There's a feedback loop to increasing greenhouse gases and increasing temperature.
For example trees being burned (at a faster rate than they would die naturally and regrow) resulting in less trees to bind CO2.
The opposite is also true: Algae in oceans grow when temperatures rise, binding CO2.
I think the fact that we don't look at our solar system as a whole instead of trying to isolate data to "prove we are doing this" is indicative of politics corrupting science. We need to get back to pure science and forget about trying to force this country or that country to do something, namely force it's citizens to pay a tax that fixes nothing.

"Many scientists suspect that the solar system has migrated to a region of the galaxy with high energy."
Can't tell if satire or hippies.
It could be science.
The solar system is moving at 230 km/s after all. [1]
It's not the movement that triggers that, but rather the "with high energy" part. It makes no sense in context, and the hippies I know love to use "energy" in nonsensical ways.
