No, it doesn't. It happens because HN shadowbans people who have the wrong opinions. dang and whoever else would say that's not true, but it's tough to debate, because the evidence is conveniently hidden by being unjustly flagged. It's tough to point to a comment and argue that every statement in it is indisputably true, relevant, and polite, when it's been hidden from everyone by some anonymous user without explanat…

Well, I'm glad that the site moderation has no patience for QAnon BS and I hope they keep it this way

Reality is not just "your opinion man" as several people dying with a tube down their throat are figuring out now.

"Global warming" involves extremes of temperature on both ends of the scale, and "coldest winters" are not inconsistent with that. Think about a pot of hot water vs. one that's boiling. The surface of the water in the boiling pot is not smooth, it has peaks and troughs. The level of some of those troughs will be lower than the level of the water in a less energetic pot. The situation with global warming is similar, a…

How is this falsifiable? i.e. how would you prove that a weather extreme is not due to global warming? (general question, not specifically aimed at you).

Wait until there is enough data to see where it fits into trends.

So then a lifetime dictator should have a very green awesome success record? Well, I don't know of any data to support that assumption. Also, most politicians are indeed concerned about their heritage in the history books, so they have motivations to do something beyond their office time. But what should they do? There is not really a broad concensus on how to transform the whole worlds industry into CO2 free. Becaus…

I believe it's an unsolvable problem, too many variables, too many incompatibles interests/goals. Humans aren't made to solve world wide / very long term issues. The covid pandemic showed we're not able to handle any kind of global stress collectively. We're apes trying to live like ants, but we lack the organisation and selflessness. We'll do what we do best, wait until we have our backs against the wall and find so…

That's very deliberate. We've all been saturated with doom propaganda for decades. Many people believe it, despite virtually all metrics of human well-being improving.

It isn't. Climate is a statistics game. You cannot prove or disprove that a specific dice throw ended up 6 because the dice was unfair, but you can still make robust (and thus falsifiable) predictions over hundreds of throws.

We have experienced the coldest winter since 2011 in the Southern Hemisphere (at least South Africa) this year. The summer was also warmer than average. I wonder what less conservative global warming forecasts would look like, and whether the winter this year will be average in US and CA.

That's not at all what "basic physics" says.

For example, in a gas at a given temperature, some molecules are more energetic and some molecules are less energetic. The distribution of energy across molecules is called the Maxwell-Boltzmann distribution and has been known, well, since Maxwell. The Maxwell-Boltzmann formula clearly shows that, if you increase the average energy per molecule, the probability of "cold" molecules goes down, not up as you are suggesting.

I am of course not suggesting that a can of gas is a good model for climate, but I want to point out that basic laws of nature push to the opposite direction than the one you are suggesting. Your wider point may well be true, but if so, it depends on more complicated mechanisms than just basic physics.

While climate change denialists minimize and try to pretend that more analysis is needed before lifting our smallest finger to change the obvious problem (humans burning hundreds of millions of years of sequestered carbon in the span of 150 years) It’s actually rather urgent that we collectively acted like the singular species we are, and acted yesterday already. Don’t wait til 2030 to phase out whatever, let’s go fu…

We've passed stage one and two

"nothing is going to happen" (there's no climate change)

"something may be about to happen, but we should do nothing about it" (the climate change happens anyway, it's not manmade)

Most people are now at stage three

"maybe we should do something about it, but there’s nothing we can do" (even if we stopped our emissions china would be mean)

Some are progressing to stage four

"maybe there was something we could have done, but it’s too late now" (it's too late now, we're screwed)

Do you find it cute to say this complete non sequitur? Is this your way of being civil, thoughtful, and curious?

The EU ‘proposes to raise the EU's ambition on reducing greenhouse gas emissions to at least 55% below 1990 levels by 2030’. At the moment that part of the world is the most ambitious part. > after we move to zero emissions I wonder if that will happen on a planet scale even in your sons lifetime

No because the method of achieving that goal is to push the worst CO2 generating processes out to less privileged countries and then blaming them for it. It's just carbon credits with more xenophobia.

CO2 recycling technologies might make this easier.

> Looking at how we handled the pandemic, I don't think we'll manage. Amidst the chaos, humanity has been able develop a wide range of therapeutics and public healthcare prevention protocols, research and deploy vaccines at global scale in under a year, all while avoiding total economic collapse. What outcome would've given you hope in humans' ability to solve complex and chaotic crises?

The pandemic showed us making and using a silver bullet in record time - when a silver bullet is possible. But the pandemic also showed us a large % of the American population are reluctant to make even minor, temporary sacrifices to protect their country. And that a decent fraction of American political leadership are happy to close their eyes to factual reality.

Protecting your country is a considerably more complex and nuanced goal than “save as many lives as possible no matter what” especially since secondary effects of lockdown also cause deaths.

Long term economic effects for example, and the ability to remain globally competitive economically and in other ways.
