The Arctic was warmer in the 1930's than the late late twentieth century, and it was ice free on occasion. https:// hockeyschtick.bl ogspot.com/ 2012/07/ nasa-data-shows- arctic-was-warm er-in.htmlhttps:// judithcurry.com/ 2013/04/10/ historic-variati ons-in-arctic-s ea-ice-part-ii- 1920-1950/ but we do know that there was melting in the Arctic prior to the modern era of higher carbon dioxide.

BTW we don't have accurate data going back  beyond the '70's. See https:// judithcurry.com/ 2013/04/10/ historic-variati ons-in-arctic-s ea-ice-part-ii- 1920-1950/ but we do know that there was melting in the Arctic prior to the modern era of higher carbon dioxide.

It should be pointed out that lightning strikes in the Arctic are rare but they do happen on occasion. Given the situation up there, with a moving north magnetic pole and a variation between high and low pressure zones as is the case now, we should expect lightning.
