Firstly: climate change is only one of the problems caused by a culture based almost entirely on the ecocidal fantasy of stolen-from-the-future 'economic growth'. We are losing topsoil at a dizzying pace. Fresh water is disappearing. The habitats on which natural systems depend are being ripped apart. Novel substances are being created and released into our air, water and land with unknown consequences. Climate change is a single crisis piled upon multiple others. Case in point: Australia's Queensland inner reefs are almost completely gone, and the outer reefs have only a few decades left. Causes: multiple, from nutrient-rich agricultural runoff (largely from pointless vanity sugar cane production), to wholesale destruction of coastal ecosystems including mangroves, which are crucial nurseries for many reef fish. Increasing ocean temperatures deal the final blow to already critically weakened ecosystems. This is our planet in miniature. Climate change isn't the problem. It's yet another symptom of the same fundamental dynamic, delivered as just the latest and largest of a series of blows many ecosystems will not survive.
Secondly: the changes needed are not only (and perhaps not primarily) technological. They require planetary coordination and cooperation to handle on political and social levels, and the defeat of a crazed unthinking ideology of unhindered 'economic growth'. Fundamental changes of attitude and societal organisation need to be agreed upon in the next few decades, and implemented without delay. Yet we can't even agree on obvious tiny measures like removing nuclear weapons, and rogue wealthy nations resist nearly every attempt to do anything meaningful about any of the critical issues. We just don't know how to do what's needed, and there are no solutions on the horizon. And we are still locked into fantasies of national government and sovereignty, despite being (factually & physically) a global civilisation.
Look at the political convulsions happening now as a consequence of current worldwide refugee crises. But that's minuscule compared to what's coming. Imagine what happens when ocean level rises cause two billion refugees to seek somewhere to live. Given our level of global immaturity, what do you think will happen? It will be all wars and walls. And our capability, in the midst of such convulsions, to make (and keep) difficult international agreements? Nil.
I'd absolutely love to be wrong. But all physical and social indicators are pointing in the same direction.
I suspect that crispinb deems something much more paradigmatic necessary than just a bit of reprorization in economic policies and everybody using less plastic bags. Some paradigm shifts are so big that it is very difficult to even think about them loudly without getting universally shunned.
What if, for example, you are convinced that for long term planetary survival (on a level that can support the human species), individualistic basic human rights will have to occasionally take a second place? That's what tyranny is made of, but that's also what desperate measures are made of. You won't win any popularity contests with that...
> individualistic basic human rights will have to occasionally take a second place?
One could argue that this is the case right now. That the lack of protection of individual human rights is what got us into this mess. It wasn't individuals in communities that asked for their lands to be taken by a wealthy few or by corporations, to be used for generating profit through environmental destruction. Many people actively struggled against the acquisition and destruction of local ecological habitats. They were a majority opposing a small few powerful people or businesses. But the "individual rights" of those few were valued more and now the many must suffer the consequences...
Oh, hey, thats about the same "phenomenally short time span" that everything started going to shit.
Too late for that. And I don't see anyone offering easy answers.
But pretending that what's happening in the real world isn't happening, or frantically waving totems of electronic consumer satisfaction about, won't make those physical realities go away.
But everyone wants to live on an island of asphalt with a sterile, depression patch of grass in front, at least three miles away from the nearest place to buy a cup of coffee (a disposable cup, natch).
Actually, not everyone does, but those who do, made it illegal to build anything else. At least in the US.
... I love how the cliche environmentalists worldview is to reduce these problems to entirely the result personal choice. As if consumers chose petroleum as the most efficient and widespread fuel in the earth's crust, and the combustion engine, then decided they wanted highways and suburbs, etc. Instead of thousands of small choices over a century (or more) based on circumstance, central planning, present needs, etc - things largely out of their control. Combined with other biological human flaws like short term thinking and favouring political populism and emotion when voting/buying.
Not to mention, the widespread adoption of suburbs was not a product of market capitalism or consumerism... it was the result of government zoning and regulatory policy:

You may be convinced and have deep knowledge of the subject but it's far from common knowledge. Understanding of climate issues is very low and it's not entirely the result of ignorance or malice or compromise because someone loves having a big lawn.
I tried to educate myself on the subject, I love to read, but even I found it difficult to find good books on the subject, specifically books that were balanced and scientific instead of sounding like the ravings of an ideologue.
I've asked on HN for book recommendations on climate change multiple times and each time I've been pointed to websites with dry 150 page reports by non-profit organizations. It's far from easy to know better.
Things like electricity, the automobile, air travel and the internet went from nonexistent to universal in developed countries in phenomenally short time spans. Renewable energy appears to be following a similar trajectory, leaving all the estimates in the dust and emerging faster than most people realize or can keep track of. Fast enough? Well, we'll find out. But at this point you can't say it's slow.
