And I’m not referring to that, the big concern from climate researchers comes from the ice in Greenland and over the antarctic, that is the ice over ground. I’m also taking into account the ice that is close to shore, warming water melts the underside of the floating fringes of the Greenland ice sheet.
We already know it is not the the oil-rag fire. Again, if you think there are other better causes for the ice loss than the current warming caused by human activities post them; there is clearly already a good answer for your OP, the warming in last decades is clearly not natural, ignoring that answer is reaching very silly levels.
