Excess Glacier melt isn't caused by the sun, since the sun's TSI hasn't risen enough to account for it AND TSI has been low for the last 13+ years. Possible cosmic ray increases can't account for the melt. Glacial melt isn't caused by solar cycles, since rising temperatures & the melt are way too quick to be accounted for by slowly shifting solar cycles. However, snappily rising man-made GHG, infra-red energy absorbing CO2, methane, oxides of nitrogen, SF6 & other GHGs have been rapidly rising in the atmosphere, mathematically accounting for excess heat being delayed in Earth's lower biosphere. In addition to the GHGs are the positive feedback mechanisms, initiated by excess GHGs, all again, accounting for excess heat.
Of course, Hersbird knew this already, because the above has been told it before. It just repeats a question it has offered before, that it thinks is rhetorical, is easily asked & sometimes not answered. Such is a common strategy by AGW deniers.
