Richard, a noteworthy PAUSE in the rising trend of global temperature was obvious for a few years after Mt St Helens erupted in 1980 and Mt Pinatubo in 1991. Although megatons of greenhouse gasses were released during those years, megatons of ash and dust were also released, causing significant reflection of solar radiation away from the earth. CO2 levels have been rising without pause, which shows that CO2 levels are not as significant as climatologists claim. Man-made changes in land use contribute most to global temperature rise.
