Is this all caused by us humans? I'm totally against pollution caused by us, but for global warming, who is the major source contributing to it, could it be beyond us, e.g. the solar system cycles etc. We had ice age/geenhouse eras in the past without human's existence at all?

List of Icehouse and Greenhouse Periods
A greenhouse period ran from 4.6 to 2.4 billion years ago.
Huronian Glaciation – an icehouse period that ran from 2.4 billion years ago to 2.1 billion years ago
A greenhouse period ran from 2.1 billion to 720 million years ago.
Cryogenian – an icehouse period that ran from 720 to 635 million years ago, at times the entire Earth was frozen over
A greenhouse period ran from 635 million years ago to 450 million years ago.
Andean-Saharan glaciation – an icehouse period that ran from 450 to 420 million years ago
A greenhouse period ran from 420 million years ago to 360 million years ago.
Late Paleozoic Ice Age – an icehouse period that ran from 360 to 260 million years ago
A greenhouse period ran from 260 million years ago to 33.9 million years ago
Late Cenozoic Ice Age – the current icehouse period which began 33.9 million years ago
- ausjke 7y agofor the down votes please educate me, I'm not on either side, I just want to know more.
- adrianN 7y agoYes, it is all caused by us. The cycles you speak of would currently put is into a cooling phase. Check out this article: https://en.wikipedia.org/wiki/Attribution_of_recent_climate_change https://en.wikipedia.org/wiki/Attribution_of_recent_climate_...
- ausjke 7y agoif that's true, maybe we should just heating up the earth while it's going to be frozen, so we're actually doing our future generations a favor?
- adrianN 7y agoWe're overdoing it a bit. We should have stopped about ten to twenty years ago. Already today it's warmer than it has ever been while humans were around.
- ausjke 7y agoif we did not do it, could the earth be having a much cold climate then? I really want to have a balanced view on this climate topic, but either side is too extreme about supporting their one-sided points, just like the news medias. science should be totally based on facts, but what I saw is that, some studies are sponsored by big industries, some are supported by political parties, some individual opinions are threatened, how chaotic.
