This is blatant anti-science.
That is absolutely not anti-science. There are climate deniers and climate truthers that only regurgitate the bullshit of the political ideological spectrum they espouse where the reality is actually somewhere between. Thinking Climate Science is "settled science" is an absurd saying. Science is never "settled". Science is the act of questioning everything, and then figuring out new questions to ask and then questioning their previous conclusions again. Scientific Method is a philosophy and there is a term that describes when any majority consensus ends up being wrong and changes. This happens often enough they even have a term for it, a "Paradigm Shift".
Lets forget "climate change" completely for a moment and focus on astrophysics. This planet is not some lone body unaffected by anything except for it's local environment. It's one tiny participant that is linked to the very whole of the universe itself. The Earth is affected by solar magnetic fields, solar radiation, solar wind, solar dust, solar plasma. You've hear of Aurora Borealis? That has everything to do with the interactions of our magnetic field and bombardment by our star and during mass coronal ejections or superflares, that's been visible far south of where they usually reside.
Our planet is interconnected with our star and all the other planets in the solar sheet, and we're linked to our local star systems as well as to the galactic sheet. Our galaxy is interconnected to the galaxies that orbit ours and to our local group along to the universe. The cosmic microwave radiation and the intergalactic filaments connect everything. You can go search for the latest recent studies and images actually showing solar and galactic electromagnetic influence and connections. That is actual science.
Yes, humans are responsible for trashing and littering our own planet... you cannot live in an area and cause destruction and waste without having to face the consequences. Trying littering shitting and pissing in your room never cleaning it. How does that look like after a week, or a month, or for years? Or your yard. Or everyone in their towns. Or all of humanity in the world? Of course we're altering things to ways they wouldn't have been if we didn't exist.
But to call modern astrophysics science denial? We still don't even know why reality exists or how it works. We're still a primitive species not far removed from living in caves fearing the darkness. We're still trying to figure out basic things like gravity and consciousness.
I won't even go deep into what our star can actually do to our planet on it's worst days, but there have been major extinction events tied to weakening magnetic fields, like how we're experiencing right now. One superflare could knock out all of our electronics and technology and put us back into the dark ages for decades. A local supernova could gamma ray burst burn us all to death immediately. The planets could align in a specific way to pull a trans neptunian object out of the Oort cloud and directly impact us. An extreme volcanic event could easily turn this planet into an ice world.
Geomagnetic storms can even alter human behavior, knock out the power grids, or perhaps even kill sattellites. If you accept science, you should know what we do here as humans affecting our environment is only one small part of a huge picture billions of years old. It is pure human ego to think that only what we're doing here is the only thing that matters when nobody can really do anything to prevent the progress in industrialization. You can virtue signal while sorting your recyclables and scream "science denier" as much as you want but you're just as much a part of the problem as one you would chastise.
