Yes: most mainland Norway ice was gone during the holocene climatic optimum (9–6 thousand years ago), and glaciers recovered since then (until approx the 20th century, when deglaciation started accelerating again).
replyThe climate is varying in long cycles, and the deglaciation 20 thousand years ago (last glacial maximum) was driven by a spike in summer temperatures, and this peak has already long passed. Ice ages and interglacial periods have a certain momentum to them, so it takes more than just that to go back to full ice age..
Yes, the early Neolithic was warmer than modern era.
replywrong: IPCC AR6 puts the warmest Holocene stretch (~6.5 ka) at about 0.2-1°C above 1850-1900. 2011-2020 already beat that
replyNo, it's not wrong or we wouldn't be finding 5K year old instruments underneath melted glaciers as this article's evidence shows. And ice core samples from Greenland and Antarctica support this.
replyWithout taking a position I will point out that your stated reasoning doesn't hold due to how much momentum these systems have and how slowly they respond. It seems entirely plausible that this outcome would still have happened if temperatures had plateaued several years ago.
replyDo you also wait until the inside of the meat is the temperature you want before taking it off the grill, then are later surprised when it is overcooked?
replyWhatever you put in the glacier the glacier gives back to you. Anything you leave there ends up at the bottom of it in the moraine.
