A nuclear winter is caused by many detonating nuclear weapons and not a volcano. This would be a volcanic winter. Also the climatic effects are comparable.
The little ice age was from 16th century to the mid 19th century as cause of less sun activity and more volcano activity.

To me, the interesting thing is that most scientists and climatologists seem to agree that the earth is actually in a fairly temperate and calm period between major ice ages. So even if we are warming the planet slightly, aren't we actually helping forestall the eventual and inevitable next ice age?
(I'm not saying man has no effect, obviously we do, but in the case of Global warming, I'm not sure we are the sole or even main culpret-)
Thoughts?

There are indicators that mankind has warmed the last Ice Age (not the Little Ice Age) that should have happened so that the temperature didn't fall.
Isn't it alarming that an Ice Age is coming and temperature is significant rising.
There is no question that Steam, Carbon Dioxide, Methane, Nitrous Oxide and Halocarbon cause a Greenhouse effect. Ice cores show us that these compounds had a constant value in the atmosphere for min. 800.000 to 20 Million years, maybe much longer. 8.000 years ago (start of farming) this changed slightly. But with the industrial revolution the atmosphere change significant. In 2 hundred years the Carbon Dioxide value has risen about 40%, and the other greenhouse gases have risen comparable.
I don't think it's a good idea to burn over hundred of million year's stored fossil carbon in 300 year's. This must have an effect on the climate.
And it's not only the gases we produce, there is a massive methane production by mass animal husbandry, man burned and chopped forests for farming land and other need. We pollute more and take nature capacitate to compensate it.
Bio Diesel sound good but has worse effect on climate than fossil Diesel. There is not enough cheap useable space for the plants that are needed to make Bio Diesel. So poor countries burn down forests to get mono plant farming land to get money without taken care of nature. And the process of making Bio Diesel out of plants is not very effective by now.
A Question, why do we burn an amazing unlasting resource we are addicted to? Just one example what can be made of oil is plastic. What would life be without plastic?
Do you own a single pair of shoes without plastic in the sole? How many of your clothes are made with plastics? What is the isolator around almost every electric wire or electronic chip? In what is your food packed? Most that is used to seal (or gasketed) like windows or fridges. Nearly everything that is glued i.e. Plywood or Fiberglass. And everything else you could easily see made of plastic if you look at it with full awareness.
