re: #402 6pat6

Actually you are correct. Continuously erupting volcanoes emit huge amounts of green house gases. Huge. (Kilauea) But huge explosive eruptions send particulates high into the atmosphere (Pinatubo), and when they reach 50,000 feet or so, the silica ‘floats’ and its reflective nature causes cooling. There are also cloud effects that are not understood. But the net is cold for explosive eruptions, hot for persistent low level ‘lava flows’.
