I really don't see europe failing before 2050, and that was the time horizon i mentioned...
Europe will be short on energy most probably around 2025 (all of its oil and gas suppliers are already in decline). That could be pretty bad by itself. Also, +1.5°C is generally anticipated for 2030, and it could be really bad, too. Both together: huge pain is almost a given.
