Well climate scientists have collected more proof than ever in the last 2 decades to back the models and predictions. What we see is _measured_, not just opinion.
And if you happen to read a bit about how biological systems, the weather systems, our economical systems, food supply et al. work together while keeping in mind that IPCC reports are _conservative_ about their predictions (meaning they rather underestimate than overestimate), you should really deeply be worried about the near-future outcome of the ongoings.
Just because we successfully hacked our nutrition system a 100ys ago does not mean that we'll be able to cope with how consumerism and agricultural intensification afterwards affects us with dozens of new problems. At some point it just gets too expensive and/or too complex for humans to solve.
