Yes, biologically speaking, most hings were perfect 100 years ago. Because most of the planet was in an equilibrium. Any rapid change from that is making things worse for some time. We are changing the climate faster than the system can adapt to. This doesn't exclude that some things might get better long term, but short term (a century or more), it is mostly bad.
