The Pinatubo eruption was more significant. Some day, there will come a time when all the particulates from human burning settle out. After the population crashes and oil is mostly depleted, the remainder of the coal stays in the ground, and no volcanic eruption to mask AGW>methane self release>to 10x more rapid and greater than PETM warming. Right now, India's soot cloud is 7 times larger than the country, decreases the Maldive's crops 10% and settles out in the Arctic on ice, making it melt faster. Some places downwind of US coal plants get a 20% yield reduction and one area I read about caused an 80% reduction in pecan yields!!! Not far from you, Wayne. The Chinese cloud is full of toxins that settle in the streets of Seattle, and some of the mercury goes much further--even to making pristine Rocky Mountain lakes' rainbow trout only safe to eat two per week. The Pacific fish are much worse, to the point of authorities not testing enough, but NGOs report that more than one serving per week is unsafe. It is in the runoff that goes into the Mississippi's Lake Erie sized dead zone. The no fly days after 9-11 and the 2-3*F temperature jump, because contrails masked AGW. CO2 exhaust has increased 3% per year since then, with soots masking much of AGW, along with the contrails. Some of the soots the perfect size to start cancers. Personally, I think AGW at mid northern latitudes is +7*F(often). We know it is over +10*F above the arctic circle, and +1*F in the tropics and +3*F in Antarctica. So AGW is well beyond historic and is making new records in temperatures and weather effects. Even with the dimming and contrails that often mask most of it.
