Because the luminosity of star declines exponentially with star mass, the Goldilocks zone around a dwarve star would be in a much steeper part of the parent star's gravity well than the earth is on the sun's. So any planet in proxima centauri's Goldilocks zone won't be earth like: It is probably tidal locked to its parent star. One side is perpetually day, the other perpetually night.
Furthermore, dwarve Stars seem to exhibit much higher level of flare activity compare to its luminosity than a sun like star. So any planet in proxima centauri's Goldilocks Zone would likely be much more swept by solar flares, may be stripped of any primordial atmosphere, than the earth.
