I'm saying that we don't need to know what those numbers are to know there's a problem.

You're asking leading questions which contain a lot of presuppositions, and you're ignoring my post in which I specifically reject those presuppositions, which makes it hard for me to believe that you're just trying to learn.

One metric which indicates "definitely super broken" is if the wet bulb temperature[1] get's to the mid to high 30's. Any regions where that happens for sustained periods is uninhabitable for mammals (which we are a subset of)

Before a region get's there consistently, it'll be that way intermittently and many people who can leave probably will because even in the high 20's and low 30's it'll significantly impact humans ability to do things.

Awesome! Thanks!

Let’s assume that’s the number.

What I, as an individual, can do to help?

This serves for all the other commenters complaining about my responses.

If you can’t provide something that I can do as an individual I can’t help you.

It doesn’t matter how much we complain about how governments are not doing what they are supposed to if we can’t start with the smallest organizational unit of our planet which is the individual.

1. Involve yourself in pro-environmental politics, vote for pro-environmental leaders and policies. Most personal environmental decisions are dwarfed by the poor decisions made by large, corporations.

2. Consume less.

3. When you must consume, buy used (much of the carbon footprint of many products comes from producing the item).

4. Buy more local goods (much of the carbon footprint of many products comes from transporting them long distances).

5. Travel less, and more carbon-efficiently. Live closer to where you work. Walk > bike > public transit > cars.

6. Stop arguing that climate change doesn't exist.

7. Spend a few minutes researching the answers to your own questions before going on the internet and arguing that environmentalists don't have any answers. There's a wealth of information out there, and lots of people who are trying very hard to educate people, who would be happy to educate you if you asked questions in good faith, or typed your questions into a search engine.

You can do what you can to reduce your own carbon footprint and you can join organizations like the Citizen's Climate Lobby (https://citizensclimatelobby.org/) to convince politicians to finally start acting. These people here (https://www.drawdown.org/) put together a list of actions, some of which require you to change your behavior, some which you can influence by getting involved in local politics, and some which require global action.

In terms of global average temperature, we consider "average temperature in the decades before industrialization" as "healthy/fixed" and the previous temperature plus 4-6 degrees Celsius as "broken beyond repair".

In reality it's of course a bit more complicated since earth is complicated. Another good proxy for "fixed" would be "glaciers and permafrost exist and are not decreasing" while broken would be "large areas in the third world have become uninhabitable to humans"

We have very little understanding of the range of temperatures that are "fixed". We know for sure that at pre-industrial levels of greenhouse gases in the atmosphere and at that temperature, the complex ecological systems of the world were more or less sustainably living.

Here's an opinion on it.

Haven't gone out and done my own validation, or checked other sources, but it'll give you somewhere to start

Alright, I'm not going to entertain this charade where you just pretend you are "trying to learn" any further. Crap or get off the toilet: either state your disagreement with what I've said, or don't.

I'm not arguing that there's some "ideal Earth temperature": that's your straw man argument that you're making and has nothing to do with anything I've said. I don't need to provide data to prove a claim I never made. I've made three points, numbered in my previous post. Two have data behind them, and the other is fairly self-evident. If you'd like to share which of the claims I've actually made that you disagree with, I'd be happy to engage you in a discussion where we present evidence for our respective positions, but I'm not going to answer you if you continue asking me questions of the form, "Why can't you provide evidence for this claim you never made?"

It seems that you have a number of threads going on here that are deliberately argumentative.

Clearly you haven't even had the time to read any of the references that you were specifically given that answer many (if not all) of your questions - yet here you are, continuing the climate-denial fight.

Do the honorable thing and stop phrasing your statements as questions - it is a waste of peoples time answering them.

Socratic trolling doesn't make you some grand truth fighter; it's just a pose you think is clever because you can conveniently demand answers without stating any positions, skip reading any references, repeat the same question, and proclaim victory when people get annoyed at your duplicity.

Just to make it explicit for the audience: before he was claiming just to be an honest truth seeker looking for references to learn about the topic, and now he acknowledged he's just a troll. Which was obvious from the start, but worth pointing out.

"...demanding they stop using plastic straws by showing pictures of turtles."

You do realize the plastic waste issue is separate from climate change?

I'm afraid that, since you seem to be reasonably intelligent and informed, I have to assume your replies are not made in good faith.

> Every time I try to argue around the subject and ask questions about it I get downvoted to oblivion or get answers like yours.

That's because you aren't asking questions, you're making vague points with question marks at the end.

> If these people were actually worried about climate and all related subjects they would be working on providing actual things reasonable people could do to help as oppose to calling other names and demanding they stop using plastic straws by showing pictures of turtles.

One thing actual reasonable people can do is stop pretending climate change doesn't exist and isn't a problem.

then instead of asking questions you are not interested in the answers to, give evidence of your own position.

I'm not here to argue with you. I am just pointing out that people are linking you to references, and you clearly aren't even reading them before you post your follow-up "questions".

If you want to argue, argue with evidence - don't dress it up as a question.

Are you replying to yourself, or is HN broken?
