If you think society can adapt and a reasonable reduction of CO2 over time is the best approach using market forces, then for example, degrowth sounds like a bad solution. If you think we're doomed in the next decade, then might as well start geoengineering.
Then for example you might be a flat earther too. We've been trying that for past two decades and it's an epic failure.
Arguments about what to do about it, or if it is a 'big deal', are subjective ones- so there is no right or wrong in most cases.
1. This is worthless nonsense.
2. This is an interesting, but perverse, point of view.
3. This is true, but quite unimportant.
4. I always said so.
Stages 1 and 2 are approximately denial, stage 3 is the skepticism you mentioned
My issue with climate science, apart from it being more ideological than science when I studied it in college, is that we only ever talk about the last 100 or so years when we know so much more about Earth climate history from geological studies and their impact on prehistoric humans (paleoanthropology). Yet that history is left out. For example, we know that CO2 has been MUCH higher in the past due to increased volcanic activity.
You can both hold the idea that climate change is happening but it's also not going to completely doom the human race to being wiped off the planet. Extreme fear-mongering by climate sensationalists is every bit as bad as "denialism". In fact it's worse, because you make people believe they're helpless while simultaneously creating a group that reacts violently due to the fact they've been conditioned through fear.
Ok, how?
Or, to put it simply: in this case, it's the doomers that need to answer how and why.
Things are improving, humans will adapt etc.
You were far more likely to die from a number of natural things before modern inventions (yes the ones that are now causing climate change) helped keep you well fed, warm, etc.
