| Description | Sulfur dioxide emitted from volcanoes and from burning fossil fuel is the primary initiator of global climate change, according to Dr. Peter L. Ward, a retired U.S. Geological Survey scientist who continues to study the earth and its environment through his own company, Teton Tectonics. "Carbon dioxide is a greenhouse gas compounding global warming, but it is not the initiator of climate change," according to Ward.
In a paper to be published this week, Ward concludes that sulfur dioxide emissions regulate the ability of the atmosphere to clean itself by oxidizing greenhouse gases. Sulfur dioxide reacts quickly with available oxidants, leaving few to react with other greenhouse gases. The primary oxidants, created by the effects of ultraviolet sunlight on ozone, are, like ozone, in limited supply.
Ward observed that the highest rates of global warming in the past 46,000 years occurred precisely when volcanoes were most active. "When very large volcanic eruptions occur every few months," Ward says, "rapid warming follows. Too much sulfur dioxide in a short period of time causes warming."
Large eruptions in the past 2000 years occurred once per century. Yet by 1962, human activities were putting as much sulfur dioxide into the atmosphere every 1.7 years as one of these large eruptions. That was enough to cause world temperatures to climb rapidly.
Beginning in 1979, global efforts to reduce acid rain cut power-plant sulfur emissions 18% by 2000. By 2000, global temperature stopped increasing, a fact unexplained by current climate theories.
