You can google actual studies, but those are the primary points behind reasoning that climate change is happening because of humans.

The last link is why that should be something to worry about. The planet has in fact been much warmer and had much higher greenhouse gas levels in the distant past, and it's been fine and in a stable equilibrium. The worry is that the only previous occasions of change this rapid were extremely large natural disasters which occurred near mass extinction events. The theory is that most life can't evolve fast enough to cope.

We'll probably be fine as a species because we have technology to help keep us alive, but the ecosystem as a whole is likely going to be unrecognisable. Half the fish are already gone, most of the coral is dead, and a hundred species go extinct every day.

Temperature changes caused by large, rapid emissions of greenhouse gasses have happened in the past (such as from massive volcanoes). This graph shows mass extinction events by how close in time they occurred.
