I have a hypothetical question. If there was a relatively Earth-like planet out there that somehow experienced a rather catastrophic meteor impact large enough to alter its axial tilt close to 0 degrees, would such an event render the planet essentially a desert world? I.e. there are no more seasons, no more poles, oceans essentially dried up (or would they be dried up?) Obviously the way the question is worded betrays my ignorance, so forgive me. Thanks for your time.
