1. Yes, but due of not fully understood behaviours some regions get temporaly colder. 2. Yes and yes. Humans invade regions with wild animals that have yet unknown diseases, the regional climate changes(regions where rainforest was burned of now are on the verge to drying out). 3. The land where the 9 billion people can eat and drink from the land they are living on gets smaller, so people fight over it or flee to escape this to regions where it is still relativly safe. That includes the region you are currently living at. I don't have much information about you to fully answer it, so you have to think what you do with the information. 4. Yes, if you look at ice that is thousands of years old, you can calculate the amount of co² in the air. And that has been emitted since roughly at the start of the industrilization of humanity. The mean temperature has been risen since then. 5. Co² emission is the biggest factor we can influence. Once its in the air it stays a long time. 6. In the long term: yes, in short term: no.
