I prefer the direction independent term "Global Climate Change". That the climate is changing is unarguable. Let's say humans had no impact but the Earth was going to get 15 degC hotter anyway. Should we / would we do anything?

Man has been modifying the climate by redirecting water flows, digging wells, seeding crops, etc. for 20,000 years. Why stop now? But we would be idiots to ignore the warnings of increased ocean depth, storm intensity, algal blooms, and desertification.

The most important piece of information I can provide to people is that the poles of Mars are melting and a number of other planets are experiencing warming. There are a number of indications that what is happening on Earth may be part of a bigger set of changes such as proton flux or some other factor.

Since there are no SUVs on Mars, we may simply be moving from a less dense part of the galaxy to a more dense part of the galaxy. We would be foolish if we chose to do nothing because "it isn't our fault". If one's house is falling down because there is an earthquake, it doesn't matter that the house was "built properly" or that the "contractor is not to blame". As a bunch of people on raft in space, we should always be looking to keep homeostasis going on our sweet little rock. If we are experiencing friction from our interaction with interstellar proton flux we are just as screwed as if it is from burning fossil fuels. Reducing CO2 levels is a good deterrent to further heating.
