Volcanoes actually have an opposite effect, and reduce temperatures through a process called "global dimming". Simply put a large increase of particles in the atmosphere will reflect more solar radiation and cool the earth. This was demonstrated dramatically in 1816, the year after a massive volcano had erupted in Indonesia. Known as the year with no summer, the east coast was especially hard hit. Snow up to a foot was still reported in Quebec City in mid-June. Ice was still seen in lakes and rivers as far south as Pennsylvania in August. a month when light snowfall was still being reported.burlboy said:
Scientists have suspected for years that even the ice vapor contrails formed by jets might have an effect. During the three days that air traffic was grounded after 9/11, they had a unique opportunity to observe any change. What they found was that daytime temperatures rose uniformally across North America, and then decreased by the same amount once jet flight resumed. The earth has a very delicate balance in how much solar radiation is trapped and how much is reflected, which is why the melting of the ice caps is so troubling. The North and South poles serve as air conditioners for the earth, not simply because they are cold, but because the high reflectivity of snow and ice bounce much of the solar radiation that strikes back into space. As the poles continue to shrink, the process accelerates, since there is less and less surface area to reflect the sunlight. The poles continue to melt at a faster rate than scientists predicted even a few years ago.
