There are a lot of factors at work here at the same time.
It's far off (or perceived that way) and people naturally seek relief of immediate pain. It's human nature. You tell somebody that they'll save $X over the next 10 years by spending a fraction of it now, most won't bother. On the other hand, if you're currently spending $X on something and you need to invest in something to get that cost down, they'll do it almost immediately.
Because it's far off, there's not a sense of urgency to it.
Additionally, there are some fairly strong factors that call a lot of climate change activism into question, like wide spread opposition to nuclear power by many of the same activists. Examples like Germany shuttering nuclear facilities only to turn around and turn to coal power certainly doesn't help.
Other factors such as the need for change across the entire world complicate matters when numerous businesses will just send their pollution to countries that don't impose the same requirements.
Separating hyperbole from practical application in pursuit of pre-existing goals is another huge factor. We've heard about methane emissions from cattle ranches for years. It seems like we have a great solution for this by adding an ingredient to the feed:

But rather than pursuing this, activists are more interested in continuing to attack the industry and pushing vegan diets when a potential solution seems readily available.
Factor that in with alarmism over temperature increases as if every potential increase is man made while other factors are ignored by most outlets...

There's just a great deal of inconsistency and alarmism that undermines credibility when ignored.
