Can you remove location info from Google?

Hi. I'm having trouble removing the auto-detected location from the left side of google search.

I have tried turning off the geo:locate through mozilla firefox as well as revoking permission for them to supply that information to google.

It is not possible to amend the location to 'Earth' or '-'

I can alter the location to my country but only with cookies turned on, as soon as I wipe my history or turn the cookies off it switches back to the original location,

This happens whether I am signed into igoogle/gmail etc.

Does anyone know if it is possible to disable this feature?
