We're definitely going to go beyond 2ºC in the coming decades.
Even if a miracle happened and we stopped all human emissions today, current GHGs in the atmosphere will keep trapping more heat for some decades. This is known as climate inertia or climate lag.
Another aspect I don't see frequently mentioned are feedbacks. Again, even if we stopped all emissions today, self sustaining climatic systems will keep adding more heat to the atmosphere (methane, etc) or the sea (Arctic ice melting).
We're currently at aprox 36 billion tonnes of carbon emissions per year [1] only counting fuel burning. It would be a miracle if we could even reach 50% of that in our lifetime, which was aprox the emissions from the 70s.
