can humans survive another ice age? Honestly...Many Alaskans, Many Canadians, Fins, Swedes, Russians, etc...from the north of north won't find it a big ordeal...in fact the climatic pendulum swinging back would be a welcome blessing... I know until I moved to the pacific coast...my dog and I used to toboggan, snow shoe, cross country ski, and ice fish...in daily winter temperatures from -20 to -40....quite happily... only people suffering from an ice age will be the city people...really... Northern cities will hurt the most...and become abandoned.. wheat and other crops produced in a huge swath of the northern hemisphere would be null... mass migrations would occur except for those who have no problem with such weather... wildlife wouldn't suffer ...they would do fine.... but the timeline to a serious ice age would be awfully long to truly encroach and affect humanity...it would take generations upon generations to really start showing ... It may in fact happen considering how out of whack the planet is..but it would take a long time to build up steam and impact seriously... Serious "cold snaps" where the frozen ground gets so cold it cracks...utters nasty "bangs"..and "groans" (really truly...it does groan...) ...or Ice storms...we Canadians have been dealing with for a long time now...a nasty side effect... more devastating in it's sharp immediate impact... than any ice age...the damage to crops and trees ...to power lines and infrastructure...and the time to recover measured in weeks ...or even months...for some areas....is truly horrible... Hm...in fact...I think we have already gone through at least one or two recorded mini ice ages already...years ...decades..with far colder than normal temps. Interestingly...the data is also in..that the climate change we are experiencing isn't something that we just recently started... It started during the industrial revolution... One thing for sure.... We as a species need to fix how we interact with our environment... or flee it into some generated micro-verse (it being the most energy cost efficient method..than fleeing off planet..or some other method...such as changing the biology of life here to adapt...) else we may end up being an example of the Fermi paradox gone bad...
