We're gonna die?

I'm not smart, I'm easily anxious about Climate Change in large part because I don't understand all the ins and outs, some say we've avoided catastrophe, others say a climatic cataclysm will happen in 2030, others say there's hope, others say we're not doing enough, not to mention the tons of percentages and graphs and other stuff with mathematical tricks and all...

So overall and without going into doomerism/cynicism, just tell me where we stand, simple, concise and all, because I don't think I'm the only one who's totally lost.
