My undestanding of evolution makes me think 1 generation to the next there would be no obvious changes. I believe evolution takes place over thousands of years. People leaving Africa and moved into Scandinavia and Northern Europe grew noses that were longer so people with longer narrow noses could survive the cold more efficiently than people with wider nostrils that needed wider nostrils to cool their bodies.

Human evolution doesn't take place in one generation ever. There was a VERY gradual transformation caused by environmental conditions that increased our brain power, changed our bodies, etc. over MANY generations, by passing down favourable traits/aspects from one generation to the next.
If human evolution is continuing, in the more general sense, I would say undoubtedly. In what direction though, nobody really knows. I would imagine that our brain capacity will continue to increase (though this could cause problems, as we are already at the limit of the female pelvis for giving birth!). Other physical changes will be diminished, as we now control our environment, but we really don't know if they will stop completely.
Without knowing what our future environment will be, and if/how we would need to adapt to it, it is impossible to know the form we may take. There would be no noticable changes for tens of thousands of years though.
Unless we start to tamper with the human gene, of course. Then anything will be feasible.

Evolution does not happen within one generation. It has to be a series of generations, that's part of what defines evolution.
Further proof (from Wikipedia):
"In biology, evolution is change in the heritable traits of a population over successive generations"

Not necessarily in this particular generation, but evolved in the generic sense of "changing over time," yes; but not in any way connected with the scientific theory of evolution.

I can tell you yes. I am a doctor and have noticed in my readings and in thirty years of practice that more and more babies are born without finger and toenails, shorter fifth fingers and toes, and many more children are born without fifth fingers and toes than say 50 years ago. Put it down to evolution.

Yes.
In this generation, women with careers have fewer children than those who don't. If there're genes for women having careers, then in the upcoming generation, its allele frequency will be decreased, and you'd expect to find girls growing up not interested in having careers.

Yes, but the changes are subtle, and the selective pressures shifting.
