I doubt this is going to be that 'year without a summer', though.
We will see. Tambora was obviously worse, so no not similar. But it might have an impact on the climate but it's too early to determine to what extent (and even than, it might be regional, or locally and what kind of effects might be unknown, and it would be only temporary as well).

England was reached, parts of Europe too. Directly antipodal to the volcano is Algeria where the pressure waves will converge, and they would have travelled around the world by than once.
That's interesting. What would be observed in Algeria when the pressure waves converge?
