understanding of how volcanoes react with the atmosphere in the climate in the short term is through the injection of sulphur dioxide into the stratosphere and creates a kind of cloud and creates a kind of cladding that reflects salary variation on that because the planet down a bit. a global cooling of about half a degree over a couple of years has been the biggest eruption of that kind in the last 40 years. the magnitude of gas from this one appears to be at least ten times less, so the main many messages that the current cooling we can expect from even the biggest the next 100 years or so were not going to be significant enough to counteract the warming trend we have going. counteract the warming trend we have anoin. ~ . counteract the warming trend we have ttoinr ., ., going. what about the impact on humans? it going. what about the impact on humans? it must going. what about the impact on humans? it must be going. what about the impact on humans? it must be awful- going. wha
