A major weather modifier, erupting volcanoes. I've lived here for over 50 years and can't remember a spring as cold as this one, and like me, you have probably been asking, "why?" If "global warming" is to be believed – which seems irrefutable – why isn't this phenomenon warming up Central Oregon? The reason may be what is happening in other places, such as erupting volcanoes.
In the not too distance past, exploding volcanoes had considerable impact on what happens to the weather throughout the Northern Hemisphere.
Take the year 1816 for example. In New England, it was known as "The Year There Was No Summer," the "Poverty Year" and "Eighteen Hundred and Froze to Death." Moreover, it wasn't just New England, the entire Northern Hemisphere suffered. In Ireland people starved to death because potato crops failed, while the resulting famine caused cholera to spread across northern Europe bringing widespread death and horror.
