Due to the volcano in Iceland spewing smoke nonstop, it has spread all across Europe. This caused many flights to be grounded and train stations packed. There will be more pollution and dirty air over there too.
How long will the volcano keep pouring in smoke and how long will the smoke over in Europe linger?
If it decides not to stop for another couple years, you're looking at global famine. >.>
I think when he says global famine, he means world wide food shortage. It should be global dimming where the earth gets cooler. Jet streams are a source of global dimming.
Is that when the Ozone Layer blocks out the sun in some Areas? Explain.
Ash reflects the sun very effectively. Last time we had a big burner that lasted that long of spewed out as much was Krakatoa, and that made global temperatures drop enough to notice, and a lot of crops didn't grow. Didn't last very long, only a few years, but was a major pain in the neck.
