Global temperature change is a natural process that takes place over millennia. It's caused by changes in the sun's radiation output, the earth's orbit (changing from circular to ovoid and back), the earth's axial tilt and wobble, etc. Mankind has diddly-squat to do with global warming.
If a full-on nuclear war wouldn't cause nuclear winter like we thought it would in the Cold War, how the heck would American industry cause the entire planet to get warm and doom the earth? Charcoal and wood cooking fires in China put out more CO2 pollution than all of American industry combined, and I'm pretty sure the Chinese (and everybody else) have been cooking that way for a lot longer than the so-called 'global warming' has been going on.
In any case, if the earth really DID warm to the point that the polar ice caps melted significantly, it would cause ANOTHER ICE AGE. The Atlantic undersea current brings warm water from the south and deposits it between Europe and North America, then sinks with the cold water and brings it down south between South America and Africa. Thus, the Atlantic is circulated and keeps roughly the same temperature. If the ice caps melt, however, enough fresh water will eventually be introduced to the ocean that it cannot achieve the same density when cold. The conveyor belt will break down. Cold northern water will sit in place, cold southern water will sit in place, and warm equatorial water will sit in place. Eventually, the earth would get colder thanks to the break-down in temperature exchange and we'll have another short-term ice age like the Little Ice Age from 1300 to 1860. It's even more likely if volcanic activity increases.
Volcanoes can cause global cooling by introducing sulphuric dioxide into the atmosphere, raising the albedo and reflecting more sunlight, reducing the solar radiation absorbed by the earth. This is believed to have caused the Little Ice Age (and later the infamous Year Without A Summer) in conjunction with a temporary break down in the Atlantic currents from the medieval warm period.
Ironically, coal plants produce sulphuric dioxide (of course, even if we converted 100% to coal power, we still can't produce as much as a single volcano, much less a super volcano) and could lead to marginal global warming, but the cult of global warming is 100% against burning coal. |
You mean ash dont you. If you didnt mean ash, then you should have. Ash "blocks" out the electromagnetic radiation and causes cooling. Oh, and humans put WAYYYY more greenhouse gasses into the atmosphere then volcanoes.

No, I mean fucking sulphuric dioxide. Ash is ash.
Which shows you know about as much about volcanoes, greenhouse gasses, and pollution as the average third-grader.

See my link above. Go ahead and prove me wrong. Ill be waiting............ |
No, he is correct. Ash is rapidly setteled in the lower atmosphere. SOx, usually in the form of SO3, remains aloft much longer, contributing to greatest long term shading. This was very eivdent in the post-Pinatubo sunsets which persisted for over a year. You see, ash cannot maintain bouyancy at high altitudes and it rapidly gets washed-out in the troposphere.
