That's because it's supposed to be a doom article. Nobody has any idea, it's not something you can quantify (well you can, but if 99 of the 100 simulations say nothing and 1 says we all die, what does that mean?). And when it does happen it will largely be too late to do anything. Which is why we get doom articles like this. It's purpose is to attempt to get people to care. The earth could just fix itself. It is very capable of doing so, and has done so in the past. It may not be able to sustain us anymore, but life will live on in some form.
