I don't see why climate change needs "solving" per se, or how it can be "solved." To take your example, there have always been hurricanes. It's not correct to infer there's a human-induced tendency toward destruction that can be reversed by humans, or that yet another hurricane is actually a change to the climate in the first place.
It isn’t correct to infer that from the fact that hurricanes exist, no.
Nor is it correct to ignore the decades of peer-reviewed research that concludes that we really are causing more hurricanes on the basis that hurricanes have always existed.
Marriage goes way beyond the Jewish and Christian spheres. It's a far-reaching anthropological value. Strictly speaking it's a natural state, which means it isn't an invention. What we're missing most of all in contemporary times is an appreciation and acceptance of our contingency as beings. For want of this restful appreciation of what we really are, we have a tendency to become angst-ridden, semi-nihilistic types trying to find our bearings through acts of will and experiencing misery because we can never get there from here by traveling that path.
Grand ideas about structuring society often have an egotism problem. The ego behind the ideas turns its critical lens outward without looking inward. Naturally it ends up telling the world what to do.
When postmodernists describe language as referential and arbitrary, they are moving headlong toward nihilism when an "uh oh" borne of caution and self-awareness is in order. Language comes from the human need to communicate, which need none of us can erase; and to be aware of this is a step toward proper humility in the face of our contingency as beings. "Melancholy" and disaffection are likely outcomes if instead you cling too hard to egotism and insist on seeing yourself as a utopian reshaper of entire worlds.
“... that you are nothing more than a lucky species of ape that is trying to understand the complexities of creation via a language that evolved in order to tell one another where the ripe fruit was.”
and as Terry Pratchett might have written but probably didn't, he himself is an ape convinced that the complexities of creation are necessarily more than telling a friend where the ripe fruit is, without much evidence.
But that is refutable. You're not a true nihilist as long as you take advantage of the accoutrements of civilization, even down to the technology that enables you to make that post. You can avoid taking advantage of such technology in the spirit of "starting over" (even Pol Pot tried that) -- or you can say the technology around you admits of some advantages, which means limiting the nihilism/radicalism enough to pay credit to something around you. (To borrow from the postmodernists: "Not that there's anything wrong with that.") But for a nihilist that would be an unlikely reversal: the ego having stomped everything under its foot, is now making room for something outside of itself.
[As to technologies I habitually use, they serve roughly as I choose them to serve — sometimes more or less. (but always under my intention of contributing to, rather than providing meaning for, my life) The question is, which is to be master — that’s all]
There isn't much to "colonialism". It's just the establishment of colonies. In the many historical cases where the subject peoples were cannibals, I would have supported colonization.
"Fascist" began as a neutral description of political-financial relationships and was later made into a household slur by the Soviets to take the heat off after people started likening them to Nazis thanks to their short-lived military alliance, their shared "-ism word", and their common interest in techniques of political oppression (search term: "Gestapo–NKVD conferences"). In this context, there is no logical connection to philanthropy much less to "white supremacy", a term that's almost always used monomaniacally.
Nowadays there are places in the U.S. where the tech staff are largely from (what used to be?) the 3rd World, and it definitely has its effects on the workplace culture. There are teams who rationalize being spoken to like they're garbage, and who cannot be persuaded to push back. If you don't choose wisely, you could find yourself stepping into a self-contained Calcutta every time you enter the office building.
