Over 100,000 years ago? I wonder what caused it then? Obviously we are having an impact but I think there are certainly other factors at play. |

Sometimes all it takes is a meteor strike, landing some place with lots of ice & snow.
They can carry massive amounts of energy, and generate alot of heat..... which can cause global riseing temps. and more importantly really high ones locally.
Once the energy disipates, a balance can be reestablished.
But for a periode, there can be alot of "melt" and higher sea levels, due to such a thing as say a meteor strike.
This time, we cant blame a giant hot peice of rock falling, for our raiseing global temptures.... or how much & how fast ice is melting.
Its just the greenhouse effect, of us polluting.
Supposedly this last big meteor strike some 12,900 years ago, is why USA + Canada isn't under mountains of snow right now.
If you had a time machine and could go back 14,000 years in time, you would see a much colder north america & canada.
