Planetary temperature fluctuations aren't a crippling problem if they take thousands of years to manifest, but what we see happening now is way, way too fast for most species, including our own, to adapt to. Biologists estimate a loss of 30% of species by 2050. Mass extinctions have happened many times in the past. They also are not a crippling problem, except to the species that go extinct, or to the species that depend on them. Of course we do depend on a great many species, e.g. to eat, to pollinate crops, and to build houses from. Even in the worst case, humanity probably won't go extinct, but a 90% (or 99%) population reduction would be hard, particularly on those most dependent on the rest; e.g. you and me.
It's nice to pretend the Earth is too big for people to affect, but the facts are that (1) the CO2 level is much higher than a century ago, and (2) we are clearly the source, and (3) big changes obviously affect the climate.
