claim: Volcanoes have been relatively frequent and if anything, have exerted a cooling effect.

evidences.evidence: Large eruptions can affect temperature as ash and droplets of sulfuric acid obscure the sun and cool the Earth's lower atmosphere (or troposphere); however, they also absorb heat radiated from the Earth, thereby warming the upper atmosphere (or stratosphere).

evidences.evidence: The aerosols increase the Earth's albedo—its reflection of radiation from the Sun back into space—and thus cool the Earth's lower atmosphere or troposphere; however, they also absorb heat radiated up from the Earth, thereby warming the stratosphere.

evidences.evidence: This magma tends to be extremely viscous because of its high silica content, so it often does not attain the surface but cools and solidifies at depth.

evidences.article: Volcano
evidences.evidence: Such volcanoes are able to severely cool global temperatures for many years after the eruption due to the huge volumes of sulfur and ash released into the atmosphere.
