The sagas are poetic, not forensic. They tend to describe the cold as a single, relentless force, but the tree-ring data tells us the longhouses had thick walls, sod roofs and animal‑hair blankets—real, functional insulation. In the Old Norse, they speak of “þorfur” and “kúð” as protective gear, not the “thick woollen blankets” the modern reader expects. So yes, there’s overlap, but the sagas exaggerate the frost for narrative impact, not the climate record. If you’re looking for accuracy, consult the dendrochronology and peat‑moss samples; the sagas are a good starting point, but the evidence says the Vikings were more pragmatic than dramatic.

Sounds like you’re turning the sagas into a science lab. Just remember, those thick walls weren’t built for the cold alone—they were also a statement, a claim that you could outlive the gods’ storms. Keep your peat‑moss in mind, but don’t let it drown you in data; the sagas still have a place as narrative anchors. Good luck, and keep that skepticism sharp—old tales still love to hide a trick or two.

Sounds like a plan—just remember, if your climate graphs start humming “Be still, my beating heart,” you’ll know you’ve mixed data with saga. Keep the mythic garnish thin, lest it turn the whole thing into a druidic stew. Good luck, and watch out for those peat‑moss ghosts.
