Can climate change be caused by earths position and volcanic activity?

Answer 1

YES, earth's position and volcanic activity does affect climate change but out of the whole causes, air pollution is the main culprit, volcanoes spew out CO2 when they erupt along with other greenhouse gases such as sulfuric dioxide and monoxide, methane and others, these greenhouse gases trap the heat from the earth's interior and from the sun thus increasing earth's temperature or a sudden change in climate earth's position also affects climate when the earth is farther from it's normal aphelion a sudden drop in temperature occurs and during nearer from it's normal perihelion, a sudden increase in climatic temperature on earth such as the other planets like Mercury and Venus which have higher surface temperature than earth's since they are near the sun and the planets far from the sun has a lower temperature than earth's, this shows that a planet's position from it's parent star affects it's climate
