Drinking or taking "recreational drugs" allow to momentarily hide problems by reducing the amount of thoughts, but when the relaxed state vanishes, the problems appear more acute and one feels even more miserable.
That comes with a huge YMMV. Lots of people simply do it to have fun, not to escape anything.
The reduction goals in Europe are also going to be hard to achieve. The cap-and-trade system has all but broken down, which has removed all incentive for industry to reduce emissions, and Germany is moving from nukes to coal and gas. The European goals are also only half the story, as a significant contributor to EU reductions is industry moving or leaving - which is in most cases highly likely to lead to a net increase in global emissions.
It also seems I may not have been clear - I'm talking about practical mitigation of the effects of warming, not warming itself. Seawalls, finding new farmland, resizing drainage in cities and such. That's what we should be looking at now. We're in complete agreement on why it's hopeless to spend scarce resources on prevention of warming.
Also, while hope might spring eternal, I honestly don't think a deal will ever become politically possible. Nobody is ever going to come out and tell 5 billion poor people that they'll just have to stop trying to better their lives, for everyone's sake. And no matter how many people die from GW-related effects, precious few will give up their steaks, their plane trips, their 19C house temperatures etc. Any politician who tries to force them to will be voted out ASAP.
