There is no reason to think they will be met, on current trends -- global output is still increasing, and new "green" energy seems to just come on top of fossil fuel energy, not replacing it. But it makes no sense to spend money on the effects while the rate at which they're getting worse is still increasing. Like starting to repaint the house while the fire is still blazing. We just need to do a lot more, keeping fossil fuel in the ground forever will always be more effective than any measures to live with the consequences.
