The goal is not to generate hysteria; but to avoid it. Hitting one or more tipping points [1] is orders of magnitude more destructive than prioritising phasing out fossil fuels, and impossible to undo.
But I do understand that some people have reasons not to care about impacts that have an outsized effect on future generations, so to your request: a recent example of a list of impact predictions is the UK Government joint intelligence committee's national security assessment [2].

Many factors influence economics; climate change is one part of the equation. There are many examples of climate change's direct impact so far - floods, fires, sea-level rise (requiring investment in massive public works), droughts, etc. I don't think it's debatable that these things have negative economic impact.
Climate change is expected to greatly increase its impact in many ways. Let's not wait until it overcomes all other factors in economic growth and makes our economies shrink.
The planet went through much worse climate change cycles

And remember, climate change is not something that happens and then it is done. What we are seeing now is just a start of much worse to come.
Associating action to prevent with 'de-growth' is disinformation from the deniers. Climate change itself is massively de-growth. The question is how to best prevent it.
