Latest reports indicate it's reducing, might even be over in week or so. Geologists saying it's a start of another 300 year activity period in the area. This is the third in 2 - 3 years, the Icelanders call them perfect tourist eruptions. At the same time, Katla and Askja are showing signs of a coming eruption and those won't be small.

Works for a year or so then it goes back to whatever it was doing before
Did the 1980 Mt St Helens eruption cause any global cooling?
It caused damage to turbine engines in the Nothern hemisphere for a few years afterwards. PT6 hot section inspections had sulphidation of the CT blades for several years.

"While the Mount St. Helens eruption had lowered global average temperatures by roughly 0.1 degrees Celsius, the much smaller amount of ash from El Chichon cooled the globe three to five times as much.
Data from NASA’s Total Ozone Mapping Spectrometer (TOMS), which had been launched in 1978, showed that sulfur aerosols probably were the culprit. TOMS, which measures other atmospheric gases as well as ozone, showed that El Chichon produced 40 times as much sulfur dioxide as Mount St. Helens.
In addition, while a volcano’s ash falls out of the stratosphere within days or at most weeks, the veil of sulfuric acid takes months to precipitate out. It has more time to affect climate."
