water.
If you drain the water slowly and maintain the heat as it is, (which means there is not enough water / matter for the heat to get transferred to) the heat is then transferred to the container, which gets heated more compared to what it was before
Now if we compare this real world scenario to earth, the core where there is heat source is sufficient for all the matter above and below the earth to keep earth at the temp. at what it should be.
Now as we know if water is drained the container gets heated up, similarly, excessive mining is removing the matter from the earth and hence the heat is transferred to earth's outer surface from the core, and not from outside.
Hence the reason for earth's temp. to go up slightly by less than a degree in so many years,
which is also causing ice to melt and increase ocean levels.
